Accessing Electra options
Electra comes with drawing options that allow engineers to select/deselect the automated tool needed.
To access Electra options, go to File and select Preferences, a pop-up dialog will be shown, as below:
Go to Electra Options and check/uncheck the options that work best for one’s needs.
Automatic in/mm/cm/meters resize
Electra has the ability to automatically resize symbols and circuits to fit onto pages, irrespective of the page measurement units used, be it inches, millimeters, centimeters or meters.
Enable this option to let Electra automatically resize symbols and circuits to fit onto pages. When enabled, symbols and circuits that is manually resized by users will retain their sizing and will not be automatically resized by Electra.
Automatic wire propagation and detection
Enable this option to let Electra automatically propagate wire name changes to all connected wires and automatically detect a wire name when it is connected to another.
Disable this option to have different wire names for wires with the same potential.
Split wires when dropping terminals
Enable this option to let Electra automatically split wire into two when terminals are placed on wires.
Automatic adjust and straighten wire
Enable this option to let Electra automatically straighten slanted wires when connected to another. Disable this option to keep wires in drawn position.
Automatically manage connection dots for wires
By default, Electra has the ability to automatically manage connection dots for wires.
Enable this option and Electra will automatically show dots for a connection, and remove them when there are no connections.
Connection dots are also automatically hidden when you connect a wire end to another.
Disable this option to manage connection dots manually.
How page prefix works
Page Prefix in Electra is powerful and automatic. Once enabled, Page Prefix adds a page number in front of your symbol reference or wire name and automatically keeps track and update this page number even when you rearrange your pages, all automatically.
On the example above, there is a coil named 1R1 on page 1, another coil 2R1 on page 2 and 2 contacts, each of them belonging to the coil at page 1 and 2 respectively (top row of the image).
When page 3 is rearranged as page 2 (bottom row of image), the coil 2R1 previously at page 2 is now automatically renamed to 3R1 on page 3. The contact 2R1 is also renamed to 3R1 since the coil it is belonging to, is now renamed to 3R1 on page 3.
Enable page prefix on references
Users can select to prefix a page number on all symbol references by enabling this option, and Electra will automatically insert and maintain all page prefixes. Alternatively, right click on a symbol and select "Edit Reference" to use Page Prefix.
Enable page prefix on wires
Users can select to prefix a page number on all wires by enabling this option, and Electra will automatically insert and maintain all page prefixes. Alternatively, right click on a wire and select "Edit Wire" to use Page Prefix.
Page prefix separator for wires
The default separator for wires is the "." character (e.g. 1.100). Page prefix separator for wires can be any character but cannot be numeric (e.g. 0-9) and can consist of more than one characters.
Automatic wiring when dropping symbol
Enable this option to speed up the process of drawing schematic diagram by connecting the symbols automatically when a symbol is dropped next to another symbol.
The stencil that contains Wire, Hose, or Tube is required to be expanded when connecting the symbols. Disable this option to prevent automatic wiring between symbols.
Automatically Place Layout Symbols on Rails
Electra has the ability to automatically attach and arrange layout symbols when dropped on rails. Uncheck this option to disable automatic placement of layout symbols to rails globally.
Alternatively, each layout symbol can be individually disabled from automatic placement by right clicking on the symbol and choose Disable automatic placement.
Initial Placement Offset
When layout symbols are placed on rails, Initial Placement Offset specifies the distance between the edge of the rail and the first layout symbol.
Location zone options
Electra reports shape locations (e.g. /1.A1 : Page 1 - zone A1) by dividing a drawing page into zones. To modify the location zones, click on File | Preferences | Location and enter your preferred zone spacing.
- A: Denotes the starting spacing for vertical zones.
- B, C: Denotes the repeated spacing for vertical zones.
- 1: Denotes the starting spacing for horizontal zones.
- 2, 3: Denotes the repeated spacing for horizontal zones.
To configure how Electra displays location information, use these options:
- Page: Denotes characters used to prefix page numbers.
- Separator: Denotes characters used to separate page numbers and location zones.
