| Display Options |
| Curves: Displays only the ISO curves in both shaded and wireframe viewports Mesh: Displays only the polygons for both shaded and wireframe viewports. Both: Will display mesh in shaded viewports and edges and iso-parametric curves in wireframe viewports. |
| Mesh Quality Presets |
| Coarse: Lowest quality mesh generation setting. This option will generate the fewest polygons. Medium: Medium quality mesh generation Fine: Highest quality mesh generation setting. This option will generate the largest number of polygons. Note: these default settings can be modified by editing the PowerSolids.ini file. |
| Mesh Display |
| Viewport Display Settings panel controls how the Power NURBS Brep Object is displayed in the viewport. These settings are also used when converting to an Editable Mesh/Poly to control how the polygons are created. Quads: Generate quad mesh (normally the mesh will be triangles). Use the "Max Edge Ratio%" to control the size of the generated quadrilaterals. Weld/Smooth: Smooths out polygons, removing tiny edges and polygons Face Approx Angle: Defines the maximum angle for a polygon face. Faces with an angle greater than this value will be sub-divided into multiple polygons. Decreasing this value will increase the quality of the image. Edge Approx Angle: Similar to the "Face Approx Angle", but defines the maximum angle for a polygon edge. By default (when this value is set to zero), it will use the same value as "Face Approx Angle". Face Distance %: The maximum absolute error between the mesh and the actual precise geometry. The percentage is based on the size of the object. Adjusting the distance % of the Face is the preferable way to increase the mesh quality without getting too many polygons. Edge Distance %: Similar to the "Face Distance %", but defines the maximum angle for a polygon edge. By default (when this value is set to zero), it will use the same value as "Face Distance %". Max Edge Ratio: Sets the maximum length for any mesh edge. Use this to get a mesh without those long skinny polygons. This value is used to control the Sub-D mesh generation. |
| Curve Display |
| Display Surface Knots: Displays Iso Curves at the NURBS knots on the faces. Lines U: Defines the number of crosshatch curves for ISO curve display (number of sub-divisions in U direction) Lines V: Defines the number of crosshatch curves for ISO curve display (number of sub-divisions in V direction) Iso Line Angle Tol: Defines the angle tolerance to use in the display of iso-parametric curves. Iso Chord Height: Defines the chord height used to display iso-parametric curves |
| Mesh Updates |
| The following options are used to reduce the memory footprint of your model. If you are dealing with large amounts of data, and your performance is lagging, these options might help. You can temporarily remove this information. When you perform commands that require this information, it will re-calculate the necessary information (which will take longer). Purge R Mesh: This option will remove the render mesh data. When you go to do rendering, it will need to re-compute the render mesh (if you choose this option). Purge V Mesh: This option removes extra viewport mesh information. It will retain the viewport mesh data for the top level objects, but will remove the sub-object viewport mesh data. When you edit the sub-objects, it will have to re-generate the viewport mesh in order to display the sub-objects. Clean Children: This option will clean out additional BREP data that we keep with the sub-objects. |
