When your model cannot exist printed or milled straight by a machine, for example it is too large (a edifice) or it requires transmission assembly after the pieces are ready, you lot will normally need to explain to another person how to practice it. In technical fields (engineering, architecture, etc), this is usually washed with drawings. The drawings are handed over to the person responsible for assembling the final product and will explicate how to do information technology.

Typical examples are Ikea instructions, architectural drawings, and blueprints. These drawings normally contain not only the drawing itself, but as well many annotations, such as text, dimensions, numbers, and symbols that will help other people to understand what needs to be done and how.

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

The TechDraw Workbench allows you to create sheets, which can be bare or apply a pre-made template to already have a series 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 canvas. You lot tin likewise place all kinds of annotations on the sheet, such as dimensions, texts, and other symbols usually used in technical drawings.

Drawing sheets, one time complete, tin be printed or exported as SVG, PDF or DXF files.

In the post-obit exercise, we will encounter how to create a elementary drawing of a chair model institute in the FreeCAD library (Furniture → Chairs → IkeaLikeChair). The FreeCAD library tin can easily be added to your FreeCAD installation (refer to the installing affiliate of this transmission), or you can just download the model from the library webpage, or via the directly link provided at the bottom of this chapter.

• Load the IkeaLikeChair file from the library. You can cull between the .FCStd version, which will load the full modeling history, or the .footstep version, which will create simply one object, without the history. Since nosotros won't need to model whatsoever further now, information technology is best to choose the .step version, equally it will exist easier to dispense.

• Let's repeat the operation twice, to create two more views. We will gear up their Ten and Y values, which indicate the position of the view on the page, in order to prove them autonomously from the peak view, and their direction, to create unlike view orientations. Give each new view the following properties:
  • View001 (forepart view): 10: 70, Y: 220, Scale: 0.i, Rotation: 0, Direction: (-1,0,0), XDirection: (0,-ane,0)
  • View002 (side view): Ten: 150, Y: 220, Scale: 0.1, Rotation: 0, Direction: (0,-i,0), XDirection: (1,0,0)
• After that, we obtain the following folio:

• We can tweak the aspect of our views if nosotros want, for instance nosotros can modify their Line Width belongings (under the View tab in the Philharmonic View) to 0.five.

We will at present place dimensions and indications on our drawing. There are 2 ways to add together dimensions to a model: one is placing the dimensions inside the 3D model, using the Dimension tool of the Typhoon Workbench, and so placing a view of these dimensions on our sheet with the TechDraw DraftView tool. The other is to exercise things directly on the TechDraw sheet. We'll use the latter method.

• We volition now identify the two callouts shown in the image higher up, using the TechDraw Balloon tool.

1. Looking at the Page in the 3D view window, select the View to which the Airship volition be attached, as shown in the image above.
2. Press the Airship button.
3. The cursor is at present displayed as a airship icon. Click on the page to place the balloon origin at the desired position.
4. The balloon bubble may be dragged to the desired position.
5. Change the balloon properties by double clicking the balloon label or the balloon object in the tree view. This volition open the Balloon Job dialog. Prepare the Value field to the desired text and alter the Symbol drop-down bill of fare selection to None
6. Press OK
7. Echo the operation for the second callout.

• We will now fill in the sheet championship cake.
  • Make sure that the View frames, labels, and vertices are visible. If not, hit the Toggle button.
  • Edit the text in each section of the sail 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 farther piece of work in graphical applications like Inkscape or to DXF. Select the page in the tree view and then select bill of fare File → Export. The DXF format is importable in nearly all existing 2d CAD applications. TechDraw pages can besides be directly printed or exported to PDF.
