Firstly, thanks for spending time on this.
Secondly, I'll look at the different settings that you describe, but it does seem from what you are saying that I have stumbled on some serious bug issues as the whole interest I have in 2cad is the sketchup xref workflow :-) &/or architectural objects such as wall etc ! So if I understand correctly, for the moment I can't get reliable 2d drawings in 2cad from either of these input methods :-( ... Shame, as I really beleive in working in 3d & then just outputti,ng working drawings when & if needed... unless of course we can get the whole industry to adopt 3d files & give contractors 3d files to work from ! (dream on Paddy I hear you say !)
I hope you get it all sorted soon as then I would seriously consider buying this product, as I'm sure would several colleagues (all of us are looking for affordable software, adapted to smaller architecture practices - we can't all invent/afford katyia based products like Gehry !) - though some larger firms I know might dump Revit & those Autothingy people who take too much profit and do mediocre programs...
I really do believe in smaller software companies with competitive products (such as Bricscad, which I bought when I founded my company as they do a good Autocad-like at reasonable prices & they fix their bugs seriously & often !)...
Well, keep up the good work, & when you have a reliable product for my needs I'll be more than happy to promote it !
All the best,
