This seems to be a problem I have with adjusting the scale on a part. I shrink it, do the adjustments, then enlarge it again. BUT the dimensions are off no matter how carefully I adjust the scale values or make sure I'm still scaling about the same point. For example I take a 2in cube, shrink it by a factor of 0.75, then enlarge it by a scale of 1.25, and the cube is now 1.875in instead the 2in I wanted it to be.
Basically I need the math or formula to accurately shrink or enlarge parts to the same size they were before. Or is there a tool that will simply reverse a scaling automatically?
Steven, there is a function on your calculator called "Reciprocal" (Should look like 1/x) ... This function will give you the inverse of your scale. For example: the reciprocal value of .75 is 1.33333333~ not 1.25.
Secondarily, we use scale on most of our product and do a lot of work within configurations. This way we can have our base part with no scale at the size the customer wants. We then either add or subtract scaling based on the material we're using but do this in the "configuration" tab so that our base part is always considered the master part.
