Otras mejoras de la interfaz de usuario

 * It is now possible to use the decimal separator belonging to the language specified for the FreeCAD interface. For example on a German Windows, when you set the interface language to English and select the new option Use selected language number format, the dot will be used as the decimal separator. See Preferences. Pull request #6364 Note: For FEM simulations using the dot as decimal separator is highly recommended to get correct results.
 * Two new mouse navigation styles have been added. One based on OpenSCAD, the other on TinkerCAD. Forum discussion OpenSCAD, Forum discussion TinkerCAD, commit 1, commit 2, commit 3.
 * It is now possible to pan the view of the dependency graph with the mouse. Forum discussion, Pull request #4638.

Ambiente de Trabajo Borrador

 * A 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.svg Draft Hatch command was introduced. It creates hatches on the faces of a selected object using patterns from AutoCAD PAT files.


 * The Draft_AddNamedGroup.svg Draft AddNamedGroup command was introduced. The Draft_AddToGroup.svg Draft AddToGroup command was extended with the same functionality.


 * Work on the Draft_SetStyle.svg Draft SetStyle command, still in progress in FreeCAD version 0.19, was completed.

 * For Draft_Dimension.svg Draft Dimensions the  for imperial architectural dimensions was introduced.


 * Draft_Shape2DView.svg Draft Shape2DView objects now have an property. Setting it to  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.svg Draft Edit context menu. Forum discussion, Pull request #4811.

Otras mejoras del Borrador

 * Fixed Draft Snap Grid when the cursor is over a face. Forum discussion. 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.

Otras mejoras del MEF

 * Important: Starting from this release, FreeCAD will use SI units (m, kg, s, K, A, mol, cd) to write the Elmer solver input files (case.sif and mesh.nodes). This is independent of the used FreeCAD unit system.
 * Important: Starting from this release, the scale of result pipelines and their filters will use SI units (m, kg, s, K, A, mol, cd). So the displacement is given in meter, the stress in Pascal. This applies for all SI-derived FreeCAD unit systems.
 * Solving with the Calculix solver now uses all CPU cores. Pull request #6374
 * Meshing with Gmsh now uses all CPU cores. Pull request #6370
 * The element order of Gmsh meshes can be changed via the mesh dialog. Pull request #4660
 * A new constraint was added: . Pull request #4738
 * A new solver was added: . Multiple commits.
 * A new constraint was added: . Pull request #4982
 * It is now possible to have result pipelines with several filters, where some take other filters as input, some take the results directly from the pipeline. commit 708a300b
 * Material cards can now contain values for the electrical conductivity. Pull request #4647
 * Material cards added for Nitrogen and Argon. Pull request #4649
 * Support for the Gmsh mesh algorithms "HXT" (3D) and "Packing Parallelograms" (2D) added. Pull request #4654
 * Allow to set for the Gmsh property High Order Optimize a certain algorithm. Pull request #4705
 * Nonlinear solid materials with simple hardening can now have an arbitrary number of yield points. Pull request #5024
 * Allow modal adding/removal of geometric entities to constraints acting on boundaries. Pull request #5117
 * Most FEM constraint dialogs now behave uniformly and provide the same 3D object selection features. Pull request #5391

Export

 * DXF: The missing unit block was added to the header14.rub file. Pull request #5793

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.

Otras mejoras
Fixed false negatives during self-intersection tests when facets are coplanar: Pull request #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.

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.



Otras mejoras

 * 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
 * The following commands now support App::Links: Loft, Sweep, Extrude, Revolve, Reverse shapes, Mirror, Offset2D, Offset3D, Check Geometry, Ruled Surface, Cross-sections, and Thickness. Pull request #6478

Otras mejoras

 * 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
 * It is possible to offset SubShapeBinders if they are based on edges, wires or faces. Pull request #6338
 * SubShapeBinders now have the Refine property like all other PartDesign objects. Pull request #6550
 * 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
 * When a PartDesign tool is run without an active body, FreeCAD now offers to activate a body or create a new one. Pull request #4949
