Gray Point Software, LLC
Check assemblies for misaligned holes.

General Usage Instructions

Hole Check is easy to use. Just open the Hole Check application and the assembly you want to check in Autodesk® Inventor®. Finally, click the Check Assembly button. If any issues are found, they will be displayed clearly in the application. Double click the issue to go to where it is.

During the checking process, you will not be able to use Inventor. After the process is finished you will be able to use it again. To check another assembly just open it in Inventor and click the Check Assembly button again.

To change any settings, click the gear icon in the top right corner. Then you can change settings to control how the results are displayed, configure the checking parameters, and force the app to stay on top of other windows. Note: You must enable the Include Circular Features option in settings to check circular features.

As always, it is important to save your work often. In case of any unexpected errors, you should save your work before running Hole Check.




Run the hole-check-X.X.X.msi and follow the wizard to install the application (Replace the X’s with your version). The installer requires administrator privilege to install, please turn off your UAC(User Accounts Control) before installing it.

To remove this application, uninstall the application via your system's Control Panel.
