Parameter Calculated Value

[kieran_fawcett3Q9LP]

Hi 

im looking at making a parameter to calculate the Bottom of Hole on a Builders Work Hole

i have parameter for elevation from level, Hole Height and Half Hole Height (BOH)

My parameter needs to show Calculation for Elevation from Level Minus Half Hole Height (BOH)

But when i try to calculated Value i get Inconsistent Units

Is your BOH parameter of type "Length" and have units of millimetres, or is it just a number?

If it just a number then you would multiply it by 1mm so that you are subtracting millimetres from millimetres to get a result in millimetres:

Elevation from Level - (BOH*1mm)
