Introducción

Geometría sólida constructiva (CSG) es un paradigma de modelización que se utiliza en muchos sistemas tradicionales de CAD. Consiste esencialmente en utilizar objetos sólidos primitivos y hacer operaciones booleanas con ellos, como la fusión, la sustracción y la intersección, para crear una forma final.

In FreeCAD, this method is mostly utilized with the Part Workbench, which has the ability of creating primitive objects like boxes, cylinders, and spheres and fuse them together, or use them to cut other objects with tools like Part Cut.

Constructive solid geometry (CSG) workflow; any number of operations can be done on solid primitives to create other solid objects, and then fuse or cut them until the final shape is produced.

Alternatively, the PartDesign Workbench uses a more modern approach than simple CSG; this method is called feature editing, which means creating a base solid, and then adding sequential parametric transformations to obtain a final body.

Note: A PartDesign Body created with the PartDesign Workbench can also be used in a boolean operation with other objects.

Ejemplo

Ejemplo de flujo de trabajo de geometría sólida constructiva (CSG): se fusionan partes primitivas (unión); se calcula la intersección de otras dos partes primitivas (común); se obtiene la diferencia (corte) de las dos formas anteriores.

Tutoriales

The tutorials page provides some examples on creating solids with the Part Workbench that use the CSG method.
