Day 0ne Objectives: Learn how to use Basic Draw commands Line, Rectangle, Circle and Arc. Learn how to use Edit commands Move, Push/Pull, Move/Copy and Offset. Learn how to use Camera commands Zoom, Orbit and Pan. How to create components and place them.

Today’s exercise you are going to be drawing a castle. First open the program. You will find the program located under “All Programs” when you click the Start Menu Select the architectural feet an inches template. Save the file the following way “6*”last name”3Q (*is your day A or B) into your documents file. Example “6B3QSmithson”

Now to start drawing: Select the woman and delete Select the Rectangle Icon Starting at the Origin point Drag the corner of the Rectangle out to the right & set it. Now type 40’, 70’ in the little box in the bottom right hand corner with the label “Dimensions” and press Enter The dimension input box is located on the bottom ribbon of SketchUp. You do not need to place your cursor there before typing. You can use different methods of entering distances. Inches are the default measurement in Sketchup. For that reason, if you type 36, you will get a distance of 36 inches. When writing distances, the apostrophe represents feet and quotation marks represent inches. If you wanted to enter a distance of 36 feet and 7 inches, you would type 36’ 7” . If you are making a rectangle, you will need to use an ordered pair of numbers, where the first number is the size of the base (Red axis) and the second is the height (Green axis). A rectangle with a base of 12’ 0” and a height of 6’ 6” would be entered 12’, 6’ 6” .

The Orbit, Pan and Zoom commands These commands can also be accessed in the Camera menu. Make sure to set the drawing back to where the solid blue line is facing up and to the left of the screen. Use the Zoom Extents for this These commands are somewhat easier with a mouse, especially one with a scroll wheel. Both the Orbit and Zoom commands can be executed without having to click on their icons or typing anything on the keyboard. To Orbit, press the mouse’s scroll wheel like a button and moving the mouse around. To Zoom with a mouse: place the cursor and left-click on the point you want to zoom in on, then roll in or out with the scroll wheel. To Pan, click on the hand icon or type H or h, press the left mouse button, then drag across the screen.

Drawing Circles Click on the Circle Command Set the Center for the circle away from your rectangle Make sure there is a Blue circle at your cursor and drag out from the center Circles are not really circles in SketchUp. They are polygons with many sides. The default is 24 sides. The number of sides is the first prompt you will see when you click on the Circle Tool. Consequently, when you draw a large circle, you may notice that it does not have very smooth edges. If this is a problem for you, change the number of sides to a larger number, like 100, or 200. The Sides prompt will happen after you select the Circle Tool, but before you click on a center point. When you execute your circle, you will need to Click and Drag: First, Click to establish the center point of the circle; then Drag to establish the orientation of the circle. The radius will be established where you release the mouse button. You can alternatively change the radius by entering a specific radius in the Dimension box.

Drawing 10’ Tower Bases Use the four corners as center points for Circles. Enter a radius of 5’ (or 60 inches) in the dimension box. Make sure they are centered on the corners.

Cleaning up extra lines Click on the Erase icon Remove the corners of the rectangle and the extra lines inside of the Rectangle. Repeat this in all four corners

Using the Offset command This function creates offset parallel lines around the selected shape that are spaced according to the distance you choose. Use the Select tool to click on the Rectangle with the corner circles. (make sure the extra lines have been edited) The outside lines and the arcs in the corners should turn Blue.

Using the Offset command With the Rectangle and arcs selected (all the lines should be Blue) Click on the Offset Icon and pull the cursor outside of the frame. Set this Distance to 18” or 1’ 6” in the measurement box Hit Enter.

Push/Pull the Walls This function creates an extrusion of a profile Select the outer ring then access the Push/Pull icon Pull the walls up & enter 25’ in the Dimension box 25’ Before you apply this command, you need to make sure that the wall perimeter is a closed set of lines. If it is not, you need to make everything right before you proceed. You may need to go back a step and re-do the offset operation. You will be able to tell you did everything correctly if the entire outside edge highlights when you select it with the Push/Pull tool.

