welcome to part two of three part civil 3D beginners video series if you missed part one then click here to check it and if you want to learn civil 3D right from scratch with full length Project based courses then click the link in the description of the video or print comment with that let's get started [Music] okay so now that we have a little bit of an understanding about the interface and the settings and how civility works with Styles let's kind of get our road done let's first talk about project management all right so the first thing we're going to talk about is this existing ground surface that we have so this surface came from our surveyors if you want to kind of take a look at it real quickly this is the existing conditions you can see here there's a road we're going to put our road over here because we're doing a bypass the cool thing about this project is this this is actually completed if I were to turn on my geolocation and we'll set the Aerials on here you will see that this project is already done this was uh pleaded in construction about uh two three years ago and this is a project that I had worked on and if we zoom in here let's just turn this off real quickly we'll just isolate it and hide it you'll see that this project is actually done this is pretty cool right so this is the existing conditions and we're going to actually do this road and basically you know so you can see kind of how fast this gets done in civil 3D let's go ahead and just bring our surface back here all right okay so what we need to now do is I need to set my working folder to the location of where my project is located so my projects are located in here we'll just click select folder now what it does by default is it finds the first folder within that folder that has an underscore shortcuts folder okay but what I want to do is I want to put this in my project folder so I'm going to right click here and click on new data shortcuts project folder now all I have to do is type the name of the main part of my folder which is called three-part tutorial so I'll type that in here right now so three dash part all right I'm not going to use a project template but you could now I'm going to click OK here and watch what happens immediately this updates with the location of where my project is going to be so I'm going to open follow location here let's open up my Windows Explorer and as you can see what it did was it created a folder called underscore shortcuts and inside that folder is simply subfolders that allow me to contain the data shortcuts which are simple XML files they're literally just text files that point to the location of where the data reference is so the drawing that we're going to be working in is in drawings okay and then my references which this is existing ground is located inside here so now what I need to do is associate this file to the current project I'll click OK here you'll notice up here it now shows that it's part of that project and now I'm going to make a data shortcut for the existing ground surface so that I can bring it into my other project files so if I expand services and look at EG there it is and again all that this does is it creates a simple little text file that points to the location of that surface that is it now let's go ahead and begin our project now we're going to do everything else in this file normally I would create a separate alignment file then make a data shortcut and then maybe make a separate model files and then data reference in all the other objects I would need but just to get this tutorial done let's just bring in the EG and let me back up here let me just show you what we're starting with we are starting with nothing and that's what I really want to show you here I'm going to do a control a and if you look here at the properties I've got five circles just to help me kind of get the alignments in there real quickly okay but that's basically it here so first off let's associate this project to the current drawing which is this part two drawing that we're in again now you see it up here and now I want my EG because I'm going to need that to see it for my profile I don't need it to display I don't really care I'm going to set that to no display now let's go ahead and go to the AutoCAD reference and let's bring in my DWG which is my Topo file okay this is the existing condition again a surveyor located all the data for us so that we can see what needs to be done so the background of this project is there were way too many trucks coming into this gas station in this area right here and it was clogging up this intersection horribly this is a DOT road this is basically a state road okay and they were telling the county you have to take care of this and so they hired an engineering firm to create a bypass road just for the trucks to enter and then come into this way and that way they wouldn't clog up this entrance they exited a different way as well so they would come out this way and then just the exit's fine but they cannot turn into this here and that's the main purpose of this project so as you can see I've already drawn some circles to kind of guide me into creating my alignments and profiles and all that good stuff stuff all right so basically let's create the mainline alignment first and then we'll create the Side Road alignment here as well okay so let's go ahead and go to the Home tab create design panel alignment alignment creation tools we'll call this one US 129 because that's the name of the road always start your stationing at 10 or 100 plus 0 0 so I'll just start at one hundred plus zero zero I've got my Styles ready to go label sets ready to go click ok and I'm off and running I need one tangent as this is a straight Road in this location so I'm just going to do tangents I'm going to go ahead and go to the center of this circle here and I'm going to go to the center of this circle here again this just guides me but as you can see I'm pretty much just going between the midpoint of the road to the midpoint of the road that's it all right so that alignment is actually done now so let's go ahead and go to alignment alignment creation tools and this road will be called loves bypass as this is a Loves Gas Station so Love's bypass and we'll start this one at 200 plus a pair this way you never repeat your stationing again notice how it's getting its own layer because the settings are ready to go it's got the default Styles ready to go click ok now for this one I'm going to create two tangents and then I'm going to fill it in between them so I'll start at the center of this circle here so I'll start at the center of this circle here and we'll just go from here and we'll go to the center of this circle here again based upon the design criteria and the avoiding of all these utility poles as you can see it's a pretty major line here that's how we initially designed this road and then I'm going to go ahead and continue this I'm going to go from here and I'm going to go perpendicular to my new alignment press escape and now I've got my first tangent labeled but this is not labeled yet because this is not connected so let's go ahead and do a free curve fill it between two entities radius we'll go ahead and select our first tangent pick our second tangent and then it's less than 180 press enter and the radius I want is 250 press enter and now I'm ready to go and it's that simple that's how you create alignments again there are multiple ways to do things as you can see by the alignment layout tool there's a ton of these fixed floating free methodologies you can even do spirals if you need to and so on so now what we need to do is we need to create a profile for our alignment so we'll create a service profile first we're going to do this for both so I want to add in the EG and I'll click drawn profile view and I'm going to go ahead and pick the profile view that I want here which is this one here and we'll click next next just going with the defaults I don't want anything to be labeled we're good we'll just create the profile view this is for us 129. now I want to do the same thing for the loves bypass so we'll click on here pick my alignment We'll add in the EG and then we'll go ahead and click on draw and profile view and we'll click the style that I want click next next we'll just create profile view and then we'll just put this one over here so let's first design this one so what I need to do first is I need to trace the roadway because we have to start from there and then I'm going to have other locations where I have to trace as well this is a pretty simple Road and basically what I need to do is to make sure it does not go above the maximum stage for this pond so this Pond is already here and the maximum stage is 154. so simple 3D provides these really great tools called transparent commands where I can actually draw stuff in civil engineering I just started the line command here and I want to start at two hundred zero zero press enter and I want an elevation of 154 press enter and I'm going to press Escape once because now I can use polar tracking to simply draw this line going straight across this lets me know do not get your profile below this elevation because the road will get wet so let's go ahead and select my profile view and we'll go ahead and click on profile creation tools I always get my proposed profiles an underscore so underscore loves and we'll click on OK here and for this here I'll simply start just drawing tangents because I can change this afterwards I want to start here and then basically I want to eventually I have to tie into this road here but I also need a grade of point three percent so I'll go ahead and go to the transparent commands I'll click on grade length and then I'll select my profile view and the grade I want is negative 0.3 that's my minimum grade that I want now for a length I don't know what that's going to be I can simply click in space as you can see it's letting me just draw that grade in there and I'll just go ahead and click it and then press Escape once and then I will go ahead and snap to the endpoint of this location here which is my center line You'll see why in a second why I'm not going to care about the rest of this in the middle here all right now for this us-129 because I want to do intersection design I actually have to trace it it does not work with a surface profile and that's okay so let's go ahead and select this we'll click on profile creation tools and we'll call this one underscore us129 press enter notice how the profile layout tools update I will simply draw tangents and I'm going to trace the surface profile here so I'll trace this here let me turn off polar tracking and we'll just trace this okay so of course I didn't want to trouble you guys with showing all that so as you can see here I have a completed profile okay and now what I'm going to do let's go ahead and turn off my Topo because now we know exactly where everything needs to be and what I want to do is create an intersection at this location right here so let's go to the Home tab intersection create intersection let's go ahead and zoom in okay so of course I went through and just created all these I don't want to bore you guys you know placing pis all over the place so that's all done and now what I need to do is create an intersection at this location here where this alignment intersects that one okay so Home tab intersections create intersection all you have to do is zoom into the location of where this exists we'll click here it picks it up automatically and notice how I have a setting that already gives it the right names that I want to we'll click next here there's my main line and my side road which is important for priorities if you go to offset parameters you can change the width of the roads here but we're good to go and we'll go ahead and click on curb return parameters and my radii that I want is 35 we're going to have some truck traffic in here so we want to make these pretty as large as we need to and we'll click OK here all right and now we'll click next and I want to create a corridor so we'll create a new quarter model we're going to use these defaults but just so you know you can change these to whatever custom assemblies you have for your project let's click create intersection we'll press Escape notice how it is basically done that's how simple this is now if I zoom in to the different spots where the assemblies are you'll notice that some of these assemblies don't actually have the curbing gutter which I may need them to have so I've got this curbing gutter there and I've got none over here what you can do is very simply open up your tool palettes so these are being used by the quarter model and I can simply grab the sub assembly that I want go to the properties palette I'll verify that it's set to left as I always say when you don't know what to do look to the command line window it says insert replace or detached so I want to insert and I want to zoom in here and I'll go ahead and click over here and notice how it inserts the curb into that location there okay I could then press Escape once and then zoom in here and continue the process and press Escape now as you can see though the day lighting is not going to the right location that's okay select your sub-assembly and simply click the move in the contextual ribbon click up here and now it's over there I'll do the same thing below here select my sub assembly click move zoom in click here and now we're ready to go now of course I'm not done because I need this to be larger right I need this to go all the way down to the location of where I might do an intersection at this location just for time constraints we're going to skip that but as you can see here the second I pick that grip all I have to do is rebuild my quarter model it automatically finds a targeted surface and everything I can do the same exact thing with this one here I'll go ahead and click here and I'll pull this all the way again you would probably pick a station of where this needs to go and I would do the same thing over here and pull this up over here now let's say though I want to widen this side of the road so I'm going to go ahead and select this offset alignment that was generated from the intersection tool so I'll go ahead and select it and I'm going to pull this offset alignment all the way down to the beginning or somewhere past it I'll do the same thing on this side here and we'll go ahead and select that and pull this down here now let's say just for this part of the intersection I want to create a widening I can simply select my offset alignment I can click the plus sign here and notice how I now have a widening I'll drag this widening to the station I want to go to so let's say this has to go to 10500 I'll press enter it automatically puts it at that location I can then click these two buttons right here and click this button and then Define where that taper needs to end so I'll type in 106.00 press enter 100 feet later and we'll do the same thing on this end here if I wanted to let's say end that widening I would simply click here and then I'll drag this one 12 feet that's the width of my Lane and then we'll pick this location here and this should be at let's say 111 plus a pair we'll click here to expand those grips and I'll pick here and I want that to be 1 10 and now for this one here I want this offset to be 24 feet so I'll click on there type 24 press enter now here's the cool thing because the quarter model was done with the intersection tool it already was targeting that offset alignment you are done now what I like to do in these instances is to select my quarter model and create a quarter surface this way I can see it in 3D a little bit better to make sure everything's working good we'll call this one rode this is my top links I'll click the top one click the plus sign add his break line go to boundaries right click quarter extensis boundary and click OK and now if I press Escape here and select my proposed surface and take this into the object viewer as you can see this is a completed Road within 20 minutes now would it need some tweaking and possible ditches or maybe something like that yes of course it might but you could go in and modify those very easily within a few minutes you have your quarter model this concludes tutorial two I'll see in the third one foreign
