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

picadilly — Wed, 08 Jan 2025 14:51:42 GMT

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?

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:

#Author-

#Description-

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()

def export_stl(exportMgr, body, parameterValue😞

# Dateinamen aus dem Körpernamen ableiten

fileName = os.path.join("D:\\tmp", body.name + '_' + str(parameterValue) + '.stl')

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:

@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-parameter-configurations/td-p/13784721

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.
