We've seen how the Tape Measure tool can measure distances but we also need to measure angles as well and this is where the protractor tool comes in handy. You can find it under tools>Protractor or here in the toolbox it's called the Protractor tool and it looks exactly like a little protractor. And when you select it, this icon comes up and notice how when I drag it over any face it snaps to being parallel to that phase, it's almost like the Rotate tool and how works in that way.
So if I want I can use this to create guides to draw anything I want. So let's just do a real quick one here, I can just go ahead and select here. So what you have to do is click once, drag out a line, click a second time and this is where you set your angle and you can see your angle down here in the box in the bottom right-hand corner, and then you click Again, and it creates a guide at that angle. Now I am going to go ahead and select this and undo and let's go ahead and do something that's a little more specific.
I want to put a roof on this house. So let's go ahead and start here and build a roof. Now in order to do that I do need to create a line from here to here so I have a full extension here in order to extend the roof. So I am going to go ahead and draw that line in and now let's go ahead and lay in our guidelines. So for a roof you want to know exactly what the pitch of the roof is and you need to convert that to degrees. For this roof I am going to use an 8, 12 pitch and my little chart tells me that that's 33.75 degrees.
So I am going to go ahead and snap to the corner of this building and drag out my angle. Now I need to type in the number I know that's the pitch of my roof 33.75 degrees and hit enter and now it creates a guideline with that angle. Let's do this Again, on the opposite side so I am going to snap make sure its green, if you hold down the Shift key it will force it to remember that inference, and then I am going to go to the endpoint on the opposite side of the roof, left-click, drag, click and then drag Again, to set that angle and Again, I am just going to type in the number 33.75.
Now once I have that I have the guidelines I need to build the gable and roof. So its go-ahead and click on the endpoint, click on the intersection and click on the endpoint again. So there I have got to start at my roof and then all I have to do is hit the Push Pull toll and pull that out and make sure that that is 30 feet, so I am going to type in 30 feet because that's I know how wide my building is. Okay that's a very simple roof, but let's go ahead and go further with this and make this roof a little bit more complex, Obviously, we need a roof over this extension here.
So let's go ahead and put another roof on this, in this case we are going to snap to red, so I want to make sure that I'm on red, so you can just click their, so click once click twice, sweep out the angle and Again, same roof pitch 33.75 and do right here click, click, drag 33.75 okay. So now I have what I need to create this end of the roof so Again, just select my line tool draw it out, in case that's the end.
Now if I wanted to I could use a Push Pull tool, but what that's going to do here, let me show you why I don't want to use that. What it does is it actually intersects in a way that I don't want it to intersect because what I am doing is I am pushing this geometry through the other geometry, I don't want that, I really want this to be a clean line, all I need to do here is just draw a line. So I can just select my line tool, draw make sure I'm snapping to the red axis and then when you get to the front face of that roof it will tell you it's on the face so I am snapping to the red axis, and then I snapped to the face, click the second time and that's the peak of my roof, so then I just take my Line tool connect that and that, select my Line tool Again, connect that and that.
And now I have pretty decent roof. So if I want I can go ahead and erase these guidelines. Now I want I can also go further let's say instead of this Gable and roof we wanted a hip roof. Well we can do that as well and we can use construction lines to help us with that as well. But the first thing I want to do is just go ahead and select my Line tool, and then I want to infer parallel to that edge and click. So I know that this is 33.75 I also know that this is the same.
So once I have that I can go to the top of the roof, click here and what I've done is have actually created a face underneath here, if I view this in x-ray mode you'll see that I've actually created a third invisible face here. So all we have to do to see that it is just select and delete these outside faces and then this roof will come up. So I am going to go ahead and turn off x-ray mode and you can see how now I've got a nice roof line that actually lines up with that front part of a roof.
Now we can do the same on the other side if we want a hip roof, its going to be a little bit of a different process, but let's go ahead and go through this because a lot of people do want to create things like hip roofs. So Again, I need to sweep out the angle that represents the pitch of my roofs so I want to make sure I snap to red in this case, click, click Again, and sweep and Again, I want to do 33.75 and that gives me the angle from here, but Again, this roof is slope so I would have no idea how to translate this angle onto that roof.
So let me show you a little trick with the line tool here. If I click here and start going up you'll see that it infers to the top of the roof right here. So once I do that I know I am at the height that that roof is. So if I click there, I know that the top of this is the same height as the roof, so if I go straight over now I have a line here that will represent that same pitch. So once I do that I get this extra geometry, but I can certainly delete that, all I have do is just delete all that, and then I have a line here which represents the pitch of the roof that I want.
So all I have to do is connect that and Again, I have created that same invisible face that I created before. So all I have to do is just delete those with erase tool or by selecting and deleting. And let's go ahead and delete my guideline and this line as well and that line. So now I've got pretty nice little hip roof there. And I did it using the Protractor tool. I'm sure you can use this tool along with the tape measure tool to create very precise models.
