Interfaz de usuario
![]() |
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 . |
![]() |
The new Std UserEditMode command allows the user to choose an edit mode that will be used when an object is double-clicked in the Tree view. If a selected edit mode is not applicable, the object's default edit mode is used instead. |
Otras mejoras de la interfaz de usuario
- 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.

- It is now possible to reverse a Draft Wire via the Draft Edit context menu. Forum discussion, pull request #4811.
- Fixed [Draft_Snap_Grid|Draft Snap Grid] when the cursor is over a face. Forum discussion. Git commit.
Ambiente de Trabajo MEF
![]() 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. |

Fixed false negatives during self-intersection tests when facets are coplanar: PR #5002.
Ambiente de Trabajo OpenSCAD
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.
Add OpenSCAD element - now has additional options
Load - load a scad file Save - save a scad file Refresh - Update FreeCAD view Clear - Clear text input
There is also a text box for feedback of OpenSCAD errors.

- 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

![]() 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. |
![]() |
When Distance and Angle is specified in the Chamfer tool and faces are selected, the distance will be applied along the selected faces. Likewise if two distances are specified then Size 1 will be applied along the selected face.
This behaviour can be swapped to the other face using the flip direction button. Forum discussion, pull request #5039 |
Otras mejoras
- 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
