- In command prompt type GROUP, select all the elements and group them
step 6: Creation multi-storey
- In command prompt type COPY, by selecting the bottom corner by snap object and placing over the top corner and done this for three times
- In command prompt type UCS, by placing ucs for the best view
- In command prompt type REC, create rec of dimension length, width as 4",9" at two corners at the top
- In command prompt type EXTRUDE, extrude the created rectangles to 5'-5"
- In command prompt type UCS, for better view
- In command prompt type REC, create the rectangle by selecting the corners of newly created rectangles
