[JSON rest api calls in vectorscript]

 OK, the part of the code which I will not paste is the part how you update your certificates by the script on mac computers to make python accept them to communicate over TLS (SSL) (https instead of http).

caution should be exercised. 

[JSON rest api calls in vectorscript]

The forum allows me not to paste some code ... I think maybe for security reasons.
 

Or your testing api request:

import urllib.request
import json


api_url = "https://jsonplaceholder.typicode.com/todos/1"

result_string = ''
with urllib.request.urlopen(api_url) as f:
   result =  json.loads(f.read().decode('utf-8'))


vs.AlrtDialog(str(result))

 

An other real example with a http request url, if you can't get https to work

		'lon': ('E','W')
	}
	compass_str = compass[type][0 if d >= 0 else 1]
	return '{}º{}\'{:.2f}"{}'.format(abs(d), abs(m), abs(s), compass_str)

[Marionette Node to insert symbols in rows]

Oh, this is an old code and not very nice one. Without testing:

1. The vs.GetType should replaced by:

vs.GetTypeN(res)

2. The node returns not the Symbol Name. That means the node itself insert the Symbol. In fact it looks, like the output just returns the last inserted symbol. Which means the node should insert the symbols in the number of rows and should do the job but not returning the resulting symbol handles. With that node, you can't use the output useful disconnect symbol node and print debug node.

Agree with Letti
I would vote for the smart solution using the function node without wrapping.

[Reading Record Info from Other File]

Hi
A possible workaround I once used is:
1. I had a big library document with much of Elements. Importing, reading informations, delete/purge would be time-consuming.
2. On the library document running a script after every change. The Script dumps the needed informations to a file which contains the metha-data from the library file
3. Or alternatively dump to a text object inside a symbol (I think does not work with too much data because of text size limitation maybe) and just import that index symbol to read source data
4. If the process should be automated there could be used a custom "save" command which dumps the data automatically before saving the file

[Question on DomC's "Extrude along Path with Ref point" Network]

Hi

After specific Manipulation there is a need of ResetObject. Some commands included the proper Reset of the Result some not. In my Script you can see, that if you remove the reset of the parent object, the visible geometry is different from what you get if you edit the path extrude and exit it (same effect as resetting). If for your example it is not needed (because you do other actions with the result which may reset the objects itself) you can delete it. Beside that, it would not have a big speed impact because in a script every reset is added together if you reset 10 times it will reset just once anyway.




"Punktkörper" is called "Mesh". 
Not sure I  understand this question. You mean the result of your solid boolean operation is a mesh? Normally this is not the case at all. The Result of using solid boolean node should be a generic solid not a mesh. Even if you use a mesh in a solid operation the result is normally converted to a solid not a mesh.
 

[Trigger a specific Event on an Object]

vs.ResetObject() actually regenerates the pio and change the geometry after with vs.SetRField() parameters are changed and I tried also 1167. The specific thing here is, that the cabinet contains also plugins (Custom Parts) which maybe are not reseted as expected and the additional relations of fittings interact with the parts and not directly with the cabinet maybe. I will give accessing the sub-pios of the cabinet and if that not will not be of use i will wait for another solution. 

Already I am in contact with the genius devs from extragroup but there are always some other more important tasks to address so I wondered if i could bypass this limitation on the script-side.
 

[Trigger a specific Event on an Object]

Thank you for that feedback Hippocode and JBenghiat. 
Of course you are absolutely right. I should have been more specific about what I'm trying to do in the first place. I have a script that reshapes interiorcad cabinets together with custom parts and milling pios which are attached to that objects.
Unfortunately, applying a vs.ResetObject() to these objects disconnect their connections to the fittings and other associated elements. The PIO itself runs a code, that is able (if nothing went wrong) to keep that relations. 
So there are some options:
1. The developper of that PIOs implements an API which can be triggered by vs.ResetObject()
2. I find a way to fire the right events to that PIO so that it is forced to regenerate (It also has a button to update)
3. It is maybe a bug in the vs.ResetObject()

#1 is maybe the best option but if it can be controlled by the script itself it would be seen prefered.
Here what the script does. It is open source and addresses a very often mentioned requirement from customers.
 

