Please help fix Parameter I/O AddIn. Not updating parameters.

[olegkar]

Recent Fusion 360 update changed something and now AddIn does not work correctly.

It reads parameters from file, writes them to file. But It can not update them if they already exist.

I guess the problem is in those lines:

def readParametersFromFile(filePath😞

    app = adsk.core.Application.get()

    design = app.activeProduct

    ui  = app.userInterface

    try:

        paramsList = []

        for oParam in design.allParameters:

            paramsList.append(oParam.name) 

paramsList should get the names of all parameters in the current model, but it appears to be empty.

I guess in the October update this design.allParameters has been changed. And the question is how to get the names of parameters now?

Please help! My project relies on this AddIn a lot

Yes, I also have this problem since yesterday's update. I don't have the skills to sort this one...

Can we please have a grown up to help?

Nothing specific to parameters has changed but there's a tool that's used to build the API that was updated to a newer version and I suspect this is a result of that. There's a problem with the original add-in that must have been there since the beginning but it wasn't being caught.  It was trying to set the value of a read-only property.  Now that's causing a failure, which it should have been doing all along.

I'll see if I can track down who's now responsible for this add-in and get the version on the App Store updated.  In the meantime you can edit the version you installed from the store.  To fix it, comment or delete line 220 in ParameterIO.py.

paramInModel.unit = unitOfParam

It's not possible to change the unit type of an existing parameter and that's what that line is attempting to do.

Thanks BrianEkins - commenting out line 220 in ParameterIO.py has solved this problem for me

Good work!

Parameter I/O add-in is updated on App Store with fix. Please try after updating to new version. Thanks.

The official app store version is now installed and it also works great. Thanks

Just a note and a word of warning.  I'm reasonably sure this hasn't been fixed.  

If you have parameters that refer to other parameters (eg innerWidth = width - 2*wallThickness), importing the parameter file will fail IF the referred to parameters occur AFTER the parameter that references them

innerWidth = width - 2*wallThickness
width = 24
wallThickness = .75  #this order will fail!

the fix for this is to use an editor to swap the order to ensure consistency:

width = 24
wallThickness = .75
innerWidth = width - 2*wallThickness  #this order will work

  I hope that helps someone.
