Autodesk Developer Blog : Creating a linetype using ARX

To create a new linetype you need to create an instance of AcDbLinetypeTableRecord class and add it to the linetype table of the drawing.

The sample code below shows how to do this:

// Creates a new linetype and adds in to the linetype table

//———————————————————–

static void createLinetype()

{

AcDbLinetypeTable *pLtypeTable = NULL ;

// Get the linetype table from the drawing

if( acdbHostApplicationServices()->workingDatabase()->

getLinetypeTable(pLtypeTable, AcDb::kForWrite) ==Acad::eOk )

{

AcDbLinetypeTableRecord *pLtypeTableRecord =

new AcDbLinetypeTableRecord;

// Set all of the properties of the linetype table record

pLtypeTableRecord->setAsciiDescription(_T("T E S T -"));

pLtypeTableRecord->setPatternLength(0.75);

pLtypeTableRecord->setNumDashes(2);

pLtypeTableRecord->setDashLengthAt(0, 0.5);

pLtypeTableRecord->setDashLengthAt(1,-0.25);

pLtypeTableRecord->setName(_T("T_E_S_T"));

AcDbObjectId tmpId;

// Add the new linetype to the linetype table

if(pLtypeTable->add(tmpId, pLtypeTableRecord)==Acad::eOk)

{

pLtypeTableRecord->close();

acutPrintf(_T("\nNew linetype successfully created."));

}

else

{

delete pLtypeTableRecord;

acutPrintf(_T(&
quot;\nCannot add new linetype to the drawing."));

}

pLtypeTable->close();

}

} // end of createLinetype()
