Last night I tried adding a breezeway and garage to a saltbox I'm working on. I created a Building Option to do this (bad idea, I now realize). So I roughed in the walls, got the offsets where I want them, tossed in a few windows and doors to be edited later. See attached jpeg of the layout.
Then I went to the second floor to add a multi-floor roof to the addition (still in the "Porch and Garage) Building Option. To my surprise, the first floor didn't show up. I tried to Overlay the first floor, and SoftPlan didn't acknowledge there even was a first floor. Then I noticed that half the exterior wall (on the right in the enclosed partial second floor plan) was gone! Notice that my reference point is at the corner of that missing wall - important? All the while, the 3D of the house looks just fine. The second floor wall was there, the porch and garage walls - just as I wanted them. I shut down the program and then restarted it. No change. I gave up and went to bed.
Now the spooky part: Today, I opened the project, and some gremlin had come in overnight and put a roof on the porch and garage in the first floor drawing! I swear I never added a roof to this Building Option! While the spook was at it, it added a first floor roof to the main house. You can see it poking out like a skirt around the house in the attached 3D.
Just this morning I read a previous post by Bill W. regarding the problems using Building Options can cause. Too late. After reading that, I decided I'd just delete everything and start over. That is certainly what I'll do!
I sure am glad I don't have to do this on the clock!
