davidstvz Posted June 18, 2020 Share Posted June 18, 2020 I've attached my plan. I have auto-rebuild roofs enabled, but if I try moving any exterior wall, the roof doesn't rebuild. Furthermore, if I delete the roof and manually select build roof (with or without auto-rebuild), it rebuilds the same roof that was deleted. I can manually edit roof planes, but I'm really relying on starting from an auto-roof. Does anyone know what's going on or how to fix it? Hopefully I've just missed something obvious. Oakborne_Lot_31_Y_(house_18)_broken_roof.plan EDIT: I've partially solved the problem. When using auto-rebuild, the option for "re-use existing roof baselines" can't be toggled. I unchecked auto-rebuild and disabled "re-use existing roof baselines" and the new roof covered new portions of the house as it should, taking into account changes in the walls. So if I manually rebuild the roof, I can make it work now. However, I'm unable to make auto-roofs work properly. It seems auto-roof insists on reusing an old roof base line.

solver Posted June 18, 2020 Share Posted June 18, 2020 Do not check Make Roof Baseline Polylines unless you understand what that does. Go to Edit>Delete Objects, select Roof Baseline Polylines and delete them. 1 Link to comment Share on other sites More sharing options...
davidstvz Posted June 18, 2020 Author Share Posted June 18, 2020 Thank you, that was very much the problem. I was experimenting and tried that somewhere along the way. Link to comment Share on other sites More sharing options...
