How to calculate the surface area of a cross-section

Objective:

Calculate the surface area of a cross-section.

Procedure:

1. Section the Implicit Body

First, create the cross-section of your part.

  • Add a Section Body block.
    • In the Body input, insert the geometry you want to measure.
    • In the Plane input, define the sectioning plane. A Plane from Normal block is a common way to do this. You can use a list of Point inputs to create multiple planes.

2. Calculate the Surface Area

Next, measure the area of the cross-section you just created.

  • Add a Surface Area block.
    • Insert the Section Body block from the previous step into the Body input.

The calculated area is now available in the block's output.

  • You can see the calculated surface area value in the header of the Surface Area block's information panel.
  • If you select a list of planes, open the block's Properties panel to view a list of all the calculated surface area values.

And that’s it! You’ve successfully calculated the surface area of a cross-section in three simple steps.
