In sol draw command , for sections it says 3d solid is empty and reject drawing . but in same drawing Elevations it works. please expiation why is that ?  

Hello mirinchige, to create sections from solids ( without touching the original solids ) I use the command SECTION from the model space that I define by selecting 3 points defining a plane and that create regions.Could it be OK for you ?To separate in two solids or erase one side of the 3 clics I use the command SLICE that will modificate your original solid.

O.k. Thanks
