components cross

[Dodo1]

Good evening,
I'm a first-armed student with sw.
My parts, in the assembly phase, cross each other as if the program did not recognize that they were solid.
Could someone help me solve this problem?

rather vague explanation
Did you do the tutorials?

If you still need to couple the components is not a problem, indeed it would be if you had to circumnavigate other parts to drag them where you need (think if you had to insert a part inside a container. . . )
if you have already coupled and want to verify some movements and any contacts you have to activate the command moves and put the option identifies collision.
