How to move a point on a sketch on to the corner of a body

Voyager

Hey, I would like to move the point of the triangle to the top of the body.


The biggest problem is, that onshape wont let me select the corner of the body, because its in a other sketch.
Could you please help me fixing this?

Press U then Q.  U is the Use tool.  Q turns on construction geometry.  Then grab that top edge.  Now you can select the corner of the body.

You can click on the points to select them and then hit [i] or the coincident constraint to line them up. You could also, while in the coincident constraint tool, select the top of that cylinder, then the point.

@Voyager, "Pierce" provides another approach for constraining sketch entities to existing geometry.  In this case you can pierce the circular edge (visible in isometric view) with the vertex of your triangle.

In other situations it can be helpful to create an "Intersection curve", or split a face of the part, to make the geometry more accessible for subsequent sketching.
