You can try this file:
ellipseprojection.FCStd
1) Create a datum point
2) Select "DatumPlane Offset Incline" as a reference
3) Select "DatumLine Ridge" as a second reference
4) Try "Proximity Point 1" as Attachment mode.
It doesn't work here either. Proximity point 1 or 2 show in report view:

Code: Select all

PositionBySupport: AttachEngine::getInertialPropsOfShape: infinite shape provided
PositionBySupport: AttachEnginePoint::calculateAttachedPlacement: proximity calculation failed.

it's strange, I've tried again the last evening and never succeed to use the proximity attachment with a line and a plane... :roll: sorry I can't understand.

I edited my post above and hope it's clearer now: It didn't succeed here either.
