Examining Merged Entities

There are several mechanisms for examining which entities have been merged. The most useful mechanism is assigning all merged or unmerged entities of a specified type to a group, and examining that group graphically. This process can be used to examine the outer shell of an assembly of volumes, for example to verify if all interior surfaces have been merged. To put all the merged entities of a given type into a specified group, use the command:

Group {<`name'>|<id>} add [Surface | Curve | Vertex] with Is_merged

To put all the unmerged entities of a given type into a specified group, use the command:

Group {<`name'>|<id>} add [Surface | Curve | Vertex] with Is_merged=0

Entities can also be labeled in the graphics according to the state of their merge flag. See the Preventing geometry from merging section for information on controlling the merge flag. To turn merge labeling on for a specified entity type, use the command

Label {Vertex | Curve | Surface} Merge