You now have walls for your Castle Use the Orbit command and zoom around your castle

Learning how to use the Component Command Components allows complex objects to be moved around the drawing easier. Components can be given attributes, this allows them to inventoried in a drawing In this case we are going to create blocks for the top of the castle wall Save them as a component , then place them where they need to be

Creating a component First you must draw an object, in this case you are going to draw a block. Draw a rectangle that is 18” by 48” Using the Push/Pull command make the Rectangle 24” tall Triple-Click on the block to select the entire shape

Creating a component With the block selected Go to Edit > Make Component Give the component the name Wall Block Click on Create

Moving a component When you select the block, the entire object is grouped. This makes it easier to Move/Copy and Rotate In the next steps, you are going to place the component on the top of the wall Then perform an array copy that spreads the blocks down the wall Then do a rotational copy to do the other walls

Moving a component Moving a component is similar to moving an object except how it is grabbed A component has limited handle points. You will almost always use the object’s corners

Moving a Copy of a component Click on the Move Tool Grab the component from the bottom right corner Hold the Ctrl key and drag it to the top of the wall By grabbing back corner it is easier to place it on another vertices

Making Multiple copies Huge advantage of CAD is the ability automate redundant tasks this case drawing the same object 40 times This called an Array copy

Making Multiple copies Select the Move tool select the block on one of its corners Hold the Ctrl key and Drag the block to the end of the wall

Making Multiple copies After setting the block type /9 in the measurement section This makes 9 evenly spaced copies Try some different numbers to see what it looks like

Making Multiple copies You can also Move/Copy multiple items at once, In this case copy the blocks from one side to the other Using Select tool hold down the shift key to make multiple selections

Making Multiple copies Select the outer bottom corner Hold the Ctrl key and Drag the blocks to the opposite wall

Rotating an Object Now to place blocks on the other walls you have to rotate that first block you made If you forgot to make a copy of that block, that is not a problem just make a copy of one of the blocks on the wall Rotation command is similar to the Move command, but changes an objects orientation

Rotating an Object Select the object to be rotated Go to Tools > Rotate A protractor will appear over the object Place the center of the protractor on a convenient corner

Rotating an Object The next step is to create a starting line for rotating the object Then rotate the object to the desired angle on the protractor

On your Own ! Copy the blocks just like you did in previous steps Use the Move/Copy to create a new array Your castle needs a door A ledge for your archers Steps to get to the ledge How about some Color

On your Own ! Making a castle door can be done a few ways This a way it could be done First draw the profile of the door on wall & pull it out 6” Rotate copy the front door on to the ground And pull it up 6” Look at sequence in next slide

Making Steps ! Create a component with the dimensions 12” high,48” long 15” deep) Copy component by grabbing lower left corner & moving to that’s component’s upper right corner Type *9 return, that will create nine copies of the component

Making a Turret Draw a circle with a Radius of 5” Draw a vertical Rectangle on the circle (use hovering technique) Bisect rectangle into two triangles Get rid of extra lines Access follow me command Follow sequence in next slides

Making a Turret

Making a Turret In the tools menu access the follow me tool

Making a Turret Select the triangle & map it around the circle it should create a cone. Make sure the triangle is vertical

Making a Turret

Moving the Turret First make the Turret a component Next center a turret on top of each cylinder (use the move/ copy command) Add a walk way Add landscape features Add some color

Radial Copy Objects  Creating multiple rotated copies (radial arrays)The Rotate tool can also be used to create radial arrays, or a series of copies around a rotate point. To create a radial array. Select the Rotate tool (). The cursor will change to a protractor with a circular arrow. Click on the entity to rotate. Press and release the Ctrl (Microsoft Windows) or Option (Mac OS X) key on your keyboard. The cursor will change to a protractor with a plus sign. This action informs Sketchup that you want to duplicate the entity. Move the cursor in a circle until it is at the starting point of the rotation. Click to set the starting point of the rotation. Use the inference tool tips to help you to find the center of the rotation. Move the cursor until it as at the ending point of the rotation. A copy of the entity appears and is rotated about the starting point. If the 'Enable angle snapping' checkbox is checked in the Units Panel of the Model Info dialog box, movements close to the protractor result in angle snaps, while those further away from the protractor allow free rotation. Click to complete the rotation. Type a multiplier value to create additional multiple copies. For example, typing in 2x (or *2) will create one additional copy (or 2 copies total, the one you manually copied plus one you automatically copied using this step) instead of just one. Note: Press and hold the Ctrl (Microsoft Windows) or Option (Mac OS X) key at any time during a rotate operation to perform a copy (not just at the start). Creating copies at an equal distance apart You can divide the distance between the copy and the original by typing in a divisor value in the Measurements Toolbar. For example, typing 5/ (or /5) will create five copies evenly distributed between the original and the first copy. You can enter distances and multipliers until you perform another operation.

Moving an object Move/Copy are nested commands You are going to copy the circle to each corner of the rectangle. First window select the circle turning it Blue Now select the Move command
