HelloA few weeks ago a started to use autocad 07, and I have a little problem. I builded a block formed by a glass cube + black edges + arrow inside the cube (very easy...i know!). The problem is that I can not use this block as a 3D solid and i can not make other operations such as the intersection with an other 3D solid. Could you tell me how I can do it please? Could I transform the block in a 3D solid?Thank you Gaspare

 
 Welcome to CADFORUM.
 
 Was this  build in the Isometrics way ?

I'm not an expert.However, I made this block in the 3D-area with assonometric view.

 
 I mean you have build it with 2D commands .

Thank you very much for the advise, but never change!Do you know how i can build the object described above without create a block, please. If you want i can send you the block

 
 Ok send the block in arben.allaraj@gmail.com or as image here.

Does it matter if it is solid or not? I always keep things in pieces, as many as is efficient that is. 

 Hello gaspar
 
I saw the your drawing and I am not sure excalty which block do you want to change but i can say.You should the ways below.
 
Type Command :bedit in command window
Your blocks are build in 2D to transform them in 3D use Extrude command.
and save it.
 
Write me again if you don't understand.
