Seems like a bug to me. The output curves should not be looking so wrong. Bug with curve offset.3dm (97.8 KB) [Bug with curve offset in Rhino 7 (will be left forever unresolved)]

Due to several bugs related to the “Offset” tool, I’m forced to explode the joined curves to their separate pieces, then offset them individually, then extend them with ! _ExtendDynamic _Pause _Type=_Natural, then split them where they intersect together, then join them all again. It’s a slow and re…

I may try (and learn how do to) this out soon, because it’s a pain to work with the “Offset” tool in its current state.

Right - - if we are getting extra points in polyline, then that should be fixed in Offset. My tests did not have these but I see that on a chamfer there are extras. RH-80116 Offset polylines - extra points in the output -Pascal

Offset Loose with polyline works fine in Grasshopper. And we have Point Deform component that is useful in this case. This is a minimum effort, almost no tested, proof of concept for an offset loose that return correct curves with lines and arcs. Arcs are expected to be tangent to previous/next s…

[image] Shynn Sup: I really don’t understand why Rhino’s offset is adding extra control points to a polyline. I ran some tests, I think the bug is not in offset but in simplifycrv It’s on the list as RH-78932 SimplifyCurve does not simplify this polyline I added this thread

[image] Wim Dekeyser: They look fine in Rhino 8, which uses a completely different algorithm to offset 2D curves than Rhino 7. -wim Oh, curve offset is new in Rhino 8? But still no realtime preview during the selection of a distance in the viewport? :cry:

Do you mean the “ThroughPoint” option in the Command line?

[image] Bobi: Do you mean the “ThroughPoint” option in the Command line? I think he means that when you select the Distance option to pick a distance, you get no preview of the offset. [image]

[image] Shynn Sup: I think he means that when you select the Distance option to pick a distance, you get no preview of the offset. Dunno, I get a preview here with the distance option set… [image]
