<h2>Settings:</h2>
Preferences for Print command and Browser are read from file {base}/cfg/xa.rc
Default paths (menu - Standards -> Directories):
Directories accessed with File/Open are defined in the file {base}/xa/dir.lst
(Format: "symbolic base name | full path name / filename").
Default values for Z-buffer size, model size, Text Sizes are
in file {base}/xa/gCAD3D.rc.
These are set with menu
Standards -> Tolerances
Standards -> text
The setup file for the PostScript output is {base}/xa/psv.setup.
____________________________________________________________________________
<p><a name="Tolerances"></a></p>
<h2>menu Standards -> Tolerances</h2>
Tolerances will automatically tolerances derived from the
(maximum) Model Size.
<b>Modify</b>
The entire model is recalculated immediately.
<b>Reset</b>
The values are reset to the values defined in file <base>/xa/gCAD3D.rc).
The room size (default is 500 mm) is used to calculate the tolerances
(Curve representation, Identical-point tolerance, etc).
Room size changes at 10m:
MODSIZ 10000
The default value is in the file {base}/xa/gCAD3D.rc.
____________________________________________________________________________
<p><a name="Text"></a></p>
<h2>menu Standards -> Text</h2>
This allows the default text sizes, and a scaling factors to be defined.
The default text size in Notes is active when no explicit text size is defined.
<b>Modify</b>
The entire model is recalculated immediately.
<b>Reset</b>
Predefined values are in file <base>/xa/gCAD3D.rc).
The font size for text and dimensioning is defined by
DEFTX Textsiz {>} {text {DimTextSiz General Scale} {}
The number of decimal places is set interactively or in menu Standards -> text.
The default values are in the file {base}/xa/gCAD3D.rc.
____________________________________________________________________________
<p><a name="stdcol"></a></p>
<h2>menu Standards -> Color</h2>
Defines default color.
____________________________________________________________________________
<p><a name="Linetypes"></a></p>
<h2>menu Standards -> Linetypes:</h2>
The linetype table is defined in the file {base}/cfg/ltyp.rc
It is modified by editing the above file with a text editor. Additional linetypes
may be defined up to a maximum of 50.
This table is valid for all sub-models currently loaded.
This table is not stored with the models: in the model,
only the table index is stored.
Example:
Line Type 2 (G2): black, thin dashed lines; ltyp.rc to file with:
2 0 2 1 // Index 2, Color standard (0 = black), Type dashed line (2)
// Standard line thickness (1 = thin)).
The original data is in file {base} / xa / ltyp.rc.
Example:
0 0 0 1 // Normal Typ_Att_PT
1 1 0 1 // text Typ_Att_def
2 0 2 1 // dashed Typ_Att_go
3 0 1 1 // dash-dot Typ_Att_rp
4 11 0 1 // faces1 thick1 Typ_Att_Fac
5 1 3 2 // faces2 thick1 Typ_Att_Fac1
6 13 0 1 // faces3 thick1 Typ_Att_Fac2
7 5 0 3 // yellow thick3 Typ_Att_Symb
8 3 0 3 // green thick3 Typ_Att_hili
9 9 0 4 // hili thick4 Typ_Att_hili1
10 10 0 1 // dim thick4 Typ_Att_dim
11 0 0 4 // black thick4 Typ_Att_top
12 2 2 2 // red dashed thick2 Typ_Att_top
# Format: indexNr colour lineTyp lineThick
# colour 0 = black-def. 1 = blue 2 = red
# 3 = green 4 = blue 5 = yellow
# 6 = magenta 7 = cyan 8 = white
# 9 = hili-red 10 = dimmed 11 = faces1
# 12 = faces2 13 = faces3 14 = faces4
# lineTyp: 0 = full-line (VollLinie); 1 = dash-dot (Strich-Punkt),
# 2 = dashed (kurz strichliert) 3 = dashed-long (lang strichliert),
# lineThick: 1-6, thickness in pixels

<h2>menu Standards -> Directories</h2>
All directories that should be accessed with File / Open Model,
must be defined here. This sets the symbolic directory list in the button
"DIR-SYM" in the menu File -> Open model dialog.
There must be a directory set for each symbolic name defined on the list defined.
These can be set to any directory. These can be set with a text editor by
editing file {base}/xa/dir.lst. Note: Access rights for writing is required.
Unix example:
Data /usr/home/gCAD3D/dat/
IGS /mnt/win_d/gCAD3D/Models/igs/
MS Windows example:
Data C:\WINDOWS\gCAD3D\dat\
IGS F:\MODELS\gCAD3D\igs\
CD0 D:\
The symbolic directory '.' is replaced by the currently active directory
(Eg. for textures to load from the same directory as the native model).

<p><a name="Start"></a></p>
<h2>Startup / Startup Parameters:</h2>
<b>Startup:</b>
The model {base}/tmp/Model will automatically be opened on startup.
Submodels are given the filename {base}/tmp/Model_{submodelName}.
You can create these files with any preprocessing program.
The file {base}/tmp/Model is automatically created when the program ends.
<b>Startup Parameters:</b>
The program can be started with the following parameters:
new // open blank model.
load // load named model. Path/filename is the following parameter.
defLoad // load the default model (normally done automatically)
// after processing startup parameters.
reLoad // reload the temporary model (after crash)
run // work from defLoad Model (before exit)
comp // compile dll's - activate checkbox
exit // normaler Programmstop (mit sichern)
mode_cad // start in CAD mode.
mode_man // start in MANual mode.
noTB // no Toolbar
noMB // no MessageWindow
Undefined parameters:
{Filename}.{Filetype}
Filetype .gcad, .dxf, .igs, .stp, .bmp, .jpg:
// load model (image). File name must be complete.
No filetype: // plugin (DLL, shared library) with that name to load;
<i>Examples:</i>
./gCAD3D new
Start with no model loaded.
./gCAD3D load sample_interact1.gcad noTB noMB
Load model "Sample_interact1" from the last directory used (DirIn),
hide toolbar and message window.
./gCAD3D comp defLoad tst3
Dynamically download and compile dll (shared library) TST3,
and startup with default model.

<h2>Program Directories:</h2>
Standard File Locations:
All directories are created under ${HOME}/gCAD3D/
The program directories in the startup script gCAD3D.sh can be altered if required.
