[Bug] Unable to modify text of a sketchText created manually with negative angle

[JeromeBriot]

Hello,

1) Open a new document

2) Add a text with negative angle in a sketch 

3) Run the script below

import adsk.core, traceback # pylint: disable=import-error

def run(context):
    ui = None
    try:
        app = adsk.core.Application.get()
        ui  = app.userInterface

        design = app.activeProduct

        rootComp = design.rootComponent

        sketches = rootComp.sketches
        sketch = sketches.item(0)
        sketchText = sketch.sketchTexts.item(0)

        sketchText.text = 'new text'

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

It returns the error: "Invalid input angle".

Thank you.

I hit the exact same problem today.

What's worse, is that I cannot make the angle positive in the script (e.g. going from -pi/2 to +3/2*pi), as all attempts to assign to an angle fails if the initial value is negative.

sketch_text.angle
-3.141592653589793
sketch_text.angle = 2*math.pi - sketch_text.angle
RuntimeError: 3 : invalid input angle
sketch_text.angle=0
RuntimeError: 3 : invalid input angle
sketch_text.angle=1
RuntimeError: 3 : invalid input angle
sketch_text.angle=math.pi/2
RuntimeError: 3 : invalid input angle
sketch_text.angle=-math.pi/2

Also, 2nd bug, I have also had text flip when I assigned text to it. Unfortunately, I doubted myself and I don't have an reproducable example at the moment. edit: Likely this: https://forums.autodesk.com/t5/fusion-360-api-and-scripts/sketchtext-object/m-p/8562981

And an annoyance: If the sketch text has an angle of -180*, setting it to 180* in the GUI just reverts to -180*. I had to set another (positive) angle in-between.

Hi Mr.JeromeBriot,

Negativity is not allowed!!!

Be always positive, there are snares in F360 to check a sentiment of the User.

In order to avoid consequences, use:

Positivity = 360 - Negativity

Hi @MichaelT_123 , the problem is that it is very easy for a user to create a text with a negative angle. Just drag to rotate the text correctly and Fusion can input a negative value.

Hi Mr ThomasA88

I agree, ....

This is one of some other instances where TF360 frivolously breaks basic mathematical/algebraic/topological rules.

Disallowing minus sign (ASCII 45 or Alt+45 or hyphen or just dash) ... can't be called other than the abhorrent dictatorship, ... as the result we CADeople suffer and resort to writing unnecessary silly replays 🙄.

For you attention here is the another case.

A small update on this. It seems the user can only set a negative angle the first time the text dialog is opened. If they set a positive angle when they first create the text, it seems that they can never set a negative angle.

Unfortunately, I have not found any way to force Fusion to do this recalculation/fix, but twiddling with other SketchText attributes. The "Compute All" command does not affect this either.

I don't know if this is a recent change. I'm using Fusion 360 v2.0.9006.

This seems to have been fixed in v 2.0.9142.
