With InverseKinematics, your motiondesign (that you design with MotionDesigner) is defined for a Tool/EndEffector. Then, typically, you add more parts, which you join to the ToolPart, to create a more complex kinematicchain. Finally, you use a servomotor to drive a part that in the kinematicchain, that has a different motion to the ToolPart. To plot the motion for the servomotor you can use a Measurement FB, add a Graph FB, and then export a list of positional datapoints for the servocontroller. While this is often satisfactory, it is often preferable to give the servocontroller a series of polynomials rather than a list of datapoints. The output from the Polynomial Fit FB is the bestfit motion to the data at its inputconnector, but defined as a series of 5th order Polynomials. You can export the Polynomials directly to MotionDesigner. In MotionDesigner, you can further manipulate the Polynomials, as required. 
What to do :

STEP 1:Add a PolynomialFit FB to the graphicarea
The PolynomialFit FB is now in the graphicarea 

STEP 2:Connect a wire to its inputconnector.
A wire is now connected to the inputconnector of the PolynomialFit FB. 

STEP 3.Open the PolynomialFit dialog:
The PolynomialFit dialog is now open. STEP 4:See Polynomial Fit dialog Notes:
