Прочие улучшения верстака Assembly
- An Exploded View was added. Pull request #12419
- Assembly icons were updated and the experimental features exposed. Pull request #13866
- Angle, Perpendicular and Parallel joints were added. Pull request #14008
- A Bill of Materials feature was added. Pull request #14198

- Coming from the BIM workbench, some "all-in-one" Arch tools have been split into different use cases: The Arch BuildingPart tool has been split into the BIM Building and BIM Level tools, the Arch Structure tool has been split into BIM Column, BIM Beam and BIM Slab, and the Arch Window tool has been split into BIM Window and BIM Door. Internally, those tools still produce the same object, only with different IFC types and presets applied. Pull request #13783
- NativeIFC has also been merged into the new BIM workbench. With NativeIFC, you can now work on IFC files in FreeCAD natively, with no more translation to and from the FreeCAD file format. Read more on the NativeIFC page. Pull request #13783
- The Arch CutPlane command has been improved. It is now nesting and link aware and the selection is more flexible. Edges can also be selected making the Arch CutLine command obsolete. Pull request #11254 and Pull request #11792
- The BIM preferences have been checked and improved. The pages in the Preferences Editor have a new layout. Pull request #11940 and Pull request #12038
- An Opening only preset has been added to the Arch Window command. Pull request #12209
- The Arch Roof object now has a Subvolume property. This allows to use a custom solid object as the subtraction volume for a roof. Pull request #12346
- Furthermore for an Arch Roof object that uses a solid object as its Base an appropriate subtraction volume is now automatically generated. Just as a wire-based roof, such a roof can be subtracted from the walls of a building with Arch Remove. Pull request #13221
- The Arch Reference tool has been upgraded: reference objects can now use whole file contents instead of having to choose a part, support for DXF and IFC files has been added. Pull request #13287
- FreeCAD now has a new BIM example file. Pull request #14937
- The new BIM workbench also offers a series of new management tools, to help you set up your project, or bulk manage IFC properties of your objects. Read more on the BIM Workbench page.
- IfcOpenShell, another piece of open-source software needed to work with IFC files in FreeCAD, is now bundled in all official installer packages offered by the FreeCAD team. If you get FreeCAD from a third-party provider, such as your Linux distribution, where IfcOpenShell has not made it yet as an official package, the BIM workbench offers a utility tool to download and install IfcOpenShell. And if you have no use for IFC, the BIM workbench still works 100% without IfcOpenShell.
- The toolbars and menus of the BIM Workbench were reworked. Pull request #14087
Верстак CAM
Прочие улучшения верстака CAM
- Rest machining was reimplemented to take input from the G-code of earlier operations (instead of using the internals of Area operations). This enables support for rest machining in Area operations after non-Area ones (most notably Adaptive). Pull request #11939
- G43 tool height compensation was added to the centroid CAM post-processor. Pull request #12652
- A Feed retract option was added to drilling operation settings for reaming and boring. Pull request #13254
- A new CAM simulator based on low-level OpenGL functions (faster and more precise) was added. Pull request #13884 and Pull request #15597
- The Vcarve operation was reworked to include features commonly available in other CAM software (Step down, Finishing pass, Head movement optimization and debugVoronoi method) making it possible to drastically improve the carved surface quality while increasing the carving speed up to 50%. Pull request #14093
- Machinability material models were added along with several materials. Pull request #14460, Pull request #15910 and Pull request #16021
Верстак Draft
- A justification option and several related properties have been added to Draft ShapeStrings. Pull request #10233
- Radial dimensions now only show a single arrow. Pull request #10655
- An Oblique Angle property has been added to Draft ShapeStrings. Pull request #10783

- The history feature and the alignment options of the Draft SelectPlane command have been improved. Pull request #11062
- The behavior of the grid has been improved. Its visibility is now stored per 3D view. When switching to a different workbench all grids are hidden (a fine-tuning parameter is available to disable this). Pull request #11336
- The Draft preferences have been checked and improved. Some preferences have been added, obsolete preferences have been removed. The pages in the Preferences Editor have a new layout and show units where applicable. Restarting FreeCAD after changing a Draft preference is no longer required. Pull request #11379, Pull request #11503, Pull request #11512, Pull request #11550, Pull request #11579, Pull request #11585, Pull request #11677, Pull request #11694 and Pull request #16603
- A new Mouse delay setting has been added to the General Draft preferences. If it's non-zero (default is 1 s), after entering a number in one of the task panel input fields, mouse movement will be disabled, and thus won't change the value in the input field, for a given time in seconds. Setting a very large value practically disables mouse movement until the command is finished. Pull request #12624
- A button to quickly change the color of the grid has been added to the task panel of the Draft SelectPlane command. Pull request #13051
- A Fuse property has been added to Draft PointArrays, Draft PathArrays and Draft PathTwistedArrays. Pull request #13172 and Pull request #13191

- The Model → Constraints without solver menu was removed from the GUI. The listed constraints could not be used. Pull request #10457 and Pull request #10459
- The word "constraint" was removed from the names and descriptions of most features in the FEM workbench to ensure the correct nomenclature. The names were changed in such a way to fit the standards in the FEA industry and to make them intuitive for new users. Pull request #10519 and Pull request #10799
- New icons were added for Solver CalculiX Standard, Solver job control and Run solver calculations for greater intuitiveness. Pull request #10885
- Solver CalculiX (new framework) was removed from the GUI since it's unfinished and unnecessary at the moment. Its examples were also removed. Pull request #10823 and Pull request #12876
- The layout of some postprocessing tool task panels was improved to reduce the size of the horizontal space occupied by them. Pull request #11066
- The FEM ConstraintTemperature task panel was reworked to fix issues when editing this feature. Pull request #11126
- An old issue with the FEM PostFilterDataAlongLine being able to plot only magnitude, not vector components of a selected output variable was finally fixed. Pull request #10992
- The FEM ConstraintForce and FEM ConstraintPressure were overhauled to make them work better on the source code side. Pull request #10935 and Pull request #10923
- The FEM PostFilterDataAtPoint now has a PointSize property to set the size of the point symbol for more visibility. Pull request #11054
- For clarity, the FEM mesh region command was relabeled to FEM mesh refinement in the GUI (the command name remains unchanged). Pull request #11489
- The magnitude of gravity acceleration can now be changed using the properties of FEM ConstraintSelfWeight. Pull request #12044
- Contact and tie constraint were significantly improved. Contact stiffness now uses the correct unit and stick slope value can be specified for friction in contact. Moreover, clearance adjustment can be specified for contact while tie constraint may have adjustment enabled or disabled. Pull request #12133
- PaStiX and Pardiso were added to supported CalculiX matrix solvers. They are the fastest ccx solvers but the possibility of using them depends on the CalculiX binary version and available additional libraries. Pull request #12478
- The Beam Reduced Integration property (set to true by default) was added to CalculiX solver settings. It enables a reduced integration scheme for beam elements, making it possible to use the pipe beam section and eliminating accuracy issues in analyses with plasticity, among others. Pull request #12513
- The unfinished Nodes set tool was removed from the GUI. It couldn't be used. Pull request #12611
- The Check Mesh CalculiX analysis procedure now generates the results mesh properly. Pull request #12612

