Teigha.TD 设置线型为虚线 - 示例代码

To set the linetype to a dashed line in Teigha.TD, you can use the `setLinetype` method. Here is an example code snippet:\n\nc++\nOdDbLinePtr pLine = OdDbLine::createObject();\npLine->setStartPoint(OdGePoint3d(0, 0, 0));\npLine->setEndPoint(OdGePoint3d(10, 10, 0));\n\nOdDbLinetypeTablePtr pLineTypeTable = pDatabase->getLinetypeTableId().safeOpenObject(OdDb::kForRead);\nOdDbLinetypeTableRecordPtr pLinetypeRecord = pLineTypeTable->getAt(L"Dash").safeOpenObject(OdDb::kForRead);\npLine->setLinetype(pLinetypeRecord->objectId());\n\npModelSpace->appendOdDbEntity(pLine);\n\n\nIn this code snippet, we are creating a new `OdDbLine` object and setting its start and end points. Then, we access the linetype table in the database and retrieve the linetype record for the dashed line (assuming it exists). Finally, we set the linetype of the line to the retrieved linetype record.\n\nMake sure to replace `pDatabase` with the appropriate `OdDbDatabase` object and `pModelSpace` with the appropriate `OdDbBlockTableRecord` object representing the model space.
