Drawing views with shading and/or drawn with as bitmap images

You can display the drawing view either in the form of geometry or a realistic shaded view.

To select the way in which the drawing view is displayed, select one of the options from the View mode area of the Drawing View - Visibility category of the Edit Properties dialog box.

Geometry only	In this mode, the view has no shading and is drawn as a set of curves.
Geometry and Image	In this mode, shading is added to the view using a bitmap image as background. Since the geometry is still present, the view is fully associative — it is possible to add dimensions and geometry. You are enabled to customize the image resolution, rendering modes, and effect parameters using the Image category under the Drawing View - Visibility category.
Image only	In this mode, the drawing view is represented as a bitmap image captured from the 3D model. The views created in this mode are much faster to regenerate, but the 3D geometry represented in the drawing as image is not pickable. Also, it is not possible to add dimensions and geometry. You are enabled to do the similar customization of the image as done in Geometry and Image mode. Additionally you can also choose the "edge" types to be displayed in the view. In this mode a rectangular boundary is added to allow the user to pick the view. While printing the view, the boundary is automatically made hidden.

In addition to adding shading to drawing views, it is also possible to create views as bitmap images by using the Image only mode. In this mode you can create not only a shaded view, but also a view with hidden edges or wireframe without shading.

A set of appropriate options is available in the Image area of the Drawing View - Visibility category of the Entity Properties.

• In the Resolution level drop-down list you can choose five different resolution levels for the captured image. The maximum achievable resolution value depends on the available video RAM of the video card.



• In the Value text box you can key in the resolution value for the captured image. The resolution value specifies the number of pixels of the longest edge of the image. If the resolution level is not set to Custom, the resolution value field is grayed because it depends on the level setting.
  If the Custom resolution level is selected, the value is editable and any value between 64 and 4096 could be specified.




Resolution level	Low	Medium	High	Very high	Custom
Resolution value (pixels)	512	1024	2048	4096	Any value between 64 and 4096



• In the Edges drop-down list you can choose the display modality for edges and silhouettes in the captured image ( Image only mode).



None	Enables the view to display shading without any edges. Enable shading is forcedly checked and grayed.
Visible	Enables the view to show only visible edges (only for Image only mode)
Visible + hidden	Enables the view to show visible edges (continuous line) and hidden edges (dashed line) — (only for Image only mode).
Wireframe	Enables the view to show all edges with continuous line (only for Image only mode; and no shading permitted.)

• The Enable shading check box enables you to turn the shading on and off alternatively:
  
  
  
  
  • When the check box is selected, the captured image is displayed with shading.
  • When the check box is not selected shading is not permitted in the captured image.


• The Enable high quality rendering mode check box enables you to control the high quality rendering to be applied.
  If Enable shading is selected Enable high quality rendering mode can be activated.
  (Only for the Wireframe edge type, high quality render is not allowed).
  
  
  
  
  • When the check box is selected, the model can be displayed in high quality rendering.
  • When the check box is not selected, the model cannot be displayed in high quality rendering.


• The Show model background check box enables you to control the display of model background.
  
  
  
  
  • When the check box is selected, an image can be set as the background of the model.
    (Note that it should be set to high quality render mode).
  • When the check box is not selected, the drawing displays a white color background (which is best for printing).


• The Brightness check box enables you to control the brightness level of the captured image using the slider you can determine the brightness.
  
  
  
  
• The Contrast check box enables you to control the contrast level of the captured image using the slider you can determine the contrast.
  
  
  
  


• The Show in grayscale check box enables you to control the display of image in grayscale.
  
  
  
  
  • When the check box is selected, the resulting image is displayed grayscale.
  • When the check box is not selected, grayscale display feature is disabled.


• The Reverse colors check box enables you to control the display of image in reverse colors.
  
  
  
  
  • When the check box is selected, the colors of the captured image are reversed.
  • When the check box is not selected, reverse colors display feature is disabled.
