What I’m trying to do is to have a whole list of curves to have multiple offsets towards the middle. Polyline Offset is a component from Clipper. This gave me the desired result visually, but not technically. Maybe there are better ways?
Initially the source curve is not segmented, this happens due to the offset.
Is your offset starting value specific in any way?
As in: does it have to be 3.899?
As you can see, offset fails after a certain distance increment - because after certain increment it’s not an offset anymore - or it is, but not a nice one - gh still tries though…but perhaps it shouldn’t give you what doesn’t work? who knows…
Maybe for this case you’re better off using scaling if it’s close enough? normal_offset.gh (26.8 KB)
The lines are smooth, however, when using this on multiple curves with graft enabled on the discontinuity and scale inputs, it generates the following geometry, which is undesired. Not all shapes have the center in the physical absolute center:
The scaling option also doesn’t get applied to a perfect circle.
It’s right before bedtime right now, I’ll dig deeper tomorrow to see if I can change your GH file to make it work more in the way that I desire. Thanks a lot for your efforts of coming up with your possible solution.
True, true, however I think in this image the issue is that the offset goes beyond a certain ‘zero point’ and it turns inside itself, moving the points further away from the center again, because there’s no space for another offset.
I wonder if there’s an option to detect if an offset has gone beyond a certain point and consequently cull that curve.
