OpenSCAD How-To - Using sections when designing parts

Note:
These parts are examples only.

When designing parts, it's very convenient to use sections.
Especially when designing parts that will be assembled.

For this, use the Boolean combination - difference or intersection.

You can also slightly shift the section objects to ensure that the assembled parts don't intersect.

I also recommend using the color command.
Then the section cut will have the color of the cutting primitive.

Using the $preview variable, you can control the creation of a part.
In view mode (F5) - section of the part
In rendering mode (F6) - the whole part.

Download the OpenSCAD script, study the example, and use these techniques in your designs.
