getPointAtDist() to return a NON-Vertex point on the Polyline...

[Anonymous]

Hey guys,

I need to get the coordinates of a point on my polyline, which is at a specific distance from the start point of my polyline. When I use the getPointAtDist() function, it returns the closest vertex to that point which is apparently not what I want. Is there something wrong or is this function supposed to only return vertices?? I mean what if my distance does not have a vertex at??

If it is so I think I could add a vertex to my polyline by means of PEDIT command, but the problem to that is I can't give it a distance on the curve 😞

If you guys could please provide me a solution, I'd really really appreciate it 😞

I just looked at the code for 2d, 3d, and lightweight polylines and they are
all coded to return points between vertices if that's where the distance
specifies. I don't know what's going on in your case to cause only vertex
points to be returned.

Hi,

Thank you very very much for your response and your effort. In fact you made me realize that the getPointAtDist functions, work as I expected they would. So I found out there was something wrong with my code. As far as I was using the point to draw a line, with the LINE command, I realized that it is obeying the OSNAP settings!, so it would snap the point at the nearest vertex. Instead I added the line to the database through an AcDbLine object, and it works now!

Thank you very very very much again Mr. Cooney.
