TCL Command ARCXLINE

Syntax

ARCXLINE arg1 arg2 arg3 arg4 arg5 arg6 arg7

Description

Definition of an arc as a parametric line through a point of intersection and the radius. Further options are to be set.

Arguments

Minimum number: 4

arg1

Value	unit	Meaning
name	TEXT	Name of the parametric line

arg2

Value	unit	Meaning
radius	LCROSSD	Radius
rvar	TEXT	Radius specification by reference to a variable of type LCROSSD

arg3

Value	unit	Meaning
LSECT	KEYWORD	Center point defined by 2 reference lines.
POINT	KEYWORD	Center point defined by a point (PCART)

arg4

Value	unit	Meaning
ref1[:i]	TEXT	Name of the 1st reference line of the center point or point reference (PCART); the optional suffix ":1" or ":2" determines the number of the point of intersection if an arc is part of the intersection. As there can be up to two points of intersection, one of the two must be determined. This can be on either the first or second clipping line.

arg5 (arg3 = LSECT)

Value	unit	Meaning
ref2[:i]	TEXT	Name of the 2nd reference line of the center point; the optional suffix ":1" or ":2" determines the number of the point of intersection if an arc is part of the intersection. As there can be up to two points of intersection, one of the two must be determined. This can be on either the first or second clipping line.

arg6 (arg3 = LSECT) or arg5 (arg3 = POINT)

Value	unit	Meaning
++	KEYWORD	The directions of the rays enclosing the arc can be selected using a keyword. Each parametric line has a defined direction. The "+" sign means positive direction, starting at the point of intersection, and the "-" sign means the opposite direction. If a point reference is selected, the directions are to be interpreted in terms of the cross-section coordinates.
+-	KEYWORD	See above.
-+	KEYWORD	See above.
--	KEYWORD	See above.

arg7 (arg3 = LSECT) or arg6 (arg3 = POINT)

Value	unit	Meaning
CW	KEYWORD	Arc in a clockwise direction
CCW	KEYWORD	Arc in an anticlockwise direction

Scopes

CSECTION/CLINES

Examples

ARCXLINE "Arc1" 5.00000 LSECT "L1" "L2" ++ CCW

The parametric line "Arc1" is an arc with a radius of 5.0 with the center in the point of intersection of lines "L1" and "L2". The rays that enclose the arc are the positive directions of the selected lines ("++"). The direction of the arc is defined as anti-clockwise (CCW).
