I like make design with curves, my first idea was to build something like a plane wing or a a boat hull.
Finally, i choose an Egg.
Let's start with Sketchup, I realize that drawing an egg it's not so easy.
I found a tutorial showing that's easy to draw it with with 4 circles. Look at the shoes ! My egg should be from an ostrich...
So, I need some volume now, I use the "follow me" tool to do it.
We have now a 3D egg, I colorize just for fun, ang begin to slice the object.
I export the cross section in 2D and paste the "tiff" in Inkscape.
I made a little animation, basic...
Ok, let's back to work...
With Inkscape, I choose the middle cross section, copy paste and resized at 65%, then aligned and drew the notches.
After a few tests, I cut notches at 2.85 mm, the MDF I used is 2.96 thick the assembly is very good.
I just have to muscling in and it is strong.
Not finished for now, I had issues with clones, I spent time without understanding that clones can't be mixed with normal objects,
finally I found the "unlink clone" function.
Back to the Lab this monday, I explain to Lorenzo my difficulties with Inkscape, my deception about my work this week.
This is the issue I had during this week : when I copy an object, Inkscape paste an image (bitmap) instead of vectoriel !!!
We look for this on the web, a few minutes later, we find many complaints about this behaviour, Inkscape bugs on OSX !
DAMNED ! I found some tips here: https://bugs.launchpad.net/inkscape/+bug/307005
I lost many hours and I felt a complete moron.
Finaly, I drew a parametric design using "clones": "Clones" manage teh thicness off notches.
So, let's go to the Trotec Speedy 400. I Used 3MM MDF and customize a set up. I found that the Trotec default was too "Burny".
