The current "0.99999" precision level for physical properties provides adequate accuracy for PARTsolutions software needs (particularly volume unit conversion), however, for certain NX models the calculation of these properties takes an extremely long time.

The key "PhysicalPropertiesPrecision" offers the possibility to reduce the accuracy to an acceptable level (NX UI default is 0.99).

Default value is "0.99999", meaning the physical property precision is five decimal places. The user can now change this precision by adding or removing the "9"s in the string. A precision of "0.99" offers a "good enough" approximation and speeds up the calculation dramatically.
