Hi Michael,

OK, I understand with those current method.

Please open attached video to understand what I want to do in Moi.
Thanks for your quick support !

Hi Michael,

Looks like I have use this method :

Hi Anis, here is what I would recommend for doing this in MoI.

First create the 60x60 radius 15 rectangle by the following method:

Start the Draw curve / Rect / Center command.

Click on the "Rounded corners" option so it is turned on (has a check mark on it).

Type 0 <enter> or click the origin point for the first point.

Type 60 <tab> 60 <enter> to set width and height to 60 and 60.

Type 15 <enter> to set radius 15.


You now have the basic shape, but you want one that has a different point structure, so you can now use that basic shape as a tracing guide while you draw a new curve.

Start the Draw curve / Freeform / Control points command.

Turn on grid snap, and click points at the endpoint and midpoint of each line segment, and in the corner of the rectangle, that is 17 points in total.

Now you will have a curve that has the control point structure that you want, same as the control point arrangement in the video, and you should be able to select the points and move them as in the video.

This shape will not have a perfect arc in it, the control point curve will be a slightly different shape in the corner areas, if you want you can select those 4 corner points and scale them in somewhat to make the shape closer.

In the next beta release it will be possible to edit the 3 point arc the way you wanted so the exact arc (which stretches out in this case to become an ellipse actually, but an arc as viewed from above) will work better in that version.

But the method that I describe above should get you a close shape to that.

Please let me know if you need any illustrations or additional information for any step.

Hi Anis,

> Looks like I have use this method :


That way looks fine too - then you can use Transform / Array / Circular to copy that piece to the other spots.

Michael....

We are looking forward for never ending improvement for the next release of moi !!!
Thanks for your support !

Hi Anis,

> Looks like I have use this method :

Instead of using a curve to join the corner rads use >Construct>Blend, in that way you know all your curves are tangent, and you also have Bulge control to get different results and still maintain tangency.

Cheers

Hi Danny,

when I use blend the result will be same if I use fillet. Look at the control point....
About nudge, I tried those script.
When I click my page up or page down keyboard, the result is rotate object.
Is that correct ?
I read on the petrs moi web page about use this script to move point.
How we can do that ?

Look at attachments below........

Hi Anis,

>>About nudge, I tried those script.

Did you download the file Nudge.zip or NudgeViewAxis.zip?

Could you check a keyboard shortcuts?
If you download and unzip the file Nudge.zip into the \commands subfolder under your MoI main program files folder, the items in the shortcut keys section should look like:

PageUp		Nudge zup
PageDown	Nudge zdown

You seem to have a script to rotate view there instead(?)

PageUp         script:moi.ui.mainWindow.viewpanel.getViewport('3D').rotate( 'up', 6.0 );

>>when I use blend the result will be same if I use fillet

Actually, those shapes are slightly different. The control point structure look similar for both fillet and blend in MoI; but if you would copy the curves to Rhino and turn control points on, you could see the difference.




Like Michael mentioned above:


By the way, why do you exactly need that structure of control points?

Uppsss...not yet set up this.... Now working fine.

>You seem to have a script to rotate view there instead(?)

yes, correct.

I see now

>By the way, why do you exactly need that structure of control points?
I just follow a tutorial from Rhino3DTV on how to create a bottle. Check my previous post on this thread. I want to know how we can create the bottle in Moi3D.

Thanks for your tips... :)

One other difference between Fillet and Blend, is that Fillet is done on 2 curves that are on one common plane with each other, while Blend works off the end of any 2 curves, they can be swooping around in 3d or whatever they don't have to be coplanar for blend.

Hi Petr,

>>The control point structure look similar for both fillet and blend in MoI; but if you would copy the curves to Rhino and turn control points on, you could see the difference.

Are you not looking at a default fillet from MoI (Circular) compared to a default blend(G1).

Fillets in MoI can also be made to G1/G2/G3 so a need to compare similar settings (with fillet/blend) on such a planer construction.

Hi Steve, I think the fillet with option G1/G2/G3 is not further fillet ;) From my point of view, it is just kind of smart blending for solid/polysurfaces. By the way, circular option also keeps a tangent (G1). -Petr

Hi All....

Finally, below are the result :)
