| A new type of add-on called a [[Preference_Packs|Preference Pack]] was added, allowing a subset of a user preferences (user.cfg) file to be saved, distributed, and easily applied by other users. Preference Packs can be use to distribute "Themes," for example, by allowing a developer to include both a Qt stylesheet for widgets as well as a set of other colors and styles for items in the user interface that cannot be set using a stylesheet (e.g. text colors in the Python editor or report view, etc.). Anything that can be configured via a user.cfg file can be set using a Preference Pack. [https://forum.freecadweb.org/viewtopic.php?f=17&t=62477 Forum discussion] |

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. |

||
New options were added to support running either FreeCAD, OpenSCAD, or both, in sandboxed environments such as AppImages and Snap packages: data can now be transferred to and from OpenSCAD via the standard temporary directory mechanism, via a user-specified temp directory that both executables have access to, or new to OpenSCAD 2021.1, via a "stdout pipe" mechanism, bypassing temporary files entirely. |

A new type of add-on called a Preference Pack was added, allowing a subset of a user preferences (user.cfg) file to be saved, distributed, and easily applied by other users. Preference Packs can be use to distribute "Themes," for example, by allowing a developer to include both a Qt stylesheet for widgets as well as a set of other colors and styles for items in the user interface that cannot be set using a stylesheet (e.g. text colors in the Python editor or report view, etc.).

Arbeitsbereich Entwurf
- A Global checkbox was added to the task panel of many drafting commands. Checking it allows input of coordinates in the global coordinate system even if the working plane is not aligned with the global XY plane.
- The Draft Hatch command was introduced. It creates hatches on the faces of a selected object using patterns from AutoCAD PAT files.
- The Draft AddNamedGroup command was introduced. The Draft AddToGroup command was extended with the same functionality.
- Work on the Draft SetStyle command, still in progress in FreeCAD version 0.19, was completed.
- A double-click edit option was added for Draft Texts. It opens the same edit task panel used when creating a text.
- For Draft Dimensions the
arch
AnsichtUnit Override for imperial architectural dimensions was introduced.
- Draft Shape2DView objects now have an DatenAuto Update property. Setting it to
false
can be useful if there are many Draft Shape2DViews in a document or if they are complex.
- It is now possible to reverse a Draft Wire via the Draft Edit context menu. Forum discussion, Pull request #4811.
Weitere Entwurf Verbesserungen
- Behoben Entwurf Fang Gitter, wenn sich der Mauszeiger über einer Fläche befindet. Forumsdiskussion. Git commit.
- New Draft Texts are now aligned with the working plane, Pull request #5092.
- Support for two DWG converters was added: LibreDWG and QCAD pro. See Import Export Preferences and FreeCAD and DWG Import for more information.
Arbeitsbereich FEM
|
Es gibt eine neue Eigenschaft für den Gmsh Vernetzer. Die Anzahl der Netzelemente pro mal dem Radius der Krümmung kann angegeben werden. Der Standardwert ist 12. Um ein feineres Netz an kleinen Ecken oder Löchern zu erhalten, kann dieser Wert erhöht werden, um bessere Ergebnisse zu erzielen. Diese Funktion erfordert Gmsh 4.8 oder eine neuere Version. |
|
FreeCAD erlaubt nun die Auswahl eines Algorithmus sowie die 3D Netzrekombination für den Gmsh Vernetzers. Für weitere Details über die Rekombination von Netzelementen siehe FEM NetzGmshAusForm. |
Weitere FEM Verbesserungen

Improved support for NASTRAN GRID elements
The Mesh import tool now supports the high-precision "GRID*" element. The standard-precision "GRID" element was also improved, now supporting both space-delimited numeric input as well as fixed-field-width input, per the NASTRAN95 format documentation.
Weitere Polygonnetz Verbesserungen
Fixed false negatives during self-intersection tests when facets are coplanar: Pull request #5002.
OpenSCAD Arbeitsbereich
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.
New options were added to support running either FreeCAD, OpenSCAD, or both, in sandboxed environments such as AppImages and Snap packages: data can now be transferred to and from OpenSCAD via the standard temporary directory mechanism, via a user-specified temp directory that both executables have access to, or new to OpenSCAD 2021.1, via a "stdout pipe" mechanism, bypassing temporary files entirely.
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.
Arbeitsbereich Formteil
Tapered extrusion of a sketch with an inner structure. |
A tapered extrusion of inner structures now creates usable results. Previously, inner structures were extruded as if they were stand-alone and not part of a structure. |
Weitere Formteil Verbesserungen
- The dialog to edit Cylinders now allows to specify an angle relative to the normal of the chosen attachment plane. This way one can create skew cylinders. Pull request #4708

Padding along an edge from the model. Click on the image to show the animation. |
There is a new option to pad along the direction of an edge in the 3D model. |
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 | |
A loft with multiple sections, the final one is a vertex. |
It is now possible to create an Additive or Subtractive Loft, or an Additive or Subtractive Pipe towards, or from, a Vertex of either a sketch or a body. This allows to create pyramids for example. Note: Vertices in sketches are created as construction geometry. To use them as endpoints of lofts, you must first change them to normal geometry. Pull request #5170 (for lofts), Pull request #5193 (for pipes) |
A tapered pocket within a non-tapered pad. |
The dialog for Pad and Pocket offers to set a taper angle for the extrusion. |
Pocketing along different directions. Click on the image to show the animation. |
It is now possible to specify the direction for the pocket extrusion. |
* The dialog to edit Cylinders (additive and subtractive) now allows to specify an angle relative to the normal of the chosen attachment plane. This way one can create skew cylinders. Pull request #4708 | |
The Helix feature has the new mode Height-Turns-Growth to create flat spirals. | |
A single Pad and a single Revolution with nested profiles. The base block is only there to ensure that the part is a single solid. |
All PartDesign features that can extrude sketches can now handle sketches with nested profiles that form islands. For example it is possible to revolve a sketch consisting of 3 nested circles with the same center point. Note: Extruding nested profiles only works if the result is still a single body. |
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. |

- In the Helix feature one can now also use the sketch normal as axis. Pull request #5199
- The Sprocket feature can now also create ISO-normed sprockets. Forum thread Pull request #4478
- The Loft and Pipe features now allow using the body's faces for sections. Pull request #5155
- It is now possible to select several faces before calling the Pad or Pocket dialog. In this case the first selected face will be used to determine the default padding/pocketing direction. commit d34a5616
- In the Chamfer and Fillet dialogs all edges of a body can be selected via the context menu while in Add mode. Pull request #5269
When you selected a 3D object before clicking the icon to create a fillet or chamfer, all object edges will automatically be selected. Pull request #5328 - Chamfer and Fillet dialogs now each have a new Use all edges checkbox, which is connected to the Use All Edges property for these objects. When the box is checked the property is set to True, when unchecked the property is set to False. When Use All Edges is True there is protection against the topological naming problem because then all of the edges of the base object are used regardless of how many edges there are. Pull request #5340
- Plane selection when adding a new sketch can now be achieved with a single-click in the 3D View. Pull request Forum discussion
