Guidelines
Consider the following guidelines when using the Measure tools:
■
When you measure an object, the position at which you select the object determines the
measurement of the object.
■
If you use multiple points, a running total of the distance based on existing line segments and the
current rubber band line is calculated.
■
The Measuregeom command cannot calculate the area of a self-intersecting object.
■
With the Area tool you may turn on the Add or Subtract mode and either keep a running total of
area as you define areas or subtract a specified area from the total area.
■
With the Volume tool you may turn on the Add or Subtract mode and either keep a running total
of volume as you define regions or subtract a specified region from the total volume.
■
When using the Volume tool, you may select 3D solids or 2D objects. However, if you select a 2D
object you must specify a height for that object.
■
You can select polylines when using the Distance, Area, and Volume options.
