******Updated: Attached now, @dan thanks for the file fix. I am working on trying to figure out how to write an equation, with references to cells, in a spread sheet. Then have the equation transfer to the VBA coded. Ideas welcome! ****
So I put something together for this bowl. It is an Excel spreadsheet that can make a graph, based on an equation, and then offset it. The first sheet is where you can add variables as you see fit. The second sheet, named sheet5, is where the graph appears. The graph can be saved as a PDF, then imported into Inkscape, where it can be manipulated as you see fit.
The equation in this is the heart equation from above. Feel free to modify it as you want. I cannot figure out how to make it easy to change the equation from the cells. So you have to go into the developer tab, and open up the macro, and change it there.
Oh, allow or enable macros for this to work. I am sure this would of been better with Open Office, but I know Excel better, and I think Open Office uses Python. I do not know Python, I barely know VBA.
On the first page:
Base radius is the size of the first iteration. I set this bigger for other equations, 0 is fine for this one
Distance is the space between each iteration
Loops is how many times it goes out
Counter is how much the equation counts up to. I have it set to count in 0.1, this can be upped
I apologize for the shoddy code, I build boxes, not programs. So a first time making something like this, and this complex. Stack overflow, Google, and blogs were my friend on this one.
Enjoy! I hope someone finds this useful. I plan to use this for my bowls.
