Hello!
I've beend using D-Tools for approximately one year now. We are currently upgrading from Si4 to Si5 (once the current projects are finished).
We use Visio which seems to be enough for what we do. However importing CAD files has caused a few dramas... typically due to old versions of AutoCAD being used or "special" CAD programs that aren't true CAD files
I'm currently looking into what training is available to further my expertise. Are there live webinars available? I know it would mean a late night but more beneficial than a pre-recorded lesson.
