Defining Tolerances

3DCS Tolerances are used for applying tolerance directly to DCS Points or Feature Points.  Any point with a DCS Tolerance associated to it will deviate according to the Distribution and limits of the tolerance.

How to Create a new Tolerance: It is recommended to place a 3DCS Tolerance in the part containing the points to be toleranced.

1.Select the DVTI_tolearncelist Tolerance list dialog from the Model Creation toolbar.

Tolerance Pick Component

2.Select a part in the Model Navigator or select [Root]. Selecting Root will create the tolerance at the top level assembly. A Tolerance List dialog is displayed. The same dialog can be accessed by double-clicking on the Tolerance List in the Tree window.

3.Select a Tolerance from the list and click on the [Add] button. The Tolerance dialog box is displayed.  

4.When finished editing the Tolerance, select [OK] or [Apply]. 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.

5.Users can immediately check the tolerance by setting the model to DVTI_dcsNominalBuild Nominal Build and then DVTI_dcsDeviate Deviate.

 

How to edit an existing Tolerance:

All the existing tolerances will appear in the Tolerance List in the Model Navigator. 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.

1.Double-click on the DVTI_tolearncelist Tolerance List and select the tolerance and then Modify, or right-click on a tolerance and then select [Modify Tolerance].

2.Modify the tolerance as required. Click [OK] or [Apply] to apply the changes.

3.Users can immediately check the tolerance by setting the model to DVTI_dcsNominalBuild Nominal Build and DVTI_dcsDeviate Deviate.

How to delete a Tolerance:

1.Open the DVTI_tolearncelist Tolerance list dialog.

2.Select a tolerance in the Tolerance List dialog and press the [Delete] button.

3.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 Shift or Ctrl key, then press [Delete].

How to copy an Existing Tolerance:

4.Open the DVTI_tolearncelist Tolerance list dialog.

5.Select a Tolerance and then select [Copy].

a.Right-click on a Tolerance in the Model Navigator and select [Quick Copy]. Quick Copy will copy the tolerance with all customized parameters (Range, Offset, Features, etc.).

b.If copying Tolerances to a new part, right-click on a tolerance in the Model Navigator and select [Copy]. Right-click on the new part and select [Paste].

To Convert a Tolerance from one type to another:

Double-click the Tolerance list and press the [Change Type] button and select the new tolerance type from the list.

Some tolerances require additional information such as vectors and that may need to be manually set.

Reordering Tolerances in the Tolerance Window:

1.Highlight the tolerance in the Tolerance List to be moved.  

2.Select the Switch To: drop-down list arrow, or use the Down Arrow or Up Arrow arrows, next to the Tolerance list field. One or more Tolerances in the list can be selected and moved in the list.

3.Select the index number from the list which you would like the highlighted Tolerance moved to.

4.The highlighted tolerance will move to the place specified by the Switch To index.


Using Feature Groups in the Tolerance list dialog:

Users can add Feature Groups to the Tolerance lists, to allow Tolerances to be stored in a customized list.

While a Feature Group is active in the Tolerance list dialog, the next created measure will be created in the Feature Group.

If any Feature Groups exist in the Tolerance list, only the selected Feature Group List will show the available Tolerances.
