MXRoad SS4 Export to AutoCAD Converting to Polylines rather than LTPolyline.
It is down to the version of the installed ACAD RealDWG with SS4. Later versions of the RealDWG drivers create 3D polylines in the DWG and not lightweight polylines. This means that linetypes cannot be applied to these lines in AutoCAD.
Downgrade the RealDWG drivers to fix the export of polylines to lightweight polylines.
The last version which works is: RealDWG 08.11.09.578
• Uninstall the 2014 RealDWG drivers.
• Install the earlier RealDWG drivers
Please let me know if some one assist to get RealDwg2014.msi.
