so product means it is an assembly window I told it Sketcher for design wireframe assembly so product means it is assembly window so by default this assembly window will open so you should close that okay by default assembly window product window will open you can close that so now we are going to see the Sketcher window right so for that you have to go to the start mechanical design so in that n number of submarines are there so we are going to see only five modules sub modules so Sketcher part wireframe and surface design assembly and rafting only this way you are going to see okay now we will go to the Sketcher okay so after closing you have to go to the start mechanical design Sketcher simply select ok actually this is the part window only but this is the Sketcher tool so all other tools are in normal color but it is highlighted in the orange color okay this is a Sketcher tool so you have selected the Sketcher so this tool is selected so if you don't know what is the next step you want to do you can read this this bottom line the left corner lowest corner select a plane or planar phase or a sketch okay so sketch tool is selected now we have to select on which plane you want to draw whether it is X Y plane or is that plane is it explained here or here anywhere you can select okay so I am selecting this Y is a plane now this is the uh Sketcher window I'll tell you I'll tell you the important toolbars so this is the blue toolbar then second I told profile toolbar actually you can drag anywhere okay and if you want to uh yes and if you want to change the orientation from Arizona vertical to horizontal simply you have to select shift okay if you select the shift the orientation will vary I will I will change now also it is material I'm pressing the shift so it is changed constraint and this is finally or bench okay so view toolbox profile operation constraint or bench additionally we have sketch tool so your voice is coming too low too low okay what happened uh while pressing shift control under I have to use both hands in the time my headphone is falling so this happens now is it fine yesterday okay so first tool is view toolbar you know that so it is fit all in band rotate this is basic almost in all panes after you can get this type of toolbar so it is easy so second one is profile using this you can create the continuous lines for example you see I can draw the straight line okay if it is inclined it will be in white color if it is straight horizontal or a straight vertical it will be in blue color okay so I can draw the horizontal line inclined line then now you see sketch tools previously only these five tools are there now it is expanded so here you can select whether if you want to draw the arc so like they're continuously you can draw the lines and if you want to terminate the same tool you have to press otherwise here you can press the escape button so that you can terminate the next one is rectangle if you expand you can get a number of rectangles so oriented rectangle parallelogram or a limited whole Keyhole so elongated then Circle and different types of circles Three Point Circle coordinate Circle tangent Circle then different arcs then spline spine means like uh some small profile like error file profiler you can create it and the main important thing while running the profile is so always after create some Auto constraint you can see I'm keeping the point here there is nothing extra lines coming but now you can see one horizontal blue color line and that line shows coincidence with this rectangular horizontal line you can see now see okay so there is a auto constraint now in face select now if I terminate by selecting this you can see this whole symbol that means this point and this line there is a auto constraint okay coincident constraint so what will happen due to that you see I can move this point I can move this point because it is not at all constrained anywhere but this point I can't move actually now I could move because it is not fixed once it is fixed now you see vertically it won't move the state may move particularly to it won't move like that sometimes there will be a harder constraint so when you design the profile you should be careful there should not be any auto constraint if you want to delete simply you have to select that icon and simply press the delete delete button even if you want to delete this line simply select and press the delete okay it will it will be deleted okay then here leaves if we expand you will get hyperbola Parabola those things then line then access line access line is just for our reference okay so software will not consider these lines for example if I exit this Sketcher and go to the part design you see that access line is not there okay so it is just for the reference but this point you should be careful you should not create it unnecessarily I actually took uh create the 3D for example if I don't want these clients simply I am doing the Box selection and deleting it okay you can delete it so if you want to create the 3D model then the profile should be a single closed curve so this rectangle I can convert this into a rectangular box but if I create the box like this if we create the box like stay like this I cannot go for the 3D because there is a opening sometime in this distance may not be usable if we normally see it will be like closed you can see now you see it is completely closed so all the points are in white color but this profile you see it is closed this through by these three points so it is in white color it is not closed so it is in uh black color so these open profiles cannot be used for the 3D design and also so only one profile should be there if if you take two profiles like this which are intersecting and you try to do the 3D it won't work okay so 3D works in the different way so if I give on 3D model so each each projection each command separately you have to create it okay so this is about profile tool how to create a then operation toolbar so using this corner you can convert there is you can select these two line or if you want you can select the corner also you can convert sharp edge into the rounded Edge or you can convert sharp edge into the flat one using chamfer sorry and if you expand the third one the limitation in expand the fourth one transformation you can expand the fifth to one 3D geometry so a number of options are there so this is like trim this is break this is quick trim so if you want to break the line this line if you want to break it with reference to this axis now you see it is two lines accepted as a two lines okay about this access it got separated our trim there is quick trim mostly we will