Function Documentation

align_al()

module align_al	(	a	= z_axis_ci,
		r	= z_axis3d_ul,
		rp	= 0,
		ar	= 0,
		to	= origin3d,
		ro	= zero3d
	)

Align an objects Cartesian axis to reference line or vector.

Parameters

a	<integer> The Cartesian axis index to align (x_axis_ci, y_axis_ci, or z_axis_ci).
r	<line-3d | line-2d> The reference line or vector.
rp	<integer> The reference-line alignment point (see table).
ar	<decimal> Axial roll about r (in degrees).
to	<vector-3d | vector-2d> Translation offset about r.
ro	<decimal-list-1:3 | decimal> Rotation offset about r (in degrees).

The origin will be a translated to the specified alignment point for the reference line r.

rp	alignment point
0	none (no translation)
1	initial
2	median
3	termination
4	initial + termination

align_ll()

module align_ll	(	l	= z_axis3d_ul,
		r	= z_axis3d_ul,
		lp	= 0,
		rp	= 0,
		ar	= 0,
		to	= origin3d,
		ro	= zero3d
	)

Align a line or vector to a reference line or vector.

Parameters

l	<line-3d | line-2d> The line or vector to align.
r	<line-3d | line-2d> The reference line or vector.
lp	<integer> The line alignment point (see table).
rp	<integer> The reference-line alignment point (see table).
ar	<decimal> Axial roll about r (in degrees).
to	<vector-3d | vector-2d> Translation offset about r.
ro	<decimal-list-1:3 | decimal> Rotation offset about r (in degrees).

The specified alignment point for the line l will be a translated to the specified alignment point for the reference line r.
