Translates NURBS into the SLC format to create a valid solid watertight model for Solid Imaging.

Output Units

Indicates in which units you want to output the SLC data. This choice (millimeters or inches) will be reflected in the output .slc file’s header’s keyword “-UNIT”. By default the value will be inches.

Model Type

Specifies the StereoLithography model type.

• Part or Support – Must be closed contours (polylines). By default, the model type is Part.
• Web type – Can be open polylines or line segments. Typically used to support cantilever regions on parts.

The choice will be reflected in the output .slc file’s header’s keyword “TYPE”.

Auto Range

If toggled ON (default) this option uses the bounding box of the object to determine where to compute the slices (contour data). The slices will be produced for the entire object, no matter what its position is in space, If toggled OFF, two extra sliders are displayed.

Thickness

Specifies the spacing (in mm) of the slices (contoured layers). By default the value is 0.01 mm.

The Header Section

The header section of the .slc file is an ASCII character string (up to 2048 bytes) containing global information about the model.

The output in the header provides the following information:

• SLC file format version number (-SLCVER2.0)
• Output units (-UNITS<INCH/MM>
• Type of model (-TYPE<PART/SUPPORT/WEB>)
• Vender package and version number (which produce the SLC file (-PACKAGE ALIAS STUDIO V10.0)
• Calculations and sets from SLC output x,y,z extends of the model (-EXTENTS mx,Mx,my,My, mz,Mz)
• Header keywords (CHORDDEV, ARCRES, SURFTOL, GAPTOL, MAXGAPFOUNS, EXTLWC, STHICK, STARD and ENDD) are set to 0.0.
