I sometimes like to have duplicate parts laid in the assembly as semi transparent to show alternate positions etc. Sometimes preferred to different configurations of the assembly.
However, as I need to keep a close eye on overall mass, I don't want these additional parts to be counted. Without saving duplicate copies of the relevant parts and setting their mass to zero is there any way of setting certain parts in the assembly as having no contributing mass?
I hope my explanation was clear!
Thanks for all feedback.
