| Der Navigationswürfel wurde überarbeitet, um diese neuen Funktionen zu ermöglichen:
| Der Navigationswürfel wurde überarbeitet:
* Es gibt jetzt Kantenflächen, um die Szene in Winkeln von 45° zu betrachten.
* Es gibt jetzt Kantenflächen, um die 3D-Ansicht um 45° zu Drehen.
* Die neue Voreinstellungsoption [[Preferences_Editor/de#Navigation|Nächste Drehung]] erlaubt es, die Szene in der nächstgelegenen sinnvollen Position zu betrachten. Wenn sie ausgeschaltet ist, wird das Anklicken einer Würfelfläche immer an der gleichen Position angezeigt, unabhängig davon, in welchem Würfelzustand du dich befandest, als du die Fläche angeklickt hast. Klicke auf das Bild auf der linken Seite, um zu sehen, was das bedeutet. Versuche die gleiche Klicksequenz wie im Bild ohne die Option ''Drehen zum nächstgelegenen'', um den Unterschied zu erleben.
* Eine neue Einstellung [[Preferences_Editor/de#Navigation|Drehen zum nächstgelegenen]]
* Wenn du auf den Punkt oben rechts im Würfel klickst, kannst du schnell die Rückansicht der aktuellen Szene sehen.
wurde eingeführt. Wenn aktiviert, wird die 3D-Ansicht zur nächstgelegenen logischen Position, basierend auf der aktuellen Ausrichtung des Würfels, gedreht, wenn eine Würfelfläche angeklickt wird. Andernfalls ergibt das Anklicken einer Fläche immer dieselbe Ausrichtung. Um den Unterschied zu verstehen, kann man die gleiche Klicksequenz ausprobieren, die in der Animation gezeigt wird, mit "Drehen zum nächstgelegenen" einmal aktiviert und einmal deaktiviert.
* Die Größe des Würfels kann über die Einstellungsoption [[Preferences_Editor/de#Navigation|Würfelgröße]] angepasst werden.
* Wird auf die neue runde Schaltfläche in der rechten oberen Ecke des Würfel geklickt, kann schnell auf die Rückansicht der aktuellen Szene gewechselt werden.

| When using {{MenuCommand|Edit → Copy}} or {{MenuCommand|Edit → Duplicate selection}} for an object with dependencies there is a new {{Button|Use Original Selections}} button in the object selection dialog. Click this button to copy/duplicate only the objects you originally selected prior to opening the dialog, ignoring dependencies and ignoring any actions you might have taken while the dialog was open, such as checking or unchecking some of the checkboxes. The effect is the same as if you had unchecked all the checkboxes next to the objects you did not originally select and pressed OK. Note: special care should be taken when copying/duplicating TechDraw Pages. It is recommended to also copy/duplicate all of the children of the Page (Templates, Views, Dimensions, etc.). Otherwise changes to one of the Pages will also impact the other page, for example, deleting one of the Views in one Page also removes it from the other Page. Deleting one of the pages will also remove all the content from the other Page if copies of the content are not also made.

| [[File:PrefPacks_relnotes_0.20.png|384px]]
| A new type of add-on called a [[Preference_Packs|Preference Pack]] was added, allowing a subset of a user preferences file (user.cfg) 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]

On Linux, the default location of FreeCAD's configuration, data and cache files was changed to follow the [https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html XDG Base Directory Specification]. [https://forum.freecadweb.org/viewtopic.php?f=9&t=63648 Forum discussion]. Here is a comparison of the old and new locations:

| The [[Std_AddonMgr|Addon Manager]] was modified to support the distribution of Preference Packs, and to display information found in an addon's metadata. The Addon Manager also includes improved support for Addons whose source code is located at several different git hosting locations. Networking support was improved to provide more robust handling of SSL connections and support for proxies requiring authentication. Support was added for automatically adding macro buttons to the toolbar after installing, for disabling Addons without removing them, and for switching which git branch of an Addon is checked out. Finally, the user interface was modified to improve searching and display of different list filters.

| '''New properties for Arch Structure objects''':

* '''BasePerpendicularToTool''': it creates a copy of the Base (extrusion profile) at the beginning of the Tool (extrusion path) and places it perpendicular to the first edge of the tool. It is the same as attaching the Base with MapMode=NormalToEdge, but it is automatic and allows to reuse the same Base object for multiple Structures. When BasePerpendicularToTool = True, more properties control the placement of the Base relative to the Tool axis. They are shown in the attached image.

* '''ToolOffsetFirst''' and '''ToolOffsetLast''': extend/trim the Structure at the start and end respectively (the real length of the Structure is available in the ComputedLength read-only property).

* '''BaseRotation''': rotate the Base (the rotation is around the Base's "(0,0)" point which is the center for [[Arch_Profile|Arch Profiles]], the origin for Sketches and usually the first point for [[Draft_Wire|Draft Wires]]).

