Bathtub/shower enclosure rough-in

[gstprecision]

Hi, I am just starting using X5 and I was wondering what was the best way to make rough-ins for enclosures like bathtub/shower enclosures?

I tried different approach and so far the easiest option I found was to use the pass-trough and expand to fit. The program does not allow to just drop the enclosure in place or automatically frame around such enclosure.

Any better way or tricks?

Thanks
