How can I determine if an arc is clockwise in direction?

Hi,

If you're talking about the Autodesk.AutoCAD.DatabaseServices.Arc type (IOW Arc entity) it's always counterclockwise according to is Normal.

If you are talking about a Polyline arc segment, you have to check the Bulge sign (negative = clockwise).

Only the Autodesk.AutoCAD.Geometry.CircularArc2d type have a IsClockWise property.

Thank you giles. I was talking about a regular arc. That's interesting it's always counterclockwise. Made what I was doing easy :)  Much appreciated.
