Solid Body Modelling in Rhino

After understanding and learning how to draft 2D drawings in Rhino, 3D modelling is something that comes in line. It becomes easy for us to view and visualize in 2D and 3D at the same time and Rhino helps with the same. This tutorial is about looking at things in 3 dimensional using basic geometric shapes and volumes.

Developing the 3d of Winton Guesthouse by Frank Gehry, will help us explore various commands in Rhino.

Winton Guest House by Ar.Frank Gehry

1. Creating solid objects

Plan of Winton Guesthouse

To begin with the 3d modelling, create a new layer to work on the 3d.

The plan of the Winton Guesthouse consists of Platonic Solids and can be developed in a couple of ways.

1.1. Using “ Solid Creation” all the basic Platonic solids can be created as required.

To develop the volume of the platonic solid highlighted, “ Solid creation” can be used.

1.1. Extrusion of a plane forms a solid, therefore using the “Solid Creation” command, a cuboid can be extruded as shown below.

1.2. Using a surface to extrude into a volume.

1.2.1 In the plan, curves should be made into surfaces using “Srfpt”.

A surface has been created using “Srfpt” command.

1.2.2. Extrusion of a surface can be carried out as shown below.

Using “ExtrudeSrf” a plane can be extruded to a desired height.

1.3. When two or more solids intersect or overlap each other, “Boolean Operations can be used to make interesting volumes or solids.

These 2 solids can be Boolean-ed together using the “Boolean Operations”.

1.3.1

1.3.2

To Boolean these 2 solids “BooleanUnion” command can be used.

2. Next in line is to achieve solids which are not regular in shape; solids with a an edge at an angel as shown below, etc.

This can be achieved be creating a solid either by using “SolidCreation” command or “Extrudesrf” command.

The slope can be achieved by using “MoveEdge” command. This command help to edit a perfect solid into various interesting shapes.

3. In addition to these commands used to develop the view above, there are a couple of other commands that need to be kept in mind for future use.

3.1 “Scale1D”

“Scale1D” helps us scale selected objects in one axis like in the image on the X-Axis.

3.2. “Scale2d”

“Scale2D” helps to scale a particular object 2 dimensionally.

4. Using Octane Render to render your view, this is one of the views that has been rendered.
