FileIgsWriteOptions Properties

TRUE means all periodic NURBS will have their end knots clamped.

d >= 3 means all NURBS curves with degree > d be fit with degree d non-rational cubics.

Use "E" instead of the correct "D" for double scientific notation to get around IGES bug in FastShip.

IGES files are ASCII files. You need to specify the flavor of the ASCII end of line marker.Possibilities are: TL_LF: line feed (unix) TL_CRLF: carriage return, line feed (Microsoft) TL_CR: carriage return (Apple)

true means all rational NURBS will be fit with non-rational cubics.

true means non-conic rational surfaces will be fit with non-rational surfaces

true means all NURBS surfaces will have their internal knots set to full multiplicity.

true means all surfaces will be exported as 143 or 144s CATIA may like this better.

Version of IGES spec to write

The GridTool program used at NASA Langly cannot read IGES files that have leading zeros in the T section.

(model space units)/(real world units) For example, if unit_system = TL_INCHES and 1 model space unit = 8 inches, then scale = 0.125.Note that model space units are stored in the IGES file.

TRUE means NURBS that are lines or arcs will be written as lines or arcs instead of 126's

true means that NURBS surfaces that are ruled surfaces or surfaces of revolution will be written as ruled surfaces or surfaces of revolution.

In model space units specified above

copy parent label to dependent curves

copy parent label to dependent srfs

true means the UnitNormal will be written regardless, even if the curve is non planar
