Freecad gmsh .17 how to#

There are two simple ways how to discover Python calls of FreeCAD functions. Meshing by Gmsh will be described in section :ref:`preprocessing_gmsh`. GmshĪllows to control the meshing process through a wide range of parameters. Quadrilateral meshes in 2D or tetrahedral and hexahedral meshes in 3D.

Freecad gmsh .17 generator#

It is better to use `Gmsh`_ mesh generator which can provide triangular and The meshing function of MeshPart module is limited to triangular grids so Mesh.Mesh = shFromShape(Shape=dif3.Shape, MaxLength=0.002) Mesh = doc.addObject('Mesh::Feature', 'Mesh') Part.export(, 'screwdriver_handle.step')Ī finite element mesh can be generated directly in FreeCAD using MeshPart

Ske.Placement = Base.Placement(Base.Vector(0, 0, 0),īase.Rotation(-0.707107, 0, 0, -0.707107))īase.Vector(-1.2 * radius, 0.9 * height, 0),īase.Vector(-0.8 * radius, 0.9 * height, 0))Ĭut = doc.addObject('PartDesign::Revolution', 'Revolution')Ĭreate a cylinder, make a polar array of the cylinder objects and subtract itįrom the previous result: cyl1 = doc.addObject('Part::Cylinder', 'cyl1')Ĭyl1.Placement = Base.Placement(Base.Vector(-1.1 * radius, 0, -0.2 * height),Īrr = Draft.makeArray(cyl1, Base.Vector(1, 0, 0), Base.Vector(0, 1, 0), 2, 2)ĭif2 = doc.addObject('Part::Cut', 'dif2')Ĭreate a middle hole for the screwdriver metal part: cyl2 = doc.addObject('Part::Cylinder', 'cyl2')ĭif3 = doc.addObject('Part::Cut', 'dif3')įinally, recompute the geometry, export the part to the STEP file and save theĭocument in FreeCAD format (not really needed for subsequent mesh generation,īut may be useful for visualization and geometry check): doc.recompute() Result as the cutting tool applied to uni object: ske = doc.addObject('Sketcher::SketchObject', 'Sketch') Uni = doc.addObject('Part::MultiFuse', 'uni')Ĭreate a polygon, revolve it around the z-axis to create a solid and use the Sph = doc.addObject('Part::Sphere', 'sph') Let's start by defining a sphere and a cylinder and join these objectsĬyl = doc.addObject('Part::Cylinder', 'cyl') In the following lines a geometrical model of a screwdriver handle will beĬreated. Now, a new empty FreeCAD document can be defined as: doc = newDocument()Īll new objects describing the geometry will be added to this document. Libraries and import all required modules: import sys The first step in creating a Python script is to set up a path to the FreeCAD Geometrical models in simple Python scripts. The collaboration of modeling, meshing and conversion tools and the workflow areįunctionalities of FreeCAD are accessible to Python and can be used to define

`OpenSCAD`_ with meshing functions of Gmsh.

Shows how to combine solid geometry modeling functions provided by FreeCAD or Some of the above mentioned toolsĪre handy for solid modeling, some of them are great for meshing.

Most of them are GUIīased geometrical modeling and meshing environments/tools but they also usuallyĪllow using their libraries in user scripts. Meshes like `Salome`_, `FreeCAD`_, `Gmsh`_, `Netgen`_, etc. There are several open source tools for preparing 2D and 3D finite element
