==Choosing and Placing Parts==
[[RF.Spice A/D]] offers several easy and efficient ways of selecting parts and introduces new tools to make part selection even quicker than ever.
RF.Spice's schematic editor allows you to enter and build up your circuit design very quickly. [[RF.Spice A/D]] offers one of the easiest and most intuitive schematic editors currently available in the market. When building a new circuit, you add parts into the circuit window by choosing them from menus or from the Toolbox or simply using keyboard shortcuts like R, L, C, Q, etc. Then, you draw wires to connect the parts. You will also set properties for the devices to customize their behavior.

You can choose from a list of the most commonly used parts directly from the Parts Menu. This menu is a quick way of selecting a generic or popular example of a type of part. It also contains the basic parts common to most circuits, such as resistors, capacitors, and inductors. Most generic parts have keyboard shortcuts. For example, you can place a resistor, capacitor or inductor by simply typing R, C or L on the keyboard, respectively. Click here for a list of [[List_of_RF.Spice_A/D_Keyboard_Shortcuts | Keyboard Shortcuts]].
<b>Part Palette</b> - The parts palette is a customizable list of parts that you can fill up with your preferred parts. Just select the part from the list of database parts and click a button to fill the palette. The palette is persistent so any changes you make will be carried over even after restarting the program.

[[RF.Spice A/D]] has unlimited levels of undo and redo. To undo any changes to the schematic, use the keyboard shortcut {{key|Ctrl+Z}. The redo any undone changes, use the keyboard shortcut {{key|Ctrl+Y}}.
<b>Naming and Numbering Nodes</b>
Every node in your circuit has a unique number or name. <b>Node 0 is always reserved for the Ground</b>. To display the node numbers or names, click the "Show Node Names" button of the [[Schematic toolbar|Schematic Toolbar]] or use the keyboard shortcut {{key|Ctrl+Alt+N}} or check the Nodes items from the View > Show menu.
Nodes that are connected to each other via a wire get the same node number or name, and so does their connecting wire. Markers can be used to name a node or explicitly set a node number. Place the marker on a node and double-click on it to access its properties. Type in a name or number for the marker and the wire will take on the marker’s name or number. Note that you can place two markers on two different nodes in your schematic with the same name. In this case, you indeed connect these nodes without an explicit wire.
Node names and numbers can also be controlled by either right clicking on the wire and selecting rename node/wire, or double clicking on the node name itself when node names are enabled.

==Schematic Options==
The Schematic Options dialog can be opened from Schematic Editor's Edit Menu and provides a large number of options to customize the appearance and functionality of the Schematic Editor to your personal preference. The dialog has three tabs: Display, General and Print.
The Schematic Display section allows you to customize the appearance of the schematic. "Show Grid" turns the schematic grid on or off. "Show Schematic Border" toggles the top and left location borders. "Show Page Boundaries" shows the printed page boundaries as a dashed line. The printed page size and orientation can be changed from the "File > Page Setup" menu. "Show Title Box" toggles the Title Block for each page. "Show Node Names" toggles whether or not node data is displayed. This is useful for associating data from simulation results with actual nodes in the circuit. All these toggle functions can also be accessed from respective buttons on the Schematic Editor's Toolbar. The "Text Field Font" button sets the font properties for text drawn with the Text Tool. The "Segment Color" and "Vertex Color" buttons are used to customize what colors the wires and vertices are shown in. The node names/node voltages/branch current/power fonts buttons control the various fonts used for the State Display fonts.

<b>General Tab</b>
The Digital Probe and Timing Diagram section controls options for the display of digital signals. You chose between Use (1,0)" or "Use (H,L)" for logic levels, which is used by the Probe Tool to display logic levels on the wires and device pins. The section titled Symbols for New Parts affects new parts that you place in your circuits only. There are three standards to choose from. IEEE symbols are only for the digital parts. US and European symbols are the same in most cases, but differ for resistors and many digital gates and flip-flops.
