Hi Michael
Thank you very much for the replies.
I used Sweep because I needed scaling rail to make the shape more consistant as to the thickness (along y-axis)
In Rail Revolve the tips are a lot thiner (along y-axis)

This the one of several petals of a flower thus is it of world coordinates
I am trying to draw jewelry pieces with MOI and Rhino. Some are very organic. I have tried various programm and ZBrush in addition to MOI and Rhino does pretty much all I expect

Could you please advice on how to use Cplane in MOI? This petal I think could be something to learn Cplane in MOI if it works in MOI

Thanks
Olga

Hi Olga, CPlanes are used if you want to relocate the grid to a different orientation than its default world axis orientation.

Say for example you have this model and you wish to draw some new details on the highlighted face:



Notice that face is not aligned with the world axes, so if you were to draw in the regular Top, Front, or Right views it would not work easily to align with that particular face since you would be looking at it in a slanted way instead of looking straight down on it.

You can use a CPlane to help with this - the cplane can orient the grid to match that plane and it can also optionally change the Top, Front, and Right views to be looking straight down and from the sides of that face rather than the world axes directions.

So for this example, using View / CPlane let you place the origin point of the new coordinate system, if you snap it on to the center point of that plane it will align with that plane, like this:



Then after pushing "Done" (or using right-click), the cplane will be set to that orientation, notice how the grid in the 3D view is now aligned with that face:



Additionally the Top, Front, and Right views are now looking relative to that face rather than looking in the standard world directions. So instead of having a slanted view of that face, they have a straight-on view of that face.

Now you can draw (in either the 3D view or the "Top" plan view) new shapes and they will be on that plane, like this:




One other note - MoI actually has the ability to automatically align shapes to planes when you draw them in the 3D view, so it is not always necessary to set a custom cplane to draw just one simple aligned shape to an existing plane, for simple things you can just draw directly on the planes in the 3D view and that plane will behave like a temporary cplane when you snap the first drawn point on to it. But if you wish to get your Top/Front/Right views aligned or do more detailed work on a specific plane or set it at a particular angle or something other than the most basic alignment with the plane, then it can be good to set a cplane so the full grid and views get aligned to it.

It tends to be something used with planar shapes, not really as much with free-flowing shapes like flower stuff though...

Also if your shape does align easily to the world axes, it is also generally better to just draw it aligned to those instead. But sometimes there may be just a portion of your shape that does not easily align to the world axes, that's when a cplane can be useful.

Hope this helps explain it!

- Michael

Hi Olga, it sounds like you are using version 1.0 currently, which is the standard main released version.

But there is a beta (beta means an unfinished test version) release of version 2.0 available that you can download from here:
http://moi3d.com/beta.htm

One of the new functions for version 2.0 is a CPlane function that lets you change the orientation of the grid as I showed above.

There are also a whole bunch of other new things in the v2 beta as well, there is a full list of what is new so far here:

:) For MoI I guess beta really means there are still features to add and not so much about lots of crash bugs to fix...

It actually saves a lot of time for everyone including me to have such a high level of stability.

Hi coy, welcome to the forum!

> Don't know that when I can use edition 2 of moi3d

If you own v1, then you can use the v2 beta right now, you can download it from here:
http://moi3d.com/beta.htm

There will also be a 30-day trial version of v2, but that won't be ready until v2 is completed.
