sur_conarr - Geometric procedure

Creates a surface


Description

Creates a conic lofting surface. It is the same function as sur_conic() except that the input data is given in arrays.

Syntax

sur_conarr(id, ncur, spine, lim, tan, m, mcur:attributes);

REF	id;
INT	ncur;
REF	spine;
REF	lim ( );
REF	tan ( );
STRING	m ( );
REF	mcur ( );

Principal parameters

id	- Local identity
spine	- Spine curve
lim	- Array with limit curves
tan	- Array with tangent definition curves
m	- Array with flags defining the type of mid curves
	Eq. M: Mid curve is a R*3 curve
	Eq. M: Mid curve is a R*3 curve
mcur	- Arrar with mid curves

Optional parameters

None

Attributes

PEN	- Pen or colour number
LEVEL	- Level number
BLANK	- Visible (0) or invisible (1)
SFONT	- Solid boundary and dashed midcurves (0)
SDASHL	- Dashlength

Example

REF lim(10), tan(10), mcur(9);
STRING m(9)*1;

sur_conarr( #10, 4, #1, lim, tan, m, mcur);

Creates a conic lofting surface (type LFT_SUR) with spine curve #1. The number of patches in the V direction will be three since the number of limit curves and tangent definition curves is four.

Comments

The created surface LFT_SUR is of the procedural type.
