@HarryGeier: I don't want to clutter any forum with useless chatter, but I have to thank you for your responses.

@HarryGeier: Thank you so much for your suggestions! I had already tried your first method, but it failed on me because—now I know!—I used an improper radius value... A couple of questions: In your first method, how can the radius of the final (reduced-radius) surface be calculated? (It may be a dum...

I would like to extend this discussion. What if you want to taper , which is the opposite of countersinking in a way? Take, for example the pins shown here: https://www.mill-max.com/assets/pdfs/224.pdf. The one on the upper left can be easily generated by stacking and positioning cylinders. Is there...

Thanks a lot for the tip, Willem. In my case, I needed to find the cross section of a shell in the shape of pyramid, which was not a solid. Your recipe worked with the shell, too!

I want to specify precisely the position of the plane where the cross section of an object will be taken. I can determine the plane with the Draft Workbench's working plane, so FreeCAD can determine the plane I want. So, then, the question becomes how to transfer the position data from the selected ...

It seems this issue has just been fixed! The latest version of FC17 (see below) finds the snap points in a file in which it had been failing up to now. Congratulations and thanks to everybody for their hard and dedicated work! Here is the version of FC I just installed, which fixes this issue: OS: U...

It seems that with the latest FC update (see below), the memory leak is gone. Draft snapping on the same objects that caused the memory footprint to expand by several GB causes no perceptible (as far as 'top' is concerned) increase in the memory footprint. Also, FC snaps instantly (vs. "thinking" in...

Yes I also think there is something else... I'm trying to reduce the code until there is no memory raise at all, but that's really difficult to assess... From brief experiments on my end, I have found out that the GB-size memory leak happens when I try to use snapping on a particular object (part o...

If your using the freecad-daily PPA it should pull in the standard Ubuntu package. 2.7.11-1 or 2.7.11-2 should not be reported as 2.7.12 in "About FreeCAD". Any chance at some point you added a Python2 PPA to your software sources? I hear you. I looked through my '/etc/apt/' directory and I did not...

Where is Python from? https://packages.ubuntu.com/xenial/python That's an excellent question! I don't know how to answer it. I have the Anaconda virtual environment installed for my Python needs, but there I have only Python3. Yes, Ubuntu states 2.7.11- 1 as their official version, not the 2.7.11-2...
