# Release notes 0.20

This page tracks new features as they are added to the development version of FreeCAD, which is currently 0.20. When the 0.20 feature freeze happens, delete these messages, and don't add more features to this page. FreeCAD 0.20 is expected to be released in 202x.

Are features missing? Mention them in the Release notes for v0.20 forum thread.

FreeCAD 0.20 was released on DD Month 202x, get it from the Download page. This is a summary of the most interesting changes. The complete list of changes can be found in the MantisBT bugtracker FC 0.20 changelog.

Older FreeCAD release notes can be found in Feature list.

## General

### Development

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

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

Other development news:

## User interface

 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 Workbench

 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 ${\displaystyle 2\pi }$ 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. 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.

### 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

## Part Workbench

### 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

 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. 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.

## Sketcher Workbench

• It is now possible to select in the row/column context-menu at what positions new rows/columns will be inserted. Furthermore, when selecting several rows/columns, the row/column context-menu offers now to insert as many new rows/columns as selected. pull request #4704.
