I don't know why, but I can't draw a new part in an existing assembly. I start a new assembly. Then I create my first piece. Normally, when I create a second piece, I should be able to relate the dimensions of the second piece to the first. But I can't do it. I've drawn like this before, but today I can't do it. Maybe I changed something in the settings. I don't know. Can you help me please?
It's normally quite simple, without having seen your file I have the impression that you are not creating the second part correctly. If you don't get your way with the online help, post your ASM with a pack and go
