MaxED and rotating angles

[Kozak]

Ok I wanted to make some kind of hospital light, a big bulby one. Like in half a sphere. I did the routine, I modeled a cilinder and a pie piece and did intersect, which gave me a nice piecie to rotate and make half sphere of.

The piece:
| 1 lenght unit
|
---------------
4 lenght |
units |

I did a bit of calculating on the angle:

2*tan(0.5/4)^-1=14.25, so the piece has that angle. I adjusted ME for using that angle. And the pieces all rotated nicely. Though at the end they overlapped so my whole light was kinda crappy :'(. Because I didn't really gave thought to which angle to use.
But the strange part is that my almost complete half sphere consist of 12 pieces, which should give it an angle of 12*14.25=168.36, while a whole circle is 360 degrees. What is happening?

[Aknott]

Why tan calculation?
The pie piece angle must be a division of 360 (360/12=30), because the boolean result will be duplicated and rotated so to complete the sphere.

Edit: once the sphere is completed, cut it /and scale it if there's a need to.

[Noodlez]

so if you want a slightly more detailed sphere you do 15 or 7.5?

[Kozak]

Ok, but if you have that angle how do you know how deep and how long the piece should be?

[Aknott]

Yes.
Well, 7.5° means 48 sphere parts which can be a lot.

I know, making sphere (or even half) are pain in the ass when you're trying to find out right angle.

If you don't want to trouble yourself use Aknott's primitives prefab pack.

[Jokke_r]

i allways use 15°angles...

[Noodlez]

If you don't want to trouble yourself use Aknott's primitives prefab pack.

ive been using it for aaaages now, Aknott is Da Man!
but i would like to learn for myself, just to add to the information build-up of MaxED2 in my brain

[Aknott]

The dimensions for the cylinder and the pie piece should be whole numbers. You will be able to scale the resulting sphere properly.
If you cut it at somewhat height, you'll surely lost this precision.
But you should worry about that, who cares if it does not have perfect dimensions. It just needs to have good proportions and scale for the eye.

[Kozak]

Alright thanks, I now learned the technique how to make that angled stuff. It really comes in quite handy.

[Joonas]

Aknott, write a conclusion of all this?

[Ghast]

Does anyone still have Aknott's primitives prefab pack that they could share?

I remember it as a level similar to his stairs, scaffold & kitchens prefabs BUT am unable to find it on any of the surviving contains-all mega prefab packages.

Needless to say it is slow work starting from scratch lol

Got it from Hitman woot
