Yes. It was 27-28 january

1. Sorry, the file "prictice" created in version of FreeCAD 0.16. I replaced it in my previous post to "helix-BSpline" which created in v0.17. 2. When I test sweep tools, diameter of pattern in sketch for sweep is adapted to configuration of helix (BSpline), I set diameter to 0,1...

This looks like a 0.16 file migrated to 0.17, with such Body names as "Revolution001Body", "Revolution002Body". The migration process might be one of the causes of your problem. As chrisb replied, please provide the FreeCAD file. Yes, the file was migrated. I create new one 0.17...

When I use FCSpring script with several pitch (distance between spire), sweep tool call crash in two version of FreeCAD if frenet option is disable. Another configuration of helix, for example, with different diameters, work well. Program received...

Could you please check this in the current 0.17 version. 0.16 seems to projectonly one side of the fillet. Good day (or night :))!
