| Calculation mode | - Exact else approximate: Measures exact data and gives true values. If exact values cannot be measured, approximate values are calculated (identified by a ~ sign).
- Exact: Measures exact data and gives true values.
- Approximate: Measurements are done on tessellated objects and approximate values are calculated (identified by a ~ sign).

| Selection |
Select a geometric element to measure. You can refine your selection by
selecting the required geometry type in the Selection mode
box. |
| Associative if possible |
Select this check box to make the measure associative with the
geometry. |
| Axis System | Select this check box to perform the measurements with respect to an axis system other than the global axis system. You can either select an axis system in the work area or define an axis system by selecting two edges on the geometry. |

| Keep Measure | Select this check box to make the measurement persistent. |

| Second moment of area at COG along XY | For surfaces, select this check box to compute the second moment of area values along x and y axes. |
