Dreiarmiger Halter polar pattering after fillet - Setting ?

[Autoguider]

Dear Florian,
I refer to https://www.youtube.com/watch?v=qJG_31_Msxw
I am running 0.19 Rev 24267 +99 (Git) on win 10 Vers. 2009
After applying the filleting to the pocket the polar pattering does not work. Without the fillet polar pattering works well.
When setting the fillet's property Support Tra... to true the pattering works.
It is the 3rd item in the property list under Basis.
I have no clue what this property does and could not find it in the documentation. The hint text is not meaningful to me. What is a dressed part?

It would be great if you make some advice in the video on setting of this parameter.

Many thanks for your tutorials that give me a good chance to enter the 3D CAD- world.

kind regards
Christian

If not, then I will have to look a little bit deeper.
