Viewing Models
| <<< Handling Files | Chapters | Editing Models >>> |
This chapter describes the different ways that you can change the way a model is viewed in PS/Workshop. It describes how you can alter the direction and scale with which a model is viewed, and how you can alter the appearance of the model itself by using different types of view.
PS/Workshop offers a wide variety of tools to alter the direction from which a model is viewed, or the size of the image. Many of these tools are available directly from the toolbar.
The following tools are available to alter the position that a model is viewed from:
The following tools let you alter the size of the image in PS/Workshop:

Note: When 
is selected, you cannot select any entities in the document. See Section 4.2, "Selecting entities", for information about selecting entities. |
A number of standard views are provided as menu commands in PS/Workshop. By choosing the relevant command in the View > Standard Views submenu, you can switch instantly between the following view directions:
You can use the commands in the View > LineWidth submenu to change the width of lines used to display edges in a model. Choose any value from 1 (the default) to 5.
PS/Workshop provides a number of different ways of rendering a model on the screen. These are illustrated in Figure 3-2. If a part has a color attribute attached, then that color is used in the rendered image. Otherwise, the default body color, as specified in the PS/Workshop Options dialog, is used.
These colors, together with the document's background color, can be edited as described in Section 4.3, "Editing colors". Any model colors set within PS/Workshop are saved back as attributes to the model.
The following modes are provided in PS/Workshop:

Figure 3-2 Wireframe, wireframe + silhouettes, hidden line, and shaded modes
Zooming in on a portion of the model can produce a coarse screen image, especially if the model in the viewing area is curved. Click 
to recompute a smooth view for the current view parameters.

or choose
View > Modify > Rotate. Click and hold down the mouse button and move the mouse to rotate the model. All view modes, Wireframe, Wireframe plus silhouettes, Hidden Line and Shaded, are supported. View dependent silhouette calculation is suspended while the view is changing. It is recomputed when the mouse button is released.
or choose
View > Modify > Rotate. Click and hold down the mouse button and move the mouse to pan the model. 
or choose
View > Modify > Zoom. To zoom in (make the image larger), click and hold the mouse button while moving the mouse up. To zoom out (make the image smaller), click and hold the mouse button while moving the mouse down. 
or choose
View > Modify > Zoom to Fit. Select this icon to change the scale factor of the view so that the model fills the window in which it is displayed. 
.Define the area of the document you want to view by clicking and holding down the mouse button in the top left corner and dragging the mouse to the bottom right corner. This zooms the display such that the area of the selected rectangle fills the window.
or choose
View > Display > Wireframe to display the document in wireframe mode. This mode renders every edge on the model on the screen. 
or choose
View > Display > Wireframe + Silhouettes to display the document in wireframe silhouette mode. Silhouette edges are edges that are implied by the view, rather than being real edges in the model itself. Their locations depend upon the view parameters and are computed as the view changes. 
or choose
View > Display > Hiddenline to display the document in hidden line mode. This mode shows only those parts of real and silhouette edges that can be seen from the current view direction. Any part of an edge that is obscured by some other part of the model is not drawn. The results depend upon the view parameters and are computed as the view changes. 
or choose
View > Display > Shaded to display the current model in shaded mode, as shown in
