Hello,

I'm using an equation to drive a sketch dimension that will sometimes be 0". When the equation evaluates to 0", I get the following error message:

"The equations evaluates to a value that lies outside the modeler resolution."

Is this for real? Can I not have a value of 0" for a distance dimension and drive it with an equation?

For context, the value I'm driving is the pitch height of a part above the top plane, which will sometime be zeroed out and sometimes have a positive value:

I'm not really looking for an alternative solution here; I just want to know if you truly cannot drive a part dimension with equations if it's going to be zeroed out. This will come up again and again in my industry.

Thanks,

Bob

I wouldn't want it too, because SW has been known to flip dimensions and then you'll end up with a negative number instead. Not sure of where you're getting the dimensions from, but what I would do is either offset a Plane by a small amount or add a sketch line that hangs out over and dimension from either of those options, that way your dimension never goes to Zero and therefore no chance of the dimension being stuck or flipping..
