Work with several Bodies together

I often close Start Page.
But sometimes it appears again after some operations... why?

Can you upload the file?

OS: Linux Mint 18.1
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.15253 (Git) AppImage

Why are you using the AppImage on Linux Mint? Mint being based on Ubuntu, you can use the freecad-daily PPA which automatically updates. The AppImage is intended for Linux systems not based on Ubuntu.

And further, 0.18 does not see 0.17 files in Open dialog. Why?

According to your screenshots, the AppImage uses the native file dialog, which is problematic when it happens to be GTK-based. This is well-known.

The freecad-stable and freecad-daily PPAs both use the Qt file dialog which does not have this issue.

I wanted to try it at first

Oh, I did not know it

The freecad-stable and freecad-daily PPAs both use the Qt file dialog which does not have this issue.

This problem was solved with installing 0.18 from PPA.
Thanks a lot!

What is "A3 not available" message?

What is "A3 not available" message?

Have you been using the Assembly3 module? It requires a fork of FreeCAD with massive changes to its source code. It may create files that are not compatible with the original FreeCAD.

No, I have not.
It is strange...
Why does it appears?
