New LWCad User here... I've created a fairly simple building from a floor plan and added some windows to it. But, the windows I created last week only show up as holes in the walls in LW. The ones I created yesterday show up in Modeler and LW though. I don't think I created them as instances last week, but maybe did? Is there anyway to tell? A simple way to convert them to polys if I did? Also, selecting them is terribly slow (making me think either they are instances or there is some other issue with them). I've attached the object files as sometimes it's just easier if you can look for yourself. Edit: I've tried twice and no attachment seems to take :( As as side question, once windows are created, how would one go about changing the window type. I'm still figuring out which preset is which and the windows I created yesterday didn't match the ones from last week. I ended up going to a backup file and re-creating them to the same type, but maybe there is an easier way?
