Ok it's merged! Great start rockn!
A couple of things I noticed, probably you know about them too.
- Invariably, my roofs start the wrong way like, the roof panes go towards the outside of the building, instead of the inside. I tried changing the angles to 135° or to -45°, but then come weird results (some panes don't appear anymore). I am not sure it is intended to be able to set such angles. Is there a clear rule to obtain "correct" directions?
- If this can be a good way to solve direction problems, it might be handy to add for example a button that "rotates 90°" that would switch all angles between 45 > 135 > -45 > -135.
- Maybe specify the units in the text above (angles must be in degrees, units in mm). Another idea is to add a suffix to the numeric fields.
Other than that, very good already. Much more useful than what we had until now. Congrats!
