Draft

Popis

Top: a Draft Wire extended and then trimmed.
Bottom: a face extruded into a solid body.

Trim or extend

Usage

Options

The single character keyboard shortcuts available in the task panel can be changed. See Draft Preferences. The shortcuts mentioned here are the default shortcuts.

• Hold down Alt to invert the default result of the command.
• Hold down Shift to restrict the operation to the current segment of a Draft Wire.
• Press S to switch Draft snapping on or off.

Here is an example to explain the modifier keys. The left edge or the bottom edge of the U-shaped wire was extended. All Draft Snaps were turned off.

Extrude

Usage

See also: Draft Snap and Draft Constrain.

1. It can be helpful to first change the Draft working plane so that it is not coplanar with the face you want to extrude.
2. Optionally select a single face or an object with a single face.
3. There are several ways to invoke the command:
   • Press the Draft Trimex button.
   • Select the Modification → Trimex option from the menu.
   • Use the keyboard shortcut: T then R.
4. If you have not yet selected an object or a face: select an object with a single face in the 3D View.
5. The Trimex task panel opens. See Options for more information.
6. To define the extrusion direction and distance do one of the following:
   • Pick a point in the 3D View that does no lie on the same plane as the face.
   • Make sure the pointer is on the correct side of the face in the 3D View and enter a Distance.

Options

The modifier key mentioned here can be changed. See Draft Preferences.

• Hold Shift to extrude in a direction that is not parallel to the normal of the face.

Scripting

extrusion = extrude(obj, vector, solid=False)

• obj is the object to be extruded.
• vector is the extrusion direction and distance.
• If solid is True a solid is created instead of a shell.
• extrusion is returned with the created object.

Example:

import FreeCAD as App
import Draft

doc = App.newDocument()

rectangle = Draft.make_rectangle(1500, 500)
doc.recompute()

vector = App.Vector(0, 0, 300)
solid = Draft.extrude(rectangle, vector, solid=True)
doc.recompute()
