Extrusion starting from an inserted distance: in Inventor's extrusion features there is only the option to start extrusion from the sketch plane or from a selected face. It would be very useful in order to avoid having to create additional reference planes and multiply commands to achieve your needs, to have the possibility to also enter a distance in the "From" options of geometry input. For example in creating a key-way for tab in a shaft I can avoid having to create a tangent plane on which I will create the sketch for the extrusion of the key-way. I will create the sketch on the axial plane and enter the two distances to create the key-way. The first distance will be the radius of the shaft and the second distance will be the depth of the slot.
