Area/CentroidKeyCreator \ Verify \ Area-Centroid
Use the Area/Centroid option to measure the area of a selected closed figure. The centroid's X and Y coordinates will be displayed. The area of a selected closed figure is calculated, along with the X and Y coordinates of the centroid. A centroid is the center of mass in an object. For a typical closed figure, rectangles are used, called panels, to estimate the area of the selected shape. You can control the width of these panels for more accuracy; smaller panel widths give more accurate calculations. Note that this function only works for Wireframe entities.
When verifying the area and centroid, keep these things in mind:
n The information is calculated using the current cplane coordinate system, XV, YV, and displays a temporary marker.
n Selected entity data information is always projected to the current cplane before it finds the area or centroid.
Using the Function:
1 Select Area/Centroid from the Tools>Verify submenu.
2 Select the entity(s) to be verified using the selection menu, then select ACCEPT when done.
3 Input a panel interval. The rectangular shapes, called panels, approximate the area used to calculate the area/centroid of the shape you select. The Data Verify box will then display the area/centroid data of the selected entity(s).
