[Solved] Get extension from an unsaved document

[Christopher]

Hello,

does someone know a way, to get the extension (.top .dft. wod. cam) of the active document, when this has not been saved yet?

Should be easy, but i dont find the good command.

i solved this with reading the window-title from TopSolid.
It contains the informatin "Design, 2D Draft...".
Not perfect, but OK.
