Hi,
you can get work step 2 in a very easy way. If you want to move each cylinder
separately, you have to put each
cylinder into its own transformgroup as you already did it. Next you have to assign
all 20 transformgroups to the
transformgroup of your plate as child objects. Then each time you move the plate all
cylinders will get moved in
the same way. If you want to detach all cylinders by clicking onto the plate, just
put the transformgroups into a
branchgroup and assign it to the transformgroup of the plate. You also need a behavior
that will detach (or
re-attach) this branchgroup when you klick onto the plate. You have to set the
according capabilities to avoid
exceptions like the one you got.
hope this helps
Gernot
