I built 2 separate piping systems (separate I mean that they are not conected with pipes or anything, but they are "running" very close to each other)
I whant to know if they have any intersections - to check that everything is all right.
On skacthes there were global coordinate of some elements, but Caesar begins every time from (0,0,0)
I'm interested in if it is possible to move all structure in exact place?
or add (include piping file) in direct place???????

Yes you can position your models in 3D space. Just click the "Global Coordinate" toolbar button (on the left side, near the top).

Even if you do this, you'll have to manually check for interference - CAESAR II will not do this for you.

OK thanks a lot
