I don't know if autocad supports OLE. If it does you'd obviously need
autocad on the machine you were editing on just as you require Word on the
machine when you editembedded Word docs.
You certainly will not do this by writing code and using Windows Forms
objects without about 100000 hours of pretty intense coding on your part.
I know that Autocad should install on that machine.
But I think my work is easy and my application want to open it and edit it
with autocad.
I think if Autocad supports OLE it's not hard.
