Freecad 0.17 - Pad up to face - Datum Plane is invalid

Post by freecad-heini-1 »

In the German forum I asked about to create a pad out of a sketch and extrude it up to a face.
It's impossible to use a datum plane. Is it a bug, or forgotten during development, or should I ask for a feature request?

From my point of view it would be very helpful, if datum planes are allowed.

Created issue #3177. Looking for proposals for a common name for "Up to face/plane", "Up to edge/line", "Up to vertex/point".

I think you make this to complicated. up to face should be the same as up to a plane. I would think none of the other CAD Packages have dual naming...

Yes, obviously.
What I wanted to say: We need a single name for this usecase which will do any of the three variants. "Up to something" doesn't sound good. "Up to object" is still very global, so I was hoping for something intuitive and precise.

The option is named "until selected" in NX, which then prompts you to "select object." It's called "object" in Fusion 360 too. The only thing is I tend to first think of a solid rather than any kind of geometry when I see the term "object" in freecad. Maybe we can get away with not naming the geometry type:

It works for me in the following test file. I wonder if it's because the Pad feature is based on an existing solid? I'm afraid I don't have time to test further.

If I create a slanted DatumPlane in an empty Body, then create a Circle sketch and pad it with "Up to face" set to the datum plane, I get a different error than you:
Pad: Extruding up to a face is only possible if the sketch plane is parallel to it
Yet it didn't complain with my slanted datum plane in the other file! :?

If others call it object we could do so too (I know I said something different before, but I'm willing to learn :? ). Then this term could be repeated for the Button, so that the connection of the two becomes clear.
Type: "Up to selected object"
Button: "Select object"
