    GEO118 exercise 2winter, 2003 due:week 3, beginning of lab

    Freehand Tutorial

    For the first few lab exercises we will use a graphics application called Macromedia Freehand.Freehand is a vector-based graphics package widely used in cartography and graphic design shops.Vector graphics contain graphic objects or shapes that are made up of lines or curves called vectors.Raster graphics are the other graphic type on which graphics software can be based. We will talkabout these in a few weeks, but all you need to know for now is that raster images are made up oflittle squares called pixels. Pixel stands for picture element, the smallest unit a raster imagecan contain. Raster based software always reference individual pixels rather that objects or shapes.

    Accessing the class file server

    All the files you need for this lab will be located in a directory on L: called Geog118. To access

    this directory, do the following:

    Open Lab##(where ## is the number of your computer)and double click labs on UBAR

    (L:) Double click on the folder called Geog118. Double click on the folder called Handouts.

    There will be a file called FHTutorial.fh10 in theweek02folder. Copy this file to yourdesktop by dragging the icon to a clear green spot. The file you just copied is an unfinished mapof the Boulder, Colorado area.

    Freehand

    Double click on the file that you copied to you directory. Since it is a Freehand file (.fh10),Freehand will automatically open. It takes a little time, so be patient. When it opens fully youshould see the beginnings of a map. What you are looking at is the Boulder, Colorado Countyboundary with various roads and rivers on it.

    Selecting and Deselecting

    Take your mouse and select the boundary of Boulder County by clicking once on it. Notice thefour black squares that appear when you click on it. These squares tell us that the boundary isselected. Click on a blank place on the page to deselect it or press TAB. Now try selecting anddeselecting some of the roads and rivers. Make sure you know when they are selected anddeselected.

    When an object is selected you can move it around, delete it, change its color, or do a number of

    other operations on it. Try moving the boundary a bit, by clicking and dragging it a bit to theleft. Go to the menu items and select EDIT, the first choice under this item is UNDO (whateveryou just did). If you moved your boundary line and want it back to its original position selectUNDO MOVE. You can use undo to reverse your actions one by one. The number of undos canbe set under EDIT and PREFERENCES. You have many undos, but dont depend on them!

    If you want to select more than one object, you can click on the first item you want to select, holddown the Shift key, and select a second item. This is called shift clicking. Try selectingmultiple roads and rivers. Make sure you are comfortable with shift clicking.

    Magnification

    Make sure your Tools palette is open. To do this go to the Windows menu andmake sure there is a check mark next to tools. The toolbox should be visible on yourscreen, and look like this...

    Select the magnifying glass icon by clicking on it with your mouse once (on right, nearbottom). You can use this to zoom in and out on the map. Notice after you click on ityour mouse cursor now looks like a magnifying glass rather than a pointer. There aretwo ways you can use the magnifying glass. You can simply click any place on the mapand it will zoom in on that spot. If you click again, it will zoom in even further.Notice that on the lower left hand corner of the screen, it will tell you percentage of

    magnification. To zoom out simply hold the ALT key on your keyboard whileclicking on the map, (Alt click.) Notice that when you do this your mouse cursorchanges to a magnifying glass with a minus sign in it. Also, notice that as you zoom outthe magnification percentages decrease.

    There are other ways of changing the magnification. While you still have the

    magnifying tool, drag a box around the whole map. This is one method of magnifyingso that a specific area is under magnification. It also fits a particular area of your mapto the screen. Practice this method of magnifying a bit.

    Another method of magnifying is under theVIEWand MAGNIFICATIONmenu.You can choose any magnification from this list. In addition there is a menu to choosemagnification in the lower left hand corner of your screen.

    You can type any magnification you would like into the magnification window. Inaddition, you can click and hold on this arrow shown above to get a menu ofmagnifications. If you ever lose your map try using this menu to magnify to FIT PAGE. Thiswill center the page on the screen.

