I am designing the acoustic panel. I try to make a solid difference in a stock material which is 400x800x24 mm with a milling
bit which is 19 mm in diameter.
I would like to make a set of ellipses in a top view (see pic 2) and make this pattern 3D as you can see in the pic 1.
I am planning to solve the solid difference by making a reverse correlation between sections A-B1, A-B2, A-B3 etc. and the depth
of the ellipses D1, D2, D3 etc.
The difference in depths of the ellipses is planned to be solved as as the number of offset milling paths.
The brep which I will use to make a solid difference is planned to be solved by Sweep1.
When I started to model my acoustic panel (gh file: E4_03) it turned out that there are a few problems.
- The correlation of ellipses and their depths is opposite to the one that I wanted. The middle ellipses are the most shallow
instead of being the deepest.
- Sweep1 creates a surface only with 1 rail curve. Therefore the ellipses in the middle of the panel cannot be sweeped.
I decided to turn the ellipses into 1 rail curves by the Trim regions component.
That made the internal ellipses able to be sweeped. However it turned out that there are some unwanted breaks between the
sweeped surfaces. > So I decided to make a double set of sweeped ellipses with a 30 degrees rotation.
- Problems with the variations in the number of ellipses
Ex. when I want to have 30 ellipses instead of 20 (gh file: E4_032)
All the operations from pt 1 make my definition very complicated and not very flexible. Therefore in the variation E4_032 the
unwanted break is created (see pic ‘E4_032’)
Does anyone of you know how to rearrange my Grasshopper definition to obtain the form that I was planning?
Or mabye someone knows how to do it in a completely different way?
