7. A glass

This exercise will show you that there may be several different ways to get the desired results with Amapi 3D. In this example, we will make a glass from the same curves with two different tools. First, we will use the Extrusion tool. Next, you will see that we can produce the same object using the Sweep tool!

Drawing the construction curves

Þ Step 1: The base

q Tool: Drawing tool, Circle q Do it: 1. Face view, then top view (keys 2 then 5). 2. Select the Circle tool. 3. Draw a circle and specify that it have 16 points. q See the detailed explanations in the chapter: User Manual/Tools/Drawing/Circle

Þ Step 2: The profile curve

q Tool: Drawing tool, Polyline q Do it: 1. Select the Polyline tool. 2. Draw the glass profile. Begin the first point by clicking a point of the circle. 3. Make sure the last point is vertically aligned with the center of the circle by using the constraints. q See the detailed explanations in the chapter: User Manual/Tools/Drawing/Polyline, User Manual/Tools/Assistant Palette/Cursor movement and positioning constraints

Þ Step 3: Round the angles

q Tool: Fillet q Open the model file: Gobelet1 q Do it: 1. Make sure the profile is the current object. 2. Select the Fillet tool. 3. Click twice on the right hand mouse button (or Command+click on Mac) to get the Bullseye. 4. Select the angle to be rounded. 5. Validate. 6. Set the fillet radii. 7. Validate. q See the detailed explanations in the chapter: User Manual/Tools/Modeling/Chamfer

Extruding the glass (2 methods)

Þ Step 1a: (1rst method)

q Tool: Extrusion q Open the model file: Gobelet2 q Do it: 1. Make sure the circle is the current object. 2. Select the Extrusion tool. 3. Click the profile. 4. Click on the red curve to close the glass bottom. The glass is complete. q See the detailed explanations in the chapter: User Manual/Tools/Construction/Extrusion

Þ Step 1b: (2nd method)

q Tool: Sweep q Open the model file: Gobelet2 q Do it: 1. Make sure the profile is the current object. 2. Select the Sweep tool. 3. Click on the circle. 4. Click on the red curve to close the glass bottom. The glass is done. q See the detailed explanations in the chapter: User Manual/Tools/Construction/Sweeping
