If you select only the edge that is the arc, FreeCAD will extrude it, also with default settings. The observant will say that an arc has a normal (direction), this is true. Since from our second attempt we know that it worked when providing a direction, the error simply comes from trying to extrude a line without knowing a direction. In the first case we got an error that the direction could not be determined. Let’s go through why none of these ways are working. The actual selection happens when the left mouse button is released, and there is no preview of what will be selected.Įverything disappeared, clearly that did not work either. 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.
#Freecad extrude part of a sketch how to
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. 7 Making a sketch out of the 2D profile.
