• 环境光遮蔽 - 控制环境光遮蔽阴影的强度，范围从 0% 到 100%（默认值：37.5%）。数值越高，边缘、角落、缝隙以及零件接触或相交处会产生柔和的暗部阴影。这有助于模拟这些位置在真实世界中的间接光照效果。数值越低，这些位置的阴影越少。

  

  环境光遮蔽：0%

  

  环境光遮蔽：100%

• 视野（仅在启用透视视图时可用） - 控制透视相机的视野。使用水平滑块或输入 20-120 度的数字。

  

  视野：20 度

  

  视野：100 度

Shaded bodies

• 线宽 - 控制曲面和边的线宽。使用水平滑块或输入 0.1-3 像素之间的数字。

  

  线宽：0.5 像素

  

  线宽：3 像素

• 光泽度 - 控制着色曲面的默认光泽度。使用水平滑块或输入 1-100% 的数字。

  

  光泽度：1%

  

  光泽度：100%

• Specular color - Controls the default specular color of shaded surfaces. Click the color swatch to open the Color picker dialog and select a color.

Phantom Edges

• 影线相切边宽度 - 如果“相切边”设置为“影线”，此选项控制这些边的线宽，范围为 0.1 - 3 像素（默认值：0.5 像素）。

  

  影线相切边宽度：0.5 像素（左）；3 像素（右）

• Phantom tangent edge color - If Tangent edges are set to phantom, this controls the default color of those edges. Click the color swatch to open the Color picker dialog and select a color.

  

Mesh bodies

• 网格线宽 - 控制网格曲面和边的线宽，范围为 0.1-3 像素（默认：0.3 像素）。

  

  网格线宽：0.3 像素（左）；2.5 像素（右）

Active sketches

• Line width - Controls the line width of active sketches. Use the horizontal slider or enter a numerical input from 0.1 - 3 pixels.

• Constrained line color - Controls the default color of constrained lines or points. Click the color swatch to open the Color picker dialog and select a color.

• Underconstrained line color - Controls the default color of underconstrained lines and points. Click the color swatch to open the Color picker dialog and select a color.

• Underconstrained show-through line color - Controls the default color of underconstrained show-through lines and points. These are lines and points that are obscured by parts in the graphics area. Click the color swatch to open the Color picker dialog and select a color.

Inactive sketches

• Line width - Controls the line width of inactive sketches. Use the horizontal slider or enter a numerical input from 0.1 - 3 pixels.

  

• Line color - Controls the default color of lines and points of inactive sketches. Click the color swatch to open the Line color dialog to select a color from the Color picker.

  

Construction lines

• First dash - Controls the length of the first dash in the construction line stipple pattern. Enter a value from 1-50 pixels (default is 4 px.).

• First gap - Controls the length of the first gap in the construction line stipple pattern. Enter a value from 0-50 pixels (default is 6 px.).

• Second dash - Controls the length of the seond dash in the construction line stipple pattern. Enter a value from 1-50 pixels (default is 30 px.).

• Second gap - Controls the length, in pixels, of the second gap in the construction line stipple pattern. Enter a value from 0-50 pixels (default is 6 px.).
