![]() SOLID: in the Shape Content, should match the number of objects Select the newly created CompoundFilter from the object tree andĬlick Check Geometry (Part → Check Geometry). Keep BooleanFragments selected and then apply a Compound Filter to Select the newly created BooleanFragments in the object tree andĬhange its Mode property to CompSolid, see the figure below. In the Part workbench, select all objects and create Booleanįragments (Part → Split → Boolean Fragments) Open a new project and merge all objects, i.e. (2) The trick then lies in merging these shapes into a singleĬompsolid. ![]() The sandĬhannel is a simple cube, created in the Part workbench. FCStd FreeCAD files and playing around with them. You can also have a look at how these geometries See the Inversion-Region in the object tree In the Part Design workbench, by making a sketch and then extruding (1) The outer and inversion regions of this dike example were created Meaning one object that consists of multiple solids that Merge all regions into one single ”compsolid”, i.e.composite To get familiar with the part design workbench, this Workbench, or in the Part Design workbench for more complicated The geometries are defined in three steps:Įach region of the geometry designed separately in the Part Regions: the outer region and the inversion region. Outer region the inner region (same as inversion region in thisĮxample) and the sand channel. The modeling geometry consists of three regions: the Therefore, the mesh itself would act as prior information The geometry of the sand channel is alreadyincluded in the structure When the same meshes are used for modeling and inversion, "Body" and "Pocket") on model tree.Two geometries have to be created. The shape will be visible by changing the property of the shape (ex. Please note that the shape may be set to invisible in the file "TestShape-changed.FCStd" after editing.

When the script is run, edited shape will be saved in file "C:\Test\TestShape-changed.FCStd". C:\Test>"C:\Program Files\FreeCAD 0.19\bin\FreeCADCmd.exe" Automation.py For example, on Windows, if FreeCAD was installed at default path, we can run the script "Automation.py" on "C:\Test" with following command on command prompt. To run the Python script, we use command line version FreeCAD that is named "FreeCADCmd". Performs shape editing with command line version FreeCAD So this is the Python script to be performed. Please select "UTF-8" as character code on saving. We save them in a file named "Automation.py". So, after closing the document on FreeCAD, we type the each line of abobe code into Python console and check which code is needed.Īfter removing unnecessary one, remained code will be as following. The displayed source code includes so many unnecessary code such as GUI display updating. Tv.show( for ref in ActiveSketch.ExternalGeometry]) Tv.show( for ref in ActiveSketch.Support if not ref.isDerivedFrom("PartDesign::Plane")]) Tv.hide(tv.get_all_dependent(App.getDocument('TestShape').getObject('Body'), 'Pocket.Sketch001.')) Tv = Show.TempoVis(App.ActiveDocument, tag= ) # ('TestShape','Body','Pocket.Sketch001.')ĪctiveSketch = App.getDocument('TestShape').getObject('Sketch001') Gui.activateWorkbench("PartDesignWorkbench") # Changes the radius of the hole at center # Gui.ActiveDocument=Gui.getDocument("TestShape") # App.ActiveDocument=App.getDocument("TestShape") Shape that will be changedĪbobe operations generate following source code on Python console (Some comments were added for easy reading). Then we save it as "TestShape-changed.FCStd" on same folder. Here we read a FreeCAD file (TestShape.FCStd on "C:\Test" folder) and change the radius of the hole at center (that is defined on Sketch001) from 15 mm to 10 mm. Performs shape editing with GUI as normally ( Sample FreeCAD file). ![]() Right-click the Python console and select "Clear console" to clear all displayed source code onece. At first we check the source code to see what kind of source code are generared from the operation that we want to perform. On FreeCAD, GUI operations will be converted to source code and they will be execute to on FreeCAD core components. In this page, we record operations on FreeCAD as a Python script and execute it with command line version FreeCAD "FreeCADCmd".
