Angled roofs

It's quite easily actually. all you need to do is make the two roofs like you would normally, so you end up with something like:



From the underside:



Then what you do is you select them both, and run the clipping tool down the seam where they join:



Then all you do is select these two parts:



And hit delete! Voila!

It gets a bit trickier if the roofs are two different sizes, though it's possible if you line them up correctly. This works for non-90 degree bends too.

Are you talking about a two roofs that meet together to form an L shape?

First roof that came to mind would be this one from koth_harvest: http://www.tfportal.de/gfx/content/tf2/maps/koth_Harvest.png

What I would do is create an angled brush, duplicate it, and rotate it the desired amount.


Then I would use the clipping tool (located on the left toolbar or just use the shortcut Shift+X) and clip each brush so they'll line up. I think most people here would suggest using a 1:1 or 1:2 slope, it's just easier to work with in the long run.


Finally, just drag the two together until they line up and voilà, you have your roof!


Hopefully this was the answer you're looking for. If not, perhaps it would help to get a couple better screenshots of what you're wanting. I'd suggest starting up a local game in TF2 and then typing the following commands in the developer console: sv_cheats 1, noclip, r_drawviewmodels 0, and cl_drawhud 0. That ought to give you the ability to fly around and take screenshots without anything getting in the way.

Edit: Alllllllllly

Personally I'd go for vertex manipulation. Put the brushes next to each other so that they touch on the inner corner and then just move the outer corners to the correct spot.

Clipping doesn't require you to find the correct spot, just split them on a 45 and you're done.

For a 90° angle I would do it like Aly.

For any other angle, I would place the 2 brushes in a way like this:


Then I vertex edit the vertecies by only using the arrow keys. I first start with a pretty high grid and go down untill it's at 1. As the vertecies of the rotated brush are not on the grid, I now select all these vertecies and press Ctrl+B. What I end up with is this:


Now i also use Alt+P to make sure that I didn't make anything invalid.

The End
