1. Introduction
1.1. What is the Component Modeller?
The Component Modeller is a model building element in the <Virtual
Environment>. It allows the user to create a library of components which can
then be placed within the model. Components are geometrical entities and can
be used to model things such as desks, chairs, computers, etc. These can then
be placed in the model by ModelIT. The Component Modeller uses many of the
same drawing and editing tools that are used in ModelIT.
Components can be created by the Component Modeller, imported from a
standard library or from another project. IES provide a number of libraries with
commonly used components. At present the defined colours (RGB) of the
objects within a component are read into Radiance.
1.2. Using This Guide
This guide introduces the terminology used to describe the Component
Modeller and includes a description of all the features i.e. toolbars, pull-down
menu items and pop-up windows.
This document is intended as a Reference Manual and users may find the
Component Modeller Tutorial Manual an easier introduction to running the
software.

2. Fundamentals
2.1. Projects
When the <Virtual Environment> is started up a blank project is initialised and
the “ModelIT” workspace is activated. To enter the Component Modeller click
on the “CompLib” button in the “ModelBuilder” tab. This can be activated at any
point in the creation/editing of the model. For more details of
creating/opening/saving projects see the document General Help Topics
section 3.
The viewport area may be white, with the grid in black, or in any other colour of
the user’s choice.

2.2. The Component Modeller Workspace
The sub-window you are now looking at is the Component Modeller
workspace.
The workspace is divided as follows:
2.2.1. Pull-down Menu Bar
This provides an alternative method of accessing the functions available on the
various toolbars.
2.2.2. Model Toolbar
This contains functions mainly associated with creating components.
VE 2015

2.2.3. Edit Toolbar
This contains functions mainly associated with editing components.
2.2.4. Viewport
The viewport window can also be used to show two or four viewports, see the
ModelIT documentation for more information.
2.2.5. View Toolbar
This contains functions mainly associated with viewing models. For more
information on this tool bar please refer to General help topics user guide
section 2.3.4.
VE 2015
Component Modeller

2.2.6. Object Bar
This contains information associated with the current object.
The “Object Bar” and toolbars can be switched on/off and the viewport options
selected from the “View” pull-down menu. Please refer to ModelIT user guide
section 2.4 for more information.
2.3. Levels of Decomposition
This works in a similar but more restricted way to what is available in ModelIT.
Please refer to ModelIT user guide section 2.6 for more information.
2.4. Toolbars
The toolbars save you time by enabling you to select some of the most
frequently used commands, without having to select them from the pull-down
menus at the top of the ModelIT window. Each toolbar is described below from
left to right.

2.6. Component Browser
When the Component Modeller is entered for the first time a default component
is created with no geometry as yet:
The four functions available are:
Create New Component
Copy Component
Remove Component
Add Component from Library
2.6.1. Create New Component
When this button is clicked a new component is created:
Note that this new component also has the default name “Component”, it is
advisable to change this to a more meaningful name.
VE 2015
Component Modeller
10
2.6.2. Copy Component
When this button is clicked a copy is made of the current component:
This is useful where minor variations of a component are required e.g. the same
component with different colours applied. Again it is important to change the name of
the component to fit its definition and avoid confusion.
2.6.3. Remove Component
This will delete the current component from the library. A warning message is
displayed:
Note that the last component cannot be deleted i.e. the library must contain at least
one component.
VE 2015
Component Modeller
11
2.6.4. Add Component From Library
This is probably the most useful of the options. It allows the user to get an existing
component from another model or from a standard library. The following window is
popped-up:
By clicking the “File” button the user can browse to find an existing component
library. Components can be selected and added to the current component library.
Components can be customised to the requirements of the current model, either by
changing the geometry or by editing the colours.
2.6.5. Properties
If you right click a component in the Component Browser and select Properties you
VE 2015
Component Modeller
12
can change the name and Category of the component.
Standard means the component can be placed in ModelIt using the Place
Component button.
CFD means the component can be used in CFD analysis.
Opening adds the component to the Add Opening dialog that is displayed in ModelIT
when an opening is placed at model level.
The Component Modeller Tutorial details how to create an Opening Component for
use in ModelIT.