use this quick trip that is unwanted line you can delete it for example mistakenly you have drawn another one profile like this okay so you don't want these extra projections so simply select it will be deleted so up to intersection point it will be deleted for example here if I select this it will be deleted between these two intersection point either you can delete the unorder lines so mostly with this quick tree we will use it okay then transformation if you have one profile you can do the mirror that is mirror image you can create and we can do symmetry we can translate rotate we can increase the scale we can offset all those things we can do it okay offset means for example this is the profile so this is the profile so if you offset you can see the same profile we can reduce the size or increase the size and again this sketch tool is expanded here you can give the value of the design whether you want to offset it outside or inside that you have to decide for example if then this blue color line it is showing right so it should be in say it should not keep it outside okay it should be inside in that case you can move it a little bit this one your move is the regular line is inside now we can Define astronomy so for 20 mm distance it is offseted like that you can use these tools and all then constrain so this is to give the dimensions for example so this line I am selecting so I am getting 397.482 mm assume it should be 400 mm okay we can change it okay then this this critical line I am giving it is 239 so just double click to change it give it as 300 either you can change it okay so you have to give the dimensions foreign thing okay these things I will close it okay so I am going to give the dimension for this rectangle so we know for rectangle these are all the two major dimensions lengthen width or height anything you take I am taking this as 400 and this is 300 or 200 something I'm taking on rectangle so this is the required Dimension right for rectangle only two elements are required actually after it is constrained this white color line will be turned into green color with that fully constrained Greek green color line profile only you have to take you to the 3D design okay because so anytime you can read it the design for example uh there are 10 20 steps okay n number of profiles you created for the single common end at last you are coming to this first profile you see it is movable anywhere so mistakenly you selected and it is smooth and you can update it every time it will be automatically updated now if you exit and go to the final command because of this movement totally there will be a discussion happen in the final decision so always when you create the profile we have to constrain it properly so it should not move anywhere so how to do the constraint means Dimensions we are given then we have to r as the degree of Freedom okay it should not move vertically horizontally so those areas RS thing we can do it with respect to these axis lines okay so you can fix the rectangle like this in the center or at least at some just a certain distance or even at the center like that depends upon the geometry you can fix it for example I am going to fix this rectangle as a symmetry with respect to this axis I have to use both hands so if you are facing any rdsc please let me know okay so it should be in the center that is it should be symmetry about the surface so in simple way if you want to use a cement remains what you can do you can select this constraint you can select the line and the access I am getting additional dimension since I can leave 100 we'll see if it's constrained similarly here also I can give the distance so it should be 200 now see it is completely constrained green color and if you try to move on so it is not moving anywhere like that you have to consign the profile then only you should go for the 3D design but here it is 200 so I easily given 100 but if the number is large and complex that time it is difficult to find what is the half value so in that case you can go for the another consent method for example this is symmetry rate that is these two lines are symmetry about this axis okay so these two lines first then preference axis both I got selected and if you want to continuously select you have to press the control otherwise if you select one time and next time if you select this it will be gone so continuously if you want to select because the control then you can select okay two outer edges and the reference access now you can see First Tool is uh opened enabled so constraint defined in dialog box that you open you are getting a lot of options symmetry tangency coincide parallelism so here we need this symmetry select now this is the Symmetry symbol now see these two lines are green same way I can use symmetry for these two lines with respect to this reference line now this is enabled I can give symmetry okay so like that you have to constrain for example you are dying another one Circle here you know for Circle only the radius is the only Dimension if it is 500 and it is moving here and there now we have to address the uh moment assume the circle line is tangent to this vertical line so we can give the tangency for example select this line select this circle now first tool is enabled you can give tangency okay now these two two lines so parallel line is there that shows the tangency still it is a white color that is because this Center Point is not fixed okay so how can we there is horizontally it won't move only vertically it is moving so what I can do any idea how to fix this assert that parallel to that axis uh that's the internet yeah good so we can make this line parallel to this that is coincidence okay I am selecting the center point and this axis so first one is enabled I can give coincidence okay so this point coincided this success now it is in green color but still we can't use this profile for the 3D profile because there is intersection okay at a time it should take only one profile that would be a better okay this is about the Sketcher toolbars so this is to exit this sketch okay this is the part design you can convert the profile into 3D because we will see it in the next class so okay now we will go to the bulkhead design so the bulkhead design we have to draw the two concentric circles with a radius of one two five zero one two two five so this is the circle tool okay so I'm drawing the first Circle uh simply I'm trying on Circle later I can Define the dimension see it is diameter what we need is the radius okay so you can change the diameter into radius R this value you can run it into diameter energy is possible okay whether I am taking radius itself