But I tried to ask in a way that would make it look like I thought I was doing something wrong, which is usually the case. But as usual, Alfred is on to me. Surface dimension tool with a bend would be perfect. I think I posted this topic a few years ago and it got flicked away. It's not something I need all the time so I'll just continue my little 'workaround'. Unless there was a big demand for it I wouldn't expect a new tool. _________________ Ed Jaworski 20" imac 2.66 dually OS10.5.5 PCadd 8.07 Wild Tools 9.something www.schroederiron.com

There are two ways I know of that arc length dimensions are drawn. The first is with the witness lines drawn parallel to each other like a face dimension and the other is with the witness lines perpendicular to the ends of the arc, like an angle dimension. The figure attached shows these. Personally, I like the option on the left because it is less ambiguous when the object being dimensioned has thickness. If you look at the drawing on the right, how do you know which length is being dimensioned. Is it the outer surface, the centre line or the inner surface? The other customary things that define an arc length dimension are the curved dimension line and a small arc which is placed over the dimension text. Both these are common practice. Again, I think the left option jumps out as something different and makes it less likely to be mistaken as an angle dimension. The right version could easily be mistaken as representing 30°. What does everyone else think?

Also, I prefer arrows to the slash. _________________ Mac Pro, 9 Gig RAM, OSX 10.5.4 Pcadd v8.0.2

Surveys often have such information. The only place I've seen an arc length shown is on the wildtool arc extension tool...which was partially developed to aid in redrawing surveys for site plans. So somewhere the technology exists...inside an existing tool. Why not at least report the information on other arc/radius tools? And it does report in feet in inches. _________________ Peter Carlsen
