Since then I admit we have concentrated on a variety of issues which needed to be fixed and/or enhanced. It did solve some problems but in all modesty it wasn’t the solution. We from BricsCad have worked on it a year ago. The result is that Intellicad, despite advertising to the contrary, is no longer digitizer enabled. It's reasonable speculation that the developers of that product designed for all the features of that standard. The original tablet interface was developed at a time when Wintab 1.1 was the industry standard. Some of what I've seen leads me to speculate that, perhaps, no one developer owns all of the rights to Wintab 1.1.Now back to Intellicad. It's unclear to me whether Virtual Tablet implements all of the features of Wintab 1.1 either. So all of the tablet manufacturers who used their driver have had to revise their offering and all application programs that depend on Wintab 1.1 are now obsolete. LCS lost a patent infringement lawsuit to the developer of Virtual Tablet and, as a result of a settlement has declined to license or distribute their implementation of WinTab any more. Then disaster happened and destroyed the standard. Wintab went from 1.0 to 1.1 and - I believe 1.2. LCS promoted Wintab as an industry standard, and so it was. Wintab was developed by LCS/Telegraphics who wrote the drivers for Wacom, GTCO and a bunch of others. The simple factual errors in the help file remain the same.So, stepping aside for a while, let's go back to Wintab. The results are that the tablet code have not been improved and are now seven years old. But then Visio folded up and sold out to MS. I guess everybody thought they'd get it right in their next effort. That implementation was, being chairitable, anemic - and subject to a lot more criticism. In fairly short order, Visio added tablet support - in Revision 'D' if I remember right. A glaring fault of that product was abscence of tablet support. Intellicad came to life under the Visio banner using the Intellicad 98 moniker. The following is all that I've been able to find out - and surmise. I see that you're heading down the path I've stumbled down before.
