Launch a program to only specific resources

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 : what is the effect of setting cpu.cpu_quota_us in cpu cgroup? but it is unanswered - although it points to my solution maybe?

Have you tried just launching openscad with nice? That doesn't allow you to set specific limits, but it will run a program with a lower priority:nice openscad. That won't help if the problem is RAM, but it should make your system more responsive/ Let me know if that works and I can post an answer.

Something like askubuntu.com/a/510936/158442 or askubuntu.com/a/94743/158442?
