Displays iso-angle lines on surfaces. This lets you visually evaluate continuity across surface boundaries. You can also use this tool to create iso-angle curves-on-surface.
Iso Angle Control options
Controls whether iso-angle lines are white ( ) or colored ( ).
The width of white band iso-angle lines. This option is only available if is .
The number of times colored band iso-angle lines are repeated on each surface. This option is only available if is .
Controls whether iso-angle lines are displayed as shaded lines (checked) or not (unchecked).
Check this box to display iso-angle lines as curves-on-surface. Select the type of curves from the options below.
Controls whether curves-on-surface are created from iso-angle lines, or actual curves-on-surface. The latter can be used for modeling operations such as geometry creation, trimming, or measuring.
If is turned on (in Preferences > Performance Options
), curves-on-surface temporarily become visual curves during the interactive updates to provide faster redraw. This does not happen if the curves-on-surface have locators on them, are used in trimming, or if the transformation requires the tessellation to be recomputed (for example, in ).
When is selected as the , this value defines the quality of the visual curves independently of the tessellation tolerance. This lets you set the visual tolerance to a smaller value to get better quality visual curves, without reducing the tessellation tolerance used for shading.
The blurriness of iso-angle line edges. This option is only available if is on.
The position of the vector represented by the arrow icon (light source).
The transparency of surfaces with iso-angle lines.
Save the history of curves-on-surface for later editing. If you turn on, you can modify the surfaces and the curves-on-surface update.