* '''BaseOffsetX''' and '''BaseOffsetY''': move the Base (extrusion profile).

* '''BaseMirror''': mirror the Base (extrusion profile).

A new command '''Create multiple Arch Structure''' was also added. It uses the first selected object as a Base, and creates Arch Structures objects for every Edge of the other selected objects. Then, the properties of individual Structure objects can be adjusted in the Property editor. This command was added for workflow with a master Sketch (there is risk of topological naming problem unless you create non-parametric copy of the master Sketch or use Realthunder's version).

Support for '''2D data''' such as linework, hatches, texts and dimensions is now enabled in IFC import and export, which contributes to making the IFC format more and more suitable for traditional 2D CAD work. A similar effort is being made in [https://blenderbim.org BlenderBIM]. More 2D workflow improvements are documented [https://forum.freecadweb.org/viewtopic.php?p=563067#p563067 in this forum thread].

* '''Important:''' Starting from this release, FreeCAD will use [https://en.wikipedia.org/wiki/International_System_of_Units SI units] (m, kg, s, K, A, mol, cd) to write the [[FEM_SolverElmer|Elmer solver]] input files (''case.sif'' and ''mesh.nodes'').

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.

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.

Revision as of 14:06, 16 November 2023

FreeCAD 0.20 wurde am 14 Juni 2022 veröffentlicht, es kann von der Download-Seite heruntergeladen werden. Diese Seite listet alle Neuerungen und Änderungen auf.

Ältere FreeCAD-Versionshinweise findet man in der Funktionsliste.

Modell eines 775 Gleichspannungsmotors von Benutzer "jimmihenry", siehe Users Showcase.
Das Modell wurde komplett mit den wöchentlichen development snapshots von FreeCAD 0.20 erstellt. Die Bilder für die animierte Grafik wurden mit dem FreeCAD-Makro Bildschirm Wiki erstellt. Die animierte GIF-Grafik selbst wurde unter Verwendung von GIMP erstellt. Für diese Versionshinweise wurde es mit ezgif zugeschnitten und in seiner Größe angepasst.

Allgemeines

freecad.org

Wir freuen uns darüber, dass das KiCAD-Projekt durch die KiCAD services corp. unsere Domain freecad.org sponsert. Jetzt sind alle FreeCAD-Webseiten unter freecadweb.org und freecad.org zu finden.

Bug/Issue tracker

Die FreeCAD-Fehlerverfolgung ist nach GitHub umgezogen: https://github.com/FreeCAD/FreeCAD/issues

Hinweis: Nur Fehlermeldungen, die zuvor im Forum diskutiert wurden, werden berücksichtigt. Fehlermeldungen ohne Diskussion werden geschlossen.

Ein neues Hilfesystem

The help system was rewritten and upgraded to display information directly from our Wiki. The system now relies on the Help Addon. When you first use the Help tool or the What's this? tool you will be asked to install it.

Benutzeroberfläche

Der Navigationswürfel wurde überarbeitet:

wurde eingeführt. Wenn aktiviert, wird die 3D-Ansicht zur nächstgelegenen logischen Position, basierend auf der aktuellen Ausrichtung des Würfels, gedreht, wenn eine Würfelfläche angeklickt wird. Andernfalls ergibt das Anklicken einer Fläche immer dieselbe Ausrichtung. Um den Unterschied zu verstehen, kann man die gleiche Klicksequenz ausprobieren, die in der Animation gezeigt wird, mit "Drehen zum nächstgelegenen" einmal aktiviert und einmal deaktiviert.

  • Wird auf die neue runde Schaltfläche in der rechten oberen Ecke des Würfel geklickt, kann schnell auf die Rückansicht der aktuellen Szene gewechselt werden.
  • Die Größe des Würfels kann jetzt mit der Einstellung Würfelgröße angepasst werden.

Forumsdiskussion, Pull request #4502 .

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. Click the image on the left so see an animation of the selection. If a selected edit mode is not applicable, the object's default edit mode is used instead. Pull request #5110.
The Tree view context menu has the new entry Add dependent objects to selection.
Forum discussion, Pull request #4133.

In the image the Hole001 object was selected and then its
dependencies were added to the selection via the context menu.

The new tool Section Cut allows to get non-hollow and also persistent cuts of parts and assemblies.
Forum discussion, Pull request #4118.

Core

When using Edit → Copy or Edit → Duplicate selection for an object with dependencies there is a new Use Original Selections button in the object selection dialog. Click this button to copy/duplicate only the objects you originally selected prior to opening the dialog, ignoring dependencies and ignoring any actions you might have taken while the dialog was open, such as checking or unchecking some of the checkboxes. The effect is the same as if you had unchecked all the checkboxes next to the objects you did not originally select and pressed OK. Note: special care should be taken when copying/duplicating TechDraw Pages. It is recommended to also copy/duplicate all children of the Page (Templates, Views, Dimensions, etc.). Otherwise changes to one Page will also impact the other page. For example, deleting a View on one Page also removes it from the other Page, or deleting a page will also remove all its content from the other Page.
A new type of add-on called a Preference Pack was added, allowing a subset of a user preferences file (user.cfg) 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. Forum discussion
The "Workbenches" preference panel was modified to support the ability to "autoload" workbenches on FreeCAD startup.

