Osmond Tutorial Draft Version corresponding to Osmond PCB Design Version 1.0b2 November 30, 2002 J C Chavez http://www.swcp.com/~jchavez/osmond.html jchavez@swcp.com First Page / J C Chavez / jchavez@swcp.com / Osmond Tutorial Basic Part Manipulation This section lets you become familiar with a few keyboard functions and with using some of the basic part manipulation tools in the tool palette. Lesson 1 - Layers Open the Osmond document Sample1 in the usual way, either by double clicking it, or if Osmond is already running, by selecting it with the Open... command in the File menu. A new window should appear with a simple design as shown below. This design has four resistors (R1, R2, R3, R4) and two 14 pin DIPs (U10, U11). Some of the pads have connecting paths, represented as red lines. The current layer is Layer 1. To go to Layer 2, press the 2 key on the keyboard. Don't hold down the command key or any other modifier keyÑjust press 2. As you can see, Layer 2 is similar to Layer 1 but has no connecting paths. This is a four layer board so you can also go to Layer 3 and Layer 4 by pressing the 3 and 4 keys on the keyboard. Try this now. The other way to visit different layers is to use the popup menu button at the bottom left corner of the window. The popup menu lets you go to Layer 1 through Layer 4 but also lets you visit the front and back Silkscreen layers, the front and back Soldermask layers, and the front and back Auxiliary layers. Try going to different layers with the popup menu. To continue with the next lesson, return to Layer 1.

Without clicking the mouse, move the cursor over each of the buttons in the tool palette. As you move the cursor over each tool, a short description of the function of the tool appears in the text field just below the tool palette. Some of these descriptions begin with a single letter in brackets. This indicates that you can select that tool by simply pressing that letter on the keyboard (no command or other modifier keys needed). As you become a power user, you will come to appreciate this feature. However, the normal way to select a tool is to click on the tool button. Let us begin the tools lesson by clicking on the Zoom View button. Note that the cursor now looks like a magnifying glass with a plus in the middle: Try clicking near R1. You will see that the view is magnified and that R1, or whatever point you clicked, is now centered in the window. Now hold down the shift or the option key. The cursor now looks like a magnifying glass with a minus in the middle: With the shift key held down, click near R4. The view is now de-magnified to its original size. However, R4, or whatever point you clicked, is now at the center of the window. You can also use this tool to …
