Create this shape in MoI

Hi,

I am trying to create this round shape in MoI. It must be something easy that I miss. I tried offset but then I don't get the nice rounded edges between the circles. Any idea how to achieve it?

This is what I want to do:


And this is what I have now:




Thanks,
Stefan

Hi Stefan, you were going in the right direction - you do need to use Offset or just draw a larger circle so you have started the thickness. Then you can use the Draw curve > Arc > Tangent command to put in the rounded edges between the circles.

The arc tangent command lets you make an arc tangent between existing curves, you'll place the first point on one circle somewhere generally nearby where you want your final piece to start, and the second point on the other circle generally nearby where you want it to end, and then for the third point that can either go snapped on to another curve to make an arc tangent to 3 curves or through a point to make an arc tangent to those 2 first curves and through the given point. That defines a circle and then the last step is to pick which piece of that circle you want to keep.

It looks like this:



Once you have created one piece you how like it, use Transform > Array > Circular with an item count of 3 to replicate it, then select your outer circles and use Edit > Trim to cut them with the arcs.

Hope this helps!

- Michael

Alright got it. It is a bit wonky but it works. I had to create additional circles and then trim the outer part. Then I got a slim shell which I can use to expand.

Hi Nicolinux,

As long as I can, I don't usually use offset because it adds unwanted control points and complexity to the resulting curves/surfaces.

Here's a little tut. Obviously there are many ways to do it, and this is one of them.
N.B. I used 2 circle with a radius of 15 and 19 and I did a final chamfer of 2, that is (19-15 = 2).

Wow, thank you. I feel so humbled, but happy :)
Marco, what is this advanced sorcery you are using to display an inline menu with all MoI commands? It looks really handy.

Hi Marco, offset of a circle or circular arc is handled as a special case and will generate another exact circle or circular arc, so you shouldn't need to worry about increased control point density for those.

Hi

It's my very personal Moi's config.

If you are interested in, look at this brief video : http://take.ms/x7cOY (thread : http://moi3d.com/forum/index.php?webtag=MOI&msg=8122.1)

And also at this thread : http://moi3d.com/forum/index.php?webtag=MOI&msg=8123.1

I'm sorry for the HUGE mistake in my previous post!! (http://moi3d.com/forum/index.php?webtag=MOI&msg=8128.5)

(19-15 = 2) LOL LOL LOL

A brand new Mathematics....

I wanted to say : 19-15 = 4, that is the chamfer (2) * 2

Hi Nicolinux,

Here's a quick and dirt render and turntable done in 3D-Coat :

Oh man, now I am really jealous. How do you create such pretty renderings?

Btw. I created this model for one specific purpose - to print it and have a miniature spinner :)

Why do you share such image in PNG format ?
It's 50 megas! I have a very slow connection at this date so...
Same in JPG (compression 75%) is 750 kb even in big format 5760 * 3018

Hi

> Oh man, now I am really jealous. How do you create such pretty renderings?

I exported the model from Moi to obj format with maximum detail level, then imported in 3D-Coat for Pixel Painting.
In 3D-Coat I've simply applied some simple Smart Materials and finally I rendered directly inside 3D-Coat.
Thtat's all!

Best,

Hi Pilou,

> Why do you share such image in PNG format ?

I made a mistake.

I thought I'd converted to jpg before uploading.

This is the jpg image http://take.ms/MVbWb

P.S. Anyway, the original PNG that I uploaded is 4.5Mb on my HD, not 50 Mb as told by you. I don't know where these 50M come from...

Best,