and value is one two five zero okay so first Circle I have run but it is not fitting into the screen so I can use this fit all in tool now it is fitted now then go for the second Circle whenever you draw our profile immediately you do the constraint it is not like after drawing two circles to eliminated holes everything it should not constrained whenever you draw on profile you have to concern it I am giving second dimension radius one two two five so two circles I have drawn then we have to draw this two elongated holes any idea how to draw that you see from here to here it is a semicircle then from here to here it is a straight line for 600 mm and again here it is a semicircle sorry that is not talking foreign there is no restriction n number of phase are there okay you can draw the profile in and whatever the way you want so as you said you can draw one rectangle then you are telling we can draw one Circle like that right now we can hear the dimensions for example this radius is 800 and this should be the 1600 1600 and this they are mentioned 600 which we created okay as you said we can create another Run Circle also further also we can Define the radius okay it is for constraint now we can delete the unknown deadline right so we can delete The Unwanted lines so you got the profile actually if you want to continuously use the tool you can double click okay if you select only one time only one time you can delete it but if you double click continuously you can delete it okay all the tool Works in that way okay as you said we have created this profile okay two circles but it is not constrained how to constrain just move it any idea how tall is the moment so this from the axis we can fix the distance of that yeah so from the axis to any point from here to here or from here to this point or the center point anything you can take it okay anything you see anything you can take it it's up to you for example this 0.2 this point so see sometime you will get these inclined Dimensions but in the cation you should avoid incline dimensions so if it is coming in plane simply right click then you can convert that into vertical or horizontal okay so vertical you can convert 300 okay still it is in white color why if you don't know simply select the white color line try to move it then you can find what is an issue now what is an issue sir one is not a tangent one yeah right so I can do control set okay to reversal control y controller control y one will work okay so here tangent is missing I can give tangency to give tangency it say it tells four constraint okay if if additionally if you are giving constraints it will turn into pink or red color that means over constraint so the constraint is not necessary it is selling unit of tangency already it is constrained then you see this point is moving okay when I move this find is moving so it has to be fixed if I can give same 300. from this point to this axis okay like that you should find which point is moving but find the outer state is it clear hello yes sir okay so this is the normal way of uh drawing it but once we explore all the tools so we should work as the smart worker okay you see how much time we spend we have Grant rectangle two circles then we deleted a given lot of diamonds inside it takes so much time as a design engineer so you should know Willow support all the tools and you should know which is the shortest way to draw the design so now you see instead of this method if you expand this rectangle you can find the elangated hole so what it means is just two Center points okay so the center point is will be in the vertical axis that should be a bone below the axis okay because the profile is symmetry about the axis now see with a single tool I have created the profile and this is the radius what the invention is 800. and this land there given us 600. okay now it is moving here and there now instead of giving Dimensions as I said it is symmetry about the axis I can select these tools and uh profiles names and this reference access for the first tool you can use symmetry so these Dimensions you can change it anywhere if you click the line you can move it anywhere if you keep this the value you can change it anywhere okay now you see how simple this diagram previously there will be lot of Dimensions Etc given right now you see with the only two dimensions and the symmetric constraint we have created now if you give this diagram to the manufacturer he can easily understand is it clear so we should avoid necessary Dimensions your diagram should be clear with a minimum minimum dimensions okay now same way you can create the another elongated hole another option is that this offset option is there but offset option will take again more time for example if you select this offset sorry first you have to select the profile like this profile I want to offset so select this offset tool that is if we expand the last one is offset so I want to offset it inside because the radius Dimension is 780. so keep it inside then come to this Sketcher tool so 20 okay because 800 minus 780 20 now you see it is created okay but it is in white color now what you have to do you have to give radius tangency vertical for example this line also if you check you see it is changing inclined okay what you have to do select this line select the first one give vertical like that we have to give the all the diamond cells so it will take so much time even though we have created the profile immediately but constant will take more time so I'm not going for this upset pay instead we can create it once again so already I know this reference points so State a I'm selecting the point okay instead of giving symmetry already the points are there straight away I'm selecting on it AC will creating you see it is trying to create tangent with that Circle also an horizontal constraint with another object like that lot of Auto concern is there those things you should avoid it okay now it is not there is no Auto constraint little bit you move there is auto constant those things you should avoid okay now it is clear I have selected this should be 780 now it is fixed okay so you should know uh which tool sometimes the offset may be the better option but here creating again is the better option like that you have to decide okay these things you will get it uh once you practice more and more on this software is it clear in it out in this uh certain that first bulkhead uh you have applied three constraints because like the Symmetry symmetry I have applied second time what what I did when I create we have to specify these two points okay what I have done this point I have coincided with the existing point