Hi all, I'm using Freecad 0.18.1 on Debian Buster, using the regular in-distro packages from debian.org.

OS: Debian GNU/Linux 10 (buster)
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.
Build type: Release
Python version: 2.7.16rc1
Qt version: 5.11.3
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: English/UnitedStates (en_US)

The package metadata (I don't know if this is useful):

Code: Select all

$ dpkg -s freecad
Package: freecad
Status: install ok installed
Priority: optional
Section: science
Installed-Size: 51
Maintainer: Debian Science Maintainers <debian-science-maintainers@lists.alioth.debian.org>
Architecture: all
Version: 0.18.1+dfsg1-1
Replaces: freecad (<< 0.18~)
Depends: freecad-python3 | freecad-python2
Recommends: calculix-ccx, graphviz
Suggests: povray
Breaks: freecad (<< 0.18~)

In the past I've used the Path workbench for some simple 2.5d projects (cutting parts out of flat stock like plywood and aluminum plate) and it's worked really well. Now I'm trying to do a project with slightly more complicated geometry:

I used the Drill operation for the four mounting holes, two MillFace operations for the two steps in the main pocket, and a Profile_Faces operation for the three slots in the bottom. That all worked fine, but there are two remaining problems.

1. The MillFace operations avoid the cutout in the bottom, on the short side:

This results in extra material left behind in the main pocket:

2. I don't know how to machine the cutouts in the sides of the part, highlighted here:

Any advice would be appreciated.

You should upgrade to 0.19 (use the AppImage on Debian) and try a pocket with Extensions.
