Here is the main code that i would like to use on my code to create the vehicle.

;;;
;;; OVERVIEW
;;; BuildVehicle.LSP draws attributed blocks of vehicles that are required
;;; by Tturn.lsp, for approximating the paths of trucks as they drive.
;;;
;;; GETTING STARTED
;;; Load and run BuildVehicle. It will ask you for all of the parameters
;;; for your vehicle, and draw a unique attributed block. You can build a library
;;; of vehicles for future use. BuildVehicle.lsp runs using "BV" or "BuildVehicle"
;;; from the command line. Axles should be the "centroid" of any group of multiple
;;; axles.
;;;
;;; Data for turning angles and time to turn is for future use, so enter
;;; dummy data if you do not know it.
;;;
;;; enter "N" for no trailer, but still give place holder data for the non-existent
;;; trailer. It will not be drawn.
;;;
;;; The parameters are used to build a scale block of the vehicle you are
;;; defining, which is made into a block.
;;;
;;; You can change the attributes in the block if you make a mistake, but the block
;;; itself does not change size (it is not parametric).
;;;
;;; If you make a new block with the same name as an existing one, it will overwrite
;;; the old one, or perhaps fail. If this happens, erase all errant blocks, and purge
;;; the old block from the drawing file.
;;;
;;; Draw the path for the vehicle as the route taken by the front left tire. A future
;;; version of this program might add path by centre or by right side of vehicle, to
;;; suit other driving standards.
;;;
;;; After running Turn, manually adjust the route to move the vehicle off of collisions
;;; and then run turn again to see if you now can drive the route.
;;;
;;; Remember, there is almost no error correction in this program. If you enter
;;; impossible geometry, the program will happily draw it. Please report issues and
;;; requested functionality to the author.
;;;
;;;
;;; REFERENCE
;;; Vehicle dimensions (ft) Min. Outside Min. Inside
;;; Vehicle Width WB1 WB2 Rad Rad. (check)
;;; P (passenger) 7 11 24.0 13.8
;;; SU (single truck) 8.5 20 42.0 27.8
;;; BUS 8.5 25 42.0 24.4
;;; WB-40 8.5 13 27 40.0 18.9
;;; WB-50 8.5 20 30 45.0 19.2
;;;
;;; Development Notes:
;;;
;;; 1) implement better error correction
;;;
;;; 2) collect and share correctly dimensioned standard vehicles
;;;
;;; 3) revise to not require data for non-existent trailers, and to allow multiple
;;; trailers
;;;
;;; 4) revise to draw tires centred on the tire paths
;;;
;;; 5) 080205 imperial scaling issue resolved, and input for dimensional information
;;; revised to allow picks from drawing
