Maybe you need a special feature, go into Macros_recipes and Code_snippets, Topological_data_scripting.
My macros on Gist.github here complete macros Wiki and forum.

Re: Align Section Plane to selected Face

Post by jaisejames »

Thank you all for quick support. I will study these macros.
My aim to Draft section plane work automatically align

First I will have to create Boundbox size based on Section plane linked objects[as given code]. Then I need to align to selected face based on above macros.

Code: Select all

import Part			
ObjectsList = [ sub.Shape for sub in obj.Objects ]
pc = Part.Compound(ObjectsList)
obj.ViewObject.DisplayLength = pc.BoundBox.XLength
obj.ViewObject.DisplayHeight = pc.BoundBox.YLength
Also align based on Draft Axis. so I can generate sectional view quickly.

i am able to create a macro. but it is not working. pls see the below code

Code: Select all

import Arch, Part
import FreeCAD as App
import FreeCADGui as Gui

v = Gui.activeDocument().activeView()
class Select_object:
	def __init__(self,view):
		self.SectionPlane = None

		self.view = view
		App.Console.PrintMessage("choose the SectionPlane\n")
		Gui.Selection.clearSelection()
		self.klick_event = self.view.addEventCallback(
			"SoMouseButtonEvent", self.choose_SectionPlane)

	def choose_SectionPlane(self, cb):
		if cb["State"] == "DOWN":
			sel = Gui.Selection.getSelection()
			if len(sel) > 0:
				self.SectionPlane = sel[0]
				Gui.Selection.clearSelection()
				self.view.removeEventCallback(
					"SoMouseButtonEvent", self.klick_event)
				self.klick_event = self.view.addEventCallback(
					"SoMouseButtonEvent", self.choose_Face)
				App.Console.PrintMessage("choose_Face_to_Align\n")
	
	def choose_Face(self, cb):
		if cb["State"] == "DOWN":
			selectedEdge = Gui.Selection.getSelectionEx()[0].SubObjects[0]   # select one element
			sel = Gui.Selection.getSelection()
			if sel:
				self.view.removeEventCallback(
					"SoMouseButtonEvent", self.klick_event)
				self.Align_SectionPlane(self.SectionPlane,selectedEdge)

		ObjectsList = [ obj.Shape for obj in SectionPlane.Objects ]
		pc = Part.Compound(ObjectsList)
		diagonalObject = int(pc.Shape.BoundBox.DiagonalLength)
		plr = plDirection = FreeCAD.Placement()
		
		if hasattr(selectedEdge,'Surface'):
			print "surface"
			########## section direction
			yL = selectedEdge.CenterOfMass
