II - TIPS/ERRATA/FEATURES/REVISIONS
============================================================
The following list includes new features and tips for this
version of TurboDLD-Classic and AutoCAD in general.
- The most important feature of TurboDLD-Classic is the addition of
a world view called The Big Picture(TM). Bringing up the Big Picture
allows you to view where in the current drawing you are currently located
in your active viewport, and it also gives you the ability to
dynamically move to another part of the drawing without having to
exit the function you're currently executing.
- The Big Picture update mode is now user selectable. Big Picture
Refresh in the User Interface menu can be set to refresh automatically
when an object is drawn or erased, or manually by issuing
a redraw or DLDREFRESH.
- The size of the image in the Big Picture can be zoomed
incrementally by using the "+" and "-" keys on the numeric
keypad. The "Home" and "End" keys will zoom the Big Picture
to the maximum and minimum ranges. The initial Big Picture
image size is dependent upon the size of the drawing and
the AutoCAD display space size being used.
- Disabling the TurboDLD drawing cache, DLDCACHE command,
will have detrimental performance results.
- The PMODELINE width is as large as possible given the
current screen dimensions and font character size. If less
area is desired, switch to a smaller font size.
- The DLDUSAGE command now gives TurboDLD-Classic usage down to the
exact number of bytes being used.
- DLDCOLOR can be run from within AutoCAD, instead of externally
as a separate utility.
- There is no longer a Remove or Overwrite mode for the Display
List. TurboDLD-Classic functions as the Remove mode did in previous DLD
versions, eliminating flashing of erased vectors, without affecting
performance.
III - TurboDLD-Classic Installation and General Information
===========================================================
What does it do?
================
TurboDLD-Classic's main function is to speed up AutoCAD pans, zooms
and redraws. The driver accomplishes this by creating and
maintaining a Display List - a fast-displaying vector list
of the current drawing - dramatically increasing performance
on pans and zooms.
What's the Catch?
=================
The only resource used by TurboDLD-Classic is memory. The driver
itself takes up about 35 Kbytes of RAM from extended memory,
which means it does not affect normal DOS operation. The
driver is loaded by AutoCAD at AutoCAD load time.
The Display List size can vary from one tenth to three times
the size of the current drawing file.
Thanks for the memory.
======================
You may wish to purchase and install additional RAM before
installing TurboDLD-Classic, since it shares memory with AutoCAD. If
AutoCAD is using a lot of memory, TurboDLD-Classic may not have
enough. If there is significant hard disk activity while
you are using TurboDLD-Classic, it may be an indication that you
should add more memory to your system.
AutoCAD R12 Installation
========================
For AutoCAD R12 setup, when installing TurboDLD-Classic into a
subdirectory other than \ACAD\DRV, you must edit the ACADDRV
environment variable to point to the TurboDLD sub-directory.
For example, if TurboDLD Classic was installed into a sub-directory
on drive C: named TURBODLD, the ACADDRV environment variable would
look like the following:
SET ACADDRV=C:\ACAD\DRV;C:\TURBODLD
Run FASTACAD.BAT in the subdirectory you installed TurboDLD-Classic
and then start AutoCAD.
Begin AutoCAD with the reconfigure switch by typing
ACAD -R
Choose option 3, Configure Video Display from the AutoCAD
configuration menu.
Type 'Y' at the "Do you want to select..." message to display
the available video options for AutoCAD.
Select TurboDLD-Classic by Panacea from the list of display options.
Continue installation at the Driver Configuration section below.
AutoCAD R10/386 and R11/386 Installation
========================================
Run FASTACAD.BAT in the subdirectory you installed TurboDLD-Classic
and then start AutoCAD.
Reconfigure AutoCAD to use TurboDLD-Classic by selecting option 5,
Configure AutoCAD from the AutoCAD main menu. From the next
menu, select option 3, Configure Video Display. Choose Item
1, P386 ADI 4.0/4.1 as your display device (for more
information, see the AutoCAD "Installation and Performance
Guide"). Continue with the Driver Configuration section below.
3D Studio
=========
To install TurboDLD-Classic with 3D Studio 1 & 2:
1. Run PANA3DS.BAT in the subdirectory you installed
TurboDLD-Classic.
2. Next, edit your 3D Studio 3DS.SET file found in the 3D Studio
sub-directory.
**** If you are using 3D Studio Rel 1, you need to find the line
that starts with DEFAULT-DISPLAY. You want to modify it so
that the line reads: DEFAULT-DISPLAY="RCPADI". Also, do the
same with the line that starts with MAIN-DISPLAY, except that
you should omit the double quotes around the RCPADI
(i.e MAIN-DISPLAY=RCPADI). Make sure to remove the ";" (semi-
colon) in front of these lines. Also, if you selected to use
the 256 color VGA driver during the setup, you may change the
MATERIALS-DISPLAY line in the 3DS.SET as well. Save your
changes and you're ready to use 3D Studio.
