When your model cannot exist printed or milled directly by a car, for case it is too large (a building) or it requires manual assembly after the pieces are ready, you volition unremarkably need to explicate to another person how to do it. In technical fields (engineering, compages, etc), this is usually done with drawings. The drawings are handed over to the person responsible for assembling the final product and will explicate how to exercise information technology.

Typical examples are Ikea instructions, architectural drawings, and blueprints. These drawings commonly contain non just the drawing itself, but also many annotations, such as text, dimensions, numbers, and symbols that will assist other people to empathize what needs to exist done and how.

In FreeCAD, the workbench responsible for making such drawings is the TechDraw Workbench.

The TechDraw Workbench allows yous to create sheets, which can exist blank or use a pre-made template to already have a serial of items on the sheet, such as borders and a championship. On these sheets, you can then identify views of the 3D objects you modeled previously, and configure how these views will appear on the sheet. Y'all tin as well place all kinds of annotations on the sheet, such as dimensions, texts, and other symbols ordinarily used in technical drawings.

Drawing sheets, once complete, can be printed or exported as SVG, PDF or DXF files.

In the post-obit exercise, nosotros will meet how to create a simple drawing of a chair model plant in the FreeCAD library (Piece of furniture → Chairs → IkeaLikeChair). The FreeCAD library can easily be added to your FreeCAD installation (refer to the installing chapter of this manual), or y'all can simply download the model from the library webpage, or via the direct link provided at the bottom of this chapter.

• Load the IkeaLikeChair file from the library. You can cull between the .FCStd version, which volition load the total modeling history, or the .step version, which will create just ane object, without the history. Since we won't need to model any further at present, it is all-time to choose the .footstep version, as it will be easier to dispense.

• Let'southward repeat the operation twice, to create ii more views. We volition set their Ten and Y values, which indicate the position of the view on the page, in order to show them apart from the summit view, and their direction, to create different view orientations. Give each new view the following properties:
  • View001 (front view): 10: seventy, Y: 220, Calibration: 0.1, Rotation: 0, Management: (-1,0,0), XDirection: (0,-i,0)
  • View002 (side view): 10: 150, Y: 220, Scale: 0.i, Rotation: 0, Direction: (0,-1,0), XDirection: (1,0,0)
• After that, we obtain the post-obit folio:

• Nosotros tin tweak the attribute of our views if we want, for example we tin can modify their Line Width holding (under the View tab in the Combo View) to 0.v.

Nosotros volition now place dimensions and indications on our drawing. In that location are two ways to add together dimensions to a model: ane is placing the dimensions inside the 3D model, using the Dimension tool of the Draft Workbench, then placing a view of these dimensions on our canvas with the TechDraw DraftView tool. The other is to do things directly on the TechDraw sheet. We'll use the latter method.

• We volition at present place the two callouts shown in the image in a higher place, using the TechDraw Balloon tool.

1. Looking at the Page in the 3D view window, select the View to which the Airship will be attached, as shown in the prototype above.
2. Printing the Balloon push.
3. The cursor is now displayed as a balloon icon. Click on the folio to identify the balloon origin at the desired position.
4. The airship bubble may be dragged to the desired position.
5. Alter the balloon backdrop past double clicking the balloon label or the balloon object in the tree view. This will open the Balloon Task dialog. Ready the Value field to the desired text and change the Symbol drib-downward menu selection to None
6. Press OK
7. Repeat the performance for the second callout.

• Nosotros will at present fill up in the canvas title cake.
  • Brand sure that the View frames, labels, and vertices are visible. If not, hit the Toggle push.
  • Edit the text in each section of the canvass title block by clicking on the small green square on the left side of the text.

Our page tin now be exported to SVG for further piece of work in graphical applications like Inkscape or to DXF. Select the page in the tree view and then select card File → Consign. The DXF format is importable in most all existing 2D CAD applications. TechDraw pages can also be direct printed or exported to PDF.
