Batch rendering amd batch converting? with script

[Anonymous]

Is there a way to batch render and batch convert 3d cad models in fusion 3d with or without a script?

Is it possible to convert and render thousands of 3d models in an automated manner?

Thanks,

Arthur

Hi there,

We don't have that exposed formally through API, but we might be able to cobble this together. Some questions: 

- what file formats are you thinking? 

- render quality really depends on having good materials and lights, do you think these files will contain such data? 

- is the camera view you want to render defined in the file or an external parameter

- depending on quality and resolution, thousands of renderings could imply cost. The currency for rendering is cloud credits.

Any update on this thread?

There are a couple of things that would be possible today using Fusion to do the rendering and possibly keep the entire process local.  But it depends on what the existing data is and what kind of results are needed.  For example, if the data exists in one of the formats that Fusion is able to locally translate (IGES, SAT, STEP, SMT, and f3d), then you can create a new file by importing that data locally.  This is the equivalent of the "New design from file" command in Fusion.  Once it's imported you can manipulate the view to get the desired orientation and save the rendered image to a file.  This uses the basic rendering in Fusion.  Unfortunately there is not currently API support for the Rendering workspace and the ray tracing it provides.

If the model data is in another format you can use the Fusion API to upload it to A360 where A360 will convert it to the Fusion format so it can be opened in Fusion.  The local renderer can then be used to render and save the image.

thanks for the quick reply.  The locall rendering engine will suffice for now then.   I've seen an example or two for manipulating the camera but not on saving the rendered image.  Can you reference me to any examples?

Here's a script that demonstrates changing the value of a parameter through a series of values and capturing an image of the view at each step to create the images that could be used as an animation.  There is a know propblem where the size of the image isn't the same as the view.  This will be fixed in an upcoming update.  What's there still works it just that the size is slight off.

    try:
        app = adsk.core.Application.get()
        ui  = app.userInterface        
        des = adsk.fusion.Design.cast(app.activeProduct)

        paramName = 'Length'
        startValue = 10
        endValue = 15
        increment = .1
        resultFolder = 'C:/Temp/Animate/'
        
        param = des.allParameters.itemByName(paramName)
        currentValue = startValue
        param.value = currentValue
        
        cnt = 0
        while param.value < endValue:
            param.value = currentValue
            currentValue += increment
            adsk.doEvents()
            filename = resultFolder + "frame" + str(cnt).zfill(4)
            app.activeViewport.saveAsImageFile(filename, 0, 0)                
            cnt += 1
            
        ui.messageBox('done')
    except:
        if ui:
            ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

For my script I need to automate loading the CAD model (STEP file); however, my Fusion 360 script (python) crashes unless I manually open a STEP file first.

In this scenario, the script below runs but crashes with the error "Error: Autodesk Translation Services failed to translate the step file, please make sure the step file isn't corrupt!"

I just tested your program with a STEP file of my own and it worked as expected.  Is the filename being constructed correctly?  Are you also saying that your program works if you first manually open a STEP file or do you mean that you can manually open this STEP file but not from a program?

If I manually open the STEP file first, then it works.  Doesn't matter if the file is closed after I open it or remains open.  Seems to initialize something that my script needs.

I don't know what's happening.  I started Fusion fresh and without doing anything else ran your script and it successfully imported my STEP file.  Can you send me your STEP file just in case it is file specific?  You can either post it here or send it to [email protected]

STEP file attached.

I still don't think I'm seeing the same problem you're having.  I did find something that caught me.  I was using the standard backslash as the folder delimiter, i.e. "C:\Temp\Test.STEP" and it was failing saying the file doesn't exist.  If I use forward slash, "C:/Temp/Test.STEP" or double backslash, "C:\\Temp\\Test.STEP", then it works ok.  Can you check the filename that you're building to see if that might be a problem.  Otherwise I'm not sure what else to try.
