If you're working in an Autodesk Inventor assembly and you're working top down, it's likely that you will be projecting sketch geometry from one part to another.
When using the Project Geometry tool in a 2D sketch from one part to another, depending on how you have your Application Options set, the geometry you project will be associatively linked to the source. This means if the source changes, the projected geometry will also change. This can save you a lot of time updating and positioning.
However, if you just want to project geometry so that it isn't associative, there is a quick tip that can help.
Just hold down the Ctrl key on the keyboard when you select the geometry to project and you will end up with the geometry projected but not associative.
This shows how associative projected geometry is shown within the model browser by projecting (without holding the Ctrl key):
This shows how non-associative projected geometry is shown within the model browser by projecting (holding the Ctrl key):
If you find yourself using this tip regularly as you don't want to have projected sketch geometry associative, you can change your application options by taking the tick out of the Cross-Part Geometry Projection option:
