Warning

SolidWorks reading has been moved from the library LibUgSwSeRead_MDNET20xx._xx.lib to LibSwReadWrite_MDNET20xx._xx.lib . This library depends on LibUgSwSeRead_MDNET20xx._xx.lib. The SolidWorks writing library has been renamed from LibSwWrite_MDNET20xx._xx.lib to LibSwReadWrite_MDNET20xx._xx.lib .

Utils

Added new possibilities in enum Dtk_PointType :
DTK_PT_SQUARE, // an unfilled square

DTK_PT_UP_TRIANGLE, // a triangle pointing up

DTK_PT_DIAMOND // a square rotated by 90 degrees
