This is a text file for the CAD.BAS program located in DL4. I am wrote this text file after downloading and running this program on a 130XE and with DOS2.5 because i found the instructions on how to operate it and limits and to be a little skimpy. Not to be confused with command statements. asuming you have alreay down loaded and saved a copy of this program the fastest way to load it and run it into basic is to use the command RUN"Dn:FILENAME" this will load and automaticly run it.To use the menu commands a joystick has to be pluged into port 1.Then push OPTION to become familer with the commands. Select START NEW DESIGN answer YES OR TYPE Y then press RETURN. NOTE ALL KEYBOARD ENTRIES MUST BE FOLLWED BY RETURN TO CONTINUE EXEPT OPTION ALSO PRESS THE RETURN KEY WITHOUT ENTERING WILL RESULT IN THE PROGRAM CRASHING AND DESIGN/VALUES ENTERED WILL BE LOST. To restart the program just type run and press return OK NOW that i have said that, the computer prompts you for NUMBER OF CONSTRUCTION CIRCLES ? enter any number between 0-30 after pressing return you can select the DRAWING PAGE but to avoid confusion and possilble error in which your design would be lost we will goto the CONSTRUCTION LINES again you are prompted for a number enter any 0 TO ? .Ihave found no limit to this command.Well as you may already have figured out you are back at the menu if you want to you can enter ANGLE OF VIEW but not required at this point. OKAY FOLKS THIS IS THE MOMENT YOU BEEN WAITING FOR IT IS TIME TO DESIGN YAAAAA!!!!!!!!!!! select the DRAWING PAGE ok on the screen you will see to stright vertical lines and to the left a vertical line of dots these show at what point you are working on (NOTE the nuber of CONSTRUCTION CIRCLES you choose is = the number of dot in this line).To the left of the line dots is a single dot press the single dot press the fire button to see which dot i'm talking about, this indicates where the line starts. The stright line next to the dottted line we just dicussed is your left margin and the top,bottom and right margins are the screen edges. The right stight line this is your drawing line it bends and streches like a rubber band. To start press the fire button to select the point you wish design then use the joy stick to design,press the fire button to select a new point. Each time the dot reachs the top dot it updates the point so don't be suprised if some dots dissapear and the single dot bounces or goes up it's just going to the start of the line. As far as the designing part goes that up to you and a lot of practice trial & error When you are ready to for the computer to make it into a 3-D drawing after all that is what CAD stands for is COMPUTER ASSISTED DESIGN press START and if you entered CONSTRUCTION LINES,ANGLE OF VIEW it will start to draw your 3-D design if not it will return to the menu from there you enter these points. Then select DRAW CURRENT DESIGN After viewing press the fire button to return to the menu fom there you can change , view or both your current design ,but then maybe you might just want to start a new one. The one draw back of this program is there are no save/load or print routines built in this realy a bummer if make a design you are proud of. Well thhaats all folks if you have any questions or comments on this file drop me line on the BBS or in my mail box any other quetions on the program contact the designer Sam Small BYE YALL *********************************************************************** JASON KLEIN # [73260,502]
