Dear all,

I am encountering this issue with using Flatshot and Sectionplane. I have gone through the forum along with videos, though when I try to use the commands they won't work well. The Flatshot along with the Section plane won't display all the objects that is supposed to. It only appears just 2 objects from the whole floor. The drawing is an export from 3ds MAX as .dwg. I would like further assistance on what I should do or if I have to fix something in order to use these commands. 

Kindly find attached my work, to actually try it out and maybe you can tell me what's wrong.

I appreciate any given help to further continue my project.

Thanks in advance,

R
