Playhouse in CAD

I started to work on the playhouse in CAD for the first time since our old computer crashed.  I was expecting to do it on the new computer, but of course it doesn't work!  It's a 32 bit program vs a 64 bit OS thing.  Thank God our old laptop is is still running Windows Vista 32 bit, so I can run my CAD program and get to work!  Here are screenshots of the general design.  Once I figure out where the windows and doors go and the size of things, I will get into the details for how all the framing comes together.  I obviously have some interference issues with some the little awning over the door and the ladder inside. Things are still evolving...

Here's what it looks like inside:
