parting sizes

Hi Michael,
I ran into an issue I could not quite understand.. I will send you the model to look at. I couldnt find anything skewed in the model and dont understand well the numbers I am seeing.

I have a block sized out with a parting line down the center in X... If I cut it, it is equal.. If I perform a boolean diff of some objects, then cut it, the sides are displayed as not equal.



In this model, there are named objects to direct you in which should do what.. The model is also scaled up by 10 (with a result scaled back down by .1 in style blue) the scaled down model shows the proper size, but with more decimal places, can see different numbers..

The parts come into my cam package as different sized halves. I got a working model by continually performing a shrink trimmed srf through the process, then using a sat export (to get both top edges of the parted model to display as "Z = 0")

Is this just me showing too many decimals past a tolerance point?? I did have to jump through a few hoops to get a working model (2 halves that appear equal in Z).

Not sure if this model iteration has had a few of the shrinks performed, but a simple boolean diff of the objects, then a half part of the block, will show 2 different sized halves in the object properties..

Email sent.
