Figure 168. Networks Save and Load

To save all network objects (i.e. points, curves and patches) to a SLICE file, use the Save button towards to the top the Networks window (see Figure 168). The saved network can then be loaded back in at a future date with the Load button.

Note: points, curves and patches being loaded are added to any existing network. If you wish to end up with only the objects in the selected SLICE file, click on Reset before loading.

Also Note: When a network is first loaded you need to click on Rebuild to recreate the surfaces.

Exporting NURBS Surfaces

NURBS patches can be exported into an IGES file as entity type 128. Each entity is named with the patch name, and you will be warned if there is any truncation; IGES entity names are limited to 8 characters.

Only the geometry and name of each patch is exported; all texture map information and the future ability to change the shape of the surface within CySlice is lost when a NURBS network is exported to an IGES file.

Figure 169. NURB Surface Export

The size and orientation of the exported surface can be set by adjusting the Scale and Rot fields of the Save Options window (see Figure 169). You can either type in your own values, or use the common unit and axis values accessible to the right of each field.

Exporting SUBD/Poly Surfaces

SUBD and Poly surfaces can be exported into either PLY or OBJ files. Only the geometry and UV coordinates of the surface are exported; all other texture map information is lost, and the future ability to change the shape of the surface within CySlice is limited when a SUBD/Poly network is exported to an PLY/OBJ file.

Figure 170. SUBD/Poly Surface Export

The size and orientation of the exported surface can be set (see Figure 170), and for SUBD surfaces you are also be given a choice of Level 0, 1 or 2. Level 0 is the control hull, and is normally all you need to save. The others are the surface at 1 and 2 levels of subdivision, and might be handy for some applications.
