Appearance Bug??

[brad.bylls]

I have some code from an add-in I'm working on that worked several months ago.

    # Set the spring color

    fusionMaterials = _app.materialLibraries.itemByName('Fusion 360 Appearance Library')

    appear = fusionMaterials.appearances.itemByName('Powder Coat (Blue)')

    if strColor == 'Blue':

        blueColor = design.appearances.addByCopy(appear, 'BlueColor')  <<< Line 290

        colorProp = adsk.core.ColorProperty.cast(blueColor.appearanceProperties.itemByName('Color'))

        colorProp.value = adsk.core.Color.create(0, 0, 255, 0)

        bd.appearance = blueColor

    elif strColor == 'Red':  

        redColor = design.appearances.addByCopy(appear, 'RedColor')

        colorProp = adsk.core.ColorProperty.cast(redColor.appearanceProperties.itemByName('Color'))

        colorProp.value = adsk.core.Color.create(255, 0, 0, 0)

        bd.appearance = redColor

    elif strColor == 'Gold':

        goldColor = design.appearances.addByCopy(appear, 'GoldColor')

        colorProp = adsk.core.ColorProperty.cast(goldColor.appearanceProperties.itemByName('Color'))

        colorProp.value = adsk.core.Color.create(204, 204, 0, 0)

        bd.appearance = goldColor

    else:

        greenColor = design.appearances.addByCopy(appear, 'GreenColor')

        colorProp = adsk.core.ColorProperty.cast(greenColor.appearanceProperties.itemByName('Color'))

        colorProp.value = adsk.core.Color.create(0, 153, 0, 0)

        bd.appearance = greenColor

I am now revising the code and I get this error message:

Has something changed in the API or is it my code?

Thanks in advance for any help.

Hi @brad.bylls .

Isn't there already an appearance with the same name ('BlueColor') in design.apppearances?

[brad.bylls]

kandennti,

I only know of this:

     fusionMaterials.appearances.itemByName('Powder Coat (Blue)')

I will change the name to BluColor and see what happens.

Thanks.

Thanks kandennti.

That worked.

Just strange that it worked before and not now.

[brad.bylls]

Okay.

I changed the names of the colors.

    # Set the spring color

    fusionMaterials = _app.materialLibraries.itemByName('Fusion 360 Appearance Library')

    appear = fusionMaterials.appearances.itemByName('Powder Coat (Blue)')

    if strColr == 'Blue':

        blueColr = design.appearances.addByCopy(appear, 'BlueColr')

        colorProp = adsk.core.ColorProperty.cast(blueColr.appearanceProperties.itemByName('Color'))

        colorProp.value = adsk.core.Color.create(0, 0, 255, 0)

        bd.appearance = blueColr

    elif strColr == 'Red':  

        redColr = design.appearances.addByCopy(appear, 'RedColr')

        colorProp = adsk.core.ColorProperty.cast(redColr.appearanceProperties.itemByName('Color'))

        colorProp.value = adsk.core.Color.create(255, 0, 0, 0)

        bd.appearance = redColr

    elif strColr == 'Gold':

        goldColr = design.appearances.addByCopy(appear, 'GoldColr')

        colorProp = adsk.core.ColorProperty.cast(goldColr.appearanceProperties.itemByName('Color'))

        colorProp.value = adsk.core.Color.create(204, 204, 0, 0)

        bd.appearance = goldColr

    else:

        greenColr = design.appearances.addByCopy(appear, 'GreenColr')

        colorProp = adsk.core.ColorProperty.cast(greenColr.appearanceProperties.itemByName('Color'))

        colorProp.value = adsk.core.Color.create(0, 153, 0, 0)

        bd.appearance = greenColr

But then I found out that if I run the add-in script a second time, I get the same message.

I think what I need to do is delete that color at the end of the script so if it runs again I won't get the message.

Do you know how to delete a color?

Thank you.

I did some testing a while ago and found some problems with appearances.  Autodesk is aware of the problems.  So, it may not be your code but a bug you've run into.

[brad.bylls]

Thanks Brian.

Just did some if . . . else to get around the problem.
