Nurbs Geometrical spline that defines surfaces Advantages

when you want to edit it is really easy to change shapes

Commands Rhino Working file 1

Right for rotating
Left for selecting
Shift+ Right pan
Cntrl+ Right zoom
Alt + Right Zoom
Shift+alt+right Tilt

If you make want a make a line in vertical

Command line / press control while click again in the initial point/ now your line is in the Z axis

3d curve by pressing control and clik for control point

CONTROL+SHIFT+LEF Select FACE
Change the line of dots/dash lines _ setlinetypescale

and change the values until you see it nicely

SEAPLANE = working table

Double click on the viewport type(perspective,top,etc)To full screen it.double click again to return to 4 views

Tools/options all configuration of Rhino

Lens recommendation ( right panel)

50mm
35mm

Filter

To allow you select only what it is active

Gumball

Scale/Rotate/Move Double click on it to allow you to introduce units

+Shift it will do it proportional

Click on the white cirle with left click to relocate gumball and put the new axis.

Press Cntrl after moving to create a surface from curves

if you want to toggle the control points of a curve you can use CONTROL POINTS by activating F10-F11

Rebuild

Will allow to add control points. When the context menu appear you got points and degree. Points= for number of control points Degree= for angled or curved, the same as curved.

Will work for curves, surfaces, lines, etc

_InsertControlPoint for new lines of control(increment the lines in some areas, you should turn off f10-f11)

SolidPtOn

To edit the control point of a solid object without exploding If you use explode you can finish with an open objet.

Cagedit

Boundy box for make a point of cage to deform solid objects

Surface Tools Rhino Working file 2

You can check the normal of the surfaces
Command _dir

Making the surface clockwise is the opposite as counterclockwise, one will be backside up.

Closed Surfaces

The only closed surfaces(naturally) are the sphere and the torus as the controlpoints/corners are supperposed above themselves.

Trimed Surfaces

If you trim a surface the control points of the biggest surface keep steading there.

If you want to shrink the point to adapt to your new surface you should apply the _SHRINK COMMAND (righ image)

3-4 Points Surfaces

It is not the same a:

surface made with 4 control points (left)
surface made with 4 control point (center) the initial is the same as the final
surface with 3 control points ( right) the 4 point it is a ghost.

Surface that is turned back you can “flip” it COMMAND

Duplicate borders

To extract the permiter from a surface _DupBorder

Surface from curves

You create for example 3 close curves Intersect them with some planes and select everything for _intersect Erase the planes and you can see the points in the intersection

Now you can join the point with some curves

Curve - Interpolate points(inside curve)

And create the surface with surface/ create surface from network of curves.

Surface from borders,etc

Patch command

Stiffness

lower numbers make it more loose
if it is to stiff it could not adapt to the corners,lines,curves,etc

Automatic Trim will show you the whole original trimed surface in case you have it

Adjust tangency when you want to fill the hole or trimed part with a surface that it is in another surface

Sweep

Drag seam point means where to start

You need a main guiding line and a profile to follow that lines You can move the CPLANE to the curve to create a profile perpendicular to the guiding line.