**** If you are using 3D Studio Rel 2, you need to find the line
that starts with RENDER-DISPLAY. You want to modify it so
that the line reads: RENDER-DISPLAY=RCPADI. Also, do the
same with the line that starts with MAIN-DISPLAY
(i.e MAIN-DISPLAY=RCPADI). Make sure to remove the ";" (semi-
colon) in front of these lines. Also, if you selected to use
the 256 color VGA driver during the setup, you may change the
MATERIAL-DISPLAY line in the 3DS.SET as well. Save your
changes and you're ready to use 3D Studio.
3. In the 3D Studio sub-directory you will need to delete or
rename the 3DADI.CFG file. This will allow for the
TurboDLD-Classic to be configured upon executing 3DS.
AutoShade
=========
If you are using AutoShade 2.0 with Renderman, first run the modified
FASTACAD.BAT as stated above in the 3D Studio directions. Then you can
configure AutoShade by changing into the AutoShade sub-directory and
type SHADE/R. For the display device, select P386 Autodesk Device
Interface display driver. And for the rendering display, select the
P386 Autodesk Device Interface rendering driver. If you are running the
display and the rendering screen on the same monitor (i.e. single
monitor), make sure to tell AutoShade this. A single monitor approach
will require a redraw of the display screen after a rendering screen.
Driver Configuration
====================
After selecting TurboDLD-Classic, P386 or RCPADI as the display device, the
TurboDLD-Classic Driver Configuration menu will appear.
Set-up of TurboDLD-Classic requires configuration of the various
operating parameters of the driver. These parameters have
been logically grouped into menus based on their interaction
with AutoCAD. A quick trip through each menu will complete
the configuration process.
The following is a summary of each of the driver
configuration menus.
Select Graphics Board/Resolution
Configures TurboDLD-Classic for the graphics board
display and rendering resolutions to be used.
Always select XGA as the graphics board and a desired
resolution.
Basic Configuration
Sets AutoCAD screen characteristics, number of text
lines in the command-line area, font size and display
mode.
User Interface
Configures parameters for maneuvering within AutoCAD.
Includes, digitizer button controls, edge panning
characteristics, and pop-up menu definitions.
Expert Configuration
Configures operation of TurboDLD-Classic itself. This menu
allows for customization of the driver for maximum
speed or to configure it for memory constraints.
After all parameters have been set, scroll down to the Save
and Exit option and press the F10 key to continue.
Next, configure the standard AutoCAD screen display
characteristics and then type 'Y' to accept the changes.
Enter '0' to exit to the AutoCAD drawing editor.
Color Configuration
===================
The final step in setting-up TurboDLD-Classic is to configure the
colors for AutoCAD. From the AutoCAD Command Line, type
DLDCOLOR, to start Custom Colors, TurboDLD-Classic's color
configuration utility. Make the desired color changes and
then Save the new color palette and then Exit to return to
the drawing editor.
IV - TurboDLD-Classic Commands
============================================================
DLDBIGPIC
==========
To call up the Big Picture, at the AutoCAD command line,
type DLDBIGPIC, or double click the right mouse button or
button 2 on your digitizer puck. (if you haven't redefined
your Button 2 double click function). This will bring up the
Big Picture on the display. You will see crosshairs and a
highlighted section which indicating which part of the whole
drawing you're currently viewing - initially the whole Big Picture
will be highlighted. The selection or pick box will have an "X"
through it. Move the mouse/digitizer around to locate your pick
box. If you can't see a small box moving, click the left mouse
button (the pick button) to size down the pick area. In size mode,
the pick box will have a right pointing arrow in it ("-->"). If
the Big Picture is too small to work with, you may increase the
size of the image in the window by pressing the + key on your
numeric keypad. Likewise, pressing the - key will reduce the size
of the Big Picture. Pressing the HOME and END keys will put the
Big Picture into its smallest and largest size, respectively.
The Big Picture pick box is always scaled to the proper aspect
ratio for the current viewport. Clicking the pick button again
will put you back into the pick box move mode ("X"). This
operation is very similar to using the Zoom Dynamic feature
of AutoCAD. Once you have positioned the pick box on the
area you would like displayed in the active viewport, click
any button other than the pick button to initiate the zoom,
or press the Enter key. If you want to abort the operation,
just hold any button down, other than the pick button, until
the Big Picture disappears. You can also hit any key on the
keyboard, other than Enter, to cancel the Big Picture. Note
that the Big Picture is updated with new drawing commands,
but that moves or erases in the Remove mode will not update
the image. A DLDREFRESH or a REGEN will update the Big Picture
with the current drawing changes.
