INTRO TO SURFACES IN Rhinoceros, CONTRUCTION PLANES IN Rhinoceros REVISITED

one. SURFACES

Load the file Classes\Arch3410-6410-Mark-F11\Examples\surfaces\surfs.3dm. In the Primary tool box, click and hold the surface icon to open up up the Surface modeling tool box then click and hold the solids icon to open upwardly the Solid modeling tool box, and employ the tool specified in each example of a surface type entity as indicated below.

Surface and Solid of Extrustion
Select Extrude Straight from the Surface toolbox (meridian right icon below).

Select the rectangle in the upper left mitt corner, and then press enter to interactively extrude it along the Z axis.

Select Extrude closed planar bend from the Solid tool box (bottom right icon below)

Select the rectangle in the upper left hand corner, so press enter to ineractively extrude information technology forth the Z centrality.

Notation the solid by extrusion is filled in, wheras the surface by extrusion is an open container.
Select the Surface from 2, iii or 4 Edge Curves icon from the Surface tool box.

Printing enter and then select in clockwise or counter-clockwise gild the four edges assocaited with the effigy below, once the 4th edge is selected the surface will automatically be generated.

The same tool applies to ii parallel edges. Two initial cuved bspline established the edges used to generate the effigy beneath. Each one of the initial bspline edges was selected to the same side of their respective mid-points, then enter was pressed to generate the surface below.
Surface and Solid of Revolution.
The Revolve Surface icon is selected from the Surface tool box as shown below. The profile curve is selected by clicking on the curve and pressing enter, followed by stop snaps onto the vertical axis line and finally pressing enter to set the start angle. The curve can then be interactively swept well-nigh the axis or swept a full 360 degrees by pressing enter a last time.

The aforementioned technique also applies to a an open contour curve.
Tubular Surface
A tubular surface is obtained past the apply of the Sweep 1 rails tool.

The start choice for this tool is used in the case of simple line along the ground and a 3D contour curve. Select the profile bend, the horizontal line along the footing, so enter to bring upwards the Sweep runway 1 options dialog box.

Skin Surface

The aforementioned tool from before can be used to sweep 2 curves along ane profile curve.

The cases below involve the employ of like techniques of sweeping 2 curves along a contour bend.


The Sweep i track icon is selected followed by the path curve	select the 2 profile curves

enter brings up the tool for adjusting the curve directions, make sure both arrows face the same direction.	enter again brings upwardly the options dialog, press ok to complete the surface.

The Sweep 1 rail is selected for the example above.	Select the two profile curves and enter to bring upward the options dialog, enter again to complete the surface.

A variation on this type surface involves sweeping ii curves along two curves.

The to a higher place operations produce the post-obit result:

ii. Coordinate Systems in Rhino

When drawing in Rhinoceros, objects are snapped into a 2d invisible plane called a Construction Plane or CPlane. In perspective view if you are near the origin of the model space and filigree is turned on (default) you tin come across the CPlane as the filigree with the X and Y coordinates represented as scarlet and greenish lines on this grid respectively. In the bottom left of this image is too an icon that shows the Global Coordinate System relative to the view window.

CPlane = Structure Plane, the invisible 2D plane which data points are snapped to. Changes relative to the dissimilar views.
Global Coordinate System = Represents the XYZ orientation of the model. Does not alter relative to the unlike views or CPlanes. Past default, information technology is co-planar with the CPlanes.

5. Manipulating CPlanes and coordinate systems.

i. CPlanes in Rhinoceros can be moved or rotated to any orientation to let for amend control of drawing in the model space

Setting CPlanes in Rhino

- Click and concord on the icon in the Chief button bar called Set CPlane : origin to open the Coordinate Organisation bar as its own window. Then Click and agree the first icon in that bar to open upwards the Set CPlane bar every bit some other independent window.

In perspective view describe a simple box, notice how the data points defining its length and width default to the Grid of the CPlane. Now draw another box starting in the side view away from the origin, notice its position once extuded in the Perspective view off of the Perspective CPlane.

ane.1 Translating the CPlane

Click on the first icon in the Set CPlane menu box labeled Fix CPlane Origin.

Then motility the Origin of the CPlane in the perspective view anywhere in the model, even snapping to objects or other points. Now drawing in Perspective view volition snap all data points to this new construction plane.

Moving origin to a snap point on another object.

At anytime click the icon labeled Previous CPlane to navigate changes made in the CPlane.

Returns to last Construction Plane used.

Apply the Second icon labeled Set CPlane Elevation to just move the CPlane in its relative Z axis, and click to accept.

1.2 Rotating the CPlane

Use Set CPlane: Rotate to rotate the Perspective CPlane xc degress virtually the Y axis.


Cull Ready CPlane: Rotate with the Perspective view selected.	Hit enter to fix the rotation axis at the origin.

With ortho on cull a point in Top view above the origin to set up the axis.	In Front view click to the correct with ortho to set the kickoff rotation.

Then click above to rotate the CPlane 90 degrees.	Now in the Perspective view you can see the grid is oriented in the ZY plane.

Render to the original CPlane by clicking on the Previous CPlane icon.

Next use the Set up CPlane by 3 points icon to create an orientation relative to a diagonal on the box.


With Perspective view selected click Set CPlane by 3 Points	With snaps on click on ane corner of the box to set the origin

Click on another corner to set the 10 centrality	Then click on a third corner diagonal from the others to fix the Y axis

This sets the CPlane through the box diagonally.	Drawing another box in Perspective view.

Other methods of manipulating CPlanes.

Prepare CPlane to Object

Sets the CPlane in-line with a role of an object, with the origin at the object'southward center.

Set CPlane to Surface

Sets the CPlane tangent to a point on an object'south surface.

Set CPlane Perpendicular to Curve

Sets the CPlane's X and Y axes perpendicular to a betoken on a bend.

Ready CPlane to View

Creates a CPlane relative to the photographic camera'due south viewing angle

two.one Organizing created Coordinate Planes.

To save and load CPlanes.


Select the view and click Named CPlanes...	this brings up the Named CPlanes dialog box

Click Salvage and type in a proper noun for the CPlane then hitting OK	now the CPlane "Diagonal_1" can be referred back to later on.

Alternately you can click the Salvage CPlane by Name icon, type a proper noun and press enter to relieve the selected view's CPlane.

The Named CPlanes dialog box can exist used to restore saved CPlanes to the selected view by choosing the view and clicking Restore.

the highlighted CPlane is displayed in the view window as colored arrows.

Clicking Restore applies the selected CPlane to the Viewport.

An alternating method to this is to right click the Salvage CPlane past proper name icon and blazon the saved CPlane'due south name then press enter.

2.2 Preset CPlanes.

These six icons in the bottom right of the button bar will utilize a CPlane to the selected view that is relative to
the Global Coordinates :Meridian, Lesser, Front, Back, Right, Left orientation respectively. This is an constructive way
to pull upwardly normally used construction planes quickly and easily in the model space.

2.3 Mobile Construction Planes

A terminal method of manipulating the Construction Planes is to attach it to an object and have it always update relative to that object.


In Perspetive View use the Previous CPlane icon to render to the default.	In the Structure Plane tool box click Ready Mobile Construction Plane

Select the diagonal box and press "A" enter to attach	select one corner on the box to fix the origin

select the other 2 corners to set the X and Y axes	Press enter for automatic updates to the CPlane.

Rotating the object rotates the attached CPlane likewise	Translating the object will translate the CPlane
