2.0 Installation Notes for AutoDesk Products
1) Run INSTALL from Disk #1 of the mach64 diskettes.
2) Select Drivers Installation from the Main Menu.
3) From the Install Enhanced Drivers menus select one of the following:
AutoCAD
Autodesk 3D Studio
AutoShade
4) Follow the screen instructions to completion.
5) When INSTALL reports that the driver has been successfully installed,
exit the install program.
6) All the AutoDesk products require environment variables to be loaded
prior to starting the application. The INSTALL program creates
batch files that contain all the necessary Set statements. These
batch files will be located in the directory specified during the
driver installation. The following are the default batch file names:
AutoCAD R10, R11 and R12 ADIACAD.BAT
AutoDesk 3D Studio R2 ADI3DS.BAT
AutoShade with Renderman ADISHADE.BAT
7) After running the appropriate batch file, refer to your Autodesk
documentation for information on how to select and reconfigure the
display driver.
****************************
3.0 Known problems:
1280x1024 is only supported at 8 bpp (256 colors) on ISA mach64 products.
24 BPP is not currently supported on ISA mach64 products at resolutions
greater than 800x600.
1280x1024 is only supported at 8 bpp (256 colors) on non-linear aperture
configurations
24 BPP is not currently supported on non-linear aperture configurations at
resolutions greater than 800x600.
AutoCAD Release 12
Configuring mode:
Selecting No when asked, KEEP CONFIGURATION CHANGE <Y>, does not restore
the old mode; it will actually change to the mode just configured.
Anti-Aliasing
DLX-Press command DLXAA (anti-aliasing) does not work.
24 Bit mode
Images rendered at 8bpp will cause the viewport to display white, when
viewed at 24bpp (display and render mode)
Viewport
Rendering a drawing to a Viewport, causes the cross hairs to turn red.
Configuring a mode, after a viewport render has occured will result in
the command prompt disappearing. The command prompt will remain invisable
until the screen is refreshed.
Reconfiguring Render Engine
After replaying a rendered file, a vertical bar appears
-----------------
AutoCAD 10
3D Constuction lines
Random lines appear after selecting 3D-Construction menu.
Copying objects may cause the orginal objects display a differenct color
Earlier versions of AutoCAD may require the phar lap extender patch,
newdx.exe and apatch.exe inorder to function correctly with the mach32
drivers.
-----------------
AutoCAD Rel 11
Drawing Order
Zooming may cause an ordering problem, where the drawing order of objects
may be reveresed. To correct the problem set WORLD SPACE PARTITION to NO
under the DIPSLAY LIST OPTION.
-----------------
AUTOSHADE
Saved File Format
Check marks, which indicate the format in which to save a file, do appear
when replaying a shade file. The last format you seleced, will not be
marked you will have to remember it.
-----------------
3D Studio
3D-Studio Release 3 is NOT supported by this driver. Please refer to
your 3D Studio Release 3 manual for further information regarding mach64
support.
3D Studio R3 is slow loading.
-----------------
3.1 3D Studio's 3DS.SET file
After installing DL-Xpress, you will need to modify the 3DS.SET file
located in your 3D Studio directory. These changes tell 3D Studio that
you are using DL-Xpress RCPADI driver. Once these changes are made they
will not need to be done again.
Use your favorite word processor (remember to save in text mode only!) to
make the changes described below. Please be aware that the line numbers
given are approximate, though they should indicate the general vicinity of
the parameter.
*** Rendering Driver
It is necessary to modify the Rendering Driver section of the 3DS.SET file
to set DL-Xpress as the default rendering driver. To do this change line
123 as outlined below:
Old line 123 (approx.):
DEFAULT-DISPLAY = "VGA300X200"
New line 123 (approx.):
DEFAULT-DISPLAY = "RCPADI"
Should you need to use a different rendering driver than Dl-Xpress,
you can select a new one from within 3D Studio by selecting Render,
Setup. Configure from the main menu and choosing a different display driver.
*** Main Display Driver
Next, set Dl-Xpress to be the Main Display driver. To do this, change
line 139 by removing the semicolon, as outlined below:
Old line 139 (approx.):
;MAIN-DISPLAY = RCPADI
New line 139 (approx.):
MAIN-DISPLAY = RCPADI
*** Materials Editor Driver
Finally, set Dl-Xpress to be the Materials Editor driver by removing the
semicolon in line 146:
Old line 146 (approx.):
;MATERIAL-DISPLAY = RCPADI
New line 146 (approx.):
MATERIAL-DISPLAY = RCPADI
