Fast toggling the visibility of non-datum constraints in FreeCAD 1.0

Inspired by this Reddit post on the topic, in FreeCAD 1.0 it would be pretty nice if a person could swiftly hide (and show) all non-datum constraints -- just the geometrical stuff is of interest here.

So I wrote a little Python macro that does, which took more time to document than it took time to write. You can bind it to a custom macro and subsequent hotkey of your choosing.

Here's what you should approximately expect to see once you have added the macro to your system:





Here's the Python code, you'll have to select it in the conventional way as there is no JS on this page:


import FreeCAD,Part
import FreeCADGui as Gui
from PySide import QtGui

# clear the report view
# you can remove the hash comment symbols from the 5 lines following this line if you want the Report View to clear out upon running this macro
#clear_console = True # or False
#if (clear_console == True):
#	mw=Gui.getMainWindow()
#	r=mw.findChild(QtGui.QTextEdit, "Report view")
#	r.clear()

doc = Gui.ActiveDocument
editing_view = doc.getInEdit()

if editing_view == None:
	print("oh dang, there is not an active Sketch edit in view - switch to editing a Sketch before running ToggleAllNonDatumConstraintsToOtherWorkspace.py")
	pass
else:
	obj = editing_view.Object
	if obj.TypeId == "Sketcher::SketchObject":
		constraints = obj.Constraints
		non_datum_constraints = []
		#print(constraints)
		for index, this_con in enumerate(constraints):
			#print(this_con.Type)
			if this_con.Type == "Coincident":
				#print("no op on Coincident type Constraints")
				pass
			elif this_con.Type in ["PointOnObject", "Horizontal", "Vertical", "Tangent", "Parallel", "Perpendicular", "Equal", "Symmetric", "Block"]:
				#print(this_con.Type, "is a non-datum constraint")
				non_datum_constraints.append([this_con, index])
			else:
				if this_con.Name != "":
					#print(this_con.Type, "is a datum constraint maybe  <-------------- named '", this_con.Name, "'")
					pass
				else:
					#print(this_con.Type, "is a datum constraint maybe  <--------------")
					pass
		#print(non_datum_constraints)
		constraint_indexes = []
		already_in_virtual_space = []
		for index, this_con in enumerate(non_datum_constraints):
			constraint_indexes.append(this_con)
			con_object = this_con[0]
			if con_object.InVirtualSpace == True:
				#print("in virtual space", index)
				already_in_virtual_space.append(this_con)
		print(len(non_datum_constraints), " non-datum sketch constraints matched")
		if len(non_datum_constraints) == len(already_in_virtual_space):
			set_all_to_virtual_space = False
			print("all non-datum constraints are already in the virtual space, switching them back to main space")
		else:
			set_all_to_virtual_space = True
			print("zero or some non-datum constraints have not yet made it to the virtual space, putting them there")
		for this_con in constraint_indexes:
			con_object = this_con[0]
			con_index_within_all_constraints = this_con[1]
			#print("setVirtualSpace", con_index_within_all_constraints, set_all_to_virtual_space)
			obj.setVirtualSpace(con_index_within_all_constraints, set_all_to_virtual_space)
