Can anyone please advise me what the 2D or 3D equation curve for a parabolic spiral, otherwise known as a Fermat's spiral would be?
I have found this info but do not know how to apply it:
Fermat equation
Therefore in terms of the affine plane its equation is
The Fermat curve is non-singular and has genus
I have also found this: $r^{2}=a^{2}\theta $
Please see image attached.
Are you familiar with using Equation Curves in general?
A while back I posted some examples that my students submitted.
I think Autodesk employee has also posted some examples.
At one time there were several that were included in the Samples install, there should be a thread here with those attached.
Do a search and come back with more questions if you can't find the examples to help you work it out.
Thank you, I will search later today.
Equation Curves do appear to a novice like some form of 'black art.' So I am wondering if there is a 'user friendly; App that allows one to configure the equation for any given shape in an Excel Spreadsheet?
Thank you once again.
Thank you Rdyson.
Is there any chance you could assist me with my question on:Variable pitch helical coil with smooth blend please?
Thank you once again.
