How to Employ the AutoCAD Group commands in Civil 3D
Comments
Jerry Bartels of Autodesk covers the quick and dirty basics of the AutoCAD Group commands.
These include GROUPEDIT, GROUPDISPLAYMODE, CLASSICGROUP, and UNGROUP.
From the Jerry's YouTube Channel.
and the Civil Imersion blog.
AutoCAD employs the drawing ObjectIDs to collect the entities in a Group.
Obviously if these are things like a Survey point (not a COGO point) the IDs will change with Survey Insert and Remove Point commands.
The same warning applies to Civil 3D Data References if they are deleted and referenced again.
The Selectable option can be useful if you need to make sure you don't bash things accidentally.
The backside is that in an XREF Bind or Insert-Explode situation the properties of the Group still apply.
If you employ GROUP, the others who work with you need to know. It adds AutoCAD collection behaviors where people may not expect it.
