No, that's appimage.
You should chmod the file to add execution permission and run it directly. No installation necessary.
To run snap, you need to download the snap file and install it with the snap command(need to add the option --dangerous).
I need to upload the 2.2.1 snap to the official snap repository also, to ease the process.

I used the follwing version (LibreCAD-v2.2.1-x86_64.AppImage):
Version: v2.2.1
Compiler: GNU GCC 9.4.0
Erstellt am: Jan 4 2025
Qt Version: 5.15.2

I suppose this is Snap software.
