Let's start by selecting a polygon sphere from the construction palette. Click and drag in the workspace to get the size of sphere you want. |
|
|
|
 |
|
After releasing the mouse button, the tuner icon appears. Adjust the number of faces on the sphere by hitting either the "+" or "-" key on the numerical keypad until the number "7" appears in the Data window (lower left side of workspace). You can also use the "+" or "-" keys on the Assistant palette will explain later why I choose 7 as the number. Hit the Return key or roll the cursor off the screen to the right to validate the sphere. |
|
|
|
 |
|
Now go to the top view by selecting the number "5" on the keypad. The numbers 2, 4, 6, and 8 are the front, back, left, and right views.
Select the Rotate tool in the assembly palette. |
|
|
|
 |
|
Using the "-" key on the numerical keypad or the "-" icon on the Assistant palette, reduce the number of spokes to 8. Click on one of the spokes and rotate the sphere to the next spoke. This will symmetrically position the polygons that will make the face. Validate the action by hitting Return or rolling the mouse off the screen to the right.
Click the number 2, 4, 6, or 8 to see the side of the sphere. |

Here is an isometric view.
Polygon 1 is where the left eye will be.
Polygon 2 is where the nose will be.
Polygon 3 is where the right eye will be.
Polygon 4 is where the upper lip will be.
Polygon 5 is where the lower lip will be. |

Hold down the mouse button and click the Option key. You now have access to the Lasso tool. Click again and you get a cursor for precise selection of points. Click these points with the cursor. If you use the Lasso tool you also select the points on the polygon on the opposite side of the sphere. We only want this side.
Select the Scale tool in the Assembly palette and you will see a red horizontal line and a green vertical line that intersect. Hit the spacebar once. This removes the red vertical line. Hitting the spacebar again will produce the green and hitting a third time will bring both. With the red horizontal selected, click and drag to the left to shrink the distance horizontally. Dragging right increases it. |

|
After validating the action, deselect the top points with the cursor tool and select the Stretch tool in the Modeling palette. Drag the points down to increase the height of the polygon by about one/third. Don't forget to hit the spacebar to get the red line to restrict the movement to vertical.

Click the left arrow a few times to rotate the view. Select the Extrusion tool in the construction palette and pull the nose out away from the face.
Validate. |
|
|
|
 |
|
Use the Lasso tool to select the two points at the top of the nose. In the modeling palette, select the Stretch tool and move the points down and closer to the face.

Roll the mouse over the Decimate tool in the modeling palette. The Tessellate tool appears to the left. Click on it and four options appear. Select the far left option. Click on the front of the nose and the polygons on either side of the nose.
Validate. |
|
|
|
 |
|
Select the Delete tool in the modeling palette. Again four options appear. The far left option will delete facets. Select it and delete the polygons that reside on either side of the nose. These are the ones we assigned as eyes.
Validate. |

Go to the construction palette and roll over the Facet Extraction tool. The Draw A Polygon tool appears to the left. Click it. Zoom in to the work area by clicking the "3" key a few times. Place the cursor over the area where the bottom of the nose joins the ex-eye polygon. Hold down the Shift key and the cursor is drawn to the point as a magnet. Click and move the cursor along the points shown here. Hit shift and click at each point. This can be a tricky exercise. Be sure to rotate the view and inspect from several angles. Once you're satisfied, hit Return. Repeat this step on the other side of the nose.

Go to the assembly palette and select the Weld tool. Draw a lasso around any part of the head and the two new polygons.
Validate. Now the three pieces are joined. |
|
|
|
 |
|
From the menu go to Tools, Advanced Tools, Close an object. Click on the hollow areas highlighted in red. The holes are now filled. |
|
|
|
 |
|
Select the Delete icon in the modeling palette, choose the Edges option and delete the vertical edges on the front of the nose. The funky black blobs show us we have points we don't need. By taking the wand and hitting the Option key to get the lasso, select the area of the nose. Now we see the points in question. Select the third delete option and click on the points. Now things should look right.
