Value of the angle

[robsonjmartins]

How can I get the angle of a line as shown in the picture?

if (obj.GetType() == typeof(Line))
        {
             Line linha = (Line)obj;
              double angulo = linha.Angle;
              Point3d startPoint = linha.StartPoint;
              Point3d endPoint = linha.EndPoint;
         }

For in my code I techo angle value in double.
Could I have a method return the integer value of the angle?

You already have the angle as a double. Have you tried converting the double to an integer? Unless I am misunderstanding what you want, this is really a very basic beginner programming question.

Yes!

int angInt = (int) angulo;

To be completely clear my doubt, I have a " Block Reference " where I walk every entity in search of line with the desired angle.  When I have a line that has 0 degree and 180 degree method returns me to the ralor 1.5707963267948966 and when I have a line that has 90 degrees and 270 degrees the method returns me 0.0.

You can not convert from Radians to Degree?

There was a mistake on my part that the values ​​mentioned above was because I was taking only the first entity in each block.
And from what I could see this returned value in decimal, the value would be in radians, or simply convert the radian ( radian eg - > degree = 1.5707963267948966 - > 89.99999999987068956723, rounded, 90).

Thanks to the help of friends.

Robson, seu interesse com cotas seria para gerar memorial descritivo?

[robsonjmartins]

Não amigo,

Estou em um projeto onde o objetivo é pegar as cotas que na verdade são blocos exportados de um desenho feito no programa Tekla Structures e transforma-las em cotas reais do AutoCAD.
