AutoCAD API .net. Matrix3d accuracy

james — Mon, 19 Jun 2017 14:04:41 GMT

Hi All,

i am writing an application in .net and i am trying to get a more precise transformation matrix.

currently, the only way to get values into the matrix is using the datatype double, this datatype is limited in the number of characters, i would like to build my transformation matrix based on decimal datatype.

is this possible?

i am doing something like this currently

if (cells.Length == 16)
            {
                for (int i = 0; i < cells.Length; i++)
                {
                    data[i] = double.Parse(cells[i]);
                }
            }
            return new Matrix3d(data);

and i want to use decimal or just transform my data more accuratly.

any ideas?

Matrix3d stores the matrix data as type System.Double.

The only way to be more precise, is to write your own Matrix3d class that stores information in whatever type you prefer.
