Let us begin with the position, which is on coordinate (50, 50, 0). ![]() To make the chamfer we need to have a line with the correct inclination and also be able to position it correctly. The Fillet is created and your model should now look like below. Check Delete original objects and change the radius to 20 mm and hit enter. With the top right corner edges selected, invoke the command Fillet in the Draft Workbench. The actual selection happens when the left mouse button is released, and there is no preview of what will be selected. If one drags from left to right, only objects fully enclosed by the selection area are included in the resulting selection. When dragging from right to left the resulting selection includes everything fully or partially within the selection area. Start by selecting the upper right corner edges, use menu Edit → Box selection Box selection, hold down the Left Mouse Button and drag from right to left and release the LMB. It is now a Draft Workbench object where one can edit for example the start point and the end point through the Property editor, this is not possible with the edge objects. Select the left vertical edge and invoke the command Draft Upgrade, the former edge will now have a different icon and has changed label to Line. This blue box is the icon used for generic geometric objects (Part Workbench geometric objects to be specific, but that is for advanced readers). The observant will notice that the object icon in the Tree View already for the wire changed to a blue box. Invoking Draft Downgrade once more will break up the wire into its edges, shown in the middle picture below. Next we will break up the rectangle into its four edges, this is done by first selecting the Rectangle and then invoking the command Draft Downgrade, the filled face will disappear and the object in the Tree View is now a Wire instead of a Rectangle, shown in the left picture below. The Rectangle is finished and it should look like this after applying Fit all to the view. Make sure the created Rectangle is selected, then change the Position of the rectangle to (0, 0, 0), modify the height to 50 mm and the length to 100 mm as per the images below. This can be accomplished through the Property editor. The side view of our final model has the outer contour of 100 x 50 mm, and it would be nice if the lower left corner was placed in the global zero position. If you happened to have changed it, just change back to the Top view before starting any new command in the Draft Workbench. So, until the 2D profile is completed, it is best to simply keep the Top view (camera position) and not play around with rotating the view. That 2D plane is called the Working plane, and, if default settings are used, it will always automatically align itself to the current 3D view. When working in the Draft Workbench one almost always draws on a 2D plane. ![]() ![]() Your 3D view should now have a rectangle drawn, similar to the below picture. A task panel will open once the command is invoked, this time we are not going to use it at all, but you could of course enter the coordinates for the rectangle directly. To start off the profile, draw a random Rectangle on the xy-plane by clicking 2 points in the 3D view forming any diagonal of a rectangle. If the grid does not show, toggle it on/off with Toggle Grid. Change the view to Top view and switch to the Draft Workbench, your screen should look like below. The model to make Creating the 2D profileĬreate a new document and save it directly under a new name. The tutorial is composed such that the aim is not necessarily to show the most efficient way to use the program, but rather to make the reader aware of different functionalities available in FreeCAD, how to use them, and where to find them. This tutorial expects the user to be briefly familiar with both the user interface and some workflows available in FreeCAD. The reader is recommended to first work through the sister tutorial Creating a simple part with Part WB, which is creating the same model with a different technique, while at the same time covering more of the basics of FreeCAD’s user interface. ![]() The tutorial uses a 2D shape to create a 3D solid, the latter is accomplished through the Part Workbench. This tutorial aims to be used as a first introduction to the Draft Workbench in FreeCAD. Creating a simple part with Part WB, Creating a simple part with PartDesign ![]()
