Up to Face for Datum planes is fixed with: https://github.com/FreeCAD/FreeCAD/commit/fe2660b4684b51100ccc19c7479d08f7ae507398

Unfortunately, there is a limitation that the datum plane has to be parallel to the sketch plane. If the datum plane is not parallel, this error message pops up:
[quote]Pad: Extruding up to a face is only possible if the sketch plane is parallel to it[/quote]
This appears like a bug, because if there is a solid created first, then a new pad "up to face" works with a slanted datum plane.

In the attached file FC_issue3177_Pad_up_to_face_datum_plane_nc1.fcstd, padding the Body's Sketch up to the slanted datum plane produces the aforementioned error.

But Body001 shows that a sketch attached to an existing pad can be padded to the same datum plane with no such error message.

Setting target version to 0.18 to remove the restriction on plane parallel to sketch plane.

Restriction on parallel datum plane was removed by commit [ffd980b27e](https://github.com/FreeCAD/FreeCAD/commit/ffd980b27ecd155b15de07a45907608ae9062f87).

As for the rest of the request, I'm not sure. The request asks for "up to edge/vertex". How would that work exactly? How would the pad operation know how to define the ending face, if only a vertex or an edge is selected?

In a commercial CAD I'm familiar with, you can define the extrusion distance with a vertex selected in the 3D view. But it is a different option from the "up to face/plane" option. In this case, the pad ending face is parallel with the sketch plane. Otherwise, the tool does not allow to use an edge.

EDIT: OK I just realized that the request is for multiple vertices and edges.
