automatically calculate the spacing of points on a curved surface

[Anonymous]

hello, 

Hope you can help me on this one, 

I have a curved shape with slots spaced regularly by 2,7mm on the outer shell of this shape. 

I would like to figure out what is the spacing of every slot on the inside of the shell

As you can immagine, due to the odd shape, every slot has a different spacing on the inside : 

What would be you strategy to automatically measure and ultimately create a flat pattern sketch of the inside shell ? 

Thanks a lot 

Thomas

PS : this topic is for calculating stitch spacing on a leather gusset project.

Hi,

without seeing the design, I can only say that due to the changing radii, even the distances on the inside cannot be constant.
But share the design to look more closely.

sure thing, 

@g-andresen you are right, I should have include the file on my previous post. 

Thanks a lot for your help,

Quick question:

You do realize that your spline is not symmetric across the Z -Axis and that offsetting a spine breaks the curvature?

Hi, @TrippyLighting, 
Yes I did...And i couldn't figure out how to fix it 🤔

I mirrored the spline handles, but still...

@TrippyLighting OK I managed to repair the sketch

please find attached the updated file. 

Thanks a lot
