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

[Jee-Bee]

I think up to selection is better than up to selected object

[peterl94]

Well, if you want to use the same term for both, I would keep it short and just go with "Up to object."

it would be good to be able to define specify solids with one or both ends on datum planes. Solids such as cone, cylinder, box.

This seems to me a rather theoretic approach. Do you have a usecase for this? For me it would be enough to attach a sketch to a datum plane and pad it to the next plane.

Honestly, I don't think "object" is a good term here. Object is too generic, it can mean anything. This mode of padding is intended to go to a face or a plane, not a generic object which in FreeCAD could be a vertex, an edge, a shape etc.

If you want a more generic term, I would go with "Reference", which could be interpreted in the context of the tool. So in the Fillet parameters, a reference could be an edge or a face; in "Pad to...", it would refer to a face or a plane, etc.

[chrisb]

Any objections against "Reference"? If not I would include the notion in the bug tracker.

[jmaustpc]

"Object" is a bad idea because you pad to a specific face on an object, not the object itself.

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 have had a similar issue: Padding up to a datum plane for a sketch with no underlying solid wasn't allowed (error message regarding zero height as mentioned earlier), but padding from a sketch on the face of an existing solid did work.

However, in the case where it did work, it only half worked... I had created one item on the sketch and then duplicated as a rectangular array (see sketch.png). Only the original sketch item was padded, the others were ignored (see pad breaks with uptoface.png). If I switch from pad UpToBody to Dimension then immediately all items are padded (see pad works with dimension.png).

I see the same problem. Looks like a bug.

I'll write this up as a bug if someone tells me it's not already on the list.
