If you use the method to constrain a screw, on a reference or circular edge.
Normally it works?

Hello. This works perfectly with " prisms ". I admit that I rarely use for prisms, rather with concentricities (bores in plates and guide columns in these bores) but the principle remains the same. Define 2 faces (always the same, make your own " standard "), choose " opposite direction" on the female for example and " same " direction on the male. Don't forget to name the constraint reference. If you have several T-slots (or dovetails) on your chassis, you need to create as many stress refs as there are associated shapes on your part. If it doesn't work at home, then check your settings (I'm on SW2023 sp5)
