![]() :-)įor now I will close this ticket, I/we can reopen it after a discussion on the Help forum, if needed. Please post on the Help forum with details about what you are trying to achieve and we will be able to help you resolve the matter. ![]() Trying to do so sounds like just mistaken modelling practice. Trying to extrude from a mixed source creates a potentially undefined situation that should not work and does not work. Mixtures of the above should only be made with separate extrudes. If you Part Workbench extrudeģ) an open wire (series of connected lines) you get an open shell (series of connected faces)Ĥ) a closed profile wire you get a closed shell with the option to convert it into a solid :-)īriefly though the output is logical and hierarchical. If you would like to post on the Help forum I and others will be happy to explain in detail. This way many people see, have an input and possibly learn from the one post. menu (see Construction tools) mini-shelf creation extrude tool, 244 merge function. Please discuss all bugs and feature requests on the Help forum first, no matter how sure you are that it is a bug and only create a ticket after others have confirmed its a bug. Shoe draw tool, 290291 flatten tool, 289 grab tool, 288 Sintering. So the Sketch Origin is at the Body XYOrigin. The sketch I will be using is currently Mapped to the XYPlane. Click Close on Task tab to exit sketch editing mode. Switch the view of the key fob to edge on. You need to recreate the face first and then use standart extrude. What you appear to be asking for can not and should not work. To Map a Sketch to a Face begin by selecting the Face. But what fun is that the keyfob as a slab before angling the surface and adding text Sketching the Slope If we turn the back end of the key fob into a sloping surface we save plastic and we can then put angled text onto the sloping face. This is not a bug, it appears to be just a failing to understand how FreeCAD and OCC work. The property of a solid is that every edge is shared by exactly two faces so that the whole object is watertight. This is because the actual result you expect is not a solid. But the result still might be different to what you expect because it removes the edges. Now when extruding the sketch with the solid option you get a filled shape. To get a closed wire you must break the top and bottom lines so that there is a vertex in between and the fourth line must be connected to this two vertexes. So, the algorithm only finds the "C" as wire which of course is not closed and thus creating a face is not possible. In your example the three lines build a "C" and the fourth line starts and ends at the two horizontal lines of the "C" but there are no vertexes. However, the problem is already that there is no closed wire - at least not in topologically correct way. I am looking for a solution that will work for both GUI and python standalone. However, you cannot do this with python alone. I have succesfully extruded a face using the Draft workbench and the trim tool. In order to make a solid the algorithm first must find a closed wire where it can create a face from. xbit Posts: 140 Joined: Mon 10:48 am Extruding a face by xbit Wed 3:57 pm I want help with extruding a face. This is not a bug because what you want to achieve is simply not possible. Revolution operation results are as follows.> Freecad can't extrude an R like sketch into a solid. Edge of exisiting shape (select by click on 3D view).Construction line in the sketch (select by click on 3D view).Select New Sketch in toolbar and select XY plane as sketch plane on the dialog. Rotation axis can be selected from followings. Create new document and switch workbench to Part Design workbench. Enter angle of rotation on the dialog and click OK. Select the created sketch model tree and execute Revolution to execute rotation extruding. Apply constraints to the sketchĬlick Close on Task tab to exit sketch editing mode. In this operation, we use Horizonal constraint, Vertical constraint, Vertical Distance constraint, Horizontal Distance constraint, Equal Length constraint and other constraints. Select each segment of line and apply constraints as shown in following figure. Applies Coincident constraint to the end points Select two end points and select Coincident constraint in toolbar to connnect the lines. Select Polyline in toolbar and draw a "H" shape on the sketch plane as shown in the following figure. Create new document and switch workbench to Part Design workbench.
