Place the input .igs file in the "file" folder before running this command. Radius Dimension Parameters NOTE: When changing radius values, also modify the arc end points. For example, with a right angle fillet and the following parameters: r1=.125 x1=.500 ! Location of arc end tangent to horizontal line y1=.375 z1=.000 x2=1.500 ! Location of arc end tangent to vertical line y2=2.000 z2=.000 Change the parameters to: r1=.150 ! Any Desired value x1=.500-(r1-.125) ! The first "-" may need to be "+" paramter of r1 = .125, suppose it is desired to set set r1 = .150.
