Feature Request: Substractive Revolution.

[jruiz]

Suppose a sketcth S is made on a face of certain body B , then the revolution of S, say R , is made so that R be into B.
Wouldn't it be nice to have a tool for getting the "pocket" P resulting from P = B -R?

Doesn't Groove do it?

Exactly.
For some unknown reason, groove was not working in my freecad, but now it is.
How could I delete my question?

Don't worry, it will just get buried with time, rather quickly actually.
You can edit the title to insert [Solved] or something, by editing the first post.

Thanks a lot.
By the way, in the FC version I am using, groove does not appear automatically when selecting it (as it does when, for example, revolution is applied) The axis has to be (re)selected for groove to take place. Is it a micro bug?

Maybe. Please post a step-by-step guide to reproduce, then. Preferably, just a file, where one can click "Groove" and observe the lack of one.

1. Create a body,
2. Sketch a rectangle.
3. Pad the sketch.
4. Select a face of the pad make a second sketch on it: a vertical straight segment with a arc forming a "D"
5. Place the segment on the vertical axis.
6. Close the sketch.
7. On task tab, select Groove.

Following these steps I get just a circle on the face of the sketch until I pres on (Axis) "Vertical sketch axis" and select any of the options, including "Vertical sketch axis", from here the groove is shown.

I had seen similar even with recent 0.19 but it was no bother because usually I just select different axis anyway and confirm.

DeepSOIC asked for a file, although the step by step description is not difficult. Please consider that everyone who wants to take part in the discussion has to go through it, which is in fact a waste of time, so I attach my file here.

- load file
- select Sketch001
- click the groove icon

Here it works well, the screenshot was made directly after the click on the groove tool. Please retry with a current 0.19 version. Since new versions contain not only new things but also many bug fixes. You should always check if the bug is already removed in the current version.

4. Select an axis or press Ok and then the groove will appear.
