LDCad Add brick to an existing group

[Philippe Hurbain]

is it possible to add bricks to an existing Group. I know how to create a Group but when I finished the Group I found no way to add another brick later on.

Select group and part(s) you want to add, then right click -> grouping -> add selection to group. In LDCad 1.6, if selection contains several groups, this creates a multi-level group.
