Hello, we are in the middle of migrating from autocad to solidworks (and epdm)

Previusly we made every drawing manually and now we have some problems trying to implement a good workflow introducing some "smart" in our design process (to reduce projects times)

This is one a little insidius:

We made small gates, grouped in a assembly files composed by Column-gate-column combinations. Each of the elements (columns / gates) are assemblys with multiple configurations (example we have ColumnA composed with ColumnA element and AccessoriesA, ColumnA element and AccessoriesB, columnB with AccessoriesA and so on)

We deploy ~10-100 of this assembly in a standard project. The problem is this:

each gates have a range of lenght (for example Gate1 could be from 500mm to 700mm, Gate2 700-900mm and so on). We import the whole assembly file in the project but we cannot made it extend becouse it's fixed and we can have multiple Gate1 in a drawing, so if i change the Gate1 assembly to fit a gap of 650 mm for example, all the Gate1 files where updated and maybe in others places in the project the Gate1 visually go in interference with other objects.

I really don't want to virtualized each assembly into the main assembly drawing to get them right-displaying.

Any hint?
