from spline to polyline - how to reduce the segment count?
Posted: Mon Aug 22, 2016 8:34 pm
Hi all,
my task: convert a spline derived from actual measurements on my boat (height of a coaming rim, to be the base for a new solid dodger / pilot house) to a polyline. Furtheron, the result shall be integrated into the shape of a window frame for the dodger. Frame and window are to be waterjet-cut.
The red line in the attached dxf file is a spline derived from 12 points. The green line is the result of exploding a shifted copy of that spline (factor already set down to 2). I want to reduce the number of segments that this polyline is composed of. I tried polylinesimplify with various tolerance settings - no change. Then I saw that a tool named polylinenormalize exists - but I did not find any information on its purpose and usage.
My goal is to reduce the polyline to, say, 20 or so (order of magnitude) segments. Yes, I could purge single points manually, but if there is a parametrized way - I've got some more lines to process...
Thanks in advance!
Cheers,
Ulli
