I’ve been using other architectural packages for modeling and would love to use Archipack. It has many easy to use features.
But have a problem with how it displays units, especially for US. When I record dimensions of a room, I either will record in total inches, or feet and inches. Never in feet and decimal feet. Decimals work perfectly for metric and Blender units of course, but the US is still using Imperial and decimal feet are a hassle to compute for every dimension.
Blender allows for checking the Separate Units to separate feet and inches but it works only for display in each Wall Part, but not in the 3D view which remains in decimal.
Units are also not consistently displayed. Sometimes rounded off, sometimes not.
I also want to second the person who asked for some US default windows. We also could use default US standard doors, walls, etc.
