As I said, it's really not possible to have a single tool for a single job, because in CAD sometimes you have to mix different workflows to achieve a complex shape.
In particular it's bad to mix Part and PartDesign Workbench tools, as each is designed with a different philosophy in mind, and their tools aren't exactly compatible. They both internally use the OCCT geometrical kernel, but they expose a different interface to work with objects.
There is no solution but to gain experience with the system. Very often it's clear that the error is with the user and not the program.
This is a pattern of many threads:
It's obviously an exaggeration, but a lot of people get confused because they just don't have enough experience in many cases.Post 1. OP: I tried this and it doesn't work! It's a bug!
Post 2. Experienced user: you have to do it this way, and use this tool with that feature, and not this one.
Post 3. OP: thank you very much! That did it! I'm a complete noob, I've never drawn anything with a pencil, and I've never drawn anything in the computer; as a matter of fact, it's the first time I ever use a computer! Thanks!
