• Measure >> Distance >> Perimeter >> Point / Ref. Plane command measures the perimeter of a section cut by the plane parallel to a selected reference plane at a point on a shell specified by user.

Step   

Execute Measure >> Distance >> Perimeter >> Point / Ref. Plane command as follows:

1. Select Measure >> Distance >> Perimeter >> Point / Ref. Plane from the menu or click the icon from the Measure toolbar.

2. Select a reference plane to cut the shell.

3. Select a point or a reference point where the shell is cut.

If a user clicks the right mouse button, the following pop-up menu appears.

Select Ref. Point to pick a reference point instead of a point on shells.

4. The result appears on the lower left side of the workspace window as follows.

Perimeter is the length around the section.

Area is the area of the section.

Centroid is the coordinate of the centroid of the section. It is represented as an red sphere.

When the cross section does not form a closed path, Area and Centroid can not be calculated and Open Section is shown on the screen instead.

• This menu is disabled if there is no reference plane.