On Linux, the default location of FreeCAD's configuration, data and cache files was changed to follow the XDG Base Directory Specification. Forum discussion. Here is a comparison of the old and new locations:

Description Old location New location Defaults to
Configuration files $HOME/.FreeCAD $XDG_CONFIG_HOME/FreeCAD $HOME/.config/FreeCAD
Data files $HOME/.FreeCAD $XDG_DATA_HOME/FreeCAD $HOME/.local/share/FreeCAD
Cache files /tmp $XDG_CACHE_HOME/FreeCAD $HOME/.cache/FreeCAD

If you wish to keep using the old locations you may start FreeCAD with the --keep-deprecated-paths option.

Erweiterungsverwalter

The Addon Manager was modified to support the distribution of Preference Packs, and to display information found in an addon's metadata. The Addon Manager also includes improved support for Addons whose source code is located at several different git hosting locations. Networking support was improved to provide more robust handling of SSL connections and support for proxies requiring authentication. Support was added for automatically adding macro buttons to the toolbar after installing, for disabling Addons without removing them, and for switching which git branch of an Addon is checked out. Finally, the user interface was modified to improve searching and display of different list filters.

Arbeitsbereich Architektur

SketchArch workbench

With the Attach Feature it is now possible to place Windows and Equipment parametrically and intuitively in relation to Walls. To use this feature the experimental external SketchArch Workbench must be installed. Add-on and ReadMe on Github (Not yet available in the Add-on Manager).

Forum discussion

New properties for Arch Structure objects:
  • BasePerpendicularToTool: it creates a copy of the Base (extrusion profile) at the beginning of the Tool (extrusion path) and places it perpendicular to the first edge of the tool. It is the same as attaching the Base with MapMode=NormalToEdge, but it is automatic and allows to reuse the same Base object for multiple Structures. When BasePerpendicularToTool = True, more properties control the placement of the Base relative to the Tool axis. They are shown in the attached image.
  • ToolOffsetFirst and ToolOffsetLast: extend/trim the Structure at the start and end respectively (the real length of the Structure is available in the ComputedLength read-only property).
  • BaseRotation: rotate the Base (the rotation is around the Base's "(0,0)" point which is the center for Arch Profiles, the origin for Sketches and usually the first point for Draft Wires).
  • BaseOffsetX and BaseOffsetY: move the Base (extrusion profile).
  • BaseMirror: mirror the Base (extrusion profile).

A new command Create multiple Arch Structure was also added. It uses the first selected object as a Base, and creates Arch Structures objects for every Edge of the other selected objects. Then, the properties of individual Structure objects can be adjusted in the Property editor. This command was added for workflow with a master Sketch (there is risk of topological naming problem unless you create non-parametric copy of the master Sketch or use Realthunder's version).

Support for 2D data such as linework, hatches, texts and dimensions is now enabled in IFC import and export, which contributes to making the IFC format more and more suitable for traditional 2D CAD work. A similar effort is being made in BlenderBIM. More 2D workflow improvements are documented in this forum thread.

Forum discussion, Pull request #3229

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.
  • 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.

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.

The following options were added to the task panel of the Add OpenSCAD element feature:
Load    - load a scad file
Save    - save a scad file
Refresh - Update FreeCAD view
Clear   - Clear text input

A new text box gives feedback about OpenSCAD errors.

There is a new option to Pad along the direction of an edge in the 3D model.

Pull request #4685

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.

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.

Assembly3

The Assembly3 Workbench is available (as of March 2022) through the AddonManager. This makes for easy installation and management of the external dependencies of the workbench.

Assembly3 is used to create assemblies of different bodies contained in a single file or in multiple documents leveraging the full power of FreeCAD’s Link system. Learn more about Links in this video presentation from Realthunder.

Assembly3 Workbench uses SolveSpace as it’s solver.

Extensive documentation can be found at the main FreeCAD Assembly3 wiki page or Realthunder's GitHub Assembly3 wiki

Main features:
  • Dynamic/interactive solver: move parts with the mouse while the solver constrains the motion.
  • Links: use one single part multiple times in an assembly.
  • External links: allows usage of parts from external documents.
  • Hierarchical assemblies: permits the creation of sub assemblies.
  • Assembly freeze: assemblies that are not required to remain dynamic can be excluded from calculations and are considered fixed geometry by the asm3 solver.
  • And much more.

32-bit Windows

Since FreeCAD 0.19 we no longer officially support 32-bit 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 Edit → Preferences → Display.
