Did you try with AutoCAD 2013? The full, regular version? Do earlier AutoCAD versions also work with touch OS Win 8?

Ralph Grabowski

I tested the touchscreen/Win8 combo with AutoCAD 2013. I don't expect that earlier versions would be any different.

After all, Windows 8 is just a Dr-Jeckle Windows 7 with a partial Mr-Hyde UI makeover. For instance, BricsCAD runs fine on Windows 8; haven't tested any others, yet.


Ralph: Your experience doesn't surprise me. Holding up your arm to point at and touch a screen positioned like a traditional monitor just won't cut it. And your "fat finger" experience makes obvious the fact that current UI paradigms will have to change for touch. Now imagine a touch screen configured more like an old-school drawing board and we might be getting somewhere.

SpaceClaim claim that last year they rewrote their software to be touch-friendly. They also noted that the monitor had to be laying down to be effective.

It must have not been all that successful, for this year they aren't pushing touch. Reminds me of think3 did the same thing with voice input: flattened the command structure to accommodate voice commands in one release, and then ignored the feature in the following releases.

I would like to comment on your mention of how the "fat-finger" syndrome doesn't produce enough accuracy for design work.
I don't think this is new to touch-screen CAD at all. I'm sure that during my life I have worked on/worked with/repaired a great many products that were designed by people with "fat fingers", like the burned-out car dash light bulb that can't be replaced without removing the entire instrument cluster, or certain Porsche and Chevrolet models that required removing the engine to replace the last spark plug, or the '37 Rolls-Royce that required drilling a factory-prescribed hole in a chassis cross-member in order to remove the last bolt holding the starter motor. or the leaky condensation tray on the refrigerator that can't even be patched without removing the motor/compressor and hence the refrigerant, or....

My pet peeve: It seems to me that freeway interchanges are designed more poorly as CAD is more used (cf. 200th street interchange on Hwy 1, as well as the double-traffic circle with nine roads at the McCallum interchange here in Abbotsford).

Smiled when I saw your comment about freeway design Ralph. Remined me of a bus interchange built for a local high school. I provided the designers with the minimum turning radius required by our buses (I was designing them at that point in time). The very first day the buses very nearly ran over the toes of students as they mounted the footpath when entering the interchange. A complaint was made to me and when I went to inspect I found 90 degree left turns (buses entering and leaving) with no radii and the required radii plus a bit on the right hand turns made within the interchange.
I found the designers did not KNOW? a bus needs the same turning radius for left and right turns. Dumb, I know, but real and, CAD would not have made any difference in this case.
Please note!. I am talking about a country where we drive on the correct side of the road ;-) meaning we pass starboard to starboard so as to facilitate the drawing of swords to engage an on-coming opponent.
