Inventor Slot Mid Axis


SMA (Slot Mid-Axis) is an add-in for Autodesk® Inventor®. it helps the users to quickly and efficiently create Center Axes for Slots, saving you a lot of time and efforts.


Autodesk® Inventor® doesn’t have a direct way to create Middle Axes for Slots, which can make it challenging to center a hole from one plate to the middle of a slot on another plate.
Users often add constraints based on the slots’ width and length, which can be time-consuming and require updates if the parameters change later.

General Usage Instructions

With SMA (Slot Mid-Axis), you can create a Middle Work Axis for Slots in just one click.
The created Axis will remain in the middle of the slot, and changing slot parameters won’t affect the created Axis.
It will always point to the middle of the slot, making it a convenient solution for centering holes from one plate to the middle of a slot on another plate in Autodesk® Inventor®.

SMA (Slot Mid-Axis) can be started from both Assembly and Part Documents, allowing users to create a Middle Work Axis for their Slot in just one click regardless of the document type they are working on.
