Hi , is this the one

VoronoiObj (1).vwx

I would like to try the voronoiObj.vwx file, but when I press the link I get  an error message: We could not locate the item you are trying to view. Could you perhaps upload it again?

This should be the one!

VoronoiObj.vwx

 

Also - I updated the first two posts in this thread to have their original attachments. You will find, though, that this/these files may require external python libraries. In 2017, this is easy to remedy, but 2016 is significantly harder - I never even got it to work.

 

EDIT:

Here's the same file working in 2017 on Windows. I'll work on updating it to be cross platform soon.

Hi,

I am trying to install numpy and scipy  without success.

I am able to install - using pip - a previous version of either numpy and scipy but I am not able to see them.

I placed numpy and the info file and the same for scipy into PythonExternal in Library inside Vectorworks folder, but modifying the voronoi example bring up a - very large - error window.

So, I need a better instruction on installing the requested version of the package.

Thank you

Roberto

Hi roberto,

 

please tell us what OS and VectorWorks version you use.

Hi Roberto,

 

In 2017 we introduced a command that would help to install python packages for you. 

 

Can you try this for me?

 

1) Exit the Vectorworks application

2) Go to the Python Externals folder where you placed numpy and scipy, remove the numpy and scipy files you have placed there

3) Open the attached file in Vectorworks 2017

 

When you go to move the object or change any parameters, a dialog should pop up asking if you want to download numpy, click OK and then a dialog will pop up asking if you want to install scipy, click OK again, wait for the packages to install, and then you should be able to use the Marionette object without any issues.

 

I had some coworkers here test to make sure this works on both Mac and Windows platforms, so please let me know if you are still encountering any errors.

 

Thank you!

Hi Marissa,

I deleted numpy and scipy from PythonExternal (I have a copy in Python directory) and get the error in the attached image:
I am not able to remove numpy and scipy from /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python (sudo rm -R numpy*: operation not permitted…)

Any clue?

 

grazie

Roberto

Hi Roberto,

 

I'll have to look into this more, I've never received this error.

 

It shouldn't be important to remove the libraries from your copy of Python, Vectorworks ships with its own Python 3.3 version.

 

If you go to your Vectorworks 2017 User Folder, is there a folder called Python Externals there? That is where this script should be installing the numpy and scipy libraries. I can forward this on to the engineer if we don't get it working soon.

 

Also, which Service Pack are you using?

 

Thanks!

Marissa

@MarissaF

I checked with the German Version SP2 on MacOSX 10.10.5 and Windows 10 SP2. Without any issues here.

That's Great ... not looked in Detail into this, but those modules seem to open a pretty wide new playground.

[Marissa Farrell]

@DomC

Thanks so much for checking! I'm glad they are working.

I'm hoping to get some sort of documentation on how to use the command to install external libraries going in the future - currently I just don't have the time!

The biggest thing is to make sure that you're using a link to a wheel file that corresponds to your operating system and Python 3.3 (since it's the one Vectorworks uses)

The link address can either be online or a local wheel file.

Hi Marissa

I don't have "Python Externals" in user folder, nor in the root or in the Library. I created a "PythonExternals" inside Library inside Vectorworks application folder as from some instruction I got on the list. Now I created some "Python Externals" in some locations: but I continue to receive the error of lacking permission (see attached screenshot) and none of Python Externals folders get populated.

My service pack is SP3 build 356720.

Thanks Roberto!

 

It looks like there may be some permissions errors, or some script errors, when the VerifyOrGetLib command is trying to create the Python Externals folder in your 2017 User Folder.

 

Are you using a localized version or the English version of Vectorworks? Is your computer using a language other than English?

 

As a test, could you create a folder in your 2017 user folder called "Python Externals" as shown below and try running the network again?

[PVA - Admin]

You may also want to give these steps a try, there are some permissions issues affecting other areas at the moment too:

Hi Marissa,

I am using the English version of Vectorworks on an Italian language system.

I made this test:

1) created a new user;

2) launch VW, inserting the serial, ecc.;

3) running VoronoiObj_v2017_CrossPlatform_MFarrell;

4) I was asked to authorize the download of numpy and later of scipy, I allowed;

5) the Marionette script ran as expected;

6) I checked that a Python External folder was created and populated in User Folder; I found also a copule of other files, as from you screenshot;

7) I copied the folder and files on user folder of my usual user, assigned ownership to myself;

8) running VoronoiObj_v2017_CrossPlatform_MFarrell gave me the usual error of privileges.

 

I also tried to create an empty Python External as from your suggestion but continued to receive the error.

 

Thank you

Ciao

So it sounds like we've at least narrowed it down to your user account, if I'm reading correctly.

 

Are there any special characters in your account name or the path to your user folder?

Can you double check again and make sure you have the appropriate permissions on your user folder?

 

I'm assuming you quit and restarted Vectorworks on your personal account after copying the files over, if not, please do that as well.

 

I'm sort of at a loss at this point, I haven't been able to reproduce this and haven't heard of any other users experiencing it.

Hi,

Yes, narrowed to my user account, and no special characters...

Hi

I try to do something organic out of that in 3D. Often requested from students and teachers. My approaches:

 

1. Project Points on a NURBS (Not satisfying completely because on steep surface there had to be some kind of compensation  )

2. Making path extrudes for skeleton

3. Round an offset path (project an offset path) Someone knows how to round a nurbs curve?

4. Add all those path extrudes (which maybe failed because or geometrical inconsistencies) and get a soft and organic form ...

 

Or is it possible to just meshing (I think it maybe could, because I think there are python based examples which can do this?) the whole geometry and using python for calculating all mesh points. 

Hopeless?

Hi all,

 

I'm attempting to install numpy in Vectorworks 2019 using the file Marissa provided in the thread above (VoronoiObj_v2017_CrossPlatform_MFarrell.vwx). It isn't working, I get an error message that says 'module numpy cannot be installed' when I attempt to move the object inside the file. Marissa, are there updates in 2019 that make the file from 2017 incompatible?

 

Thanks!

 

 

[rDesign]

Using Vw2024 update 7, when opening the 'VoronoiObj_v2017_CrossPlatform_MFarrell.vwx' file that @Marissa Farrell provided in THIS post, I get the same 'module numpy cannot be installed' and 'module scipy cannot be installed' errors.

 

When I get the dialogue box that says numpy and scipy are not installed, I click OK, but then it gives the error.

 

Any ideas on how to get this to work? Thanks.

 

[Marissa Farrell]

@rDesign

Give this a shot, let me know if it fails. We added new functionality a few years ago to simplify the library install method.

It said that it installed numpy and scipy successfully, so I think it worked. Same file also worked in Vw2025. Thanks!

Yep! I actually updated this in 2025 and exported to 2024.
