This lesson was written as a response to a question asked by an anonymous reader in the lesson: Using and Understanding Linked Parameter in Autodesk Inventor. I hope this answers your question.
At a time in your design workflow, we might want to link an existing parameter in a part file to another part or assembly. This way, changes to the parameter will reflect in the other part or assembly. In this lesson, we are going learn to link an existing parameter in a part to another part or assembly.

PROCEDURES:


For this lesson, I have uploaded the dataset: Linking_parameter_between_parts_mod.zip to a public file server. Download the zip file, and extract the files to the directory of your active project.

  1. Open linking_parameters_shaft_part.ipt.
  2. Go to the Manage tab > Parameters panel and click on Parameters. Examine the existing parameters. The parameters are consumed in the model.
  3. Open linking_parameters_hole_part.ipt.
  4. Go to the Manage tab > Parameters panel and click on Parameters. Examine the existing parameters. The parameters are also consumed in the model.
  5. Our aim is link the Shaft_Dia parameter in the linking_parameters_shaft_part.ipt to the Hole_Dia parameter in the linking_parameters_hole_part.ipt. So that if the Shaft_Dia parameter is changed, the Hole_Dia parameter will update accordingly.
  6. Switch to linking_parameters_hole_part.ipt. Go to the Manage tab > Parameters panel and click on Parameters. On the Parameters dialog box, click Link at the bottom of the dialog box.
  7. On the Open dialog box, change the Files of type to Inventor file (*.ipt, *.iam). Select linking_parameters_shaft_part.ipt and click Open.
  8. On the Link Parameter box, double click the Shaft_Dia to add it to the parameters that would be linked from linking_parameters_shaft_part.ipt to linking_parameters_hole_part.ipt. Click Ok
  9. The Shaft_Dia has been linked to the active part.
  10. On the row for Hole_Dia, click the equation 100 mm and then click the arrow. Click List Parameters and select Shaft_Dia. Click Done to close the Parameters dialog box. Save the file.
  11. The Hole_Dia parameter has been equated to the Shaft_Dia parameter.
  12. Open linking_parameters_shaft_part.ipt. Change the Shaft_Dia parameter to 200mm. Save the file. Open linking_parameters_hole_part.ipt. Click Local Update on the Quick Access Toolbar. The Hole feature updates accordingly.

This method can be used for linking parameters between parts and assemblies and vice versa. I hope this tutorial was useful. Drop a comment you liked this or ask any questions. Have a lovely day.
