Introduction

In FreeCAD the word "Drawing" is normally used to refer to a 2D projection of a 3D model. This is usually created with the TechDraw Workbench.

Usage

1. Start with an already built 3D model, created with, for example, the PartDesign Workbench. In fact, any object that has a Shape, including 2D objects, will work.
2. Switch to the TechDraw Workbench.
3. Press TechDraw PageDefault or TechDraw PageTemplate to create a Page.
4. Select the existing model, and then press TechDraw View.
5. A 2D projection on the page will be created. You may now adjust its properties, like DataScale, DataRotation, and DataDirection.
6. When the drawing is ready, you can press TechDraw ExportPageSVG or TechDraw ExportPageDXF, or use Std Export, to export the page to SVG, DXF, or PDF formats for further use in another software, or for printing.

Notes

In informal usage, a "Drawing" may be any geometrical figure that is visible in the 3D View, and thus its concept may be confused with that of "Body", "Part", or "model".

However, when more precision is required, the distinction must be made.

• A "Body" (PartDesign Body) is an object derived from a Part Feature (Part::Feature class), created with the PartDesign Workbench.
• A "Part" (App Part) is used to group several "Bodies" to form an assembly.
• A "Drawing" is a 2D projection of a "Body" or a "Part".