 

[Trigger a specific Event on an Object]

Hello
The question is maybe naive. As I know, there are Events that happens while the usage or code-run of an object. As example 3 for reset, 5 initProberties etc. Is it possible at all, to fire such an event on a PIO from outside. Or trigger the PIO with something more controlled than vs.ResetObject()?

To be specific:
1. Fire a standard-Event like 3 (I think vs.ResetObject() does that) or 41 or 43?

2. Or a custom event. Lets say I have a button ID inside the PIO like:
(theEvent, theButton) = vs.vsoGetEventInfo( )

With simple words: Can I push the button from outside with something other than the Mouse cursor?

Thanks

[Add Tool to Workspace]

Hello

So far it works implementing a Tool in the Workspace and Creating a new Palette Group. So far it works for path Objects or Point Objects (vso). Event Enabled or not Event Enablet. But I can't get it to work with a VST. I tested with this tool "Blindfront" This one here:

As soon as I manually drag it into the workspace the tool works. and also after that the tool i added with the script works. So far the workspace itself looks identical if i drag manually the tool in the workspace as if i create the tool by script. I think I am missing some important parameter here.
The Tools is placed into the palette and is shown ad expected but not the tool can't be selected. 

Anybody can help?

Here My small test:
 

#Get Group Palette by Index 1 (0 is Construction palette)
pName = vs.ws2GetToolAt("", 1)
result, outDisplayName, outShortcutKey, outShortcutKeyModifier, outResourceID = vs.ws2GetToolInfo(pName)

vs.AlrtDialog('Put Tool in ' + outDisplayName)

#The .vst is already in the Plug-Ins Folder

# id of group palette
tsPath = pName #outDisplayName#GetPalettePath('Werkzeuggruppen')

tsName = 'NewPalette'
tsNameUniversal = tsName #can be a uuid or just here for Testing 'NewPalette'

[Working with vs.GetPt() & Event based Plug In Objects]

It looks for interaction with the VW API it would need a very different kind if integration of the python language or additional APIs which are able to communicate with the python script. Which maybe needed a very big effort or would not pay out the effort. I think the reason it not, that python can't pause.

If i draw an object and then get after that some informations from that object, somehow the object was created in Vectorworks (not drawn, but minimum defined). So The python script here waits for the Object created by the VW binary and so i think it could be possible the python script also can await the user interaction. So I guess it user interaction may be is not technically limited because of python itself. 
 

[Working with vs.GetPt() & Event based Plug In Objects]

Also tried to solve that issue. But without a big success. You can run the complete python as a callback of GetPt. But Nested callbacks are not possible. So just one click can be done.

My Workflow is to create a main script as a Vectorscript. I collect the clicks and user interaction and then run the python script inside this script. Also it is possible to run several python scripts inside the pascal wrapper. So far no better solution I can see.

It gets two clicks in the drawing and draw a preview rectangle. Then save the result in the value reprository, where the python script after that can load the data. It you want to pause somewhere your python script and make a user interaction this workflow is not possible.

[Get Handle to Objects in section Viewport]

The Marionette Result of scanning the OV of a Viewport from 0 - 5000. I think it would need a function like calling an array but the only array what is callable for object-variables is a point tuple. 

[Get Handle to Objects in section Viewport]

Thanks for your worthwhile feedbacks. So far my strategy (But I do not know if it will work reliable enough)

1.  Inside the Section there is a Section Line Type 86 that contains the position of the section and a direction matrix
2. There are Informations on the Section VP directly that tells, if section is horizontal or vertical
3. The VP cache Group contains the projected geometry of the elements 
In combination of this 3 information it is possible to compare the Design-Layer coords and the section coords.

