Strange Behavior with Collide 2D / Curve Collide

Grasshopper Kangaroo

Greetings,
I’m stumped. Seeing some strange behavior out of the solver when dragging 2D polylines in order to collide / pack them together with the mouse. For reference, I’ve internalized the 2D Convex Hulls of the referenced meshes, and for speed and user-friendliness, the idea is to use 2D collisions to orient and pack the meshes into a tight configuration.

Upon grabbing the polylines, the data gets mixed up, disappears, flickers, until release. I haven’t come across this before. I tried swapping in the newer CC component, but no luck ….

File attached to see if the issue replicates. Thanks in advance for any insight.

This can be simpler using the CurveCollide component, with the associated frames:

Excellent, thank you, Daniel! The Support goal here is great - didn’t think of that.

Have you done any work with 2D or 3D convex hull packing using K2?

edit - I just saw your post here Circle Packing + Wrap After Pack - #2 by DanielPiker which is similar to what I was thinking. The weak coincident goal is a nice way of approaching an interactive packing sequence. Great stuff as always. Thanks!
