Check assemblies for misaligned holes.

General Usage Instructions

Hole Check Addin is easy to use. Just open the assembly you want to check in Autodesk® Inventor®. Then click the Check Assembly button in the tool bar. If any issues are found, they will be displayed clearly in the results window. Double click the issue to go to where it is in the model, or single click to highlight it.

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 tool bar. Then you can change settings to control how the results are displayed or configure the checking parameters. 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 Addin.
