Making Square to Round fabrication easier
Hello fellow designers. I've got another square to round shape like the attached image on my next satellite build and I'm hoping someone has an easier method of fabrication.
Of course I could build the part in Blender and allow the 3d shape to be flattened. Or by using an old drafting method like the following link https://sheetmetalworld.com/sheet-me...quare-to-round But both of those are a bit time consuming, so I'm wishfully thinking that there might be a web calculator that can layout the shape like some of the truncated cone calculators I know and love so much. Any suggestions?

Terrible is it not that designing is so time consuming.
Gurgle search with the phrase "square to round calculator" and within 10 minutes max I had installed exactly what you're looking for. I think it works but I'm too busy with the time consuming task of present wrapping to check. Happy Holiday one and all. |

Maurice,
You could, in the spirit of the season, have posted the link to the calculator you found and downloaded. Rick

Its okay Rick, viglink was nice enough to highlight the word "calculator" for us, making me think that a link ... but ... ahh well.

Nowt to do with the season. Normally I do post links but somehow I simply missed this time.

I'm almost afraid to think what the link you got was...

try this link:
Online plaatuitslagen maken it's in dutch, and it only shows a preview, but maybe you can use the print screen option? |

Aye, Aye, Cap'n.
Trouble is it's time consuming. Anyway the original question as asked has been answered twice already. Don't use Blender meself but would have thought making the shape in Blender, saving it in 3DS format and unfolding it in Pepakura - perhaps at the exorbitant cost of $39 - would be a way to go for this and other segments of a design. |

First up Pepa is now only $38. More importantly the three 3D programs I've tried all got confused when asked to develop this shape. The curved bits are each part of the surface of an oblique cone with circular base. Those parts lie on the surface of the cone between a quarter of a circle at the base and a single point further up the cone. That single point is the problem and is just too much for the programmes. They insist on generating curved instead of straight lines between the end points of the arcs and the single point. So the accurate way of plotting the shape is by using the manual technique. This seems to be the what's happening with the two links previously posted. Of course doing it in 2D Cad on a computer is significantly easier, and very much quicker given the ability to mirror copy rather than repeated drawing with paper and pencil. Now I'm off to do something useful. |
