Part Module/es

Introducción
Las sólidas capacidades de modelado de FreeCAD se basan en la OpenCASCADE (OCCT), un sistema CAD de calidad profesional que presenta una creación y manipulación avanzada de geometría 3D. El Part Ambiente de trabajo es una capa que se encuentra en la parte superior de las bibliotecas de la OCCT, que da al usuario acceso a las primitivas y funciones geométricas de la OCCT. Esencialmente todas las funciones de dibujo 2D y 3D en cada banco de trabajo ( Draft, Sketcher, 24px PartDesign, etc.), se basan en estas funciones expuestas por el banco de trabajo de diseño de piezas. Por lo tanto, el Part Workbench se considera el componente central de las capacidades de modelado de FreeCAD.

The objects created with the Part Workbench are relatively simple; they are intended to be used with boolean operations (unions and cuts) in order to build more complex shapes. This modeling paradigm is known as the constructive solid geometry (CSG) workflow, and it was the traditional methodology used in early CAD systems. On the other hand, the PartDesign Workbench provides a more modern workflow to constructing shapes: it uses a parametrically defined sketch, that is extruded to form a basic solid body, which is then modified by parametric transformations (feature editing), until the final object is obtained.

Part objects are more complex than mesh objects created with the Mesh Workbench, as they permit more advanced operations like coherent boolean operations, modifications history, and parametric behaviour.
