Revision as of 08:02, 30 August 2021
Are features missing? Mention them in the Release notes for v0.20 forum thread.
See Help FreeCAD for ways to contribute to FreeCAD.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.
Highlights
General
Python 3 and Qt5
Some issues
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:
Documentation
Known Limitations
User interface
The navigation cube was reworked to enable these new features:
|
Tooltips now display the command name in the title, making it easier for new users to look for help. At the end of the tooltip the "internal" command name is added in parentheses: (Std_WhatsThis). This is also the name of the page that documents the command in the Wiki. Forum discussion, pull request #4978 . |
Further User Interface Improvements
- It is now possible to pan the view of the dependency graph with the mouse. Forum discussion, pull request #4638.
- Fixed an issue where using a tablet pen devices (e.g. Wacom tablet) was slow to the point of being completely unusable. Forum Discussion, pull request #4687.
App::Link and assembly
Core system, App, Base, and Gui namespaces
Addon Manager
Arch Workbench
Draft Workbench
Further Draft Improvements
- It is now possible to reverse a Draft Wire via the Draft Edit context menu. Forum discussion, pull request #4811.
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 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 FEM MeshGmshFromShape. |
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
Import
Material handling
Mesh
Further improvements
OpenSCAD Workbench
Interoperability with OpenSCAD has been improved, adding support for several operations missing from earlier versions (linear extrude with rotations, rotational extrusions). Several operations are modified to provide improved FreeCAD object equivalents, particularly for twisted extrusions. Surface generation from discrete data was modified to give more OpenSCAD-like results, rather than splined surfaces.
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. |
Further improvements
- The Helix feature has the new mode Height-Turns-Growth to create flat spirals. Forum thread PR #4590
- The Sprocket feature can now create also ISO-normed sprockets. Forum thread PR #4478
Path Workbench
Render Workbench
Sketcher Workbench
New Split function to split existing lines or arcs. | |
New Rounded rectangle tool to create rectangles with rounded corners. | |
New Centered rectangle tool to define rectangles via a center point. | |
New Radiam function to automatically assign weight on B-spline pole, diameter on complete circle, or radius on arc. Support multi-selection as diameter/radius tools. | |
New Remove Axes Alignment constraint tool to remove axes alignment while trying to preserve the constraint relationship of the selection. |
Further improvements
- Refactored Trim support. Pull Request Forum discussion <-- Needs screencasts
- The behavior of the Slot tool has changed. Slots can now be created by defining the center of both semicircles. Pull request Forum discussion
- Visibility automation allows to open Sketcher in Section mode when entering edit mode. Pull request Forum discussion
- Visibility automation allows to force camera in Orthographic mode when entering edit mode. Pull request Forum discussion
Bug fixes
- Fix 'Reference' option not working for radius/diameter at creation time PR for radius PR for diameter Forum discussion
Spreadsheet 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.
