The Right Question :

How to change the (normal) of line so the direction of extrude modifier will change also .
OR :
(making the extrude modifier have an option like local X,Y,Z direction)
in this way there is no need to attatch the line to another one with correct normal direction .

extrudeXY

This fn do the right job.
Options:
*theShape - spline that you need extrusion
*offset - extrude/offset value
*type - choose three type of extrusion:#center, #in or #out pivot alignement
*banking along the spline (on or off)

fn extrudeSplineXY theShape offset: type: bank: = if isKindOf theShape Shape do
(
	local ext = offset as float
	profile = SplineShape pos:(point3 0 0 0)
	addNewSpline profile
	addKnot profile 1 #corner #line (point3 (ext/2) 0 0)
	addKnot profile 1 #corner #line (point3 (-ext/2) 0 0)
	updateShape profile
	local sweepMod = sweep CustomShape:1 GenerateMappingCoords:on Banking:bank
	case type of (
		(#center): sweepMod.PivotAlignment = 4
		(#in): sweepMod.PivotAlignment = 7
		(#out): sweepMod.PivotAlignment = 1
	)
	sweepMod.shapes[1] = profile
	addModifier theShape sweepMod
	delete profile
)
extrudeSplineXY $ offset:10 type:#in bank:on

This is a way for you to

This is a way for you to develop your tool...

 
fn extrudeLine ey ez =
(
 
sel = $

select sel
modPanel.addModToSelection (Extrude ()) ui:on
$.modifiers[#Extrude].amount = ez
 
)
 
 
extrudeLine 5 10
