Why are the equations not deleted when I delete a feature/sketch/dimension?

I use equations all the time and when I delete the features that they belong to the equation doesn't get deleted which throws out errors.

Other times I delete a bunch of dimensions that used equations and then re-dimension the whole sketch and the equations are still there and related to a dimension to which it shouldn't be!

It's best if they are independent. If you remove equations from your box by removing the dimension you can really screw up models. You lose the syntax and if you save the file you might really get behind.

Comment 1. Yes it can be frustrating when you delete dimensions that are equations that you know you will not use again. The work flow is to open the equation editor and remove them.

Comment 2. Why are you deleting all the dimensions just to add back new ones. The equations are not set in stone. Highlight your dimension that has the equation = blah blah blah and just type over it. It will remove the equation from your equation manager. You can do this in the sketch as well if you highlight over the equation.
