Hi Dave,
Thank you for response - got sidetracked with work.
The program I use is TurboCAD Pro version 20. TurboCAD saves files as twc but you can within the program convert to dwg or dxf format (and many others) so you can share files etc.
The latest version for TurboCAD is version 21 so mine is not that out of date.
But when I "save as" and choose a format - dwg, it does not supply a version choice for that.
I tried attaching the TurboCAD file received the message "extension tcw not allowed". Also tried to attach the sketchup file - which sort of imported this time but not well - received the message "the file is too big, maximum allowed is 5 MiB.
But interesting this time when I tried that it did somewhat import - though minus the walls, so not really useful.
I don't know if emailing diretly to you would work better, but not sure how to do that.
Thank you for your help.
Deborah
