Any way to list contraints in assembies and have each constraint list what it constrains, like in 2D? Looking at Linkages Tutorial, left link. (by Paul Raymond)
First, thank you for a remarkable program, I've been using 2d for a short while, just started using 3d, but trying to figure out assemblies.

Using Solvespace version 3.1~70bde63c.

I've been going through the Linkages tutorial to understand how the solid models are constrained. I'm having a problem easily seeing what the constraints, in the assemblies, constrains.

In opening "link-left.slvs" by itself, sketch-in-plane lists 12 constraints. If I click the first constraint, for example c001-pts-coincident, it brings up a screen which shows what it constrains, r001-#XY and r004-circle. So in 2d everythng seems nice.

In jansen-asm.slvs, if I go to group link-left, it shows four constraints, c032-pt-on-face, C033-pt-on-face, C034-pt-on-line, and C035-pt-on-line.

If I click the first constraint, c032-pt-on-face, it brings up a screen listing c032-pt-on-face, but it does not list what it constrains. Took me a bit to realize if I go into group foot, click on the front face it lists it there, as well as C033-pt-on-face, the second constraint. Why when you click constraint, it only lists the constraint, it doesn't show what it constrains like in 2d?

If I go to the 3rd constraint C034-pt-on-line that at least lists r00C-line-segment in g004-sketch-in-plane which is the skeleton. So at least that lists the other thing it constrains.

The fourth constraint in link-left is C035-pt-on-line. By deleting other groups it disappears when I delete the group called upper. I think it is constrained on a line in the upper group at a line corresponding to the pin joint at the top of the left link. By supressing the solid model in groups upper, and link-left, and showing entities for the same groups I can see the geometry. But when I click on the suspected line it doesn't list any constraints. If I delete the constraint and constrain that point against that line, I get a new C053-pt-on-line, and it appears to work as intended, but still clicking on constraint C053-pt-on-line doesn't tell me what it is constrains.

Is there some easy way to list constraints that shows what each constraint constrains, like in 2d? Maybe I'm just missing some understanding.

Thank you,
Paul
