Examples
This page lists several examples for this command.
Prompt the user for the filename
This example will prompt the user for the files by opening a dialog box for selection.
File_Open /File_Name= ;

File_Open= /File_Name= c:\demo_files\walking.c3d ;
Specify the filename using wildcards
This example specifies the filename by using a wildcard. All C3D files in the c:\demo_files folder will be opened.
File_Open= /File_Name= c:\demo_files\*.c3d ;
Specify the filename using a pipeline parameter and wildcards
This example uses Pipeline Parameters to specify the folder containing the data files and uses a wildcard in the filename
Set_Pipeline_Parameter_To_Folder_Path /PARAMETER_NAME= DATA_FOLDER /PARAMETER_VALUE=c:\demo_files ; ! Now open the file. File_Open= /File_Name= ::DATA_FOLDER&*.c3d ;
Specify the filename using the default data folder and wildcards
This example uses Pipeline Parameters to specify the default data folder containing the data files and uses a wildcard in the filename.
Set_Pipeline_Parameter_To_Folder_Path /PARAMETER_NAME= DATA_FOLDER /PARAMETER_VALUE=VISUAL3D_DEFAULT_DATA_FOLDER ; ! Now open the file. File_Open= /File_Name= ::DATA_FOLDER&*.c3d ;
