Offset polyline INTERNAL ERROR

Sometimes when you offset a polyline AutoCAD crashes


If you attempt to offset an old-style heavy polyline that contains arc segments and the plane of the polyline is not parallel to the current viewing plane, AutoCAD may crash with the message INTERNAL ERROR: !offset.cpp@312: eInvalidInput.

Workaround: Use lightweight polylines. Alternatively, make sure you view the drawing from a plan view with respect to the polyline before you offset it.
