GRAPHICS TUTORIAL # D3Creating and Editing Graphic Information In Adobe Illustrator

CP-208 Plan Preparation Studio - Prof. Elizabeth Macdonald 2

In this tutorial we will learn two things: First, Creating a Land Use map and second, highlighting areas with color areas of aerial photographs and plans. A. Creating a Land Use Map from a Block/Parcel Map Using Adobe Illustrator

STEP - I. Creating a New Layer for the Land Use Map:

1. OpentheAdobeIllustratorfileyouhavecreatedinTUTORIAL # D1, which contains the title block template.Asthisfileisatemplate,whichmaybeneededlater.Toretainit“saveas..”,givethenewfile anameofyourchoice,andsaveitinanappropriateplace.2. ClicktheNewLayerbutton( )onthebottomoftheLayerspaletteorchooseNewLayerfromthe Layerspalettemenutocreatealayerwithdefaultoptions.Thenewlayeriscreatedabovethecurrent layer,group,orobject.3. Doubleclickonthenewlycreatedlayerinthe“Layerpalette”toeditthenameofthelayer.4. “LayerOption”dialogboxwillappear.

5. Enter“LandUse”andhit“OK”andthelayernamewillappearinthelayerpalette

STEP - II. Placing the PDF:

1. Inthe“File”menuselect“Place..”2. A“Place”dialogboxwillappear.3. LocateandselectthePDFfileyoucreatedin TUTORIAL #B2, which contains the building footprintmapyoucreatedinTUTORIAL #B1.

4. ToembedthePDFfileintheIllustratorfile,deselectthe“Link”optioninthe“Place”dialogboxbya right click of the mouse. 5. Click“Place”.ThePDFfileisplacedintotheIllustratorfile.

STEP - III. Separating Individual Elements: (Ungroup Objects) Note: All the individual objects in the PDF file are grouped together as one object.

1. Clickontheselectiontool,andthenselecttheobject.(i.e.movetheselectiontoolsomewhereoverthe footprint map and click the left button of the mouse) 2. Inthe“Object”menuclickonUngroup.Theobjectswillbeseparated,howeversomeobjectsmightstill retain the compound paths. 3. Withoutdeselectingtheobject-fromthe“Object”menuselect“CompoundPaths”and“Release”.All theindividualobjectsinthefootprintmap,suchasblocks,curbs,willnowbeungrouped.

STEP - IV. Creating Rectangular Boxes for a Land Use Legend / Using the Align Palette:

1. Intheshapetoolbox,selecttherectangletoolbox().2. DecidewhereonthesheetthelegendwillgoandpositionthepointeratonecornerofthefirstLand Usecolorboxyouwanttocreate,anddragdiagonallyuntiltherectangleisthedesiredsize.3.

STEP - V. Adding Land Use color to the legend boxes:

1. Click on the selection tool. Select one of the rectangles. 2. Use the Pantone Solid Uncoated swatches 3. SelectanappropriatecolorforaparticularLandUseandhit“OK”.

�. Repeat steps 1-3 to assign different colors for different Land Uses. 5. WritethenamesofeachLandUsenexttothecolorboxes.ForaddingtextrefertoTUTORIAL # D1. 6.

B. Adding Color to Building Footprints:

Note: ForthistutorialafootprintdrawingcreatedinAutoCADwillberequired.APDFfileofthisAutoCADdrawing has to be made in order to bring the drawing an a known scale in Adobe Illustrator. TUTORIAL # B2 explainshowtocreateaPDFfilefromanAutoCADdrawing.

STEP -I. Opening a new drawing in Adobe Illustrator:

1. Open Adobe Illustrator. 2. Inthe“File”menuselect“Open”.

3. SelectthePDFfileyoucreatedinTUTORIAL # B2,whichcontainsthebuildingfootprintmapyou created in TUTORIAL # B1andclick“Open”.�. The footprint map will appear on the screen. 5.

A“rotate”dialogboxwillappear,enterthenecessaryanglefortherequiredorientationofthedrawing. • For this tutorial enter -90 and hit “OK”

The“Rotate”dialogbox



STEP -II. Creating and Switching Off Layers:

NOTE: The most effective way of ensuring that layers can be easily separated is to make them different colors in the original AutoCAD file. Then, when the file is imported, layers can be select-ed by color and copied into separate layers.

1. EnsurethatlayersinoriginalAutoCADfilearedifferentcolors.2. Importintothefile,followinginstructionsonthepreviouspage.3. CreatenewlayerstocopyyourAutoCADlayersinto.4.

STEP - III. Applying color: 1. UngrouptheobjectsasdiscussedinSectionBSTEPIII.2. Afteryouhaveungroupedtheobjectsinthefootprintmaptheywillstillbecombinedtogethervia “compoundpaths”.Torelease,againselectthefootprintmap,clicktherightbuttonofthemouseand clickon“releasecompoundpaths”.Thiswillseparateeachpolygonfromoneanotherwhichis helpfulifwehavetocoloreachofthemwithdifferentcolors.Howeverforthisexercisewewill color them with a single color.

3. Withoutdeselectingthebuildingfootprints,clickonthe“Fill”tool.Selectacolorfromtheswatches.

Double click on the Fillbox

Select black from the swatches

The selected color will appear on theFillbox

• Use black for this tutorial as it is useful to have the footprints as black and open spaces as white. More contrast will help in drawing clarity.



4. Click“OK”inthecolorpickerdialogboxafterselectingthecolor.Onthescreentheblocksnowbefilled withwillappearwiththefilloftheselectedcolor.

5. Clickwiththecursoranywhereonthescreenoutsidetheobjectarea.Thiswilldeselectthebuilding footprints.

• This tutorial can be done with following methods: 1. By “Placing” an EPS file created from AutoCAD into an new or existing Illustrator file. This is helpful while you working on a presentation board in Adobe Illustrator. 2. By “Opening” a PDF file in Adobe Illustrator. This is helpful when you want to edit the PDF. 3. By “Placing” an AutoCAD drawing into Adobe Illustrator. • The advantage of the first two methods is that the drawing can be inserted at a known scale, but when a drawing is placed directly from AutoCAD we have to manually scale the drawing in Adobe Illustrator .

this process the transparent areas can further be highlight-ed.

• For this tutorial select “Overlay”. Patterns or colors overlay the existing artwork while preserv-ing the highlights and shadows of the base color. The base color is not replaced but is mixed with the blend color to reflect the lightness or darkness of the original color.

• With these steps you will be able to highlight regular an irregular zones on an aerial image.
