3D Modeler Options: Operation

The Tools > Options > 3D Modeler > Operation options allow you to select options for clone, coordinate system, model editing, and model save operations.

1. By default, the modeler will delete tool objects when performing tasks such as uniting, subtracting, or intersecting objects. The user can specify that the modeler should make a copy (clone) of the tool object prior to the operation, allowing the object to remain available for subsequent operations. To specify when to clone tool objects, select or clear the following check boxes in the Clone section:
   • Clone tool objects before uniting
   • Clone tool objects before subtracting
   • Clone tool options before intersecting
   • Clone tool objects before imprinting
   • Clone tool objects before projecting
2. In the Coordinate System section, select or clear the Automatically switch to face coordinate system check box.

   By default, the modeler operates within the user-selected coordinate system. If this option is enabled, you can select a face and when a new object creation is started, the modeler first creates a face coordinate system consistent with the selected face, and the new object is created within the face coordinate system. If this selection is unchecked, you must manually create a Face Coordinate System before creating an object related to it.

3. For the Model Edit section:
   • If Delete invalid objects created during split operation is checked, the modeler deletes invalid objects created during split operation. If not checked, invalid objects can be created. Validation issues warnings.
   • Select or clear Automatically imprint wrapped sheets.
4. In the Model Save area, you can enable/disable being prompted for model history cleanup. You can also specify the number of actions on a part that will cause a prompt. The default value is 50.
