Measure length of point on polyline from start point

[Anonymous]

I would like to find the length of a polyline from the start point of the polyline to a point on the polyline picked by the user.

I had a program that worked fine in Autocad 2002 which used the Curve.cls v1.3 and VLAX.CLS v1.4 from acadx.com. Now in Autocad 2006 my program does not work.

I could post code if that helps.

In the VLAX.cls change the line that reads VL.APPLICATION.1
to VL.APPLICATION.16

Wow. That is fixed everything. Thank you so much!

I understand the rest of my code except for those two modules listed above. I would appreciate it if you could provide a short explanation of why that worked. If not thank you anyway for your time in providing a solution.

The VL application is the VisualLisp API provided by Autodesk. In Acad
R2000-2002 the actual version is 15.* but the VL version was 1, in Acad
2004-2006 the VL was changed to 16 so that it matched the Acad version it
was to be used with. Acad2007 is version 17.0 but, oddly, they left VL at
16.....

You're welcome!

You have working code that does that!!! Could you post it? That is exactly what I am needing to do.

Thanks,
George.

I'll second that, if you could post the code that would be great.

Ok, It's kind of rough but it works. Main procedure is in Macros module. There are some constants you can define at the beginning of that module.

The procedure prints to command line. See commented lines in procedure to add text at point or assign value to attribute.

Let me know if you need any more explanation or have suggestions.
