3D toolbar view controls
Default View
Returns to a preset zoom, pan, rotation, and projection mode of the 3D model. You can use the
Options menu on the Model Tree or the Manage Views command on the 3D toolbar Views menu to set a different
view as the default.
If an object ever moves out of your view, you have, in essence, turned your camera completely away from the object.
Click the Default View icon on the 3D toolbar to move the object back into view.
Views menu
Lists any views defined for the current 3D model.
Toggle Model Tree
Opens and hides the Model Tree panel.
Play/Pause Animation
Plays or pauses any JavaScript-enabled animation.
Projection
Toggles between using perspective and orthographic projection of the 3D object.
Model Render Mode menu
Determines how the 3D shape appears. For an illustrated guide, see “Examples of Model
Rendering modes” on page 115.
Enable Extra Lighting menu
Lists the different lighting effects, in which the number, color, orientation, and
brightness of the lights, the reflectivity of the surface, and other factors affect the illumination of the 3D object.
Experiment with No Lights, White Lights, Day Lights, Bright Lights, Primary Color Lights, Night Lights, Blue Lights,
Red Lights, Cube Lights, CAD Optimized Lights, and Headlamp to get the visual effects you want.
Background Color swatch
Opens the color picker, which you can use to select a different color for the space
surrounding the 3D object.
Examples of Model Rendering modes
The Model Render Modes include combinations of factors that affect the appearance of the 3D object. The illus-
tration below shows a simple object rendered in each of the available modes.
Editing 3D models
Use a 3D authoring application to make changes to your 3D source images.
Change rendering mode, lighting, projection, and background
The model rendering mode determines the surface appearance of the 3D model. The default rendering mode is
usually solid, but you can also choose another rendering mode. You can also change the lighting of the 3D model as
well as the background.
❖
Use items on the 3D toolbar to make any of these changes:
•
To change the rendering style, choose an option from the Model Render Mode pop-up menu
.
•
To view an orthographic projection, click the Use Orthographic Projection button
. An
orthographic projection
effectively removes a dimension, preserving the size ratio between objects but giving the 3D model a less realistic
appearance. Click the button again to use perspective projection.
•
To turn lighting on or off or to change lighting, choose an option from the Enable Extra Lighting pop-up menu
.
•
To change the background color, click the arrow next to the Background Color swatch and choose a color.
Note:
Model Render Modes, Lighting Schemes, and Background Color options are also available by right-
clicking/Control-clicking the 3D model. Model Render Modes also appear under the Options menu on the Model Tree
panel.
