Have you ever had the issue, that you wanted a sum of several fields, but wanted Acad to use the rounded numbers not the real accuracy?
eg. we want to add up areas for a flat, and since you only have to have an accuracy of 1,01m2 (eg.) but we are drawing in cm, Acad uses 1.0050m2 in the back to calculate. most of the times that might not have an effect, but if it does it might actually be quite grave (buying a flat...)
thanks for any answer.
