About the 3DCS Tolerance

It is generally recommended to place a 3DCS Tolerance in the part containing the points to be toleranced.

Select the Tolerance icon from the Model Creation toolbar and then select the part in the Tree window in which you would like to create, modify, or delete the tolerance. A Tolerance List dialog box listing existing Tolerances and different Tolerance types to create is displayed. This same dialog box can be also found by double-clicking on the Tolerance List in the Tree window.

The Tolerance function will always apply to the part in the Tree, which if a part was selected before opening the Tolerance List dialog.  If no part in the tree was selected, the Tolerance function will prompt you to select a part. The part you select in the tree will contain the Tolerance you wish to Create, Modify, or Delete.  

To Create a Tolerance:

Select the appropriate tolerance type from the drop-down list (Linear, Circular, etc.) and click on the [Add Analyst] button. The Tolerance dialog box is displayed. Parameters which are specific to the particular tolerance will be described on its specific help page (see the above listing). When finished entering parameters, the tolerance may be saved by clicking the OK button or the Apply buttons. The Apply button keeps the Tolerance List window open, allowing you to immediately enter another tolerance. OK will save and close the Tolerance dialog box.  The Cancel button exits the dialog without saving it and returns you to the Tolerance List window.

To Edit a Tolerance:

All the existing tolerances in the part will appear in the Tolerance List. Select a tolerance and then Right-click in the Tolerance List and select the [Modify Tolerance] button, or double-click on the tolerance in the list.

You can also select the Tolerance List, select a part and then select [Modify Tolerance] in the dialog.

Modify the tolerance as required.  When finished modifying parameters, the tolerance may be saved by clicking the [OK] button or [Apply] button. The [Apply] button keeps the Tolerance List window open, allowing you to immediately check the tolerance (Nominal Build and Deviate). [OK] will save and close the Tolerance List dialog box.  The Cancel button exits the dialog without saving the tolerance and returns you to the Tolerance List window.

To Delete a Tolerance:

Select a tolerance in the Tolerance List dialog and press the [Delete] button. Click [OK] in the confirmation window to delete the tolerance. To delete multiple tolerances at the same time, select  tolerances by either drag-selecting them from the list, or clicking on each one while holding the Ctrl key, then press the Delete button.
