Directly importing from CAD model is supported (although we didn’t use it).

Booleans operations (Union, Intersection and Difference) are usually useful, especially the models with absorbing boundary condition (the environment is obtained by differentiating the antenna from a sphere) or holes.

Warning❗️❗️❗️

1. Remember to select the unit!

   Selection of the unit can be found at the settings of Comp1 → Geometry1.

2. When building more than one objects, remember to check their relative positions.

   The Bases of some objects are at their geometric centre, some are at corners.

   Their position can be set at the settings of Comp1 → Geometry1.

3. When using Booleans, you can choose Keep objects to add or Keep objects to subtract.
