You really need to look at the details of your objects. Select the arc and what it says in Properties

Geometry:
Valid curve.
Closed polycurve with 2 curve segments.
Segment 1:
Arc
start = (-110,0,100)
end = (-1.42109e-14,0,210)
center = (-2.13163e-14,0,100)
radius = 110
angle = 90 degrees
Segment 2:
Arc
start = (-2.84217e-14,0,210)
end = (-110,0,100)
center = (7.10543e-15,0,100)
radius = 110
angle = 90 degrees

What you have is two “near-duplicate” curves that are on top of each other and joined to each other to produce a closed curve. You can’t join that to anything else.

On top of that the line is actually two segments on top of each other, so you need to explode that and remove the extra segment.

Explode both, delete one of the arcs and the spurious line segment and then it will join.

I guess you know Jen at https://3dtraining.ch/ ?

Yep. As far as I know, no longer with the company though.

there is a command for locating stuff like this (assuming it’s not already joined, if so explode 1st)

seldup

Yeah, unfortunately, in this case the arc segments are not exact dupes so SelDup does not select them…