DLDBPCACHE
==========
Enables or disables the Drawing Cache for TurboDLD advanced
features. This cache speeds up pans, zooms and redraws when
using TurboDLD's advanced features, real-time panning,
ZoomPreview, etc. DLDBPCACHE is normally enabled. Disable
this feature in low memory situations.
DLDBPDIM
========
Resizing and repositioning the Big Picture can be accomplished
by typing this command at the AutoCAD prompt. DLDBPDIM allows
you to tell the driver where you want the Big Picture placed and
how large you want it to be. The size is limited to being
between one-quarter and one-half the width of the display.
This command functions like the pan/zoom selection box in
the Big Picture, as far as positioning and dimensioning goes.
To abort, hold the right mouse button down until the moving box
disappears.
DLDBPFREEZE
===========
Sets the Big Picture zoom definition area display options.
Toggles between Freeze and Float. Freeze will lock the zoom
definition area to the middle of the bird's-eye view, moving
the drawing around the window when a zoom occurs. Float will
keep the bird's-eye drawing in the same location and move the
zoom definition area within the bird's-eye.
DLDBPHILIGHT
============
Changes the highlight mode used to display the Big Picture.
Alternates among three modes, Patt Line, XOR Rect, and Both.
Patt Lines will use dotted lines to form the Big Picture, XOR
Rect will use a contrasting rectangle to highlight the area.
Both will use a combination of Patt Lines and XOR Rect.
DLDBPREFRESH
============
(Actual acad command to type is DLDBPREFRSH).
Toggles the Big Picture update mode. When enabled, DLDBPREFRSH
will cause the Big Picture to refresh automatically when an object is
drawn or erased. If disabled, the Big Picture is updated manually by
issuing a redraw or DLDREFRESH.
DLDBPSTATIC
=============
Toggles DLDBIGPIC to stay on the screen at all times. Use this
command if you want the Big Picture on the screen in order to
conveniently move into it whenever you want. Typing DLDBPSTATIC,
will put up the Big Picture at the position you set with DLDBPDIM.
Note that the static Big Picture will disappear when other menus
pop-up on the screen, and it will also disappear if you draw any
objects which may overwrite the Big Picture. With these exceptions,
the Big Picture will remain on-screen until you either exit the
drawing screen or you type DLDBPSTATIC again.
DLDCOLOR
========
Invokes Custom Colors, Panacea's color configuration program.
DLDCOMPACT
==========
Returns unused display list memory back to the AutoCAD memory pool.
DLDDCACHE
=========
This command toggles the TurboDLD's internal drawing cache
on and off. DLDDCACHE is an AutoCAD-wide compressed form of the
current viewport which speeds pans, zooms, and redraws.
DLDDLIST
========
This command toggles the display list function of TurboDLD
on and off. Please note that if the display list is turned off,
you will be running AutoCAD as though you were using a
standard non-display list driver: pans, zooms and redraws
will be much slower with DLDDLIST disabled.
DLDECHO
=======
Toggles internal TurboDLD command echoing at the AutoCAD
command line. DLDECHO also enables/disables echoing of menu
and button commands.
DLDHELP
=======
Provides a one-line summary for every TurboDLD command. It's
recommended that you flip to the text screen to view the
output.
DLDREFRESH
============
Refreshes the Big Picture to reflect the most current
changes to a drawing. If the static Big Picture is up,
it will be updated. If not, the next time the Big Picture
is brought up, it will contain a current representation
of your drawing, provided no changes were made between
the DLDREFRESH command and the DLDBIGPIC command..
DLDSTAT
=======
This command displays the current TurboDLD status.
DLDUSAGE
========
Use DLDUSAGE if you want a to-the-byte breakdown of how
memory is being used, specifically for display list
processing (i.e. split between the display and fast-redraw
lists). DLDUSAGE returns information about how much EMS and
Extended memory is still available, and how much memory each
viewport is occupying. Since AutoCAD can support multiple
viewports, it is possible to have multiple display lists.
DLDVISREGEN
===========
Toggles between the Fast and Visible Regen modes of TurboDLD.
A Fast Regen will create the display list and then display the
drawing quickly, all at once. Visible regen will display the
drawing in "chunks" as the display list is created. This command
is a dynamic form of the Regen Mode parameter in the Expert
Configuration Menu.
DLDVER
======
Displays TurboDLD version, serial number and registered
user's name.
