Object Groups allows designers to establish objects
repeatedly over a range, with dynamic positioning (and rotation)
relative to a design string, code or surface. This is very useful for
placing signs along the design (curve signs, warning, regulatory) and for
repeated items such as bollards, trees and street lighting (with street
lighting oriented perpendicular to the sring).
The Object Groups interface makes it easy to add items at
any position along an alignment, to remove items from the group and to add
items. The Object Group list itemises each object added - users can
change the chainage, the object type (.obj) and the object scale.
Objects can be deleted using the Object Edit tools in Model
Viewer, however are preferably managed using the Object Groups form.
