I have run program of create sketch of square using C# . Program runs without error but it is not creating any sketch in solidworks. unable to trace problem.

//--------------------------------------------------------------------------

// Preconditions:

// 1. Open SolidWorks.

// 2. Verify the location of the part template.

//

// Postconditions:

// 1. Click the green check mark in the Modify dimension dialog

//   (look for the hidden dialog behind your other windows).

// 2. 3DSketch1 is in edit mode and contains a spline and a corner rectangle.

// 3. The display dimension of 63.238 mm appears on the y axis starting at

//    (-0.1, 0, 0.01111142101618) while the sketch is in edit mode.
