This is about the variable "NxWriteEcadTolerance" in the 'pcbx_ug_model.ini' file
What is the unit of this variable NxWriteEcadTolerance = 0.0001?
Solution
Most of the variables in the ini files are in meters however, there are a few exceptions, namely the tolerances, which are "unitless". We use the values as is so if NxWriteEcadTolerance= 0.0001 and the NX model is in mm, it will be 0.0001mm. If the NX model is in inches, it will be 0.0001in.
