Lighthouse Posted December 14, 2015 Share Posted December 14, 2015 I called tech support and they said I could turn my terrain into a symbol, and then adjust the elevation. That works! I will post some pics after I finish the model. I'm trying to create a parabolic roof for a contemporary house. I can't figure out a way to do it with roof tools, but I can create a parabola using a terrain perimeter and then change the material to roofing. However, I can't figure out a way to turn the terrain into some kind of object that I could put on top of the building. It appears that you can only create one terrain perimeter per plan, so I can't use the one I created as a roof because I also need to have an actual terrain at the ground level. I've attached a sample plan just of the parabola. It is a square, with two adjacent edges at 100 elevation, and the opposite corner at 200, which creates the dish. Can anyone think of a way to use the terrain perimeter as a roof, or is there any other way in CA to create a dished surface? I need to create about 6 different roof shapes this way on the same plan.

Joe_Carrick Posted December 14, 2015 Share Posted December 14, 2015 David, 1. You failed to close the Plan before zipping it and attaching. 2. A pic (JPG or PDF) in this case would probably be better anyway. Link to comment Share on other sites More sharing options...

rlackore Posted December 14, 2015 Share Posted December 14, 2015 I don't think Chief has any tools (other than Terrain, apparently) that can create a ruled surface. Link to comment Share on other sites More sharing options...
