I am about to get on my math soapbox. I have an issue with Quilt Path's use of the word "Parabola" to describe the shape it is letting us draw. By definition a parabola is symmetrical. What Quilt Path is letting us draw is asymmetrical. It is actually a Non-Parabolic Arc. This is just proof to my High School Trigonometry teacher that I was paying attention. I think she knew that anyway, since it was one of my favorite classes.
Now that I have gotten that off my chest, we are going to continue our discussion of the Pattern | Draw and Pattern | Edit features in PatternCAD. The two items we will be looking at today are Arc (which for the record lets us draw a Parabola) and Parabola (which allows us to draw a Non-Parabolic Arc). I know, I really do need to get over it!
In the screen shot above I actually let go of the blue squares in about the same position on both the Arc and the Parabola. Notice that the Parabola distorted into an Asymmetrical Arc. That really is the difference in the two options.
