Draft tutorial

Introduction
This tutorial is meant to introduce the reader to the basic workflow of the Draft Workbench.

The reader will practice:
 * creation of profiles
 * the use of working planes
 * the creation of dimensions, text and annotations

This tutorial uses the notation to denote the coordinates required to define points in an object.



Setup
1. Open FreeCAD, create a new empty document with.
 * 1.1. Switch to the Draft Workbench from the workbench selector, or the menu.
 * 1.2. Make sure you understand how to use the property editor, particularly the and  tabs to change the properties.
 * 1.3. Since the draft objects are planar shapes, they are better viewed from the top. Use to set the 3D view.

Snap toolbar
2. The Draft Snap toolbar is normally activated when you switch to the Draft Workbench.
 * 2.1. To make sure it is always there, got to the Draft Preferences,.
 * 2.2. Verify that the Show Draft Snap toolbar is active.

You can also change the visibility and property of the grid in this same menu.

Working planes
Most Draft objects are planar shapes so they are naturally based on a. A working plane can be one of the main XY, XZ, and YZ global coordinate planes, or it can be a plane that is parallel to them with a positive or negative offset, or it can be a plane defined by the face of a solid object.

3. Press Select plane, or go to the menu, to open the working plane task panel.
 * 3.1. Press.

Before pressing the button, you can also change the value of the offset in millimeters, as well as the grid spacing, the main lines and snapping radius.

Creating Profiles
The creation of profiles can be done in several ways. Though it is possible to use simple arcs and lines to do most of the work, FreeCAD includes several tools to speed up the process.

Lines and arcs
4. We will create arcs and lines.
 * 4.1. Press.
 * 4.2. Set the to, and press.
 * 4.3. Set the to, and press.
 * 4.4. Set the to, and press.
 * 4.5. Set the to, and press.
 * 4.6. Repeat the same procedure for a second arc with a radius of, the other properties are the same.

5. We will now create a closed profile by tying the arcs with lines.
 * 5.1. Press.
 * 5.2. In the Snap toolbar make sure is active, and only  as well. As you move the pointer to one endpoint of an arc, the Snap_Endpoint.svg Endpoint icon should appear. Click to select this point.
 * 5.3. Move the pointer to the closest endpoint of the other arc in the same side to tie the two arcs together.
 * 5.4. Repeat the process for the other side of the arc to close the profile.

Fusing or upgrading
We now have several objects in the tree view that form a closed profile. However, this profile is still composed of disconnected objects; each of them can be edited and moved independently of the others. It is possible to continue working with the elements in this way, but it is also possible to fuse them into a single object.

6a. Note that fusing the objects into a single object will create an object that is no longer parametric, so their properties cannot be modified further.
 * 6.1. Select all four objects by holding and picking on them in the 3D view or by selecting them in the tree view.
 * 6.2. With these objects selected, click on.
 * 6.3. This will upgrade the four objects into a single.

6b. If you wish to maintain the parametric nature of the objects you may wish to create a compound instead.
 * 6.1. Switch to the Part Workbench.
 * 6.2. With these objects selected, click on.

Rectangles, circles, and polygons
7. We will draw a rectangular frame.
 * 7.1. Press.
 * 7.2. Enter the values, and press.
 * 7.3. Make sure the option is unchecked, as we will use absolute units. You may press  in the keyboard to quickly toggle this option on and off.
 * 7.4. Enter the values for the second point, and press.

A rectangle is created. Go in the property editor to change its properties. If you don't want the rectangle to create a face, set to. If you want to make a face, but see only the wires of that object, keep to  but set the  to.

8. We will draw a circle.
 * 8.1. Press.
 * 8.2. Enter the values of the center, and press.
 * 8.3. Set the radius to, and press.

9. We will draw a regular polygon.
 * 9.1. Press.
 * 9.2. Enter the values of the center, and press.
 * 9.3. Set the number of sides to, and press.
 * 9.4. Set the radius to, and press.

Again, you may change the and  properties in the property editor if you want.

The rectangle, the circle, the polygon, and most other objects created with the Draft Workbench share many data and view properties because they are derived from the same base class, Part Part2DObject.

