2

It’s an easily used software programme

for designing and estimating

electrical systems for residential and

service industry applications

What is GWCAD for?What is GWCAD for?

3

It enables installers and

designers to produce:

- location plan drawings of the building part

- drawings of the electrical system

- a distribution layout (including accessories)

- calculate lighting requirements

- a list of materials

• This is a programme that works independently (AutoCAD not required)

• The programme has a two-dimensional CAD engine with all the main AutoCAD commands (layer, grid, filters, block management, etc.)

• It is possible to import and generate “dwg” and “dxf” files

• Drawings and images in the usual formats (bmp, jpg, wmf, etc.) can be imported and used for designing the system

GENERAL FEATURES

12

On starting up GWCAD, it is possible to adjust the worksheet by choosing:• format;• direction of the worksheet;• scale;• measuring unit.

SETTINGSCALE AND PAGE

13

“FILE” COMMANDS In the “File” menu there have been included the commands for• managing files (New, Open,

Save, etc.);• settings of the drawing sheet;• printing settings.

Specifically:- the “Import-Export”

command enables importing drawings in the AutoCAD formats “dwg” and “dxf”;

- the “Preferences” command enables setting:

> the background colour> the measuring unit> variable aspects> the menu bars

14

At “Edit” in the menu bar it is possible:• to duplicate• generate a series• move• turn• mirror• scale(…)the elements drawn, in the following way:- launch a command;- select the element to be

In “Tools” there are various commands:• grid management;• management of styles;• filters for precision drawing.

In detail:continued...

“TOOLS” COMMANDS

17

…

- the “Ortho” command is for drawing and shifting elements vertically or horizontally;

- the Grid is a network of points (the distance between which can be set using the command “Grid”) which enables making precise drawings; these points can also be “magnetised” (they can bind movements while drawing) by activating “Magnet on grid on-off”

- with the “Textstyle” command, the text can be differentiated using Windows fonts

“TOOLS” COMMANDS

18

In “View” there are various commands for displaying the drawing.

Specifically:• the “Zoom” command is for

enlarging a detail in the drawing, and is used by:- launching the command;- click on the upper-left

corner of the detail to be enlarged;

- click on the lower-right corner of the detail to be enlarged,

• the command “Zoom Extension” is for seeing the whole drawing on the screen

Electrical symbolsIn the library there are symbols associated with GEWISS products, and symbols for non-GEWISS products:• select the icon “Symbols

library”;• select the category of symbols

(Luminaires, sockets, Domestic series – terminals, etc.)

• select the electrical symbol• select the series and device at

A dialogue window appears for establishing the type of fitting and the plate wanted

Once the composition has been created, the accessories will be added to the list of materials


28

Further commands relating to the Domestic series

Device properties: for changing the type of device inserted

Explode composition: for cancelling the operation for calculating domestic series accessories so as to return to the original devices without accessories

Number boxes: to number the boxes and get a list of components in which there is the reference to the box they come from

Change serie-installation-cover plate: to change the plate and/or fitting and/or Series of components inserted.For instance, a system can be made up using components from a certain Series (Black System) and, afterwards, you can decide to convert all the components inserted in the drawing in the same ones from another Series (Playbus). Any products that have no corresponding elements in the new series are signalled, and the products from the original Series retained

Defining symbols scale

The command Set composition makes it possible to set a scale for all the symbols, so that they can be inserted proportionally into an imported location plan (for instance). The symbols can be larger or smaller, increasing and decreasing the amount in the “Correction factor for fixed blocks”.


31

Duct choiceYou can lay out a distribution route (tubes or channels)

Select the command “Distribution layout” and click inside the location plan at the initial point of the distribution layout. A dialogue box enables:

• setting the initial height above ground and the width;

• choosing the tube/sheath etc.;• adding new lines already

defined or create new ones as required.

Distribution layout


32

Duct designOnce the choice of duct has been made, its route can be laid out by moving the mouse to the point wanted and clicking on its left side.

While drawing, there are shown:• the length of the section• the height from the floor.


33

Duct designThe duct can be designed virtually at various heights above ground by using the command “Upward”; this can be activated while designing the distribution by clicking on the word “Upright” to the left of the command bar.

The points where the duct rises/descends are marked by an arrow


34

Displaying ducts

Using the command “ASSONOMETRIC PROJECTION” it is possible to get a 3D view, generating an image after having defined the two coordinates and traced round the area to be projected:

Regarding the electrical components drawn, a list of materials can be prepared

The list can be:• Whole drawing (regarding the

to the active layers)• Selected (based on the area

selected)

43


Regarding the components in the domestic series:• in the list of materials it can

be decided to take account of the cables and tubes that the programme automatically inserts in the composition;

• the various components can be grouped by box, so as to have for each element the reference to the composition.
