1 Introduction
=================
1.1 BigFocus 13/Win General Information
----------------------------------------
Welcome to BigFocus 13/Win, SPEA's acceleration driver for
AutoCAD 13 for Windows and Windows NT! This software is simple to use and
offers a number of attractive features:
- performance boost up to factor 10 of the standard AutoCAD display
drivers
- a new SPEA Toolbar which contains the main features of the driver:
+ Bird's-Eye View
+ Zoom All function
+ Spyglass Lense
+ Redraw function
+ Zoom Window function
+ SPEA Hotkeys configuration
+ BigFocus 13/Win online help
- effective mouse-controlled zoom and pan actions via the Bird's-Eye
View
- Spyglass window enabling close-up views of the drawing and transfer
back to AutoCAD
Note that the driver does not contain any 3D functionality. This
can be purchased with the 3D-World package (which contains '3D-Win', a
hardware-independant 3D-Viewer for Windows).
1.2 System Requirements
-----------------------
(a) Boards
The BigFocus 13/Win driver is hardware independant - it can therefore be
used with any Windows accelerator! It is also optimized for use with
graphics boards which incorporate an S3 or Weitek P9100 graphics
processor.
(b) PC + Memory
To use AutoCAD and BigFocus effectively you will need a large amount of
memory and a large Windows swap file. Special information on this topic
is described in the AutoCAD 13 for Windows documentation and in the
corresponding Autodesk forum in CompuServe.
(c) Windows
The current version of this software is for Windows 3.1x, Windows for
Workgroups and Windows NT 3.5 only.
1.3 Software Registration
--------------------------
This software need not be registered for use with one of the following
SPEA graphic boards: V7-MERCURY series board, FIRE, HiLite and FGA860GX
and V7-STORM PRO.
It can also be used with other SPEA boards and any other Windows accelerator
(independant of the manufacturer) AFTER REGISTRATION and entering the
registration code key.
Registration information is automatically shown on the screen. It fills out
the enclosed form REGISTER.TXT which can then be used to register the
software (please refer to that file for details).
2. Installation and Configuration
==================================
a) Installation from floppy disk
--------------------------------
1. Start Windows and the Program Manager.
2. Select the menu items 'File' and then 'Run'.
3. Select A:\SETUP.EXE.
4. Click on 'OK' and follow the instructions on the screen. The
installation routine will decompress and copy various files onto your
harddisk.
b) Installation from CD ROM
---------------------------
1. Run the program SPEAINST from the CD ROM
2. Select 'SPEA Software Products'
4. Follow the instructions on the screen. The installation routine will
decompress and copy various files onto your harddisk.
Configuration
-------------
An important file will also be created on your hard disk:
DSBIGFOC.INI.
DSBIGFOC.INI contains an important entry that you may need to change
to accomodate for your hardware (see 'GDIByPass' below).
Reconfiguring AutoCAD for Windows to use BigFocus 13/Win:
Start ACADWIN, Select "Options", "Configure", and when selecting the
display driver choose:
SPEA BigFocus - Accelerated Display Driver by SPEA AG
3. Release Notes
==================
3.1 GDIByPass
--------------
During the software installation a file named DSBIGFOC.INI is created in
the directory you enter when installing. It contains the following section:
[display device]
GDIByPass=3
This entry controls both the operating mode of the BigFocus 13/Win
software and hardware accesses to the graphics board installed. It is
vital to the speed of the driver's operation. The Windows GDI (Graphics
Device Interface) is a standardized but generally slower software solution.
The GDIByPass entry controls whether BigFocus 13/Win uses the GDI or not.
Explanation of GDIByPass values:
Windows GDI Bypass: Hardware access:
---------------------------------------
GDIByPass=3 ON ON (default)
GDIByPass=0 OFF OFF
The default setting is GDIByPass=3 because this is the fastest operating
mode. If you should experience problems with BigFocus 13/Win then
change the entry in DSBIGFOC.INI to GDIByPass=0 to eliminate these (see
also BigFocus 13/Win online help 'Troubleshooting' for more detailed
information).
4 Troubleshooting
====================
Problem:
Boot problems, Windows General Protection Fault report (system crash)
after installation.
Solution:
Edit the file DSBIGFOC.INI in the BigFocus 13/Win installation target
directory. It contains the following section by default:
[display device]
GDIBypass=3
Change the value for GDIByPass to 0.
Problem:
During the AutoCAD configuration the option 'SPEA BigFocus - Accelerated
Display Driver - by SPEA AG' doesn't appear, the SPEA Toolbar doesn't appear.
Solution:
Check the file DSBIGFOC.INI in your BigFocus 13/Win installation target
directory. It should contain the following section (example):
[environment]
GDC=c:\spea\bf13win
whereby the path (C:\SPEA\BF13WIN in this example) must correspond to your
installation target directory. Alter or add the entries if necessary.
Also check your ACAD.INI file. It must contain the following section (example):
[General]
....
....
ACAD=c:\acadr13\win;.....;C:\SPEA\BF13WIN
ACADDRV=c:\acadr13\win\drv;C:\ACADR13\WIN;C:\SPEA\BF13WIN
....
whereby the SPEA path (C:\SPEA\BF13WIN in this example) should correspond to
the target directory you entered during the software installation. Change or
add the entry if necessary.
