Parameter I/O Add-in Question

joecamisa — Wed, 28 Apr 2021 01:01:59 GMT

I am using the Parameter I/O add-in with great success. This is an excellent add-in! This add-in has enabled me to create a model with 500 dimensions driven by a single User Parameter. My question: is there anyway to speed the import process? Import takes about 25 minutes for a model with 500 dimensions. Seems like the model is being updated for each parameter imported - is there a way to hold off on Compute until all parameters have been imported?

Thanks for any guidance.

Hi @joecamisa .

I haven't used the Parameter I/O Add-in, but if you can modify it, changing the timeline.markerPosition Property might help.

https://help.autodesk.com/view/fusion360/ENU/?guid=GUID-d0cede26-e905-45b4-b30d-8f244670c1f7

I drew a circle on the sketch to create a diameter constraint and ran the following script

# Fusion360API Python script import adsk.core, adsk.fusion, traceback import time def run(context): ui = None try: global _app, _ui app = adsk.core.Application.get() ui = app.userInterface des :adsk.fusion.Design = app.activeProduct prm = des.allParameters.itemByName('d1') # As it is sw = stopwatch() sw.start() test(prm) print(f'As it is:{sw.lap()}') # Move MarkerPosition sw.start() tl = des.timeline markerPos = tl.markerPosition tl.moveToBeginning() test(prm) tl.markerPosition = markerPos print(f'Move MarkerPosition:{sw.lap()}') except: if ui: ui.messageBox('Failed:\n{}'.format(traceback.format_exc())) def test(prm, count = 500): for v in range(count): prm.value = v class stopwatch(): def __init__(self): self.t = 0 def start(self): self.t = time.time() def lap(self) -> str: return '{:.3f}'.format(time.time() - self.t)

Here are the results.

As it is:45.503 Move MarkerPosition:29.732

I have a feeling that more complex data would have a bigger effect.

I think you can do what @kandennti suggests without changing any code. Just move the timeline marker to the beginning of the timeline before you run the Parameter I/O command, run the command, and then move the marker back to where it was.

Hello @kandennti and @BrianEkins

Your suggestions have worked! I found that I needed to move the timeline marker back to just AFTER the sketch with the dimensions to be exported, made proportional in a spreadsheet and reimported as User Parameter based (fx) dimensions. The import took less than one minute vs 20 minutes without moving the timeline marker.

This is a great help for my work process and is GREATLY APPREACIATED.

Thank you both.

I hope soon I will learn enough to contribute guidance as you both have.
