Revision as of 20:49, 11 February 2022

Diese Seite verfolgt neue Funktionen, die der Entwicklungsversion von FreeCAD, die derzeit 0.20 ist, hinzugefügt werden. Wenn das Einfrieren der Funktionen von 0.20 eintritt, lösche diese Meldungen und füge keine weiteren Funktionen zu dieser Seite hinzu. FreeCAD 0.20 wird voraussichtlich im Jahr 202x veröffentlicht werden.
!!! Alle Bilder auf dieser Seite müssen den Suffix _relnotes_0.20 verwenden !!!

Fehlen Funktionen? Erwähne sie im Versionshinweise für v0.20 Forumsbeitrag.

Siehe Hilf FreeCAD für Wege, zu FreeCAD beizutragen.


'FreeCAD 0.19 wurde veröffentlicht auf DD Month 202x, hole es von der Herunterladen Seite. Dies ist eine Zusammenfassung der interessantesten Änderungen. Die vollständige Liste der Änderungen kann im MantisBT bugtracker FC 0.20 Änderungsprotokoll eingesehen werden.

Ältere FreeCAD Versionshinweise findest du unter Funktionsübersicht.

Höhepunkte

Entwicklung

Since this release FreeCAD can only be compiled using Qt 5 and Python 3.

Um FreeCAD unter Windows kompilieren, gibt es verschiedene Libpacks (vorgepackte Bibliotheken):

  • Libpack für Windows mit Qt xx, OCC yy, und Python zz

Lowest supported Python version is 3.6.9 according to this FC forum thread.

Supported operating systems:

  • Linux Ubuntu Bionic Beaver (18.04) and Focal Fossa (20.04)
  • MacOS minimum version 10.12 Sierra

Dokumentation

Bekannte Begrenzungen

Benutzeroberfläche

Der Navigationswürfel wurde überarbeitet, um diese neuen Funktionen zu ermöglichen:
  • Es gibt jetzt Kantenflächen, um die Szene in Winkeln von 45° zu betrachten.
  • Die neue Voreinstellungsoption 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.
  • Wenn du auf den Punkt oben rechts im Würfel klickst, kannst du schnell die Rückansicht der aktuellen Szene sehen.
  • Die Größe des Würfels kann über die Einstellungsoption Würfelgröße angepasst werden.

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 at 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 by the user and then
its dependencies were added to the selection via the context menu.

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 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.

  • 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.

Wirkung von Netzweite von Krümmung; links: auf 12 gesetzt, rechts: deaktiviert

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.

Improved support for NASTRAN GRID elements

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.

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.

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

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.
