area problem

If these are lightweight polylines, try using the "convertpoly" command to change them to 'heavy' polylines. Then re-check the areas. There is a bug affecting LWpoly's and the area command in AC2000.
542 sqm (m2). approximatively surface beside the (m2) !!???. The points.

OOOOHH!! Extraordinary ! Incredible! We obtain good results with area. Thank you very very much !
Is this bug documented ? Where ?
Sincerely

this is a VERY serious bug in the first release of A2000, (which was fixed in later versions of A2000). It affects LWpolylines which are shaped like a "U" or a horseshoe.In certain cases,if there are no vertexes along the radius of the "U", the area command connects a straight line between the endpoints of the arc in the "U" and doesn't see the radius. There was a patch on the Autodesk website that you could download to fix the problem.
This is a very, very serious bug that almost caused me ( a land surveyor) to miscalculate the area of a piece of land worth millions of dollars. Autodesk , of course, doesn't care about its mistakes, and never bothers to notify the customers of its faulty software..
Everybody makes mistakes, but you would expect a responsible company to issue a "recall" when they make a life-threatening mistake, like the car companies do.( Suppose an aircraft engineer designed a U-shaped bracket to support a heavy weight, and it fails in flight because Autodesk's software engineers don't know how to calculate the area.)
