2D metaball like connection between distort forms

@DavidRutten, it seems quite simple to solve that with a good offset. As usual Polyline Offsetclipper is used (Edit it works with Rhino)

We need to talk about Offset

Dear Rhino/Grasshopper developers thanks for Rhino 6, many useful improvements, render, Rhinocommon functions … but there is an old subject Polyline Offset see this thread : Are there some news about Polyline offset ? I know Clipper is a good solution for Grasshopper and Rhino. Update : @pascal it is not a Grasshopper question more a Rhino core function. There is a reliability problem with offset Polyline. It doesn’t work on some the cells which are simple polygon (see the picture). The sa…

The trick here is to group well circles in branches. So @Edward I didn’t reuse your script. The second trick is to offset in one direction then in the other. By default Clipper is doing the 2 ways. It is very important to have grouped curves in one branches. If not Clipper will merge offseted curves.

I was a bit negative it works with Rhino offset.
