wanted: script/addin for automated change of parameters and stl-export

[picadilly]

I would need a tool and I could image that others had the same need before me and maybe something exists already:

I do an open-source-project called osVAC neo. For details see: osvacneo.de

It is similiar to plumbing:

you have a few basic parts, like bows and T-connectors, but you need them in lots of different sizes and combinations thereof.

So, I did the designs und f360 and get the different sizes I change parameters.

To generate the stl-files I have to:

1) change the desired parameters

2) exports part(s) als stl (and step-files)

3) repeat the above for all desired combinations of parameters

Question:

Does anybody know a tool, which already does this or something similiar?

There's a script in the store called ParameterIO that will export and import parameters.

Thanks, I will have a look at it.

1. There is the Configurations functionality that will make this a lot easier. 

2. There are at least 2 plugins that can make 23D printing easier.

What is the "Configurations functionality" about? Maybe something, which is not included in the free version?

[picadilly]

I forgot to add:

thanks for your reply. I should have written that in the first place:-)

I will have a look for the other links, you posted.

Unfortunately it isn't included in the free subscriptions 😕

Here is a link to the documentation.

A good friend created the attached piece of code for me. I got that to work. I will try to work from there, but I hoped somebody would have done more work prior to me:

import adsk.core, adsk.fusion, adsk.cam, os, traceback

def get_immediate_children(component😞

    # Get the child occurrences (components) directly under the specified component

    child_occurrences = component.occurrences

    # Extract the actual component objects from the occurrences

    child_components = [occ.component for occ in child_occurrences if occ.isVisible]

    return child_components

def set_parameter(app, design, parameterName, parameterValue😞

    ui = app.userInterface

    userParameters = design.userParameters

    userParameter = userParameters.itemByName(parameterName)

    if userParameter:

        userParameter.expression = str(parameterValue)

    else:

        ui.messageBox('User-Parameter "{}" nicht gefunden.'.format(parameterName), 'Fehler')

        return

    # update parametric text plugin

    app.fireCustomEvent('thomasa88_ParametricText_Ext_Update')            

    adsk.doEvents()

    stlOptions = exportMgr.createSTLExportOptions(body, fileName)

    stlOptions.sendToPrintUtility = False # Setze auf True, wenn du die Exportdatei direkt drucken möchtest

    # Körper als STL exportieren

    exportMgr.execute(stlOptions)

def run(context😞

    ui = None

    try:

        # Zugriff auf Fusion 360 UI

        app = adsk.core.Application.get()

        ui = app.userInterface

        # Dokument und Design erhalten

        product = app.activeProduct

        design = adsk.fusion.Design.cast(product)

        if not design:

            ui.messageBox('Kein aktives Fusion 360 Design.', 'Fehler')

            return

        # Get the root component

        root_component = design.rootComponent

        # Get the immediate child components under the root component

        immediate_children = get_immediate_children(root_component)

        # User-Parameter ändern

        parameterName = 'HoseDiameterInner'  # Name des zu ändernden Parameters

        for parameterValue in range(30, 50, 5😞

            set_parameter(app, design, parameterName, parameterValue)

            # Export

            exportMgr = design.exportManager        

            for component in immediate_children:  

                export_stl(exportMgr, component, parameterValue)

        ui.messageBox('Export erfolgreich abgeschlossen.')

    except:

        if ui:

            ui.messageBox('Fehler aufgetreten:\n{}'.format(traceback.format_exc()))

If you want to post code and need help with it:

1. There is a Fusion API Forum section where this gets better feedback

2. Place your code in code tags:

[andrew_tchircoff]

@picadilly this is probably way to late but I've made as script that does something like that: https://forums.autodesk.com/t5/fusion-api-and-scripts-forum/batch-exporter-script-for-different-para...

[picadilly]

Cool. I wrote a reply at the link, you mentioned.

Hi,

none of my business but figured I should just point it out when I noticed it.

I noticed that the code loops over the whole component rather than bodies, and there's a chance it may fail in the case scenario where it's made of multiple bodies.

and reuse objects – like exportMgr and userParameters, instead of recreating them each iteration, saves repeated calls to the API.

Hope it help,

Ricky

I have not looked at it yet. But as I did something similiar:

In my case, I export components. Exporting all bodies separately is not what I need - at least most of the time.
