This READ.ME file contains information about ProtoCAD 3D that did not
make it to the printed manual of Ver. 2.00. It also lists the files
distributed with Ver 2.00, and explains how to upgrade from previous
versions.
Please READ THIS FILE THOROUGHLY! It contains very important
information, and reading it now will probably save you time and
trouble later on!
You can print this file by COPYing it to your printer with the
following command:
copy READ.ME prn
If you want to look at the other On-Disk ProtoCAD 3D documentation,
see the file list below, which lists all of the documentation files,
and see the section on the On-Disk User's Manual.
Shareware is NOT Freeware!
Evaluate the shareware copy program for 30-days and give copies to your
friends for evaluation. If, after the 30 days, you continue to use the
program, then you need to pregister it by sending us the registration/order form
included in this help file or by calling 800-468-7487 (Orders Only!).
You will receive the Latest version, Printed manual, 90-day free
Technical Phone Support, BBS Technical Support, Newsletter, and Reduced
price Upgrades.
In addition to that, the 'UNREGISTERED COPY' message will be
eliminated from the screen and a tool bar with the most frequently
used commands will take its place. Registering will also get you the
capability of using external script files to create series of TGA and
PCX files for animation sequences. And, of course, it will get you the
legal license to use the software beyond the 30-day evaluation period.

On-Disk Documentation
~~~~~~~~~~~~~~~~~~~~~
The installation process extracts a file called PC3D.MAN. This is a
ready-to-print formatted, User's manual for the program.
Following the installation, make sure that the PC3D.MAN file is
indeed on your default directory. Then, to print this manual:
(1) Make sure that the your printer is ON and there is enough
paper in it (the manual is about 100 pages).
(2) From the DOS prompt, type
COPY PC3D.MAN PRN and press [ENTER]
Note that if your printer is connected to a SERIAL port,
then you need to use the command COPY PC3D.MAN COM1, or
COPY PC3D.MAN COM2 (depending on which serial port your
printer is connected to).
NOTES/ADDITIONS TO THE USER'S MANUAL
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1. When a new view is selected, an image extents scan is made and the
image is placed in the center of the screen (similar to performing
an Image, All command), if the Auto Ctr toggle is ON.
2. Identifying reference marks are placed in the center of facets. This
is particularly useful when trying to change the surface normal, since
it permits you to select uniquely identified facets.
3. The limit on the number of points that can be accommodated when
importing a WAV file, was increased to 8000.
4. VGA 256-color and VESA color mapping is done using a 3,3,2 model,
i.e., 3 bits are used for Green, 3 for Red and 2 for Blue. Since
there is not enough resolution (2 bits) for Blue, you might
experience blue patches when rendering an 'almost' gray scale image.
If that happens, select the Gray option in the Render sub-menu.
5. When rendering in 256 colors, the edges are NOT visible regardless of
the setting selected in the Render, Edges sub-menu.
6. The trackball employs an effective 'gimbal lock' mechanism. If the
image is rotated/rolled beyond a 90 degree angle, the Yaw angle
automatically switches by 180 degrees.
7. As the observer distance (D) is reduced, and you move closer to the
center of the image, you will observe some clipping of polygons that
are effectively behind the focal length plane. This normally occurs at
about D=0.5. You might need to render the image to re-orient
yourself.
8. When attempting to print without EMS, the 32k-48k shadow buffer is
used by the Z-buffer model to internally render the image in
horizontal strips. Since the buffer size is limited, the longer the
strip (specified print width) the narrower the vertical strip size
that can be accommodated. When the calculated vertical size falls
below 16 scan lines, the program will not render and will abort the
printing process. This limit will accommodate a 7.5 inch width at
120 dots per inch resolution. Under these conditions, if you want to
increase the resolution, you'd have to reduce the specified print
width. For above example, if you wanted to use 240 dpi resolution,
the specified width should be approximately 3.75 inches.
9. When creating TGA output files, the program requires approximately
300k of EMS to render the image. If it's not available, the TGA
output menu is disabled and an appropriate error message will be
issued.
Modifications in Release 2.00a
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1. The {smooth_triangle....} option was implemented for POV output
files, for all mesh type objects on layers 17-32 (spheres, extrusions,
etc.) This results in a smoother transition from facet to facet
using the average sufrace normal of each facet bordering the
vertex. (No such smoothing takes place on layers 1-16).
2. The {bounded_by.....} option was implemented in the POV output
files. This results in a significant decrease in rendering time.
The {composite...} command is now used to group related objects
rather the {object...} command. This was necessary in order to
make the {bounded_by...} command operational.
3. The observer point coordinates, in the POV output file, are now
reflective of the user selected observer coordinates.
4. The observer point coordinates, while viewing an image in ProtoCAD,
are now reflective of the user selected observer coordinates.
5. If you are using later versions of the POV program to ray trace
images created with ProtoCAD, then the +mv1.0 command line
switch should be used (The command structure in the ProtoCAD created
files conforms to ver 1.x of POV - see POV documentation for
additional information).
6. A correction was made to the File, Config, Printer menu, to ensure
that the printer driver selected by the user would stay selected
after the menu was exited.
7. The on-screen "control cube" speed is now controlled by the SPDUP
parameter under the File, Config, Default menu. The default value is
2 which should be fine for most users. Increasing the value speeds
up the control cube movement, while decreasing it to 1 or 0 slows it
down for pin-point viewing accuracy.
Modifications in Release 2.00b
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1. A modification was made to correct the EMM386 exception error when
importing a DXF file because of stack overflow. Modules were
rearranged so now stack space available for each call is doubled.
2. A modification was made to the DXF Export module, for 3D entities, so
that the extraneous Type 13 information, required when importing to
AutoCAD, is now added to the exported file.
3. A significant modification was made to the memory management modules
which resulted in the following three modes and appropriate
enhancements.
a. Screen update speed was increased by up to 100% (in wireframe
mode) and by up to 20% when rendering. The actual speed depends
on the specific design, the amount or RAM available, etc. In this
mode, the program consumes more RAM. It should be noted that if
you don't have enough Expanded Memory (EMS), the program can take
up to five six times longer for a screen update, regardless of
the mode yo are in!! It is recommended that at least 2 Mb of
EMS is available before you start the program.
b. If speed is not of importance, but memory is premium, then start
the program with the /MIN command line switch i.e., PC3D /MIN
[ENTER]. (The /MIN switch was not active in earlier releases, but
it IS active NOW.) This would make maximum amount of memory
available to you (MINimize memory usage), at the expense of screen
update slowdown.
c. In earlier versions, memory consumed by placing data into a buffer
during edit operations, was NOT returned to the pool, and
eventually, the user might run out of memory, even though the
model size (# of elements), did not change significantly.
With the new memory module, the memory used for the edit buffer is
freed and returned to the pool when the File, GetInfo command is
executed. However, the option to clear this memory, or not, is
controlled by the user through the toggle FREEMAN (under the File,
Config, Default menu). If FREEMAN is toggled ON, then the memory
is freed every time File, GetInfo is executed.