I build some functions to test what works. So far i see the following stumbling stocks:
- There are differences if the horizontal section was created from clip cube or from sectioning a VP
- VP cache has not the same informations if the objects behind section plane are disabled
- So far my function are not secure to return always the right informations

Additional it would help to check classes and attributes to be sure not targeting an invisible object etc.
With this 3d Methods it is possible to manually make a relation between a coord point inside the section annotations and the object on the design-layer. 

The shakiness of this strategy here is, that the Method of traversing the VP to collect Section-Line and Section Geometry is maybe not reliable enough or can wreck after an VW Update.
Further it can be tricky to get positions of rotated and nested object rotations. That would be the the hardest part. Even the Data-Tag hat some (fixed) issues to find the Objects in every situation so I do expect that would be really expensive to solve that.

Also I saw, that I corrupted some VP after working on them with this scripts. But I think this was because of creating Test-Marker-Objects inside the VP. At the end, this would be a "read-only" access to the VP which should not corrupt anything -SHOULD.

I will pause working on that specific feature ☺️


 

[Get Handle to Objects in section Viewport]

Hi
Does anybody know, how to get a handle related to the geometry of the vp cache "vs.GetVPGroup(h, 3) or the VP coordinates to the Object on the Design Layer?
Target would be tagging or annotate Elements in a Section viewport by script. Somehow it would work because the data-tag can also can access to this elements. 

I can imagine that it is necessary to evaluate the original object of a location from the vp coordinates and the section plane. Or is there an other solution for that?

Hi
Hm, I was quite sure "SetTexBitFeatureSize" changed once the texture size. However I would confirm, the size is always 10mm, 1cm or 0.01m.

So far what seems to change the size (but not as we needed)

1.  Changing the Document units to the imperial unit-system inch. Texture size is now 1 inch instead of 10mm but somehow other units do not change the size.
2. If I change the line

vs.SetTexBFeatureEnd(hTextureBitMap, int(resolutionx*100), 0)

The Size is 100 times bigger but this value is not update till i go into the dialog box of the texture.

Also Tried:
Layer Scale, Different units, scaling the image, scaling the paint. Reload Document.

So it seems, we have not a solution for the default texture size yet. 

[Problem rotation parametric symbol]

OK I can reproduce two issues. Wich looks not like a messed up script it looks like an issue with the style duplication and replacement on a new document.

2. import and Edit the style and import and replace new from source

The Styles Marionette PIOs are a new System since VW 2023. Before that we got the workaround with Script-Symbols inside of the PIOs which worked quite good at the end. It is very hard do foresee all workflow and issues in development and so I think the styles need a little time to loose the growing pains. 

I will bug-submit those two issues.

obj = vs.FSActLayer()
num = vs.GetVertNum(obj)
units = vs.GetPrefReal(150)

output = []
for i in range(1, num + 1 ):
	p, vertexType, arcRadius = vs.GetPolylineVertex(obj, i)
	
	if vertexType in [3,4]:
		arcRadius = vs.GetPolylineArcMaxRadius(obj, i) / units
		
	else:
		arcRadius = 0
		
	res = p, vertexType, arcRadius
	output.append(res)

vs.CreateText('\r'.join(map(str, output)))

 

[vs.GetPolylineVertex()]

Hi
Did not find some hints in the forum, so a deside to make a new post. I think I am doing something the wrong way. But What I want to do is, to grab directly data of a polyline with arcs and radius without converting them or decomposing them. So the GetPolylineVertex command looks like the right workflow for this. But what I can see (depended how the polyline is created or which tools are used to modify it) it returns the radius not directly on the returned point index. 
The only pattern I can see is, that the last radius which was returned before the vertex point is the right radius. I can imagine, that this workes as designed to bequest the value to the next value which is 0. But somehow not logical is, that other points which are type 0 (edge) contains the radius value. Someone see behind the scene here?
