To Enable Parametric Dimensions to be Transferred at Drawing View Creation

When an Autodesk Inventor linked file is created, the link is able to read parametric dimensions from the part/assembly file. However, to display parametric dimensions on a drawing view, they must be transferred to paper space, typically, at the same time the drawing view is generated. You can however opt to add parametric dimensions later

Note: Inventor Link is available only on 64-bit systems, and it is not installed by default.
  1. At the Command prompt, enter OPTIONS.
  2. Click the AM:Drawing Tab
  3. From the Parametric Dimension Display section, select the Active Part Views option.
  4. Click OK. Whenever a drawing view is created, parametric dimensions will also be created.
