Get DimXpert Display Dimensions and Feature (C#)

This example shows how to find out if an annotation is a DimXpert display dimension, and, if so, how to get its DimXpert feature.


// Preconditions:

// 1. Add SolidWorks.Interop.swdimxpert.dll as a reference

//    (in the Project Explorer,

//    right-click References and click Add Reference).

// 2. Open <SolidWorks_install_dir>\samples\tutorial\api\plate_tolstatus.sldprt.

// 3. Click View > Toolbars > DimXpert (select the first instance of

//    Toolbars on the View menu).

// 4. Click the Auto Dimension Scheme button on

//    the DimXpert toolbar.

// 5. Make sure Chamfer is selected in Feature Filters

//    on the Auto Dimension Scheme PropertyManager page, then

//    click the checkmark to close the page.

// 6. Open an Immediate Window in the IDE.

// 7. Run the macro.


// Postconditions: DimXpert display dimensions are added to the model.

// NOTE: Because this part document is used by a SolidWorks online

// tutorial, do not save any changes when closing

// the document.
