Change the color in the View properties.
In 0.22 change the ShapeAppearance.

It is not possible to attach the section of a helix to the helix, whit produces. That would be a cyclic dependency.
You can do this with a Part helix or a shapebinder thereof before sweeping it.

If you have the file: It would still be interesting to know, where the problem was.

Exactly. And beyond this,
- from what I see, it works allright: both sketches have the same coordinate system before and after the merge;
- if you want to show us something, reduce the FreeCAD file to the bare minimum, I can't imagine that these two sketches need 1.9MB.

Isn't now the time for discussions?

3-dimensionale B-Splines gibt es in der Draft workbench. Leichter zu handhaben sind aber oft Schnittkurven von orthogonal liegenden 2D-Kurven. Das ist auch als "Wilfrieds Trick" bekannt.

Na ja, dafür hast Du ja noch weitere sinnvolle Änderungen gemacht, z.B. alles in einen Body gepackt.

Ich gehe davon aus das dies aus ein Teil gebaut/gedruckt wird.

Wenn es das ist, was der Dateiname sagt, dann würde ich es eher nicht drucken...

The newly created object has a depth which goes into the object where it is projected on. Make a boolean cut to get it "pocketed".

In diesem Fall solltest Du den ungewünschten Teil zu Konstruktionsgeometrie machen und dann das Teil in der Part-Workbench extrudieren.

I use the part cube all the time. Not in real models, but for quick checks to validate some answers to user questions. I even have it integrated in the toolbars for CAM and TechDraw.
