This article details how to finish a roof elevation by adding it to a front view using various tools and techniques. It explains the step-by-step procedure, from building the roof from scratch or starting with what's known, to adding the roof, creating a new turning line, and finally adding all the roof geometry for elevations.
Key Insights:
- The article provides a detailed process of finishing a roof in elevation by adding it to the front view. This can be done either by building the roof from scratch or starting with an existing roof.
- The process involves various techniques such as projecting lines across, using the shift right click mid between two points, and using mirror lines to add the roof on the side. The article also emphasizes the importance of adding the longer overhang and creating new turning lines for more accurate results.
- Beyond the roof, the article also touches on the use of match properties tool to migrate geometry across layers and the process of blocking out and creating doors and windows, suggesting that these tasks will be discussed in further detail in subsequent articles.

In this video we are going to finish our roof in elevation by adding it to our front view. Now we have a couple of opportunities here.
We can either build this roof from scratch, just like we did this one, by going to our front and right views and projecting lines across. Or we can start with what we know, which is this roof right here. This roof is going to match this roof right here because they are the equal overhang on both sides.
Let's do that to begin. In this case I'm not going to draw my line, instead I'll use the shift right click mid between two points. Okay so let's go.
I'll do mirror. I can come down here and with a selection window grab these lines. You'll see that I have found five objects.
I'll hit ENTER to lock it in. The first point of my mirror line will be the shift right click mid between two points of the end point of my top of plate here and the end point of my top of plate here. I need to zoom way out, drag way to the left with ortho on and click.

Do I want to erase my source objects and enter? And there we go. We've added the roof on this side. But before we forget, let's go in and make sure that we add this longer overhang which will come down lower on our drawing.
So I'll go to the view tab and I'll change this to my front view. Control S to save. Okay, now we need to bring over this lower datum.
You can see we can do that by this point or this point. It's the same data. But before we do that, we need to create a new turning line.
The turning line could be mirrored if you've set your drawing up exactly, but I'd caution against doing that. When possible, always draw new turning lines. Let's go back to the home tab.
A no plot should be our current layer for the turning line. And let's add these lines. Now with ortho on, I don't need to use construction geometry, as in X lines.
But I can use simple lines. I'll go line this end point. And notice I only need to get past this datum, so out here should be good.
Make sure you have ortho on for this. Click, enter to say I'm done, enter to go back in. Next I'll choose this end point.
Out to the left, roughly the same distance, and click, enter to say I'm done. Enter to go back in, this end point down. Make sure you go through your lines.
Click, enter to say I'm done, enter to go back in. And one more time, this line down through the lines. Click, enter to say I'm done.
Now we can draw our diagonal line. Enter to go back in, this intersection. I'll turn off ortho.
And I'll go to this shift right click intersection. Enter to say that I'm done. Now I can delete this geometry and make this line just a little bit longer.
I'll pick the line, click the grip to make it hot, right click scale, three, enter. Escape, escape, escape, control s to save. All right, now we can bring down this geometry and turn it to go to this view.
So I will use construction lines here. Construction line, v, enter. I'll pick this datum and this datum.
Enter to say I'm done. Enter to go back in, h, enter for horizontal, picking this intersection and this intersection. Enter to say I'm done.
Now in this case, we did not switch our current layer to a heavy. So let's delete these two lines. And let's migrate this data to the a heavy layer.
In order to do that, I could select the geometry and pick a heavy. But instead, I want to introduce the match properties tool. The match properties tool is right here.
And what it does is it selects some source geometry. And then any geometry you click on next will match as many properties as possible. Specifically, layer, color, line weight, and line type are the ones we focus on most often.
So I'll go match properties, pick this yellow line, and then pick both of these lines. Click and click, enter to say that I'm done. Now that geometry has migrated to the a heavy layer, not just changing color or line type, but it actually moves from layer to layer.
Next, I want to make the a heavy layer my current layer because I forgot to switch it. Here is the make current tool. So instead of grabbing my dropdown, I can grab the make current option and then simply click on an object on the layer I want to make current.
There we go. Now a heavy is our current layer. OK, we need one more piece of geometry.
If we look at our roof plan, we can see that the overhang that goes extra long is on this side. So I need to bring down a datum from this point because we don't have that anywhere in this drawing. So I'll go draw construction line, v enter for vertical, and I'll pick this point right here.
Enter to lock it in. Now this is a little bit of a mess, but I think we can get through it. The first thing I want to do is to connect this roof to our lower datums, OK? This is a fillet from here to here.
Enter to go back in from here to here. Now we want to turn those two lines, the bottom two lines, up at this midline. So fillet again, top of the bottom two.
So it's the third line down to this line. Go back in with Enter, bottom line to here. OK, so now we've turned the bottom, but these two lines are still too long.
These need to connect to this line as well. Fillet one more time. This time I'm going to zoom way in, choose here, which is the bottom of the vertical line, to this line on the right.
Enter to go back in. Again, I'll choose that bottom, and then I'll choose this yellow line. There we go.
Now this roof hangs lower on this side, matching the datum of this point here. And on the right side of the roof, it's higher, matching this datum, which we can see in this view. Before we forget, let's make sure to trim up our wall geometry.
So I'll go Trim, T Enter to select my cutting edges. It's going to be the bottom lines here and here. Enter to lock in my cutting edges.
And I'll choose this geometry here and this geometry here. Enter to say I'm done. Let's go View, Left, Zoom Extents, and Control-S to save.
We have now added all of the roof geometry for our elevations. In the next video, we will begin to block out and create our doors and windows. I'll see you there.
