With the release of Design Tool version 2.5 it is possible to group several parts together. With grouped parts it becomes easier to move parts around in the 3D world. To group several parts, select them and then click on Home->Grouping->Group, which creates a group consisting of the parts. Grouped parts can then be ungrouped by selecting one of the parts within the group and then clicking on Home->Grouping->Ungroup. 

When selecting one part that is in a group, then all parts in the group will be selected. If the group is already selected then the only selected part will be selected so properties can be changed on that part.

Groups are also hierarchy structured, which makes it possible to create groups containing other groups. This way several conveyors can be grouped together and moved as one.
