If a pathway of extruding has branching, the pathway cannot be extruded one sweep operation. You can sweep while changing the cross-sectional shape (It is usualy called "Sweep Blend") by using multiple cross-sectional shapes. In following figure, a regular pentagon has been extruded along with a spiral that has been created with Creating primitives in Part workbench. Click Done to finish selecting.Īfter selecting the pathway, check Create solid at bottom left of the dialog and click OK on Sweep dialog to create a solid by sweeping.Īny cross-sectional shape can be extruded along the curve with this sweep method.
If you want to select more than one line, select lines with pressing Ctrl key. Then click Sweep Path and select a pathway of extruding in 3D View. Īt first, select a cross-sectional shape (Sketch001) and click ⇨ to set the cross-sectional shape as sweep-target. After that, click Close at Tasks tab in Combo View to exit sketch editing mode.įollowing figure shows the two sketches that has been created above steps. Match the center of the circle to the sketch plane origin with point-on-point constraint. The planes that will be used to create the cross sections are indicated in the 3D view, and will be updated based on the task panel inputs. Select the Meshes Cutting Cross-sections. You can set positions in rough because these will be adjusts in the restraint operation. There are several ways to invoke the command: Press the Mesh CrossSections button. Creates sketch planeĬreate a circle as shown in following figure. Select the document in Tree View and create new sketch plane on YZ-plane. to define a cross-section through a body ) either by simply cutting the. Next we create cross-sectional shape to be extruded. 360 Tangent constraint - FreeCADs form of Collinear Constraint Equal - Make. After that, click Close at Tasks tab in Combo View to exit sketch editing mode. When you say rotational symmetry - most ToolBits, at least the ones I constructed back when, are made by drawing (half) the cross section and then rotating. Match the endpoints of the sketch to the sketch plane origin with point-on-point constraint.
#FREECAD CROSS SECTION INSTALL#
Use To run the macro, first download it from this site and install it in your macros directory, then use the menu to call up your list of macros and double-click on this one. And exit polyline mode with mouse right click. Description Macro to display a cross-section of the objects in the scene: the cross-section plane can be moved by a slider bar. In polyline mode, you can draw arc with keybord M key. Select polyline and draw sketch as follow. This curve is used as pathway of extruding.Ĭreate new sketch plane on XY-plane. Following shapes can be created by this method.įirst we create a curve.
#FREECAD CROSS SECTION HOW TO#
In this example, we explain how to create a solid by extruding a cross-sectional shape along the curve.
