a point on a polyline at a specified distance

[kedhas]

I'm having a trouble in locating a point on a polyline at a specified distance from the begining of the polyline in VBA application which I'm developing.
Can any one give me a clue?

To solve the distance on a pline you can build a 2D array containing the infomation of length, starting/ending points' coordinates, center coordinates, buldge etc. for each segment in the pline. And, the 2D array variable should be made public variable. I call it SegArray().
The attached is the my trail version. It can measure the length along a pline between any two given points. Bugs may occur when analyzing a curve. However, this program shows one option to solve the problem.

Good luck.

Hi kedhas,

It requires calls to lisp, but if you search Google for "vlax curve
class" you will find an easy to use set of tools which not only give a
one line solution to your question, but lots of other functionality as well.
