So I have selected a helical gear from my toolbox and right clicked on it and selected "Create part". It then displays a gear with all the properties in a left hand column which includes module, shaft diameter etc. However after I click the green arrow at the top of the column I have no way of bringing those properties back up. I only have geometric properties like I have manually created the part.

I know it is simple as I have done it before but can someone remind me how to bring up those editing properties?
