Example 3: Lightning Protection

This document shows an example to create a model of lightning protection for a radome:

1. Define two vertical segments close to the external radome surface.

   
   

   

   
   Figure 1. Two vertical segments close to the external radome surface

2. Project one segment to the closest external surface.

   
   

   

   
   Figure 2. Project one segment

3. Select the surface.

8. Define a radome.
   Note: The lightning strip protection is external to the radome.
