Hi Alberto - there currently isn't a rebuild command in MoI, you will have to use a slightly different method to get a plane with many points in it to deform.

The replacement method works like this - first draw 2 curves at 90 degree angles, using Draw curve / Freeform / Control points.

Place many points in these curves - each point you place here will give control points to the surface for this method. You might want to turn on grid snap for this, your resulting curves should look something like this (shown here with control points turned on):



Now select one of those curves and run Construct / Extrude. Click the "Set path" button in the command options in the upper-right area of the screen, then pick the second curves as the extrusion path.

Extrude with the "Set path" option has the property that the resulting surface is an exact combination of the control points of each of the original curves. So you can use this method to create a surface with a particular point structure. So your resulting surface will look like this:



So use that to build the original surface there instead of rebuild, and trim it with your outline curve.


> Twist command exist ?

No, sorry MoI does not currently have Twist or Bend type commands, you'll need to use Rhino for these particular manipulations for a while. One quick note - you can move data back and forth between MoI and Rhino very quickly just using copy and paste.
