Creating a linetype using ARX


Question
How can I create a linetype using ARX?
Answer
The sample code below creates a linetype using ARX:

1. 
   
2. 
   
3. #include "dbmain.h"         
   
4. #include "dbsymtb.h"
   
5. 
   
6. void utilsarxtest ()     {
   
7.     AcDbLinetypeTable *pLtypeTable =NULL ;
   
8.     // get the linetype table from the drawing
   
9.     if ( acdbHostApplicationServices()->workingDatabase()->getLinetypeTable (pLtypeTable, AcDb::kForWrite) ==
   
10. Acad::eOk ) {
    
11.         AcDbLinetypeTableRecord *pLtypeTableRecord =new
    
12. AcDbLinetypeTableRecord ;
    
13.         // set all of the properties of the linetype table record.
    
14.         pLtypeTableRecord->setAsciiDescription ("T E S T -") ;
    
15.         pLtypeTableRecord->setPatternLength (0.75) ;
    
16.         pLtypeTableRecord->setNumDashes (2) ;
    
17.         pLtypeTableRecord->setDashLengthAt (0, 0.5) ;
    
18.         pLtypeTableRecord->setDashLengthAt (1,-0.25) ;
    
19.         pLtypeTableRecord->setName ("ASTESTER") ;
    
20. 
    
21.         AcDbObjectId tmpId ;
    
22.         // add the pLtypeTableRecord to the linetype table
    
23.         if (pLtypeTable->add (tmpId, pLtypeTableRecord)==Acad::eOk){
    
24.             pLtypeTableRecord->close () ;
    
25.         } else {
    
26.             delete pLtypeTableRecord ;
    
27.         }
    
28.         // close everything up
    
29.         pLtypeTable->close () ;
    
30.     }
    
31. }
