Drawing Challenge

1. Create a new drawing. Select File>New Drawing:
   
2. Select the acad.dwt template file and press the Open button to continue to the drawing screen.
   
3. Type UN and select UN (UNITS):
   
   
   or press Format>Units to bring up the Units Dialog box. Set your units to millimeters.
   
4. Draw the white shape using the dimensions provided (Green layer). You will have to use a combination of relative and polar coordinate input:
   
5. If you make an error along the way, remember that you can use your ENDPOINT Osnap to begin where you left off.
6. Save your drawing.

Dimensioning and Layers

Without dimensions you can't communicate the size of your objects. Is it a real house or a doll house? Layers are used to organize your drawings.

You will be creating two layers. One for the Object (lines that were drawn) and another for the dimensions.

1. Start the LAYER command (LA) or press Command+4
   
   
   This will bring up the Layer Properties Manager Palette:
   
2. Click the New Layer Button.
   
3. Name the new layer object.
4. Open the Properties Inspector.
   
5. In the Properties Inspector make the layer's color color white:
   
6. Create another layer and call this one dims (for dimensions), and make its color green.
   
7. Select all your objects (Command A) or drag a box around all of them and then look for the Layer Properties Manager Palette. There is a drop-list there with your layer names. With your objects selected, change the layer to object.
   
   
   If all went well, your lines will now be on the object layer.
   
8. Bring up the Layer dialog box and make dims your current layer.
9. There is a Dimension Menu. Here are your options:
   • Linear dimensions are used for dimensioning either horizontal or vertical lines.
   • Aligned dimensions will measure the actual length of an angled line.
   • Radius dimensions will give you the radius of either arcs or circles.
   • Diameter dimensions are used on circles.
   • Angular dimensions will measure the angle between two lines that you pick.
   • Baseline dimensions are a special type that will automatically stack dimensions along one plane as you pick points.
10. Turn your OSNAPS on to endpoint only.
11. The type of dimension you pick will depend entirely upon what information you want to convey to the person reading the drawing. We'll start with the most common (and easiest): Linear Dimensions., You can select this from the menu or type DIMLINEAR. You'll use this type to add dimensions to all your horizontal or vertical lines.
    
    Press RETURN to select a particular line.
12. Click on the endpoints of a line segment and move the numbers away from the drawing.
    
13. Dimension the first angle. Type DIMANG:
    Click on the two lines and place the angle in a place that makes sense:
    
14. Now you want to dimension the segment. Type DIMALI and click on both endpoints:
    
15. Continue to dimension the drawing.
16. Save your drawing as drawing_challenge_1.

Drawing Challenge 2

You will draw a new shape that takes advantage of Relative and Polar Coordinates. Add layers for your object and your dimensions. Dimension the drawing. Exchange drawings with a classmate. They should be able to use your dimensions to accurately recreate your drawing.

1. Create a new drawing. Select File>New Drawing:
   
2. Select the acad.dwt template file and press the Open button to continue to the drawing screen.
   
3. Type UN and select UN (UNITS):
   
   
   or press Format>Units to bring up the Units Dialog box. Set your units to mm.
   
4. Create layers for your object and its dimensions.
5. Draw your shape on the object layer.
6. Dimension your object on the dimensions layer
7. Save your drawing.
8. Take a screenshot of your drawing (On a MAC the screenshot is Command_SHIFT+4 and then drag a box around what you want to capture).
9. Exchange screenshots
10. Recreate your classmate's drawing, include layers and dimensions.
