Q - question

The entity isn't planar to the World Coordinate System and can't be converted.

A - answer This error messgage may appear e.g. in the case when you attempt to convert an "Arc" entity to a Feature Line in AutoCAD Civil 3D. It may be be caused by wrong export of DWG geometry from the Microstation software (the DGN source).

In the arc properties, you can see the line "Normal Z" with the value of -1.00000 instead of the standard 1.00000. You can fix the whole drawing e.g. with the LISP utility Normalize (see Helpdesk > Documents > General), or using the free utility Reset210 (see, or with the FLATTEN command (it may change also other values inadverently).

If all this fails, replace the complaining entity with segmented 3D polyline using the Curve2Lin utility.
