[ConvertToPolygon() - Resolution]

Thanks, I will copy your explanation into the wiki if you don't mind.

[ConvertToPolygon() - Resolution]

I'm not sure which resoltuion to use for ConvertToPolygon().  http://developer.vectorworks.net/index.php/VS:ConvertToPolygon

 

<50 is obvious to less.

90 and 100 convert a cirlce to 32pt polys and 150 to 64 pt polys.

In this case 90 should be enough as even in renderworks my eyes can't spot a difference to the higher resolutions.

 

It would be good to know how the resoltution effects the outcome (why do 90, 100 create the same ) and if there is a maximum value.

 

 

regards, Patrick

[Help finding center of Symbol!]

To make sure the center stays at the same location  the bounding box must always have the same size.

This can be accomplished by palcing an invisible circle into the symbol. ( set fill and penstyle to empty.)

 

[Help finding center of Symbol!]

This node gives you the center of the Bounding Box.

[vs.DoMenuTextByName(), 'Rebuild NURBS...']

I looked it up in the source

 

This list should contain all the real nams.

 

univ_nams.txt

[vs.DoMenuTextByName(), 'Rebuild NURBS...']

The internal name can differ from the display name.

In your case it's Rebuild Curve/Surface

[Get Active LineStyle]

FPenPatN is the solution.

 

thanks

 

 

 

[Get Active LineStyle]

It might be obvious but I can't find the fucntion that returns the active LineStyle (Attribute Palette).

Can someone give me a hint.

[Create and export custom Reports - Vectorscript or SDK?]

You can find additional indo and more examples on http://www.vectorlab.info

 

I would recommend you pyodbc (or pypyodbc*) for the sql connection. It is easy to use, more stable and performs better than the vs. functions.

 

* Almost totally same usage as pyodbc ( can be seen as a re-implementation of pyodbc in pure Python )

I need to call a Pythonscript (200 Lines!) wrappt in a VectorScript.

Can you tell me how to get it between the brackets in VS?

[New Nodes 2018]

Function is a great timesaver node.

 

Here is a version with two more optional params.

I have to contain myself from using it to extensive because the readability of the code could suffer.

It would be great for the future if the function was displayed on the node.

[Delete Marionette Menu Commands]

Couldn't find a description in the online help. How is it done?

 

[New Nodes 2018]

thanks Dom,

 

I wonder why the criteria-dialog only calls a string-dlg as there is a more sophisticated dialog available.

 

Here is the alternative version:

[Record fields not updating after script]

Hi callum,

 

try it with ResetObject(handle)

[Rotating custom objects?]

Hans,

 

you just mentioned the solution. I forgot that there is a transfrommatrix-node.

The Rotate3D node could be fixed by checking the type for PlugIn objects and

using TransfMatrix in case.  (@Marissa Farrel   :))

[Rotating custom objects?]

Run it in 3D view and it will rotate.

 

 

[Rotating custom objects?]

Hi Hans,

could you provide a vwx file to reproduce the problem.

 

[Developer Tip: Using vs.Handle Attributes]

Hello together,

 

when using the pydev debugger I noticed that vs.Handle provides some attributes that make scripting a bit more comfortable.

Hopefully more attributes will follow.

 

 

def test():
    vs.CreateText('Hello!!')    
    h = vs.LNewObj() 
            
    print ('Type', h.type)
    print ('Parent', h.parent)
    print ('Parent Type', h.parent.type)
    
    

regards,

Patrick

		CURRENT_DOC = 0 
		Res_List, NumItems = vs.BuildResourceList (SYMBOL_DEFINI_TYPE, CURRENT_DOC, '')
		
		for i in range (NumItems):
			# Die Resourcelist beginnt nicht wie üblich mit dem Index 0 sondern mit 1 
			i += 1
			
			h = vs.GetResourceFromList (Res_List, i)		   
			
			syms.append ( vs.GetName(h))
		
		return syms
	###

	this = Marionette.Node( 'Get Sym' )
	
	sym_list = get_SymDefs_in_File ()
	
	sym_popUp = Marionette.OIPControl( 'Syms', Marionette.WidgetType.Popup, 0, sym_list)
	
	sym = Marionette.PortOut()   
	
	
def RunNode(self):
	sel_idx = self.Params.sym_popUp.value
	self.Params.sym.value = self.Params.sym_popUp.popupChoices[sel_idx]

 

Unfortunately you have to run it to refresh the popup values.

 

[global variables in a marionette script]

I've changed the Marionette.py to make it capable of showing the exceution order.

I think this can also be helpfull in other cases then global var handling.

 

You have to replace the Marionette.py inside the marionett plugin by the attached one (on your own risk).

It only shows the order on the first outport if there is a vw class named 'mrnt_show_order' in the doc otherwise it shows the number of output values as usual.

A magician never reveals her secrets

 

In all seriousness, I'll be more than happy to give you a run down of my tricks once I stomp out some of the work I've got going on here. I've been a little swamped with testing 2017 features/installers/etc., but I would imagine once we release I should have the reigns loosened up on me at least a little. (Not that they're incredibly tight to begin with - how do you think I learned Marionette AND Python in less than a year?!)

I'll keep in touch on this  

 

I hope meanwhile you found time to finish your script.

I'm still curious about your solution.

 

[global variables in a marionette script]

Hi Dom,

 

handling global vars looks like a dangerous thing to me.

You have to be very carefull when connecting the nodes because it can change the flow of the network (first connected -> frist executed)

which may lead to inconsistent values. (global var is accesed before assigned...).

 

It seems that the flow also depends on the node from which you run the network.

 

I've attached an example.

 

regards

[Moving a linear array]

You got it pat

 

I could solve it by replacing the += with .append:

 

def RunNode(self):

	dir = self.Params.dir.value
	obj = self.Params.obj.value
	
	a = 0
	b = self.Params.step.value
	c = self.Params.count.value	
	list = []
	if c != 0:		
		list = [a+n*b for n in range(c)]
	objs = []
	for i in range(len(list)):
		if dir == 0:
			objs.append (vs.HDuplicate(obj, list[i], 0)) # Changed += to append
		elif dir == 1:
			objs.append (vs.HDuplicate(obj, 0, list[i])) #  Changed += to append
		self.Params.array.value = objs

 

The node creates 5 duplicates so you get 6 object s in total at the end. The original was not passed out the Linear Array node.

I appended a Delete-node to the Line-node, maybe you want to at it rather to the output list of linear array.

[Get WS Cell Object Handle]

Thanks pat.

I needed some attempts to get back from the str to the vs.Handle.

 

The cells get filled with this code:

h = vs.WSScript_GetObject()
h_str = str(h) 
vs.WSScript_SetResStr(h_str)

Then another script iterates trough all objects and compares the handle strings:

 

def get_handle_from_str (h_str):
	h_dict = {} # key: handle_str val: handle

	def collect_handles(h):
		nonlocal h_dict
		h_dict[str(h)] = h 
		
	vs.ForEachObject (collect_handles, 'All')
	
	try:
		h = h_dict [h_str]
	except KeyError:		
		print ('Handle could not be found.')
		h = None
	
	print (h_dict)
	return h

# EXAMPLE
h = get_handle_from_str ('AEC62080')
vs.SetSelect (h)

It's kind of unpracticle and carries the risk if inconsistency but it works.

[Code Completion]

Hi Matt,

 

any Python-IDE can do this.

 

You can either put the vs.py next to your other py modules or better add a search path to the project that links to a folder where the vs.py is located.

Then you have to import it in the modules where vs-functions are called.

 

import vs

 

I use pydev for eclipse. The search path can be added in the project properties.
