macro for hiding geometric constraints

[aster94]

hello,

I wrote a macro to hide all geometric constraints and show only measures (i.e. angle, radius, diameter, distances)
here a video showing its use: https://streamable.com/jhtdu

Code: Select all

import FreeCAD
__title__="Macro_HideGeometryConstraints"
__author__ = "aster94"
__url__     = "https://github.com/aster94"
__version__ = "0.0.1"
__date__    = "26/10/2019"

try:
	sketch_name = Gui.ActiveDocument.getInEdit().Object.Name
	valid_constraints = ['Diameter', 'Radius', 'Angle', 'Distance']
	constraints = list(Gui.ActiveDocument.getInEdit().Object.Constraints) # Get all the constraints of the active sketch

	for cnt, constraint in enumerate(constraints):
		#print(constraint)
		if any([c in str(constraint) for c in valid_constraints]):
			#print(constraint)
			App.ActiveDocument.getObject(sketch_name).setVirtualSpace(cnt, True) # Show
		else:
			App.ActiveDocument.getObject(sketch_name).setVirtualSpace(cnt, False) # Hide
		
except Exception:
    None

and to show again all constraints

Code: Select all

import FreeCAD
__title__="Macro_ShowAllConstraints"
__author__ = "aster94"
__url__     = "https://github.com/aster94"
__version__ = "0.0.1"
__date__    = "26/10/2019"

try:
	sketch_name = Gui.ActiveDocument.getInEdit().Object.Name
	constraint_count = App.ActiveDocument.Sketch001.ConstraintCount

	for c in range(constraint_count):
		App.ActiveDocument.getObject(sketch_name).setVirtualSpace(c, True)

except Exception:
    None

Any suggestion is well accepted since it is my very first script in FreeCAD
I would like to submit to https://github.com/FreeCAD/FreeCAD-macros what do you think about?

As a blocking point, your 2nd macro will only work on Sketch001, which isn't convenient.

Here a feedback where I commented changes.

__version__ = "0.0.1"
__date__    = "26/10/2019"

try:
	sk = Gui.ActiveDocument.getInEdit().Object # instanciate sketch itself for future use
	valid_constraints = ['Diameter', 'Radius', 'Angle', 'Distance']
	constraints = list(sk.Constraints) # to be checked but I think '.Constraints' already returns a list

	for cnt, constraint in enumerate(constraints):
		if any([c in str(constraint) for c in valid_constraints]):
			sk.setVirtualSpace(cnt, True) # Show
		else:
			sk.setVirtualSpace(cnt, False) # Hide
		
except Exception:
    pass # instead of 'None'

I didn't check this code, but you should be able to see the idea.

ahahahah yep, I missed it

here the updated versions

valid_constraints = ['Diameter', 'Radius', 'Angle', 'Distance']

try:
	sk = Gui.ActiveDocument.getInEdit().Object
	constraints = sk.Constraints # Get all the constraints of the active sketch

	for cnt, constraint in enumerate(constraints):
		#print(constraint)
		if any([item in str(constraint) for item in valid_constraints]):
			sk.setVirtualSpace(cnt, True) # Show
		else:
			sk.setVirtualSpace(cnt, False) # Hide
		
except Exception:
    pass

may i upload these to github?

yes please
upload them to https://github.com/FreeCAD/FreeCAD-macros/

Well read the Readme there so your header is compliant with requirements.
Also the Wiki page shall exists. Better also if you propose icons with your macros.
IMO it would be good that both macros are grouped in only one.

mmmmm the only way i can think about to make the two macro in only one would be to have a flag variable outside the macro, but i guess that this is not possible, is it?
Also i wasn't able to find a way from python to know if a constrain is visible or not. I mean that there are cases in which

Code: Select all

setVirtualSpace(cnt, True)

would make a constraint not visible. Is it possible to check if a constraint is visible or not?

[openBrain]

Code: Select all

isHidden=sk.getVirtualSpace(cnt)

To get both in one macro, I'd implement a logic like : if at least one constraint hidden then show all else hide geometric constraints.

Great, far away easier, i was trying to access the same with

Code: Select all

sk.Constraints[1].IsInVirtualSpace

but it wasn't working for some strange reason
During the next days I will send an updated version of the macro

EDIT 1:Anyway your isHidden unfortunatelly won't work in 100% of cases, if this button (https://www.freecadweb.org/wiki/Sketche ... rtualSpace) is pressed the result would be anyway true. Do you see any work around?

EDIT 2: from the wiki it says "move some constraints to virtual space two" then i guess (i am not checking the code) that the python function getVirtualSpace can return only boolean values and 2 is a valid true. Would it be possible to make this function return an int?
