Fusion 360 is a great program. My biggest frustration is that 1/3 of the automatic constraints created are not appropriate. In a large design, that ends up being hundreds of wrong constraints that end up wreaking havoc when you try to make a seemingly simple design change. I know you can hold Control to disable auto constraints, but that does not always work (e.g. moving a sketch object, it brings up the menu). I desperately wish there were a way to turn off auto constraints in a preference setting.
