Customizing 3D Effects. Autodesk AUTOSKETCH 8

To skew an entity along an isometric plane

1 Click the 3D Effects button on the Standard toolbar. The 3D Effects toolbar appears.

2 Select an entity (or entities) to transform.

3 Click one of the Transform Isometric buttons on the 3D Effects toolbar:

■

Transform Top Isometric skews the entity along 30- and 150- degree axes.

Transform Left Isometric skews the entity along 90- and 150- degree axes.

Transform Right Isometric skews the entity along 90- and 30- degree axes.

4 Click an Isometric Origin point on the entity. This is the point from which the entity is skewed.

NOTE If the Use Default Isometric Origin check box is checked in the 3D

Effects Options dialog box, you need not click an origin for the entity after you click the appropriate Transform Isometric button.

Customizing 3D Effects

By default, AutoSketch uses the entity’ s properties to determine how an extrusion will appear. However, you can change the way AutoSketch applies parallel extrusion, perspective extrusion, or isometric effects using controls in the 3D Effects Options dialog box.

NOTE Changing settings in the 3D Effects Options dialog box only affects future 3D Effects operations. Changes do not affect the current selection set.

Changing Render Settings

The 3D Effects Options dialog box allows you to control the way AutoSketch renders extruded entities. Options in the Render section allow you to select the rendering mode as well as the type of entities used to connect the extrusion:

■

■

Selecting Wireframe rendering mode shows all connecting lines during an extrusion. This mode renders faster but looks less realistic.

Selecting Hidden Line rendering mode allows surfaces that face you to obscure lines behind them. This mode renders slower but looks more realistic.

Selecting As Lines causes AutoSketch to draw the extrusion as a group of individual lines, creating a more open appearance than As Polygons. This option can be useful if you plan to further edit the extrusion entity.

Selecting As Polygons causes AutoSketch to draw the extrusion as a group of polygons. This allows you to apply solid fill.

To change the way extrusion entities are rendered

1 Click the 3D Effects button on the Standard toolbar. The 3D Effects toolbar appears.

2 Click the 3D Effects Options button on the 3D Effects toolbar. The

3D Effects Options dialog box appears.

3 In the Render section, click either Wireframe or Hidden Line.

4 In the Render section, click either As Lines or As Polygons.

5 Click OK.
