Creating parameters with script problem

[brad.bylls]

My first try at scripting so please bear with me.

I have gone through the forum and tried lots of different examples, but nothing seem to work.

I am reading a csv file and then trying to create some user parameters.

I am reading the file ok and get the correct values, but when I try to create the parameters, BOOM:

This is the code in question:

cnt = 0

file = open('C:/Users/bradb/AppData/Roaming/Autodesk/Autodesk Fusion 360/API/Scripts/SHCStest/SHCS-IMPERIAL.csv')

for line in file:

   # Get the values from the csv file.

    pieces = line.split(',')

    if pieces[0] == '1/2-13':

        ScrewDiameter = pieces[1]

        HeadDiameter = pieces[2]

        HexSize = pieces[4]

        TapDrill = pieces[5]

        HeadFillet = pieces[6]            

        # Create user parameters

        # Set the parameters.

        ScrewDiameterParam = design.userParameters

        ScrewDiameterParam.add('ScrewDiameter', ScrewDiameter, 'in', '')

Being new I am not sure how to track down the proper syntax, arguments, etc  in the documentation.

Any help is appreciated.

Thank you in advance.

Assuming that the ScrewDiameter is a number, you need to use ValueInput.createByReal to create the value that you use to save the parameter. You can’t store the number directly.

Something like:

ScrewDiameterParam.add('ScrewDiameter', ValueInput.createByReal(ScrewDiameter), 'in', '')

Here’s some code that I’m using for something similar.

There was supposed to be a picture showing the error message. Here is the error:

in method 'UserParameters_add', argument 3 of type 'adsk::core::Ptr< adsk::core::ValueInput > const &'

File "c:\users\bradb\appdata\local\autodesk\webdeploy\production\d2d901e2ef5ae5c384b4ac001a48c4e37589dc43\...", line 31754, in add return _fusion.UserParameters_add(self, *args) File "c:\Users\bradb\AppData\Roaming\Autodesk\Autodesk Fusion 360\API\Scripts\SHCStest\SHCStest.py", line 30, in <module> ScrewDiameterParam.add('ScrewDiameter', ScrewDiameter, 'in', '')

Thank you.

I tried it, but an error message said 'ValueInput not created'

I also looked at your code and found nothing similar.

I am a newbe and must be missing something.

I wasn't thinking when I replied to you. I'm guessing that when you are reading the file, the ScrewDiameter is being read as a string, in which case, you need to use ValueInput.createByString instead of createByReal.

Try this:

cnt = 0
file = open('C:/Users/bradb/AppData/Roaming/Autodesk/Autodesk Fusion 360/API/Scripts/SHCStest/SHCS-IMPERIAL.csv')
for line in file:
   # Get the values from the csv file.
    pieces = line.split(',')

    if pieces[0] == '1/2-13':
        ScrewDiameter = pieces[1]
        HeadDiameter = pieces[2]
        HexSize = pieces[4]
        TapDrill = pieces[5]
        HeadFillet = pieces[6]            
        
        # Create user parameters
        # Set the parameters.

        ScrewDiameterParam = design.userParameters
        ScrewDiameterParam.add('ScrewDiameter', ValueInput.createByString(ScrewDiameter), 'in', '')

That didn't work, but I finally tracked down some code that did.

Thank you for the input.

Since this was the closest answer to a question I struggled with I thought I would add to it.  The api example reading from the CSV works if you want to do that, but I was wanting to just create a parameter directly.  Without getting into user inputs here is the basic code.

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

def run(context):
    ui = None
    try:
        app = adsk.core.Application.get()
        ui  = app.userInterface
        design = adsk.fusion.Design.cast(app.activeProduct)

        #retParam = design.userParameters.itemByName('Size')
        #ui.messageBox(retParam.expression)
        widthValueInput = 5.0
        inputUnits = 'mm'
        widthValuePass = widthValueInput / 10
        widthValue = adsk.core.ValueInput.createByReal(widthValuePass)
        design.userParameters.add('width',widthValue,inputUnits,'')

    except:
        if ui:
            ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

  I left the retParam in there commented out because I used that to find if a parameter was in the design and then I returned the expression from that back to the user.  I thought it might be helpful for anyone trying to do this.  I did leave an input value(even though the code isn't prompting the user) and the widthValuePass is converting it from cm to mm before using ValueInput.createByReal.

Hope it helps someone!

Thanks for the input.

This is what I ended up doing.

# Create user parameters
	userParams = des.userParameters
	MOLDparam = userParams.add('Mold_Exists', adsk.core.ValueInput.createByString('Exists'), '', 'Exists')
	TCPparam = userParams.add('TCP_thickness', adsk.core.ValueInput.createByReal(numPlateTCPthickness), 'in', 'TCP Plate Thickness')
	Aparam = userParams.add('A_thickness', adsk.core.ValueInput.createByReal(numPlateAthickness), 'in', 'A Plate Thickness')

 And then used this to update the model parameters using the User Parameters

# Modify model parameters
	# TCP plate
	extent_1 = plateTCPext.extentOne
	extent_2 = plateTCPext.extentTwo
	distanceMP_1 = extent_1.distance
	distanceMP_2 = extent_2.distance
	distanceMP_1.expression = 'TCP_thickness + A_thickness'
	distanceMP_2.expression = 'A_thickness * -1'
