[ARX函数]：请问ARX如何增加一个acad.lin中的某一个线型到当前图形

请问ARX如何增加一个acad.lin中的某一个线型到当前图形

我也需要问这个问题，欢迎大家回复！

好像ARX中有个专门的函数实现此功能的，在全局函数中：
Acad::ErrorStatus

acdbLoadLineTypeFile(
    const char* ltname,
    const char* fname,

    AcDbDatabase* pDb);

ltname        Input linetype name string (wild cards may be used)
fname        Input path/filename or URL of linetype file to load from (path is optional)
pDb        Input pointer to the database to load the linetype(s) into

This function loads the linetype specified by ltname from the file specified by fname and stores it in the database specified by pDb. If pDb is NULL, then the database currently loaded in the AutoCAD editor is used.
The ltname parameter may contain wild card characters (see acutWcMatch() for more information on wild card usage). If wild cards are used, multiple linetypes may be loaded.
If fname is not a URL and does not contain a path, then the AutoCAD library search path will be searched for the file.

Returns Acad::eOk if successful.
Returns Acad::eNullObjectPointer if ltname or fname is NULL.
Returns Acad::eFileSystemErr If the specified file cannot be opened.
Returns Acad::eUndefinedLineType if the linetype name specified by ltname is not found in the file.
Returns Acad::eBadLineTypeName if the file contains a malformed record, or a syntax error is encountered.
Returns an appropriate Internet-specific Acad::ErrorStatus value if a URL is specified and the transfer is not successful.

看看这个函数吧!希望对你有用阿!
void arxLoadltype(char *ltname)
{

    Acad::ErrorStatus t=acdbCurDwg()->loadLineTypeFile(ltname,"acadiso.lin");
        switch(t)
        {
                case Acad::eOk:
                        acutPrintf("\nLoading linetype OK");
                        break;
                case Acad::eNullObjectPointer:
                        acutPrintf("\nLinetype or Linetype file nanme is NULL.");
                        break;
                case Acad::eFileSystemErr:
                        acutPrintf("\nthe specified file cannot be opened.");
                case Acad::eUndefinedLineType:
                        acutPrintf("\nlinetype name specified by ltname is not found in the file.");
                        break;
                case Acad::eBadLinetypeName:
                        acutPrintf("\nthe file contains a malformed record, or a syntax error is encountered.");
                        break;
                default:
                        acutPrintf("\nLoading Linetype error");
        }
}
