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). If you want to activate the program from "Remote/ Select-Start": Put start-scripts into directory /remote Put executables into directory Programming Examples: VB.Net (MS-Windows): Demo1gCadRemoteControl.zip Java: DemoRC1.java All following examples are linux-examples. Please send improved examples or examples for other programming-languages to support at gcad3d.org __________________________________________________________________________

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 __________________________________________________________________________

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') __________________________________________________________________________

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 objecttypes __________________________________________________________________________ __________________________________________________________________________

ADD(code) // process and store source-objects # code is any valid gcad-text; see Codes # eg create a point with: echo 'add(P1=P(100 0 20))' > ~/gCAD3D/tmp/CTRLpin __________________________________________________________________________

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 __________________________________________________________________________

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 __________________________________________________________________________

GETSYMDIR(sym) // returns path for symbolic-directory SETSYMDIR(sym,path) // set new symbolic-directory DELSYMDIR(sym) // delete symbolic-directory # 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 __________________________________________________________________________

LOAD(modelname) // clear and load new model (native, step, iges, dxf ..)
