PTExport.LSP almost works.

[ibSteveB]

I have a single PolyLine with line segments, arc segments and sometimes spline segments.  I am trying to get an interpolation of the points along the PLine exported to csv or plain txt file.  PTExport.LSP does part of what I want to accomplish; It gets the start and end point of any segment.  What I am looking for is an export of each point along the Y axis going up from origin by specific step like mm or 1000th inch.  Preference is mm resolution.

 

Is there lisp or other macro up to the task?

 

Thanks...........Steve

So looking at first segment in sample dwg.

From point:  X=   460.7424  Y=   44.9150  Z=   0.0000
     To point:  X=   400.4174  Y=   28.8283  Z=   0.0000

 

Y diff = 16.0867 so if we used 1 as step size would get 15 extra points in the Y direction is that what you want ? Its a lot of points if we go less than 1. Something like 950+ points at a step of 1.