Arrays
Arrays are used to replicate an object several times in an orthogonal direction (X, Y, Z), around a revolution axis, or along a path.

10. We will create a polar array.
 * 10.1. Select the object that was previously created with the  tool, or the  created with the  tool.
 * 10.2. Press.
 * 10.3. Adjust the polar angle to, and press.

Old workflow

 * 10.2. Press.
 * 10.3. Go to the tree view, select the object, and then go to the property editor, and change the  from  to.
 * 10.4. Change to, and  to.

An array object should be created replicating the object around the origin.

Dimensions
Linear dimensions work best when using the appropriate Draft Snap methods to select points and edges to measure. However, they can also be created by specifying absolute coordinates.

11. Create dimensions for the different objects.
 * 11.1. Press.
 * 11.2. Pick the first point. In this tutorial the first point will always be the origin.
 * 11.3. In the Snap toolbar make sure is active, and only  as well. As you move the pointer to the top edge of the polygon, the Draft_Midpoint.svg Midpoint icon should appear; click to select this point.
 * 11.4. Move the cursor to the right to specify the location of the dimension, the click to set the final position, around . The dimension will automatically show the length value measured between the two points.
 * 11.5. Select the dimension object in the tree view, and in the property editor, change to, set  to , and  to.

12. Repeat the process for the two arcs of the closed profile. The first point of the measurement will still be the origin, and the second point will use the Midpoint of the arc.

13. Repeat the process for the circle located in the center. The first point of the measurement will still be the origin. To select the second point make sure is active, and only  as well. As you move the pointer to the top of the circle, the Angle icon should appear; click to select this point. Then move the cursor to the right and click to fix the dimension.

Remember to adjust the, and other properties to see the dimension correctly.

Texts and ShapeStrings
14. Text objects are simple planar figures that are created in the 3D view but don't have an actual shape underneath. This means that they cannot be used in complex operations with shapes, such as extrusions or boolean operations.
 * 14.1. Press.
 * 14.2. Select the reference point in the 3D view. In the Snap toolbar make sure is active, and only  as well. Move the pointer to the top edge of the highest arc, so that the Draft_Midpoint.svg Midpoint icon appears; click to select this point.
 * 14.3. Enter the desired, and press once to start a new line; then add more text as required.
 * 14.4. When you are ready to finish with edition, press twice.
 * 14.5. Select the text object in the tree view, and in the property editor, change to, and  to.

15. ShapeString objects are shapes made of primitive wires that follow the lines indicated by a certain font. This means that these objects have a real shape underneath and thus can be used in complex operations like extrusions and boolean operations.
 * 15.1. Press.
 * 15.2. Move the pointer to the desired location in the 3D view above the regular polygon, and click once. This will set the coordinates of the shapestring. This may be entered manually as well, for example,.
 * 15.3. Enter the desired, and choose the desired.
 * 15.4. If there is no default font file, you must click on the ellipsis to open the dialog to navigate to a font location.
 * 15.5. When a valid font file is specified, press.

Creating blueprints
As it is now, the objects that we have created can be saved, exported to other formats like SVG or DXF, or printed.

If you wish, you may create a technical drawing to display these objects together with additional information like a frame.

Before doing anything, hide the Draft grid by pressing.

16. Switch to the TechDraw Workbench.
 * 16.1. Create a standard page by pressing.
 * 16.2. In the tree view select all objects created, except for the Page, and then press ; press with the default options.
 * 16.3. Select the Page object in the tree view to show the Page in the 3D view. Go to the property editor, and change to.
 * 16.4. Expand the Page object in the tree view to select the ActiveView object. Go to the property editor, and change to.
 * 16.5. Recompute the model by using or pressing.

TechDraw works best with objects that have a Part TopoShape. Since some objects from Draft, like Draft Texts and Draft Dimensions, don't have such "Shapes", some operations of TechDraw don't work with these elements.

Tools like, , and work by receiving an internal SVG image that is generated by internal Draft functions; therefore, TechDraw doesn't have much control about how these views are displayed. More integration of Draft and TechDraw is a work in progress.
