ChangeXSecShape()

void ChangeXSecShape	(	const string &in	xsec_surf_id,
		int	xsec_index,
		int	type
	)

Change the shape of a particular XSec, identified by an XSecSurf ID and XSec index

// Add Stack
string sid = AddGeom( "STACK", "" );
 
// Get First (and Only) XSec Surf
string xsec_surf = GetXSecSurf( sid, 0 );
 
// Set XSec 1 & 2 to Edit Curve type
ChangeXSecShape( xsec_surf, 1, XS_EDIT_CURVE );
ChangeXSecShape( xsec_surf, 2, XS_EDIT_CURVE );

GetNumXSec()

int GetNumXSec

(

const string &in

xsec_surf_id

)

Get number of XSecs in an XSecSurf

// Add Stack
string sid = AddGeom( "STACK", "" );

string xsec_surf = GetXSecSurf( sid, 0 );
 
// Flatten ends
int num_xsecs = GetNumXSec( xsec_surf );
 
for ( int i = 0 ; i < num_xsecs ; i++ )
{
    string xsec = GetXSec( xsec_surf, i );
 
    SetXSecTanAngles( xsec, XSEC_BOTH_SIDES, 0 );       // Set Tangent Angles At Cross Section
