It's basically a port of #10951 to the new start page implementation. Note: Icon files are not removed but re-used instead. The commit adds some new functions: * getThumbnailsImage() Returns the name of the PNG inside a project file * getThumbnailsName() Returns the directory name containing the image files * getThumnailsParentDir() Returns the parent directory of the directory containing the image files * getThumbnailsDir() Returns the path to the thumbnail directory. There is no need to always create a unique directory after each restart because it doesn't harm if the thumbnail directoy contains deprecated files. * createThumbnailsDir() Creates the thumbnail directoy if it doesn't exist yet. * getSha1Hash Helper function to compute a SHA-1 hash of a given path. If the same path is passed then the hash value will be the same. This way it can be avoided to create a different image file from a project file after each restart. * getUniquePNG Computes the path of a PNG image file for a given project file. It's also possible to pass an arbitrary string as argument. * useCachedPNG If the PNG image exists and if it's newer than the project file True is returned and False otherwise. For a given project file it is checked if the thumbnail directory already contains a cached image. If it's newer than the project file it will used, otherwise it will be re-created. Fix freecadCanOpen() abd DisplayedFilesModel::addFile() to also check for lower-case file extensions.

Overview
-
Freedom to build what you want FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history to change its parameters.
-
Create 3D from 2D and back FreeCAD lets you to sketch geometry constrained 2D shapes and use them as a base to build other objects. It contains many components to adjust dimensions or extract design details from 3D models to create high quality production-ready drawings.
-
Designed for your needs FreeCAD is designed to fit a wide range of uses including product design, mechanical engineering and architecture, whether you are a hobbyist, programmer, experienced CAD user, student or teacher.
-
Cross platform FreeCAD runs on Windows, macOS and Linux operating systems.
-
Underlying technology
- OpenCASCADE A powerful geometry kernel, the most important component of FreeCAD
- Coin3D library Open Inventor-compliant 3D scene representation model
- Python FreeCAD offers a broad Python API
- Qt Graphical user interface built with Qt
Installing
Precompiled packages for stable releases are available for Windows, macOS and Linux on the Releases page.
On most Linux distributions, FreeCAD is also directly installable from the software center application.
For development releases visit the weekly-builds page.
Other options are described on the wiki Download page.
Compiling
FreeCAD requires several dependencies to correctly compile for development and production builds. The following pages contain updated build instructions for their respective platforms:
Reporting Issues
To report an issue please:
- Consider posting to the Forum, Discord channel, or Reddit to verify the issue;
- Search the existing issues for potential duplicates;
- Use the most updated stable or development versions of FreeCAD;
- Post version info from
Help > About FreeCAD > Copy to clipboard; - Restart FreeCAD in safe mode
Help > Restart in safe modeand try to reproduce the issue again. If the issue is resolved it can be fixed by deleting the FreeCAD config files. - Start recording a macro
