!Circuit
==========
Introduction
------------
!Circuit is an easy to use circuit diagram drawer and editor. Create a
circuit diagram and save it as a draw file to be printed out for your own
use or as a data file to be edited again at a later date. It is ideal for
presentations, school projects and lots of other uses. Text can even be
added to label components. Nearly every component has been incorporated into
this program, in total 100+ components and other essential circuit diagram
elements such as lines.
For those of you who don't read instructions
--------------------------------------------
On a tool/component window, opened either from a menu or from the tool box,
left mouse button (select) selects the component. On the circuit, opened if
a file is loaded or from iconbar, select is used to place an item or text
and adjust is used to delete an item or text. The tool box allows you to
select whether you will place or delete text.
How to use
----------
Double click on the !Circuit icon. If you have a multisync or other monitor
which will support hi-res graphics it is advisable to use a hi-res mode but
this is not essential and users of Arcs with a normals monitor or television
will have no disadvantages as the output quality in draw will be exactly the
same.
When the icon is on the iconbar left click on the icon to open up a tool box
and the circuit window.
The Tool Box
------------
Components
¯¯¯¯¯¯¯¯¯¯
Click on the Components icon to bring up a window containing
all of the circuitry components. Select a component by clicking on it and
then move across to the circuit window. The pointer will then change and you
can place the component on the circuit diagram by clicking select, left
mouse button. The component will be placed on the circuit diagram in a grid.
Lines
¯¯¯¯¯
Clicking on the Lines icon brings up a window containing all the line
symbols. Use this in the same way as the components window.
Text
¯¯¯¯
The Text icon allows you to place text on to the circuit diagram. Click on
this icon to bring up a small window. Write your text in it and then click
left mouse button in the circuit window where you wish to place the text. To
use this function the system must first have seen the !Fonts application.
The default font used in the circuits is Trinity.Medium although if not
present a substitue will be used. Simply double click on the !Fonts
application on App Disk 1 (RISC OS 3 owners needn't bother as the fonts are
built into the systems ROM).
XText
¯¯¯¯¯
The XText icon, next to the text icon but with a big red cross through it,
will change the pointer to a T with a cross through it. Place this over a
piece of text you wish to delete and click right mouse button, adjust, and
the text will be removed.
Clear
¯¯¯¯¯
This icon clears all the data from the circuit diagram. The mouse pointer
will change asking you to verify the action. Clicking select or typing 'y'
or 'Y' will clear the circuit, any other button will escape the option.
The Circuit Window
------------------
Clicking right mouse button on the circuit window will delete the component
that the mouse pointer is over.
Clicking middle button over the circuit window will open the main menu.
The Menu
--------
Size
¯¯¯¯
This allows you to alter the size of the circuit's workarea. To increase the
size press the buttons in the direction of the big red arrows and to
decrease press the buttons in the opposite direction
Scroll
¯¯¯¯¯¯
This allows you to move the circuit around in the work area, usefull if you
wish to move the circuit to add more labels etc. Click on the buttons to
move the circuit in that direction. None of the circuit will be lost, it
will simply scroll to the other side of the circuit.
Tools
¯¯¯¯¯
This allows you to toggle on and off the presence of the tool box. The tool
box will appear if there is a tick by the option in the menu.
Quit
¯¯¯¯
This quits the program. If you still have unsaved data a query box will
open asking if you realy wish to quit with unsaved data in memory.
Saving
------
To save click middle button on the bar icon and go across on 'Save ⇨'. To
save as a Draw file go across on 'Draw ⇨' and drag the draw file icon to a
directory display. Saving it as Data means that it can be loaded back into
the program to be edited at a later stage. You can drag either into an
appropriate application directly.
Loading
-------
To load drag a Ciruit file (file type &00C) to the Circuit icon on the
Iconbar. Double clicking will also load a file into the program or if the
program is not present will load the program automatically.
