How can I import FreeCAD from the python console? I'm trying to write a script that can manipulate a given FreeCAD file, but I can't even get FreeCAD imported into the python console on a system where FreeCAD is installed.

user@disp7637:~$ sudo dpkg -l | grep -i freecad
ii  freecad                                       0.19.1+dfsg1-2+deb11u1             all          Extensible Open Source CAx program

How can I import FreeCAD in the python console?

A handy program for measuring the pixel dimensions of something on-screen is screen ruler: sudo apt install screenruler ; screenruler I like how you can place it anywhere on your screen and it stays on top of all other applications as you use it. I'm hoping to find something similar to this that's a protractor instead of a ruler. I searched for "protractor" in the repository of Debian 11 and got no results: sudo apt-cache search "protractor" Such a tool would be great for measuring angles on-screen. However, ultimately, I will likely need something that can actually draw a line based on a specified angle. Hopefully I won't have to learn something as sophisticated as AutoCad in order to accomplish this. What's the simplest way to measure and draw angles in Linux?

when I run sudo pacman -Syu pacman throws this error:

:: Synchronizing package databases...
 core is up to date
 extra is up to date
 community-testing is up to date

:: Starting full system upgrade...

error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: opencascade74 and opencascade are in conflict

I tried to clear cache with sudo pacman -Sc but error remains When I try to remove opencascade package but:

sudo pacman -R opencascade
checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: removing opencascade breaks dependency 'opencascade' required by freecad

How can I get around this error to upgrade my system ?

I am currently on a modified version of Debian-standard, jessie, using xfce and LightDM with some AMD drivers for the GPU. But my issues are that I am using an 8 core AMD FX 8320, all cores are being detected and are running fine in Linux, but for some reason FreeCAD is only using one (not even entirely) to load a small file. I was thinking maybe if it could utilize multiple cores on my system then it could load the 1.4 MB DAE file without halting the system and taking more than an hour? Other specs that may be useful?: - 8GB 1600mhz DDR3 RAM - A not-so-great ASRock motherboard. - 1TB HDD.

Question: -- How can I launch a program such that it only uses X ram and Y CPU cores, etc? I happen to be using Ubuntu in this case, but since I often am on other distros, I need a general GNU/Linux solution. Example use: -- I have a program, openscad, which I want to use to convert an image from 2D to 3D. It runs snappy enough on 50x50, but I would like 500x500, and this effectively takes down an i7 such that I cannot use other programs easily - such as the file manager or firefox. On an older machine, it was basically only responsive to kernel level reboot not even switching to a different virtual terminal with F1 etc. Search so far: -- I think what I am looking for is something called a "quota" manager, but I keep finding stuff for hard disk space, and I just want the computer to remain usable. I'm not sure exactly what I'm looking for but I know its effect. I found : https://unix.stackexchange.com/questions/417506/what-is-the-effect-of-setting-cpu-cpu-quota-us-in-cpu-cgroup but it is unanswered - although it points to my solution maybe?

I would like to do some CAD work on Linux (Fedora). I have no experience in CAD, so I have to learn it from scratch. Do you know an CAD Tool for Linux which is easy to use? I prefer an easy tool over a fully functional, jack of all trades program.
