User Guide: Groups

If the imported OBJ file contains any polygon, material or smoothing groups, then these will be listed in alphabetical order under the Groups panel. One of more groups can then be selected in the list, and the polys that belong to those groups are marked.

Box and Pack by Group: If the polys of the selected groups have been flattened already, then this button will place all the shells into boxes, a separate one for each group, and then packs them all automatically.

Detach: All marked polys are detached, exactly as if you had moved the mouse pointer over them and typed the Enter hotkey.

Select: If the marked polys have been flattened already, then the Select button will select those shells. This would allow you then for example to move all those shells off to one side for other processing.

Box: Again, if the marked polys have been flattened already, then the Box button will gather all of those shells together into a Pack box.

Various methods can be used to select groups in the list:

LMB: Selects just that group, deselecting all others. Click'n'drag to select multiple groups.

Ctrl-LMB: Toggles that group, leaving all others as they are. Click'n'drag to toggle multiple groups.

Shift-LMB: Selects all groups between this and the previous selection.

Collapsing a group list (i.e. clicking on Polygon, Material or Smoothing) will deselect all the groups in that list.

Editing

These buttons can be used to edit the group list and members.

New: If no group name is selected, this opens up a text entry field where you can type in the name for a new group. Type the Enter key to save the name. Any G key marked polygons, or LMB selected shells, will be moved into this new group.; If a group is selected, this opens up a text entry field where you can edit the group name. Type the Enter key to save any changes.

Add: This adds all G key marked polygons, or LMB selected shells, to a group in the list. Click the button first, then click on the group name. If those polygons were already in one or more groups, they will stay as members of those groups.

Move: This moves all G key marked polygons, or LMB selected shells, to a group in the list. Click the button first, then click on the group. If those polygons were already in one or more groups, they will be removed as members from those other groups.

Del: If no group name is selected, this deletes all empty groups from the list.; If a group is selected, this removes that group name from the list.
