Description
This macro positions an object perpendicularly to the selected wire.
Usage
- Install the macro via the Addon Manager
- Select the path (may be an element or sub-element)
- Select the object to align
- Execute the macro
Script
Macro Perpendicular To Wire.FCMacro
# -*- coding: utf-8 -*- __title__ = "Macro Perpendicular To Wire" __author__ = "Mario52" __url__ = "https://wiki.freecadweb.org/Macro_Perpendicular_To_Wire" __version__ = "00.03" __date__ = "31/03/2020" import Draft, Part try: sel = FreeCADGui.Selection.getSelection() # Select an object lineSelected = FreeCADGui.Selection.getSelectionEx()[0].SubObjects[0] # first object the Path object or SubObjects myCircle = sel[1] # second object pointsDirection = [] pointsDirection = lineSelected.discretize(Number=500) # discretize the path line first selection v=pointsDirection[0].sub(pointsDirection[1]) # avec vecteurs 1 et 2 (direction debut ligne) r=App.Rotation(App.Vector(0,0,1),v) pl=FreeCAD.Placement() # placement object pl.Rotation.Q = r.Q pl.Base = pointsDirection[0] myCircle.Placement = pl del pointsDirection[:] FreeCAD.ActiveDocument.recompute() except Exception: print( "Select two objects. 1:The path 2:The object to align" )
Options
Essentially the line is cut in x points with discretize()
(for our purposes we default to Number=500
but cuts may be modfied between 0 to 499)
pointsDirection = lineSelected.Shape.discretize(Number=500) # discretize the path line first selection
1. The perpendicularity is calculated between 2 points:
v=pointsDirection[0].sub(pointsDirection[1]) # perpendicular of first > second point
2:
v=pointsDirection[-1].sub(pointsDirection[-2]) # perpendicular of last > before last point
pl.Base = pointsDirection[-1] # position base last point
3:
v=pointsDirection[100].sub(pointsDirection[101]) # perpendicular of point 100 > point 101
pl.Base = pointsDirection[100] # position base point 100
4:
v=pointsDirection[0].sub(pointsDirection[-1]) # perpendicular of first point > last point
pl.Base = pointsDirection[0] # position base first point
Other parameters to discretize()
are as follows:
# Discretizes the edge and returns a list of points.
# Forum thread: http://forum.freecadweb.org/viewtopic.php?f=12&t=16336#p129468
# The function accepts keywords as argument:
# discretize(Number=n) => gives a list of 'n' equidistant points
# discretize(QuasiNumber=n) => gives a list of 'n' quasi equidistant points (is faster than the method above)
# discretize(Distance=d) => gives a list of equidistant points with distance 'd'
# discretize(Deflection=d) => gives a list of points with a maximum deflection 'd' to the edge
# discretize(QuasiDeflection=d) => gives a list of points with a maximum deflection 'd' to the edge (faster)
# discretize(Angular=a,Curvature=c,[Minimum=m]) => gives a list of points with an angular deflection of 'a'
# and a curvature deflection of 'c'. Optionally a minimum number of points
# can be set which by default is set to 2.
