What is RemoteControl

With RemoteControl you can control the cad-program gCAD3D from programs.
All programming languages can be used, even shell-scripts.
For input and output 2 pipes (Linux; MS-Windows: Files) are used.
Input and output is done with textcodes, not binary.

Linux:
  The inputpipe is ${HOME}/gCAD3D/tmp/CTRLpin;
  the outputpipe is ${HOME}/gCAD3D/tmp/CTRLpout.
MS_Windows:
  Input from %APPDATA%\gCAD3D\tmp\CTRLpin
  Output to %APPDATA%\gCAD3D\tmp\CTRLpout


You can send commands from a terminalprogram (Linux: xterm oder gnome-terminal; MS-Windows: cmd)
  to gcad (example: clear active model):
Linux:
  echo 'new' > ~/gCAD3D/tmp/CTRLpin
MS_Windows:
  echo new>"%APPDATA%\gCAD3D\tmp\CTRLpin"


Send a commandfile to remoteControl:
 - put the following 6 lines into  file t1.dat:
new
add(P1=P(100 0 0))
add(C1=P1 50)
#eof

Send the file:
Linux:
  cat t1.dat > ~/gCAD3D/tmp/CTRLpin
MS_Windows:
  copy t1.dat "%APPDATA%\gCAD3D\tmp\CTRLpin"


Receiving output from gcad (eg display the output in a terminal-window):
Linux (keeps connection):
  cat  ~/gCAD3D/tmp/CTRLpout
MS_Windows (new file after each remote-command):
  type %APPDATA%\gCAD3D\tmp\CTRLpout

Gcad sends after each command at least a new-line-character (ascii 10).


<b>Programming Examples:</b>
VB.Net (MS-Windows): <A HREF="../../prg/Demo1gCadRemoteControl.zip">Demo1gCadRemoteControl.zip</A>
Java: <A HREF="../../prg/DemoRC1.java">DemoRC1.java</A>

All following examples are linux-examples.

Please send improved examples or examples for other programming-languages to
 support at gcad3d.org


__________________________________________________________________________
<p><a name="PRI"></a></p>
PRINT(text)          // print text (into messagewindow)

Objects (points, vectors, variables) are decoded.

Example:
echo 'print("TestPrint 1")' > ~/gCAD3D/tmp/CTRLpin
# display coordinates of point p1 and vector D1 with:
echo 'print("P1 = ",P1," D1 = ",D1)' > ~/gCAD3D/tmp/CTRLpin


__________________________________________________________________________
<p><a name="GLN"></a></p>
<p><a name="DFO"></a></p>
GETLNR               // get current lineNr
DELFOLL(lnr)         // delete all lines following lineNr

# lineNr from GETLNR can eg later be used for DELFOLL
#   (delete all objects created after getting 'GETLNR')


__________________________________________________________________________
<p><a name="GOI"></a></p>
GETOBJINDNXT(typ)     // get next free object-index for points


# example: get next free DB-index for type point:
echo 'GETOBJINDNXT(P)' > ~/gCAD3D/tmp/CTRLpin
# See list of <a href="CAD_Base_en.htm#Codeletters">objecttypes</a>


__________________________________________________________________________


__________________________________________________________________________
<p><a name="ADD"></a></p>
ADD(code)            // process and store source-objects

# code is any valid gcad-text; see <a href="CAD_Base_en.htm#Codes">Codes</a>
# eg create a point with:
echo 'add(P1=P(100 0 20))' > ~/gCAD3D/tmp/CTRLpin

__________________________________________________________________________
<p><a name="ADF"></a></p>
ADDFILE(filNam)      // process and store cad-objects in file

echo 'addfile("t1")' > ~/gCAD3D/tmp/CTRLpin

Example for file t1:
MODE(MEN,off)
MODE(BRW,off)
MODE(BAR1,off)
MODE(BAR2,off)
new
add(P1=P(100 0 0))
add(C1=P1 50)
zoomall
#eof


__________________________________________________________________________
<p><a name="MOD"></a></p>
MOD(code)            // modify cad-code, update


Example:
echo 'MOD(V1=70)' > ~/gCAD3D/tmp/CTRLpin

# modifies the line "V1=50" in the existing code:
# and updates the variable V1 and the circle C1.

P1=P(100 100 0)
V1=50
C1=P1 V1


__________________________________________________________________________
<p><a name="SYM"></a></p>
GETSYMDIR(sym)       // returns path for symbolic-directory <sym>
SETSYMDIR(sym,path)  // set new symbolic-directory
DELSYMDIR(sym)       // delete symbolic-directory <sym>


# get absolute path for (existing) symbol "Data"
echo 'GETSYMDIR("Data")' > ~/gCAD3D/tmp/CTRLpin

# set new symbol "myPath" to path "/tmp/gcad/"
echo 'SETSYMDIR("myPath","/tmp/gcad/")' > ~/gCAD3D/tmp/CTRLpin

# delete symbol "myPath"
echo 'DELSYMDIR("myPath")' > ~/gCAD3D/tmp/CTRLpin

# clear error
echo 'ERRCLR' > ~/gCAD3D/tmp/CTRLpin


__________________________________________________________________________
<p><a name="LOA"></a></p>
LOAD(modelname)      // clear and load new model (native, step, iges, dxf ..)


Load models; filename can be symbolic, relativ or absolut.
# Example symbolic-filename:
echo 'load("Data/sample_area1.gcad")' > ~/gCAD3D/tmp/CTRLpin
# Example relative-filename (using current symbolic directory):
echo 'load("../dat/sample_area2.gcad")' > ~/gCAD3D/tmp/CTRLpin
# Example absolute-filename:
echo 'load("/tmp/test1.gcad")' > ~/gCAD3D/tmp/CTRLpin


echo 'MODSIZ(10000)' > ~/gCAD3D/tmp/CTRLpin
echo 'END' > ~/gCAD3D/tmp/CTRLpin


<p><a name="LSM"></a></p>
LOADSM(submodel)     // load submodel (can only load native models (.gcad))

# submodels need to be in a symbolic directory. See SETSYMDIR.
# Example load submodels, use submodels:

echo 'loadsm("Data/sample_mod_blech1.gcad")' > ~/gCAD3D/tmp/CTRLpin
echo 'loadsm("Data/sample_mod_screw1.gcad")' > ~/gCAD3D/tmp/CTRLpin
