Problems with lines showing in my solids

[Anonymous]

Hi everyone,

I'm having troubles with my autocad 2019, for some reasons, the solids became with a grid inside at some point.

I'm also have trouble (30prct of the time) when I use Move, stretch and extrude command.

Does anyone had this problem before?

Hi, 

Thanks for your help

Looks like two of your objects were created with a mesh surface (sections of planes), all the others are made with a single region each. You are seeing what these are made of basically

Yes , but I made them in the very same way, 

Now when I copy it and paste it into an other drawing, then I don't see the line . So I guess the drawing must be corrupter. 

Have a look at the screenshot
