Open in the PARTdesigner the part to be dimensioned.

Open the Dimensions [Dimensionings] docking window using the toolbar icon of the same name . If required, you can detach it as a separate window using drag & drop.

-> The dimension points (blue) and connection points (green in individual parts, gray in assemblies) are now displayed.

Make sure that the dimensions are displayed in the 3D view.

If necessary, click on the Show dimensions [Show Dimensionings] button in the 3D view toolbar.

Click on the Add new dimensioning [Create new dimension] button.

-> An "AUTO" dimension line appears in the upper dialog area and the type [Type] HORIZONTAL is created by default under Mandatory parameters. (Correct here in the example. Otherwise, adjust the selection in the list box)

As "ID" and "Description" set "L".

Under Mandatory parameters -> Views, select the desired 2D views on which the dimensioning is to be displayed. Here in the example Front+ Z.

Views that contain a dimensioning can be recognized in the 3D toolbar by a corresponding icon with a dimensioning line .

Now determine the starting point [Start point] of the dimensioning.

Select the desired connection point [Connection point].

-> The connection point [Connection point] is highlighted in red.

Call up the context menu and select Use as. [Use as ...].. -> Start point.

-> The Start point is entered in the input field.

Proceed in the same way for the end point [End point].

Select the value BBOX (Bounding box) in the Position list field and the value -DIST*12 (here in the example) as the distance dimension (BBOX) [Offset (BBOX)].

-> As soon as all mandatory parameters [Mandatory parameters] are set, the dimensioning appears in the 3D view.

You can now modify (e.g. text) or set (e.g. arrow size [Arrow size] ) optional parameters [Optional parameters] as required.

Text:

Tip You can see the exact designation of the part name under Starting point [Start point], for example.

You can find a complete overview of PARTdesigner expressions under Section 14.1, “PARTdesigner-Expressions ”.

Variable mapping

Once the variable name is entered, the editing icon is displayed.

The user can later change the characteristic to be exported here. Compare Section 3.1.7.6.6, “Change characteristic via dimension labels ” in PARTsolutions user manual

Adjust the value for font size accordingly (here in the example "DIST").

Set the arrow size [Arrow size] and arrow factor [Arrow factor].

Set accuracy [Accuracy].

When all settings are set, click on Save changes .

-> The undo icon disappears at all changed parameters.

Now click on 2D derivation .

The set dimensioning is also used for 2D derivation.

When exporting to the CAD system the dimensioning is transferred as well.
