Ulstad (3-D CAD author) and the COMPUTER SQUAD in 1985.To aid "=}user friendliness" S*P*A*C*E has enhanced the orginal disk with the addition of the following: - Atari DOS 2.5 files: =} DOS.SYS, DUP.SYS, and RAMDISK.COM (130XE RAMdisk) - Disk Menu (AUTORUN.SYS) - Documentation Reader (HELP=}.BNL) - This documentation (DOC.000) - The S*P*A*C*E logo screenWARNING:The 3-D CAD program (in compiled BASIC) is=} rather complex and the screen prompts are not always clearly understandable to first-time users.Therefore, you are urged t=}o read (actually, study) the instructions below prior to using.The following program limitations/peculiarities have been no=}ted: - The printout feature works only with an Okimate 10 printer. - Attempts to draw beyond the screen boundary caus=}e an error condition which will immediately exit you from the viewing or update screen and return you to the main menu. Redu=}cing the picture's scale (size) or its offset from the center of the screen will fix this problem. - There is no disk dir=}ectory to tell you what 3-D pictures are on the disk. You can press RESET to go to DOS to accomplish this. However, this wi=}ll disable the built-in RS-232 handler and undo the ability to send or receive pictures via modem (unless a complete system "=}re-boot" is first accomplished).INSTRUCTIONS: (A major rewrite of the original instructions, which are contained in disk =}file "DOC.TXT").BOOTING:--------1. Insert diskette into drive #1 and power up computer without BASIC (XL/XE users need =}not hold down the OPTION key - BASIC is automatically disabled by the disk menu program).2. From the disk menu select: A=}. "CAD3D" to load the 3-D CAD program. B. "HELP" to load the documentation reader to view or printout this text. Press RE=}SET (force a reboot) to exit back to the disk menu.3-D CAD OPERATION:------------------A. After the title screen appear=}s press OPTION for the main menu.B. MAIN MENU OPTIONS. 1. CAD or draw mode (NOTE: the existing screen is cleared from m=}emory when this option is selected!) General ------- a. Up to 240 coordinate points may be plotted (a line req=}uires 2 points). b. Cursor starts at 0,0,0 (X,Y,Z) c. Joystick #1: 1) left, right, up or down moves curs=}or (in units of 4). 2) Up & right enters ERASE Mode. d. START decreases Z. e. SELECT increases Z (units =}of 8). f. OPTION - return to Main Menu. Drawing Mode ------------ a. Position cursor at desired X,Y,Z. =} b. Press FIRE to set first point. c. Move cursor to next point. d. Press FIRE to set second point and to dra=}w line. e. Coordinate Display (bottom of screen):X, Y, Z, 0or1, MEM.used (0-240) ^ ^ 1st or =}2nd point # of points in curr line seg used so far f. NOTE: Connecting the end points of line segments saves me=}mory (coordinate points)! For example:.______._________._____________.___. This uses 5 points.._____. .________. ._______.=} ._____. This uses 8 points. Erase Mode ---------- a. Enter mode by moving joystick UP and RIGHT. b. Coo=}rdinate Display (bottom of screen): SEGMENT NO. Z1,Z2 c. Move joystick UP or DOWN to select desired line se=}gment. d. Press FIRE to erase. e. Exit Back to Drawing Mode by moving joystick DOWN and LEFT. f. After eras=}ing lines, SAVE and reLOAD picture file to recover full memory. g. NOTE: If deleting lines from a good "master", it is =}wise to SAVE the picture using a unique filename BEFORE ERASING LINES. Print Mode ---------- a. If an Okimate =}10 printer is on line, press START to enter mode. b. A small cursor will appear in the upper left corner of the screen.=} c. Use joystick to position the cursor at the upper left corner of the desired print window, then press FIRE. d.=} The cursor now jumps to the lower right corner of the screen. e. Use joystick to set the lower right corner of the pri=}nt window, and press FIRE. f. Press START to begin printing. 2. UPDATE or edit mode (same as the CAD mode, #1 above=}, except that the picture remains intact for editing). 3. VIEW or perspective mode a. Enter the angles of rotation =}about the X, Y, and Z axis. b. Enter the SCALE of the object/picture. c. NOTE: A RETURN with no entry or entering=} too large a scale will cause an exit back to the Main Menu. d. After picture has been drawn press OPTION to return to =}the main menu. e. Press SELECT to dump the picture to the RS-232 device (transmit via modem). f. Press START to d=}ump the screen to an Okimate 10 printer - follow the Print Mode instructions in 1. above. 4. REFLECTION mode. a. En=}ter the axis to be REFLECTED. b. NOTE: This mode produces an additional set of lines and doubles the memory (number of =}points) used. 5. OFFSET mode. a. Enter the axis to be OFFSET. NOTE: This moves the table of points left, right, up,=} or down. b. Enter the amount of OFFSET (0 to 200). 6. SCALE mode. a. Enter the axis to be SCALED. NOTE: This=} scales the table of points about one or all three axis. b. Enter the amount of SCALE. Examples: 1) A scale o=}f 2 doubles the size of the object. 2) A scale of .5 will half the size of the object. 3) A scale of -1 wil=}l flip the object about the X axis. 7. DISKETTE mode. Enter the appropriate file spec (i.e. "D:FILENAME.EXT") to LOAD/SA=}VE/MERGE any picture. 8. TRANSLATIONS mode. This functions like the VIEW mode, but the points are rotated in the table, =}not on the screen. 9. PARAMETERS mode. Options: 1. ASPECT RATIO. This has to do with the shape of the pixels. =} a. Pre-set to .85 (most monitors use between .8 and .9). b. Use 1.25 for printer. c. To check your s=}creen, draw a perfect square say 40,40. Then view it at 45,90,0,1. If it no longer looks square then change the ASPECT RATI=}O. 2. VIEW POINT. Your viewing point can be moved in or out (DEPTH), left/right (LR), or up/down (UD): a. DE=}PTH: set between -500 and 200 (near to far). b. LR/UD: set between -100 and +100. 3. RS232 WINDOW. a=}. 1 = ON, 0 = OFF. b. SIZE (set to): 1 to 128 pixels square. 4. PRINT WINDOW. Display/Input: a. "1" (=}ON) - print frame. b. "0" (OFF) - don't print. 5. MEM. CHECK. Displays system free memory. Does not change!=} 6. RETURN to MAIN MENU.C.
