Create a new HCADwin project and draw simple logic: After this lesson you can create a new project, Cut Copy Paste symbols, navigate through all pages, create a New Page, give it a Title, Select a new symbol, give a Tag some extra details. After starting HCADwin or closing the active project you will see the next screen (some screens are updated when using a newer version of HCADwin, but the basic functions always remain): As you can see, only two tool buttons are available: "New Project" and "Open Project". When opening with a menu command you will find some more options, like opening previously opened projects. Try "Options, Select Language" and choose "2" for English. You have to stop and start HCADwin before the new language to take effect. For now, click on "New Project" tool button on the top left corner. This dialog box appears. Give a project name (COURSE e.g.), no path and click OK. You will see the above screen (normally full screen, but this window is made as small as possible). Let me explain what you see. First of all you actually made a copy of the HCADwin.HWI project, which is used as a template. As you can see on the bottom left, page 020 is shown. The other numbers in the white tabs are page 005 (cross-reference page) and page 002 (index page) which have been visited earlier in the HCADwin project (even those attributes are copied). Get rid of the stuff on the first logic page. We want to insert our own logic. As a lesson we are going to use the cut, copy and paste buttons: The cut, copy and paste buttons are grayed. Let's do something about that and delete all symbols (one shown) on this first page: The normal windows keys (Ctrl X, Ctrl C and Ctrl V) will work also. End the copy/paste session by leaving page 020 completely clean. You will still see a border and the four vertical lines. Use the vertical scroll bar to see what the printed page will look like. Pages must have a title. So we provide our empty page with a title. Try a B command. Like all HCADwin commands, just press the key on your keyboard. b or B means the same. In this case the next window pops up, expecting you to fill in an appropriate title for this page, (Please do) and for the first time the name of the engineer (this name will be copied when creating new pages). You could now adjust the revision information. The offsets are used to see the border lines. Only alter them when needed for printing (to punch holes on the sides for instance). HCADwin shows the changes immediately. Use the vertical scrollbar to visit the bottom of the page. The above window shows the new entered information. The HCADwin logo's may be substituted by your own, but I'll come to that later. Actually everything you see can be altered, except for the four vertical lines which indicate this page type "Normal". Notice that the word "Modified" can be seen. It is an indication that this page on screen differs from the one in the HWI file.
Before we will create new pages, tell HCADwin that we are going to use the English language. Find your way through the menu commands: "Edit, Settings" and click on "English". This will change some general texts. It can be undone at any moment. Note that the arrangement of menu commands depends on the HCADwin version. We will start with a new page, say 024. So click the N. And enter the page number. Position the cursor on the middle of the page (near the top) and right click with your mouse. You will see a popup window in which the keyboard commands can be seen which were relevant for this phase of drawing. To Insert a new symbol, select the "I: .." line and click. The symbol selection window will show up. At first it will show the symbol groups with a + sign in front. Click on the "Logic" group for the logic symbols like "And" and "Or". Double click on the group names will do the same. A group will fold again after clicking the - sign or the second double click. Select an "And" symbol. Notice how the selected symbol is shown on the previous cursor position in blue. Try selecting other symbols. After double clicking a symbol, or clicking for the second time on the same symbol, the selection window disappears and the chosen symbol will be moving when the mouse is moved (or cursor arrows are pressed). Note that that the symbol turns black after clicking (or Enter) The above window shows the symbol selection process in progress. The logic symbols are always drawn on grid (a quarter of the grid is shown as the dots). Try the C for Change command with the cursor on the symbol. It will turn green and can be resized.
Add an input symbol (Mnemonic "In") on the page and give it the tag "INPUT1". Connect the input with the And symbol by putting the cursor at the right height en giving a H command. Just inserted the Horizontal line with the H command. Complete the above logic program by adding a second input and an output ("OUT") and connect them with lines. Congratulations! You made your first logic in HCADwin. Don't forget to use the B command to fill in a title like "First AND gate", otherwise the index page doesn't show very much. What we have learned:
