Convert Curve issue

Rhino Rhino for Windows

Hello,

I have tried to simplify one closed curve by converting it to polyline with the command ‘Convert’

‘Convert’ does the job but it also chamfers some straight 90 deg corners !?

it happens when I set the Convert parameter minLength > 0

for testing, attached file contains two overlapped curves - “original” and “converted”

Hi Aleksander - at these settings it seemed to do what I expected:

Output=Lines SimplifyInput=Yes DeleteInput=Yes AngleTolerance=20 Tolerance=0.25 MinLength=0 MaxLength=0 OutputLayer=Input

The only thing to watch is that the curve seam is on a straight segment so that segment is not simplified fully - use the CrvSeam command to move the seam to a corner before converting.

Thanks for your prompt reply.

I have few questions about the parameters for the ‘Convert’ command

“Angle Tolerance” :
how to understand the value “20”? - I thought it was in radians.

“MinLength” :
I intended to use “MinLength” to make sure there are no short segments because contour is to be used for cutting, where short segments are not recommended… - how can make use of it?

thanks in advance