    Layers

    Layers are a key feature of a good graphics package. It is important to know how to use the layerspalette in order to organize your map and control what can be selected and what cannot. To access

    the layers palette go toWINDOW,PANELSand select LAYERS. You should see a layerpalette on your screen that looks like this:

    Right now everything on your screen is in one layer, theForeground layer. Click on the check mark next to theForeground layer. Notice that when you click on the checkmark, it disappears, and so does your map! This check markcontrols what is visible on your map.

    Make the map visible by clicking in the space where the checkmark was originally. The check mark should reappear, and so

    should your map. Now click on the lock icon next to the foreground layer. When you click onthis notice that the lock closes. Now try to select something on your map. You shouldnt be ableto select anything. This is because when the layer is locked it cannot be selected. This is one wayof protecting your map. When objects are locked they cannot be changed in any manner. Nowunlock the foreground layer by clicking on the lock.

    We want to make three new layers. We want a roads layer, a rivers layer, and a parks layer. First,click on the right arrow atop the layers window (highlighted in red on previous page). A newmenu should appear.

    Choose new from the menu. You should get a new layer in the palette called Layer-1. Double

    click on Layer-1 and type the new name Roads and hit enter. It is very important to hit return.If you do not, your typing will not register on the layers palette.

    Now we need to add all of the roads to this layer. Right now all of the roads are on theforeground layer. Select your pointer tool (top left of tool palette) and shift-click all of the roadsthat you can. Then click on the Roads layer. This automatically moves all of the roads that you

    selected to this layer. To see if it worked click the check mark next to the Roads layer. Look atthe map, did all of the roads disappear? If you still have some roads visible on the map thatmeans that they are not on the roads layer, which is not visible. Select the remaining roads andclick on the Roads layer. Make the Roads layer visible and invisible by clicking the check markon and off. Are all the roads on the layer? Once you have all of the roads on the roads layer, lockthat layer by clicking on the lock icon next to the roads. Now you will not be able to select anyroads until you unlock that layer.Now do the same thing with the rivers. Under the arrow menu, make a new layer. Click on thenew Layer-1 in the layers palette, type the new name Rivers and hit enter. Now add all of therivers to this layer, by shift-clicking to select multiple rivers. Click on the Rivers layer to addthem to this layer. Use the check mark to determine if you have successfully added all of therivers to this layer. When the Rivers layer is complete, lock it.

    We have one more layer to make, and this is the Parks layer. Do the same as above to add a newlayer named Parks. Click on the three polygons on the far left of the map; these are the Parks youwant to add to the layer palette. Once they are added to the Parks layer, lock that layer as well.The remainder of the map information can remain on the foreground layer. If you would like, youcan rename this layer Basemap.

    Saving

    Lets save what you have done so far. Go to FILE in the menu options and choose SAVE AS. Awindow will appear asking you where you want to save the file and what you would like to nameit. You can save your file temporarily on your desktop. Click the down arrow next to where it

    says personal and scroll to the top of the list. Select Desktop from the list. Now name yourfile with your last name.

    Drawing Lines and Curves

    There are several roads missing from your map. One is the Diag, the Diagonal Highway(Hwy119) that runs from Boulder to Longmont. The other is at the west end of Table Mesa which runsup to NCAR (curvy road starting where the brown star is).

    First lets draw the Diag (where the green diamond is). Make sure all of your layers are lockedexcept for the Roads layer. Since we are drawing a road, we want it to sit on the Roads layer.

    Click on the line tool (see image below).

    Notice that your mouse cursor has changed again from an arrow to a cross bar. Clickand drag to draw three sections of lines like those below connecting BoulderandLongmont.

    Use the map above as a guideline. We are just practicing some of thetools in Freehand, so it doesnt have to be geographically perfect.

    Okay, lets try another tool used for drawing lines. Click on the Freehand tool.(See picture)

    Try drawing a squiggly line by simply clicking and dragging the mouse. Trydrawing a curvy road
