General

User interface

File:Navi Cube relnotes 1.0.gif The navigation cube corner faces are now hexagonal and bigger, making them easier to click.

The font, font size and button color (the arrows around the cube) can now also be changed in the preferences.
Pull request #7876, Pull request #8266 and Pull request #8646.

File:Part SectionCut example relnotes 1.0.gif
Persistent section cut of intersecting objects.
Click on the image to see the animation.
The Section Cut tool now allows to cut intersecting objects. This is useful for assemblies where intersections of touching objects can sometimes not be avoided due to numerical issues.
Pull request #8252.
File:Measurement-Part relnotes 1.0.png The display style of measurement results created using the Part or PartDesign workbench can now be changed in the preferences.

Pull request #7148

File:WbSelector relnotes 1.0.png The workbench selector can now optionally be put in the menubar instead of the toolbar area.

Pull request #7679

FEM Workbench

File:FEM PostFilterContours relnotes 1.0.png
Iso-contours, depicting the y-component of the absolute magnetic
flux density in and around a copper wire that is flown through by
electric current at a frequency of 100 kHz.
For more info about this model, see section 14 of the Elmer Tutorials.
There is the new Contours filter filter that allows to draw iso-lines or iso-contours. Iso-contours are connected mesh nodes that have the same result field value. A typical example are electric field lines.

Pull request #8462

File:FEM Elmer-Multithread relnotes 1.0.png
Simulation result (of flowing water being heated) where 8 mesh regions
are visible (one for every CPU core used).
It is now possible to run the solver Elmer using multiple CPU cores. For more info about the caveats, see this forum post

Pull request #7159

File:FEM EquationMagnetodynamic2D relnotes 1.0.png
Simulation result of the imaginary part of the current density in
a crucible that was heated electrically by a surrounding coil.
This model is available via the FEM Examples.
For more info about this model, see section 16 of the Elmer Tutorials.
The Magnetodynamic 2D equation was added. With this it is possible to perform electromagnetic simulations in 2D.

Pull request #8355

File:FEM EquationMagnetodynamic relnotes 1.0.png
Simulation result of the imaginary part of the magnetic flux density in
and around a copper wire that is flown through by electric current at
a frequency of 100 kHz.
This model is available via the FEM Examples.
For more info about this model, see section 14 of the Elmer Tutorials.
The Magnetodynamic equation was added. With this it is possible to perform electromagnetic simulations.

Pull request #8380

File:FEM EquationDeformation relnotes 1.0.png
Simulation result of an iron U-wire that is deformed
by pressing the ends of the U together.
For more info about this model, see section 8 of the Elmer Tutorials.
The Deformation equation was added. With this it is possible to perform nonlinear elasticity analyses (deformation).

Pull request #8981

OpenSCAD Workbench

PartDesign Workbench

File:PD Counterdrill relnotes 1.0.png
A counterdrill hole.
The Hole dialog supports the screw head type Counterdrill.

Pull request #7562

Further PartDesign improvements

Path Workbench

  • Camotics integration. If camotics (version 1.2.2 or later) is installed, a new icon will be added to the Path toolbar. Select a Path Job and press the button to open the Camotics dialog. Then drag the slider to generate a simulated solid at any point in the job. You can also launch the full camotics application to run the animated simulaton. This results in a silent post-processing of the job and creation of a camotics project file. Pull request #6637
  • Additional substitution strings for automatic output naming. If output is being split into multiple files, the filenames can automatically substitute the toolcontroller label, WCS, or operation label. This is in addition to the other existing substitution strings like date, job name, etc.
  • Implemented Chipbreaking option for peck style drill cycles. Chipbreaking emits a G73 cycle which causes the control to make a very small retraction move to break the chip without fully retracting the bit from the hole. G73 is supported natively by LinuxCNC. Some other postprocessors will have to interpret the G73 and emit control appropriate codes or decompose the retraction into G1/G0 moves. Postprocessor support for G73 decomposition has been added to the "refactored" postprocessors.Pull request #7469

Plot module

Sketcher Workbench

File:Constrain B-spline knots relnotes 1.0.gif
Dragging of B-spline knots.
Click on the image to see the animation.
B-spline knots can now be dragged around and constrained like any other sketch point.

Pull request #7484

File:Sketcher-move-piece relnotes 1.0.gif
Dragging of a B-spline.
Click on the image if the animation does not start.
Dragging a B-spline now only moves the part between knots.

Pull request #7110

File:Sketcher Join Curves relnotes 1.0.gif
Click on the image to see the animation.
The Join curves tool has been added. It can combine multiple curves into a single B-spline.

Pull request #6507

File:Sketcher BackEdit relnotes 1.0.gif
Click on the image to see the animation.
Sketches can now be seamlessly edited from the front or back. When working from the back, vertices (and all geometries and constraints) are equally selectable and the section view is switched automatically.

Pull request #7417

File:Grid rework.png The Sketcher grid has been reworked. The Grid tool has been added. Automatic rescalling of grid option has been added.

Pull request #8473

File:Constraint widget.png The Sketcher Constraint widget has been reworked to simplify the UI.

Pull request #7566

File:Sketcher Element Widget relnotes 1.0.gif
Click on the image to see the animation.
The Element widget has been reworked to simplify the UI and enable simpler selection of the different parts of each geometry: Edge, start point, end point and mid point.

Pull request #7567

File:Sketcher grid relnotes 1.0.gif.gif A feature to automatically resize the grid according to the zoom level and other improvements were introduced.

Pull request #8473

File:Sketcher layers relnotes 1.0.gif Basic visual layers functionality was introduced, for now only 3 hardcoded layers are supported. Expect further improvements down the road.

This PR also removes the rendering order options (no longer needed) and the "Edit controls" widget from the task panel as all it's contents have been moved to other places or removed. Pull request #8716

Further Sketcher improvements

Spreadsheet Workbench

Further Spreadsheet improvements

TechDraw Workbench

File:TechDraw SurfaceFinishExample relnotes 1.0.png The SurfaceFinishSymbol tool was added to allow for the creation of surface finish symbols describing roughness, lay and waviness, but also denoting the type of surface treatment. It supports both ISO and ASME styles. As shown in the image, the existing LeaderLine tool can be used to properly refer oriented symbols to the edges of an object.

Pull request #7227

File:TechDraw ComplexSection relnotes 1.0.png The ComplexSection tool was added to allow for the creation of half, offset and aligned sections.

Pull request #7658

Compilation

Since this release FreeCAD can only be compiled using Qt 5.x and Python 3.x. The lowest supported Python version is 3.8 according to the FreeCAD 1.0 development goals.

To compile FreeCAD see the instructions for Windows, Linux and macOS.

The supported operating systems are:

  • Windows 7, 8, 10 and 11
  • Linux Ubuntu Focal Fossa (20.04) and newer
  • macOS: 10.12 Sierra or newer

Known Limitations

32bit Windows

Since FreeCAD 0.19 we no longer officially support 32bit Windows. FreeCAD might work on these systems, but no support is given.

Remote Desktop under Windows

Depending on the OpenGL graphics capabilities of a computer, it might be that one encounters a crash when running FreeCAD via remote desktop. To fix this upgrade your OpenGL driver. Only if this doesn't help:

  • Download this OpenGL library for 64bit Windows and extract it.
  • Rename the DLL file to opengl32sw.dll and copy it to the bin subfolder of FreeCAD's installation folder (overwrite the existing DLL there).

macOS: Start Workbench shows blank page

If the Start Workbench shows only a blank page, you must enable the option Use software OpenGL in the menu FreeCAD-1.0 → Preferences → Display.
