Separating, Grouping, and Ungrouping

Cic_3147.ENU.bmp Separate

Sometimes objects may consist of more than one volume. This may result from an operation in form•Z or such objects may be imported from other applications. This tool can be used to separate the volumes of such an object and make them independent objects. To execute this operation, with the tool active, click on the object whose volumes ought to be separated. The result is produced immediately. The prepick method can also be used to separate the volumes of a number of objects in one step.



Cic_3146.ENU.bmp Join Volumes

This tool makes one object out of two or more other objects. Only solids with solids and surfaces with surfaces can be joined. Open lines and wires are refused. The resulting new object replaces the original objects that were joined. The operation can be applied using either the postpick or prepick selection mode.



Make Reference Reference Object

This tool is similar to and is executed as the Join Volumes tool. It has no restrictions in terms of what type of objects can be picked. However, the resulting object is not a real object and is not accepted by most operations, but can be transformed and it is snapable. Its role is to serve as a reference for other objects.



Group.tif Group

The display of groups in the Objects palette.

This tool is used to group objects. To group two objects and/or groups, with the tool active click on the two objects/groups. To group more than two objects/groups, with the tool active, shift-click on the objects/groups you wish to group, then release the shift key and click anywhere in the project window. The group is constructed immediately. The prepick method can also be used to group any number of objects and/or groups.


After their grouping, members of a group look the same as they did when they were independent objects. However, they now pick as a single entity and certain operations can be applied to the group, such as moving it around. In addition, the structure of the group is visible in the Objects palette, as shown.




The grouping operations can also be executed interactively through the Objects palette. Click on the cross (Cic_8029.ENU.png) icon found on the right of the title bar of the Objects palette. This creates an empty group that is listed in the palette. Click and drag the name of an object listed in the palette onto the group name. This makes it a member of the group. More objects and/or groups can be dragged this way to make them members of the group.



Ungroup.tif Ungroup

The Ungroup tool options palette.

This tool is used to un-do groups. With the tool active, click on the group you wish to dismantle. This can occur at only the highest level of the group or the complete group may be dismantled, depending on an option selected from the Ungroup tool options palette.



Remove from Group.tif Extract from Group

With this tool you can extract an object from a group. With the tool active, click on the object you wish to extract. The object is removed from the group immediately.



Add to Group.tif Add to Group

With this tool you can add an object to a group. With the tool active click on the object, then on the group to which it will be added.


Extract from Group and Add to Group are intended to allow objects that are members of groups to be edited. You first extract the object from the group and make the desired revisions. You then add the object back into the group.
