Shape files do not support arcs

[AradGazit]

Hi,
A very serious limitation to the use of shape files is their inability to support arc and circle geometry. This causes any CAD data containing arc and/or circles to be turned into small straight segments that do not reflect the true geometry, are not accurate and make the files much bigger then needed.
When importing data from shape files all arc or circle data (Originally) is imported as straight lines.
