Arc/Curve Data
« on: August 25, 2015, 10:25:07 PM »
Do arcs have tangent / delta properties or do they need to be calc'd out? If so anyone have an example?

Arc.TotalAngle perhaps ...

Code - C#: [Select]
  1.  
  2.   // Properties
  3.   public Point3d Center { [Category("Geometry")] get; set; }
  4.   [UnitType(UnitType.AngleNotTransformed)]
  5.   public double EndAngle { [Category("Geometry")] get; set; }
  6.   [UnitType(UnitType.Distance)]
  7.   public double Length { [Category("Geometry")] get; }
  8.   public Vector3d Normal { [Category("Geometry")] get; set; }
  9.   [UnitType(UnitType.Distance)]
  10.   public double Radius { [Category("Geometry")] get; set; }
  11.   [UnitType(UnitType.AngleNotTransformed)]
  12.   public double StartAngle { [Category("Geometry")] get; set; }
  13.   [UnitType(UnitType.Distance)]
  14.   public double Thickness { [Category("General")] get; set; }
  15.   [UnitType(UnitType.AngleNotTransformed)]
  16.   public double TotalAngle { [Category("Geometry")] get; }
  17.  
  18.

Looks like that will work for the delta. Thank you!

I'm sure it will.

and Tangent would be rad * tan (delta*0.5) I bet.

added:
Though I s'pose it depends on your usage of the word Tangent.
I assumed:
