Flat roof without parapet walls

[marek_obajtek]

Hi,

I'm trying to build a unique roof for a utility building. I'm having trouble with the corner where the flat roof meets the wall. I tried using an extrusion roof, but the insulation thicknesses didn't match the gable walls. I'm currently using a wall with only insulation, which works for the straight sides. But I can't get the roof slope right on the other walls. How do you build these elements? Do you use a sweep?

Looks doable from here. Either by using Attach Top/Base or Edit Profile manually or a combination of the two.  Post the file so we can take a whack at it.

Thanks for getting back to me so quickly. Here is my file.

Edit: Your suggestion about Edit Profile worked very well. Those lines which are on different plane/slope do you hide with >hidden line> or attach somehow?

Create a Reference Roof that is slightly bigger than the other roof and attach the wall to that Reference Roof. Then hide the Reference Roof in the View. You can control how tall the parapets are by changing the Ref. Roof's Offset.  The Ref. Roof is created by copy/pasting aligned to same place the roof you have.

....just realized the operative word in the title. "WITHOUT" Parapet Walls. So, just copy/paste roof, enlarge, leave height alone, attach walls and hide Ref. Roof. 😉
