You should use PartDesign_Hole for a counterbore : https://forum.freecadweb.org/viewtopic. ... 28#p618124

If I move the rectangle near the origin, no problem to move the rectangle.

(select a vertex, Z,O (=Sketcher_SelectOrigin), C (= Sketcher_ConstrainCoincident)
(suppress this coincidence)

* Show only the 1st pad
* Show/hide a DatumDlane (to see the face to use)
* Change its support : '...' -> Clear -> Select face -> OK
(* move it upstream in the construction tree : PartDesign_MoveFeatureInTree)

You should create you DatumPlane on the first face possible.

No error for me but very slow.

You should use more often PartDesign_Revolution and perhaps PartDesign_WizardShaft
AP-04-018 is nearly symmetric ?

I was speaking of a sketch with visibility problem.
I see only a sketch with bad pratice.

If the ShapeString was inside a body with MapMode and Support, you can set Map Reversed to True.

Suppress the body ! Don't know what is the problem.

You should do more simple sketches if you have problem reading them.
Can you provide an example ?
