There could be several points along the the line within a 100 feet buffer and a tolerance gap of 30 feet between point is required. Assume that there will be no more than 3 points within the buffer.

Extract the angle of the line at this point and move it (create a point) at the required distance and angle.

 

 

Using a affiner you enter

 

dX=@Evaluate(-/+@Value(OFFSET)*@cos((@Value(DirectionalAngle)/180)*$(Pi ())))

 

dY=@Evaluate(-/+@Value(OFFSET)*@sin((@Value(DirectionalAngle)/180)*$(Pi ())))

 

 

so that would be A,B,C = 1,0,dX and D,E,F  = 0,1,dY

 

The -/+ would indicate wich side of the line you'd be moving the point.
