Curve - plane intersection

Select the plane & the surface, then go to Tools/Sketch Tools/Intersection Curve.

WT

The intersection of a surface and a non-coincident curve (or edge) is a point. You can place a point at this intersection using a datum point or a point in a 3D sketch. In a 3D sketch, you can constrain a point with on-surface to the surface and coincident to the curve.

In a case of a planar surface or a plane, you can open a sketch, create a sketch point and add a Pierce relation beetween the point and the edge.

Finally made it! Great advices, thanks!
