Some issues


To compile FreeCAD under Windows, there are different Libpacks (prepackaged libraries) available:

  • Libpack for Windows with Qt xx, OCC yy, and Python zz

Known Limitations

User interface

Navi Cube 0.20.gif The navigation cube was reworked to enable these new features:
  • There are now edge faces to view the scene at angles of 45°.
  • The new preferences option Rotate to nearest allows to view the scene at the nearest sensible state. When it is off, clicking to a cube face will and up always to the same position, no matter in what cube state you were when you clicked the face. Click on the image at the left side to see what this means. Try the same click sequence as in the image without the option Rotate to nearest' to experience the difference.
  • By clicking at the dot at the upper right of the cube you can quickly see the backview of the current scene.
  • The size of the cube can be adjusted by the preferences option Cube size.

FEM Gmsh-MeshSizeFromCurvature.png
Effect of Mesh Size From Curvature; left: set to 12, right: deactivated
There is a new property for the Gmsh mesher. The number of mesh elements per times the radius of the curvature can be specified. The default is 12 and to get a finer mesh at small corners or holes, this value can be increased for better results. This feature requires Gmsh 4.8 or newer.

Forum discussion, pull request #4596

FEM Gmsh-RecombinationAlgorithm.png
Effect of the rcombination algorithm; left: using Simple, right: using Simple full-quad
FreeCAD allows now to select an algorithm as well as 3D mesh recombination for the Gmsh mesher. For more details about the mesh element recombination see this Wiki page.

Pull request #4706

Further FEM Improvements

  • The element order of Gmsh meshes can be changed via the mesh dialog. PR #4660
  • Material cards can now contain values for the electrical conductivity. PR #4647
  • Material cards added for Nitrogen and Argon. PR #4649
  • Support for the Gmsh mesh algorithms "HXT" (3D) and "Packing Parallelograms" (2D) added. PR #4654
  • Allow to set for the Gmsh property High Order Optimize a certain algorithm. PR #4705

Further improvements

  • The dialog to edit Cylinders allows now to specify an angle in respect to the normal of the chosen attachment plane. This way one can create skew cylinders. Pull request #4708

PartDesign Workbench

PD Pad-Length-alog-direction.gif
Effect of the new option Length along sketch normal.
Click on the image to show the animation.
There is a new option to pad a certain length along the direction. The length is either measured along the sketch normal or along the custom direction.

Forum discussion, pull request #3893

PartDesign Cylinder direction.png The dialog to edit Cylinder (additive and subtractive) allows now to specify an angle in respect to the normal of the chosen attachment plane. This way one can create skew cylinders.
