Amapi3D 5.0 Documentation

4. A champagne cap

Once again this is a very simple model, and again you will use the basic steps commonly used to create models with Amapi 3D:
1. Build the construction lines, meshes or basic volumes. Here a sphere will be used for the head of the cap and a circle for the body.
2. Model by modifying the construction shapes. Here we will cut and squash the sphere to make the head of the cap.
3. Assemble the parts to make the final scene. Here we will assemble the head and the body.

The cap’s head

· Step 1: Make a sphere

q Tool: Sphere
q Do this:
Create a sphere.
q See the detailed explanations in the chapter:
User Manual/Tools/Construction/3D Primitives/Sphere

· Step 2: Make a half sphere

q Tool: Delete Facet
q Do this:
1. With the Delete Facet tool and the Lasso (PC: Click the right button/Mac: Command+click), select the lower half of the sphere.
2. Validate. It is removed.
q See the detailed explanations in the chapter:
User Manual/Tools/Modeling/Delete

· Step 3: Squash the half sphere

q Tool: Scale
q Do this:
Take the Scale tool and squash the half sphere slightly, as shown.
q See the detailed explanations in the chapter:
User Manual/Tools/Assembly/Scale

· Step 4: Mirror the half head

q Tool: Symmetry
q Do this:
Mirror the half sphere under itself.
q See the detailed explanations in the chapter:
User Manual/Tools/Assembly/Symmetry

· Step 5: Weld the two half heads

q Tool: Weld
q Do this:
Weld the two parts of the head together.
q See the detailed explanations in the chapter:
User Manual/Tools/Assembly/Welding

· Step 6: Prepare the beginning of the body

q Tool: Delete Facet
q Do this:
1. With the Delete Facet tool and the Lasso (PC: Click the right button/Mac: Command+click), select the lower row of facets.
2. Validate. They are removed.

The cap’s body

· Step 1: The cap’s body

q Tool: Curve Extract
q Open the model file: 3Dline1
q Do this:
Select the Curve Extract tool and validate. A circle is automatically created.
q See the detailed explanations in the chapter:
User Manual/Tools/Construction/Extract Curve

· Step 2: The cap’s body (continued)

q Tool: Extrusion
q Do this:
With the Extrusion tool, build the body and close the bottom.
q See the detailed explanations in the chapter:
User Manual/Tools/Construction/Extrusion

Head and body assembly

q Tool: Weld
q Do this:
Weld together the head and the body. The result is a champagne cap!
For the finishing touch, apply a nice texture.
q See the detailed explanations in the chapter:
User Manual/Tools/Assembly/Welding

Smoothing the cap

q Tool: Smooth (partial smoothing)
q Open the model file: 3Dline2
q Do this:
1. To avoid undesired deformations on the body, select only the upper portion of the cap.
2. Apply a smoothing with a value 3.
