Dimensions in_through Viewports

Dimensioning within a viewport in paper space will provide dimensions of the object. The dimensions will be scaled correctly according to the scale of the view.
Misleading dimensions can result if the viewport is not exactly parallel to the object. Therefore attempting to dimension an Isometric view by this method is not advised.
The dimensions will be associative to model and drawing elements through viewports in paper space layouts.  These associative dimensions will update with model and drawing changes. This is automatic, but only applies to the following objects:

• Solid objects
• 2D objects
• Surface objects
