Draft Workbench/pt-br

Introdução
A  bancada de trabalho Draft permite desenhar objetos 2D simples, e oferece várias ferramentas para modificá-los posteriormente. Ele também fornece ferramentas para definir um plano de trabalho, uma grade e um sistema de disparo para controlar com precisão a posição de sua geometria.

Os objetos 2D criados podem ser usados para esboço geral de uma forma semelhante à do Inkscape ou do Autocad. Estas formas 2D também podem ser usadas como componentes base de objetos 3D criados com outras bancadas de trabalho, por exemplo, a bancada de trabalho Part e Arch. A conversão de objetos de Draft para Sketches também é possível, o que significa que as formas também podem ser usadas com a  bancada de trabalho PartDesign para a criação de corpos sólidos.

The Draft Workbench also provides tools to define a working plane, a grid, and a snapping system to precisely control the position of geometry.

O FreeCAD é principalmente uma aplicação de modelagem 3D, e assim suas ferramentas 2D não são tão avançadas como em outros programas de desenho. Se seu objetivo principal é a produção de desenhos 2D complexos e arquivos DXF, e você não precisa de modelagem 3D, talvez você queira considerar um programa de software dedicado ao desenho técnico, como o LibreCAD, QCad, ou outros.

Testes unitários
Bancada de trabalho Testing framework.

Para executar os testes unitários da bancada de trabalho, executar o seguinte a partir do terminal do sistema operacional.

Scripting
As ferramentas Draft podem ser usadas em macros e do console Python usando o Draft API.

A bancada de trabalho inclui um módulo para criar amostras de todos os objetos em um novo documento.

Use isto para testar se todos os objetos são produzidos corretamente.

A inspeção do código deste módulo é útil para entender como utilizar a interface de programação.