- Now geometric nonlinearity is not automatically activated and required when a nonlinear material is used. Those are independent forms of nonlinearity. Pull request #12703
- Mixed meshes consisting of both triangular and quadrilateral elements are now displayed properly in the results pipeline. Pull request #12740
- The Output Frequency property was added to CalculiX solver settings. It defines the frequency of output writing in increments. Pull request #12672
- Second-order quadrilateral elements can now be generated. Previously, the 2nd order Gmsh setting was generating 1st order quad elements because of the lack of a SecondOrderIncomplete Gmsh command which is now used internally. Those elements can also be used for 2D analyses. Pull request #12698 and Pull request #12774
- The determination of beam cross-section orientation was partially fixed. Due to a bug in the current release of CalculiX, there may still be issues with some orientations. Pull request #12833
- Cantilever FEM examples on the Start page were updated and a new one using 1D elements was added. Pull request #12871
- The format in which FreeCAD writes the force constraint is now compatible with the CalculiX format, eliminating rare issues with too long numbers. Pull request #12932
- It is now possible to export the results pipeline to the VTK format. Pull request #12987
- New incrementation control properties were added to CalculiX solver settings. Currently, in addition to the initial increment size and time period of the step, one can specify minimum and maximum increment size. Also, the Iterations Thermo Mech Maximum property was renamed to Iterations Maximum as it can now be used for static (non-thermomechanical) analyses too. Pull request #12662
- Default 2D element thickness was changed from 20 mm to 1 mm as it makes more sense in practice. Pull request #13077
- Many FEM icons were significantly improved to reduce their similarity and make it more clear what the tools do. Pull request #13130
- The Thermo Mech Type property was added to CalculiX solver settings. It makes it possible to switch a regular (coupled) thermomechanical analysis to uncoupled or a pure heat transfer one. Pull request #13296
- Min. Size property was added for Netgen mesher to prevent the generation of too small elements when meshing more complex geometries. Pull request #12794
- An old issue with a non-functioning symbol scale property for FEM constraints was finally fixed and the Scale property can now be used to adjust the size of symbols of a selected constraint. Pull request #13274
- Automatic scaling of FEM constraints was improved to better handle very small and very large objects. Pull request #13586
- Heat flux load now has a radiation heat flux mode to model surface radiation to ambient. Pull request #13466
- A few unused constraint symbol View properties were removed. Pull request #13569
- New view properties (with the main one being Color Mode) were added to FEM mesh objects so that custom color and transparency settings for meshes can be saved and restored. Pull request #13698
- Now only the last added filter under each results pipeline object is visible by default. Pull request #13820
- The task panel tips of several constraints were changed to actually reflect the rules of the geometry selection for those constraints. Pull request #13921 and Pull request #14002
- Support for heat flux results from thermomechanical analyses was added to the results pipeline. Pull request #14019
- The Section print feature was improved, adding support for heat flux and drag stress (not yet available as 3D fluid analyses with CalculiX haven't been implemented yet) results. Pull request #14046
- Body heat source can now be used with CalculiX and has two input modes - dissipation rate [W/kg] and total power [W]. Pull request #14417
- The rotation properties of the Local coordinate system were replaced with a single Rotation property for consistency. Pull request #14353
- An Erase Elements tool was added to make it possible to hide elements of a mesh selected with a polygon. Pull request #11492
- The three FEM examples on the Start page were replaced with one, containing all three variants of the cantilever beam model (1D, 2D and 3D) in Group containers. Pull request #15786
- The redundant Fix properties and checkboxes of the FEM ConstraintDisplacement were removed. Pull request #15531
- The behavior of the Cancel buttons in the task panels of the Gmsh and Netgen meshers was fixed so that they can be used to abort ongoing meshing which is particularly important when an initial guess regarding element size is too low. Moreover, the Netgen mesher was implemented, finally making it possible to use it on all systems, including Linux. Pull request #16515 and Pull request #16433
- The Quasi-structured Quad 2D algorithm missing in the Gmsh mesher was added to it along with other fixes. Pull request #15624

- The Create sketch command was added to the Part toolbar and menu since operations such as extrusion typically use sketches as input. Pull request #14318
- A new attachment mode called XY parallel to plane was added to the Engine Plane and Engine 3D. It results in an attachment similar to Object's XY but with the XY plane translated to pass through a selected vertex. In contrast to the Translate origin attachment mode, it does not move the origin in 2D/Sketcher. It can be used with origin planes, datum planes and sketches, but also with any object with a Placement property. Pull request #14372

Tool parameters were added to allow dimensioning on the go (when drawing shapes). Depending on the preference setting On-View-Parameters, they can be disabled, reduced to dimensions only (no initial coordinates) or fully enabled. Moreover, modes were added for the shape tools. They can be selected using the M key or a drop-down list in the task panel. Some tools have additional settings in the form of checkboxes in the task panel and additional keyboard shortcuts. Currently, the new features are available for points, lines, arcs, ellipses, rectangles, polygons, slots and B-splines.
