thanks for the cooperation, it works. could also be used for other cases

You can also just redraw the wire with SnapEndpoint and use that - I'd suggest there is something fishy with its placement

This doesn't work for me if I understand correctly.

It did for me - after first aligning the workplane.

thanks, that works, there seems to be a context to where the workplane is when creating the wire

Can anybody confirm this?
No, works nicely here.

Here is my result file, one time I directly extruded the wire in Part along the direction (1, -1, 0), and the other time I added a ShapeBinder to the wire so that I can extrude it in PartDesign. The latter has the advantage that the normal direction can be determined automatically.

thanks for the cooperation. yes, these solutions are no problem for an advanced user. I'm in the process of producing exercises for beginners. my solution now looks like this ( from min 2:38 )

I can confirm the issue from OP here.
I can also confirm Uwe's observation that it works with a ShapeBinder.

yes, i've been trying to do that for some time, but in the rush it can fail from time to time. but it should be right here

But your use case is nothing for beginners. my experience is that it works best by telling that one can start with a sketch, so imagine a sheet of paper and we draw on it. This is how the sketcher WB works. When the sketch is finished, we can extrude the sketch.

Your example uses a Wire, no sketch and it is not on a "paper sheet", meaning not on the XY base plane. Sketching in inclined planes requires some FreeCAD experience. (Concept of a datum plane, concept of attachments to planes/objects etc.) You first need to introduce this and each concept requires a video to explain it and a second one that users can practice it.

my feedback to your video is therefore:
- slow down, people need time to follow you
- take time to explain WHY you do something
- focus on a single task per video. using several workbenches requires a lot of background info (concept of workbenches, introduction to every used workbench, explanations how to work across workbenches and its limitations...)

So what you do in your 5 min video requires that users worked already some hours with FreeCAD.

Side note: please encourage users to end up with technical drawings they can share with others. This will prevent some frustrations in my experience, also to my personal experience once I learned FreeCAD. Sooner or later you need to manufacture your part and then you are forced to specify tolerances. This happened for me even when I sent a STL to a 3D printing shop.
In your case you end up with a screenshot. I would omit this because this implies to beginners that this is a sufficient end of a construction.