3. Model Functions
This section looks at functions associated with the Model toolbar. We shall
describe only those options which differ from ModelIT.
3.1. Draw Extruded Shape
(“Draw”  “Extruded Shape”)
Pops-up the following window:
Selecting this command allows you to create an extruded shape as a series of
straight-line segments. Select each point of the shape in turn, in either
clockwise or anti-clockwise order. To close the shape, click on the “Close
Shape” button which is active while you are drawing the shape. If you make a
mistake and need to undo a point, click on the right mouse button. The current
lock settings will apply and key-in values can also be used. The extruded
shape will be created with the defined Plane (m) and Depth (m) values as
currently set in the Shape Settings dialogue box. An extruded shape can be
created along any axis.
Note that you cannot cross a segment with another segment and you cannot
place a perimeter point on an existing perimeter point unless it is the first point
in which case this will close the shape.
The relevant key-ins for the extruded shape are: x=<x, y>, dx=<dx, dy> and
p=<length, angle>.
VE 2015
Component Modeller

3.2. Draw Plane
(“Draw”  “Plane”)
Pops-up the following window:
Creates a plane at the given height. This function is not available in ModelIT.
The relevant key-ins for the prism are: x=<x, y>, dx=<dx, dy> and p=<length,
angle>.
3.3. Draw Prism
(“Draw”  “Prism”)
Pops-up the following window:
Selecting this command allows you to create a prism shape. Select the point
VE 2015
Component Modeller
15
where one corner of the prism is to be located, then select the point that is at
the opposite corner of the prism. A new prism will then be created with the
defined Plane (m) and Depth (m) values as currently set in the Shape Settings
dialogue box. A prism can be created along any axis.
The relevant key-ins for the prism are: x=<x, y>, dx=<dx, dy> and p=<length,
angle>.
3.4. Draw Pyramid
(“Draw”  “Pyramid”)
Pyramids are created in a very similar way to extruded shapes except that after
completing the perimeter, you will enter a point to define the apex of the
pyramid.
Pops-up the following window:
Selecting this command allows you to create a pyramid shape. To create
pyramids, you must first define the shape of the base of the pyramid and then
position the top of the pyramid. To define the pyramid base, select each point
on the perimeter of the base in turn, in either clockwise or anti-clockwise order.
To close the shape, click on the "Close Shape" button on the Shape Settings
dialogue box which is active while you are drawing the shape. Next, select the
position of the top of the pyramid. A new pyramid will be created with the base
at the defined Plane (m) value as currently set, and the top point at the Plane +
Depth (m) values as currently set. A pyramid can be created along any axis.
The relevant key-ins for the pyramid are: x=<x, y>, dx=<dx, dy> and p=<length,
angle>.
VE 2015

3.5. Draw Sphere
(“Draw”  “Sphere”)
Pops-up the following window:
Selecting this command allows you to create a spherical shape. To create a
sphere, first select the centre of the sphere and then select a point which
defines the radius of the sphere. A new sphere will be created with its centre at
the defined Plane (m) level that is currently set in the Shape Settings dialogue
box which is active while you are drawing the shape. The number of chord
segments which make up the sphere is defined in the Shape Settings dialogue
box. A sphere can be created along any axis.
The relevant key-ins for the sphere are: x=<x, y>, dx=<dx, dy> and p=<length,
angle>.
VE 2015

3.6. Draw Hemisphere
(“Draw”  “Hemisphere”)
Hemispheres are created in exactly the same way as spheres.
Pops-up the following window:
Selecting this command allows you to create a hemispherical shape. To create
a hemisphere, first select the centre of the hemisphere and then select a point
which defines the radius of the hemisphere. A new hemisphere will be created
with its base at the defined Plane (m) level that is currently set in the Shape
Settings dialogue box which is active while you are drawing the shape. The
number of chord segments which make up the hemisphere is defined in the
Shape Settings dialogue box. A hemisphere can be created along any axis.
The relevant key-ins for the hemisphere are: x=<x, y>, dx=<dx, dy> and
p=<length, angle>.
VE 2015
Component Modeller
18
3.7. Draw Cylinder
(“Draw”  “Cylinder”)
Cylinders are created in a similar way to spheres and hemispheres.
Pops-up the following window:
Selecting this command allows you to create a cylindrical shape. To create a
cylinder, first select the centre of the cylinder and then select a point that
defines the radius of the cylinder. A new object will be created with the defined
Plane (m) and Height/Depth (m) at the values currently set in the Shape
Settings dialogue box which is active while you are drawing the shape. The
number of chord segments which make up the cylinder is defined in the Shape
Settings dialogue box. A cylinder can be created along any axis.
The relevant key-ins for the cylinder are: x=<x, y>, dx=<dx, dy> and p=<length,
angle>.
3.8. Component Handle
This sets the “handle” point of the component.
Note: the option to move the component handle is no longer supported in
Component Modeller, the default handle used in <VE> when placing any
component is at the origin point (0,0,0).

and assigns default attributes to the geometry.
6.2. Export GEM File
This option exports the geometry created by the Component Modeller, to the
GEM file format.
7. Component Libraries
There are a few basic components that you can use or edit in the default library.
These standard libraries are installed (by default) at the following location:
