assembly relationships

[onefjef]

...
Example:

Two assemblies. Parts in 2nd assembly relate to both each other and offset from faces in first assembly.
...

Every time I try to set mate relationship of part in 2nd assembly to face in 1st assembly I get a relationship conflict error. I'm in the top level assembly while doing this.

How can I relate a part in to both parts in that assembly and parts in other assemblies?

May be by making the sub-assembly adjustable ?

Adjustable assembly may be the way to go by the sounds of it.

Only thing is you have to leave out the relevant constraint in the sub assembly.

E.G. if you had some kind of piston as the sub assy you'd alight the axis and give it an angular orientation however you wouldn't define how far along the stroke the piston is.

You can either leave that constraint out altogether, have it in, position it adequately for the sub assembly drawing and suppress it (incase you need to adjust it in future) or put the relationship in, position it and then change it to floating offset (again incase you need to change it later).

I've pretty much taught myself adjustable assemblies from SE help, perhaps someone else can explain it better. I even asked a trainer about it last year during advanced assembly training but he didn't seem to know any more than me (maybe less).

I've used them before but for a different purpose. I don't know why I didn't think of that.

Thanks to both.
