mounting hole keyways #10

Closed Neon22 closed 10 years ago

Neon22 commented 10 years ago

To attach a gear to a shaft is frequently done with a slotted keyway instead of a single hole. In metric there is a preferred slot size based on shaft diameter. Most of the time this resolves to a single value for a given diameter of shaft. (py 737 in doc referenced in profile shifting issue #9). I don't know what happens for US imperial inch based systems.

So we could modify the hole to add a keyway as an option (basically cutting a rectangle slot). What do you think...? Do you know if imperial also has a table we can lookup for preferred key slots sizes ?

I'd leave it up to the user, to add a keyway. The procedure is fairly simple: Draw a rectangle that intersects the mount hole diameter; select both your rectangle and the gears path, apply Path -> Intersection.
