Mastering Object Manipulation in Blender

[Music] let's learn how to add and delete different types of objects in blender as well as adjust their initial properties it's kind of a meme in the blender world that in order to start any project you have to delete the default Cube I don't know what the cube did to deserve this but first let's go to the object menu with the cube selected and down to delete click on that and our cube is no more we can also delete objects by selecting them and then right clicking and using the last option in the context menu also notice that in both of these instances the hotkey x is listed to the right side of the delete command so we know that X is also the hotkey for delete let's try it out on this lamp let's select it with left click hit X and that'll bring up a popup confirmation just to make sure that we really do want to delete this lamp the x hotkey is next to several other important hotkeys and it's not one that we'd want to hit by accident so just left click again and now our lamp is deleted I'll hit contrl Z a couple times and that way I can show you a couple more things about deletion first is that you can also delete with the delete key on the keyboard that's pretty intuitive just select an object and hit delete simple enough there's no popup for that one it just deletes it right away I think because you're a lot less likely to hit that one by accident you can also delete objects in the outliner for that go over to the outliner select an object either rightclick and use the delete in the context menu or you can use the x or delete hotkeys so lots of ways to delete things in blender to add new objects of course we go to the add menu let's do that in the 3D view header and to bring back our Cube let's go down to mesh and cube in the ad menu we have a bunch of different sections for the different types of objects that blender can have all of these types of objects have different purposes and different use cases besides mesh objects which you're going to be working with most of the time we also have curves which if you've ever used a vector application like illustrator or inkscape you'll be pretty comfortable working with these we also have nerb surfaces which some of the old older 3D artists might recognize though they're pretty weak in blender so I wouldn't recommend using them like in other apps below that we have metab balls which let's just take a second to add a metaball ball and appreciate how weird this is if we add one of them it's not that interesting but if we go to add a second and bring them close together they'll just start to gloopy meld together and while the use case for this is admittedly limited sometimes it's an incredibly cool way to make weird shapes so take a second to mess with those but then we also have text volumes grease pencil which is the object type for 2D animation in blender which we'll look at in a later lesson we have armatures and lates for deforming our objects we have empty objects which are just used for Organization for the most part and images and lights and all sorts of different things for now though let's just stick to mesh objects I'll go ahead and add another Cube here and you'll notice that it got added right to the center of the world and in fact all of our objects that we've added so far have been added right to the center that's because new objects in blender get added to wherever the 3D cursor is and the 3D cursor is this little crosshairs life preserver icon that happens to be right in the center of the world at the moment but we can move that to wherever we want one way is to use the 3D cursor tool in the toolbar so that's just under the selection tool again it's the crosshairs with the life preserver and if we select that tool then we can left click anywhere in 3D space and that's where new objects will be added so if we go to shift a and add another Cube then that's the new spawn point you can also change the position of the 3D cursor while you're using any of the other tools by shift right clicking so here I'm back in the selection tool but I can place the 3D cursor by just holding down shift and then right clicking anywhere in the scene and you'll see that if I shift right click on an object it'll be snapped right to the surface now let's say you accidentally place the 3D cursor way off into space and it's actually really hard to do too far but let's say it's just way off there and you want to add something right back to the center and let me go ahead and get rid of these these two cubes here just to make this a little bit more clear let's say we don't even know where our 3D cursor is and if we add a new object then it's just it's gone so I'll go ahead and contrl Z undo that so we don't add something out in the middle of nowhere and in order to get it back instead of just trying to shift rightclick you know right in the center there we can actually snap it right to the center by going to object and snap and cursor to world origin so that's a really helpful option just to bring it back to exactly 0000 0 we can also snap it to object by selecting the object and then going to object snap and cursor to selected some of the commands in that menu are used so often that there's also a hotkey for it which is shift s this isn't one that I think you need to memorize right away but it can be helpful if you find yourself using it a lot so just to practice that once I'll hold shift s and then in the bottom left I'll go cursor to world origin to snap it right back to the middle then another option in that menu is to bring the object to the cursor for that I'll hold shift s and swipe up to go to selection to cursor cursor now our cube is right back at the center and that's really helpful if you accidentally let's say hit G just move it off somewhere and you want to center it again then you just need to place a 3D cursor right at the center hit shift s and go selection to cursor or again you can use object and snap now after using some of these operations you might have noticed in the bottom left of the 3D viewport we have the name of the operation listed in this little box if we click on this we'll expand it and see some options this little panel is called the adjust last operation panel and if you never see it then you'll probably need to go to view and just turn on adjust last operation this is especially helpful when it comes to adding new objects because we can set some of their default properties let's go ahead and move the 3D cursor out from the center and add another Cube shift a mesh and Cube and now with the adjust last operation panel expanded we can see that it has a couple different options we can change the size how it's aligned the location and the rotation I'll skip over over the UVS for now because that's a topic for another day the important thing to know though is that as soon as you click off of the cube or select any other object or just do anything else in blender that panel is going to disappear and you're not going to be able to continue to adjust those options let's just say you've clicked off and selected some objects but you haven't rotated or scaled anything then you might be able to get that menu back just hit F9 now in all of my clicking there I did some other operation and it's not coming back but often if you just do some operation like adding or moving and you click off to the side and that disappears then you can just get it back by hitting the F9 hotkey that'll bring it up and you can continue adjusting it from there some of the other default objects in blender have a little bit more interesting settings than the cube so let's take a look at some of those I'll go ahead and delete these cubes here just by hitting the delete tot key I'll bring my cursor back to the center by going to object snap and cursor to world origin and then I'll hit shift a mesh and this time we add a Taurus this one has a lot more settings and this is adjust last operation panel is where we'd adjust the number of segments that go around the outside the number of segments that wrap around or how large or thick this doughnut shape is again once you've clicked off but before you do some other operation you can always hit F9 and bring that back all right the last important thing about adding objects is that you can also do it interactively from the toolbar if you choose this last tool here at the bottom that's the add Cube tool and you can just left click and drag anywhere in the 3D viewport that'll create the base let go and then drag up to create the height and then left click again to confirm what's cool about this is that it's snapped to the surface of whatever you draw on so I can draw a cube on the side here and since this tool has a little notch in the bottom right then that's how you know that there are more tools inside of it so let's left click and hold on it and now we can see that there's also an add cone tool that works very similarly which by the way these tools have a couple hotkeys if you're familiar with working in any image editor it should be familiar to just left click and drag but then hold shift in order to constrain the proportions or hold alt to drag out from the center rather than from the corner or you can hold both at the same time there's also tools for adding a cylinder a UV sphere or an icosphere the difference between those two is that an icosphere is made of triangles while you sphere is made of mostly rectangles after you've added one of these objects though you might be tempted to go up here in the header in the tool properties and change some of the properties like the number of subdivisions here on the icosphere but as I slide this around you'll notice that this isn't changing anything that's because this is the tool properties and we're changing what we're going to do next to adjust what we just did we have to use the redo panel like we just talked about so you can see that here the subdivisions is set to two and I can change that at will but that's going to be different than the tool properties which determines how the tool is going to to behave when I use it next time all right I think that's enough information about adding and deleting objects to get you in trouble so now before you move on to the next lesson I want you to practice this a little bit go ahead and use these basic shapes either from the shift a ad menu or from the toolbar and make something super simple whether that's a robot or a snowman or just something from your imagination it can even be complete nonsense if you want but just get comfortable with adding deleting and placing the 3D cursor I know you don't watch these videos to get homework but I promise you that getting these things into your muscle memory early on will be very helpful for what we're going to do [Music] next
