thank you reynand,
i appreciate your respond, but let me to inquire about some small things :
i'm modelling a multistory bldg. the floors planes were imported from autocad , and i want to draw the shell or area on autocad as a one unit
1- The command to do this is 3D-face as sap2000 isn't it ? I read at an book that we draw a pline around the slab periphery at a layer say floor , if i did this i don't need to draw 3D surface ?
2-If i drew the shell area at etabs all over the plan , i tried to mesh it at frame elements positions (there are inclined ,vl and hl lines) but no thing happened , how i can do this ?
thank you again.
ahh, i forgot
i want to mesh the area with frames to delete the excess areas from plan.
