stl-thumbnailer (Fedora 34)

• Unterstützt *.scad und *.stl
• funktioniert für *.stl aber nicht für uppercase *.STL. Man muss dies per Hand unbenennen
• funktioniert nur für binary STLs. Selbst wenn stl-thumbnailer für STL-Dateien statt OpensCAD die Software stl-thumb verwendet, wird nur binary untestützt, obwohl stl-thumb an sich ASCII unterstützt.  Hier kann "/usr/share/thumbnailers/stl.thumbnailer" editiert werden

vim /usr/share/thumbnailers/stl.thumbnailer

Exec=/bin/stl-thumb %i %o --size %s

F3D

https://f3d.app

works for a lot of formats, like DXF, STEP, STL, ...

.dxf thumbnail is not shown correctly for 2D DXF

Make it compatible to Fedora:

sudo dnf install alien
sudo alien --to-rpm -vv f3d-1.3.1-Linux.deb
sudo rpm -ivh f3d-1.3.1-2.x86_64.rpm --nodeps --force
 
#th thumbnailer gets installed to /usr/share/thumbnailers/

Fix to rotate dxf 90° by adding --up parameter:

cat /usr/share/thumbnailers/f3d.thumbnailer
