MI-L MapX5 - invalid distance type for coordinate conversion in buffer operation

[Faragó Attila]

Hi,

Any ideas?

I use Delphi 6 & MapX 5.0.25.
No I set the numeric coordsys to non-earth, meters.

  r := CoRectangle.Create;
  r.Set_(0,0,1000000,1000000);
  mapMain.NumericCoordSys.Set_(0,miUnitMeter,miUnitMeter,
    EmptyParam,EmptyParam,EmptyParam,EmptyParam,EmptyParam,EmptyParam,
    EmptyParam,EmptyParam,EmptyParam,
    r,EmptyParam);
  r:=nil;

then make a line,

    pts.RemoveAll;
    pts.AddXY(x1,y1);
    pts.AddXY(x2,y2);
    cmxl := mapMain.FeatureFactory.CreateLine(pts,EmptyParam);

then try to make a buffer around this line:

    cmxb := mapMain.FeatureFactory.BufferFeatures(
      cmxl,
      10,
      miUnitMeter,
      EmptyParam);

Then I get an exception:
 "Invalid distance type for coordinate conversion in buffer operation"

So, any ideas?
:)
