Hi Maree,If you are to import 3D objects in .GSM format, you can import
that object via the object library. In the object library dialogue box,
there is a small button located at the bottom of the screen where it
allows you to call out the object lib...
@Daniel_He If you are using the Beam tool to create the pipe connection,
try changing the Beam tool "Geometry method" to "Chained" so this way
your beam will stay connected as you go along. Hope this helps.
