Q - question

The option "Open Express" is grayed for an Inventor assembly.

A - answer The dialog "Open" in Autodesk Inventor 2014 offers the button "Options" when opening an assembly file (IAM). In the subsequent dialog "File Open Options" you can choose whether to open the assembly file in the fast "express mode". In some cases, this option is inactive, grayed out.

There are several possible reasons for this disabled state:
  1. That particular assembly file was not yet migrated to the version 2014
  2. The express mode was disabled in the dialog "Application options" (the ribbon tab "Tools", the icon "Application options", the tab "Assembly", the option "Enable Express mode workflows (saves graphics in assemblies)")
  3. The graphics mode "Compatibility" was set in the dialog "Application options" (the tab "Hardware", the option "Compatibility")

How to re-enable this option? You can:

  1. Migrate the assembly file to the version 2014
  2. Check the option in the dialog "Application options" > "Assembly"
  3. Switch to the mode "Performance" or "Quality". In this case a simple switching is not enough. You will need to restart Inventor.

    If the option is still not available after you restart Inventor, your assembly was probably saved under the mode "Compatibility". You will need to open the assembly and re-save it. After you re-open it, this option will be active again.

When saving graphics to the assembly file, Inventor respects the current graphics mode. To make the express mode available, you need to save your assemblies in the modes "Performance" or "Quality".
