Draw a Chlotoid in Microstation 1

[costicap]

I'm working with Microstation v7J and I'm looking for a step by step procedure to draw a chlotoid. I tried to do it but I didn't understand the following terms: initial degree, final degree.
Thanks for helping me!

Initial Degree: Sets the degree of curvature at the origin.
Final Degree: Sets the degree of curvature at the spiral's endpoint.
Also if you are using MicroStation V7 if you go to the help drop down menu and click on tracking, MicroStation will follow along with your work and try to offer suggestions, much like a tutorial.
Hope this helps.
