Function GetFirstDisplayDimension() As System.Object

Dim instance As IFeature
Dim value As System.Object
 
value = instance.GetFirstDisplayDimension()

System.object GetFirstDisplayDimension()

System.Object^ GetFirstDisplayDimension(); 

Return Value

First IDisplayDimension object for this feature, or Nothing or null if there are no dimensions for this feature

Before you can get a feature's IDisplayDimension, use IModelDoc2::SetUserPreferenceToggle and swDisplayFeatureDimensions to display them.

All dimensions on this feature its sub-features are returned by either IFeature::GetFirstDisplayDimension and IFeature::GetNextDisplayDimension or IFeature::EnumDisplayDimensions. In the user-interface, this is equivalent to double-clicking a feature in the FeatureManager design tree to display all of the feature and sub-feature dimensions.

If you call this method from a sub-feature (for example, the sketch of a boss-extrude), then the IDisplayDimension object returned by IFeature::GetFirstDisplayDimension and IFeature::GetNextDisplayDimension contain only the dimensions found in the sketch.

Do not use IAnnotation::Visible property to modify this method's return value.

This method might not return the same display dimension every time it is called.