while creating itself for example second time when I created I have selected that point as the reference so there is already Auto auto constraint like that I have created so the Symmetry is not needed okay so that bulkhead can be moved up or down also now because like if you uh like make the point in the symmetric line also but like they can now see I am trying to drag it it is not moving see it is selected it's not moving I will repeat it if you want actually how you will create okay for example here on point here on bind I'm keeping then I am drawing the profile in that case I have to define the radius 780 and this is 600 or 600 I have to Define now it will be moving in the very real Direction now what I have to do I can use the Symmetry between these two profile and this axis if I give that symmetry you see these two points after giving symmetry these two point will be coincided because yes both profits have the 600 only okay so both point will go and say automatically so I know that the point will be coincide after I give me after I give the Symmetry now also you can try see I am giving Sigma 3 now you check the points it is coincided it is a single find now both points go inside right yes so you can create it instead what I have done while creating itself in the art of coincidence for example so center point I have to select instead of selecting anywhere I get selected on it itself there is auto constraint similarly I asserted this point so there is auto constraint in that case monitor of symmetry simply H and G only the dimensions yeah okay so these things symbol when you practice you will come to know how to reduce that steps otherwise you see I have to give additionally symmetry but I have our end okay okay Mom so now we have to create so these four circles uh so these two circles they are 100 these two Auto circle with the 75 and distance between is 400 350. so that let's design it so the circle I am drawing it so I should not write actually sometime what will happen your profile will be turned somewhere like that in that case you can use this normal view so that we will get the again parallel view okay so Circle I am drying you see the circle it is not in the axis it is above the axis totally 400 means from the axis to center point it is 200 you see if you try to create the center point here there is auto constraint coincidence with the axis so it should be above to that and you draw the circle you see now there is a coincidence between these two lines tangency okay so those things you should avoid there is no Auto constraint now you can Define the radius 600 and they have mentioned distance between the center point and the axis is 200 and they have mentioned the center point to vertical axis is thousand so that also we can give thousand okay so first the circle we have drawn okay then second Circle just above to that here also it should avoid the auto constraints you can see there is auto condition between Center Point and this those things generally you should avoid now there is no Auto constraint is 75 and distance between these two point they have mentioned 350 but here I am getting the inclined angle so right click change to vertical now this should be 350 and since between the center point and the vertical axis is 900 I have drawn the two circles then for the remaining profiles I can use the mirror images Mirror Image okay this operation toolbar fourth one if you open a stone is mirror so that I can use it so before that I should select the profiles so press Ctrl thank you then select the mirror tool if you don't know what is the next step you can read here select the line or access okay so which we are taking as a reference it is asking so we are going to take this horizontal line as the reference so we have created four circles and same four circles we have to create it on the left hand side also so again I can use the mirror tool so select R4 circles then select the mirror tool now select the vertical axis now it is created okay and you have to ensure these Dimensions not crossing the diagram not affecting the diagram if you want you can take it inside okay now the same is created at last what student will do they will go to tools image they will capture this then they will attach it in the observation so select the capture so this icon will be there in the third one is the options you can change the background etcetera and all you can see you go to the pixel you can select white background if you don't select the white background so first button is the capture if you try to capture it is capturing again minus old laptop so it is taking time see after capturing I am getting this uh light blue color or Ash color background it is not visible properly so we can change the background using this uh options so I need a white background I need highest quality those things until you can change it now if you capture now see it is the white background even you can save that as a one I'm saving it you can check it okay the profile is saved this they will crop and take the turned out they will attach it in the observation then they will write the procedure Supply they used to submit that's it another important points so in the sketch tools so if you want you can enable the grid Point grid grids okay if you find it if it is useful I work with without grid only then second one snap point there is snap snap to point if you select and if you try to create any diagram what will happen you can pick the point only in the grids okay you can't said okay sometimes after I will it won't work in that same way so actually snap to point means you can pick only this grid intersection points okay so mostly I used to disable this so that you can pick anywhere in the grid points okay these two I don't use it mostly and another important thing these five should be always enabled okay so see uh this is dimensional dimensional constraint geometrical constraint results almost same okay dimensional geometrical instance these five it should be enabled for example with that enabled if you draw the profile automatically it takes vertical horizontal Etc under and if you disable these things now if you draw there is no vertical horizontal and if you try to move you can move it okay but these things it is not moving okay it will become it is enabling these constraints so always you have to ensure these things are enabled okay okay these five should be enabled and this one is just a construction line for example uh this is a solid line rate by selecting the solid line and this thing we can convert that as the reference line using this option it is mostly it won't be necessary because we have the access at all separately
