Bug: Setting SketchText properties resets text height since v. 2.0.10244

thomasa88 — Tue, 01 Jun 2021 19:42:10 GMT

Fusion 360 v. 2.0.10244 breaks the sketch text API. Changing the any property of a SketchText results in the height of the text being reset to 1.0 (cm).

This means that the workaround of getting the height first, setting properties, and the restoring the height, does not work.

In the GUI, create a new document. Create a sketch with a sketch text. Set the sketch text height to 20 mm.

In the Python console (Ctrl+Alt+C -> py), execute the following lines:

app = adsk.core.Application.get() t = app.activeProduct.rootComponent.sketches[0].sketchTexts[0] t.height 3.0 t.text="new" t.height 1.0 t.height=3.0 t.height 1.0

This breaks my ParametricText add-in \o/. Issue: https://github.com/thomasa88/ParametricText/issues/21

I think you broke something similar with text spacing in December 2020. https://forums.autodesk.com/t5/fusion-360-api-and-scripts/cannot-select-shx-fonts-on-sketchtext-object/m-p/9923259/highlight/true#M12082

A possible workaround could be to set the parameter that is now associated with the text height.

However, if it can't be looked up by parameter name, we will have to do a search through all parameters, which I think will lead to a performance hit. Also, I cannot find any property in ModelParameter that has a matching property in SketchText (my first guess was role (Text1-Height), but we cannot know what text is Text1).

d = app.activeProduct p=d.allParameters.itemByName('d1') p.value 1.0 p.value=3.0 p.name d1 p.component <adsk.fusion.Component; proxy of <Swig Object of type 'adsk::core::Ptr< adsk::fusion::Component > *' at 0x0000024506A9BDE0> > p.role Text1-Height t.height 3.0

Hi @thomasa88 .

I found a way to access the Sketch Text Height Parameter.

# Fusion360API Python script import adsk.core, adsk.fusion, traceback import json def run(context): ui = adsk.core.UserInterface.cast(None) try: app :adsk.fusion.Application = adsk.core.Application.get() ui = app.userInterface des :adsk.fusion.Design = app.activeProduct root :adsk.fusion.Component = des.rootComponent skt :adsk.fusion.Sketch = root.sketches[0] txt = skt.sketchTexts[0] # get Height Parameter prm = getTextHeightParameter(txt) # resize prm.value = 2 except: if ui: ui.messageBox('Failed:\n{}'.format(traceback.format_exc())) def getTextHeightParameter( txt :adsk.fusion.SketchText ) -> adsk.fusion.ModelParameter: def getProp(id :int) -> dict: return json.loads(app.executeTextCommand(u'PEntity.Properties {}'.format(id))) app :adsk.fusion.Application = adsk.core.Application.get() ui = app.userInterface sels :adsk.core.Selections = ui.activeSelections sels.clear() sels.add(txt) # get ID txtId = int(app.executeTextCommand(u'Selections.List').split(':')[-1]) sels.clear() # get parameter Name textExProp = getProp(txtId) dcDoubleParameterProp = getProp(textExProp['textInfo']['heightDCParam']['entityId']) parameterProp = getProp(dcDoubleParameterProp['parameter']['entityId']) prmName = parameterProp['userName'] # get sketch text Height Parameter prms :adsk.fusion.ParameterList = txt.parentSketch.parentComponent.parentDesign.allParameters return prms.itemByName(prmName)

It is faster than this method.

Thanks @kandennti , you are the master of TextCommands.

However, I believe the TextCommands in themselves being a performance hit (haven't measured though) and the select+unselect procedure is not acceptable for my add-in.

I tried digging for the entityId using the regular API, but I did not find a match (entityId is a number while entityToken is something base64-encoded).

I first thought that the entityToken for the parameter and the SketchText was the same (what!), but it turns out that all objects' entity tokens look very similar - but differ at the end.. (Also, I know that entityTokens are unstable and should no be compared)

Unfortunately, I have not found a way to get the entityId without using selection.

As for entityTokens, we users will still not be able to understand them in the future.

The most desirable thing would be for the bug to be fixed.

Latest idea!

1. Save all .value from sketch_text.parentSketch.parentComponent.modelParameters.
2. Change the sketch.
3. Loop modelParameters again. If a value does not match the original value, restore it.
4. Tada!...

It seems to work, but I was hoping to be able to detect if the bug was in effect so that I could turn off this potentially heavy workaround if the bug was not there.

I thought that I could let my workaround only apply if SketchText.height != 1.0 and then if the correction did not have to correct any values --> disable the workaround.

However, SketchText.height value seems to be trash, so I can only tell if I needed to do a fix by correcting the value (keep the workaround on), but not if a fix is no longer needed, as I cannot see if the user used a text with a height that is affected by the bug (i.e. the user has a text with height = 1.0 cm). 😞

I know that it is a double, but come on.. (height is set to 20mm in the GUI):

sketch_text.height
0.9999999999999996

Edit:

To check: What happens if a user has assigned an expression? Will we overwrite it? Will the expression itself "protect" the height? (Likely, it will just be reset)

Hi Mr ThomasA88,

You seem to be quite desperate with the issue.😓

Well,... I do understand.

I have been shaken by textObject development in F360 quite a few times. So if you are interested, it is not difficult to find out why&where&how.😉

In your current case (under the condition that textOnPath is not on your agenda), find an old file (~> one year old) with textObject in it and run your height changing script on it. There is a good chance that it will work.

Regards

MichaelT

Hi MichaelT, I need my add-in to work for every condition, as ParametricText is a general add-in, so using an old document is unfortunately a viable solution.

For anyone that's interested, my current workaround is done in two steps:

Check if Fusion 360 is affected by the bug
1. Store parent component model parameters' expressions
2. Change text height of sketch to a value not close to 1.0
3. Read back the value. Is it close to 1.0 (Fusion sometimes sets it to 0.99999996), then the bug is present.
4. Loop through the model parameters and restore the one that was changed
If the bug is present:
1. Store parent component model parameters' expressions
2. Change the sketch text
3. Loop through the model parameters and restore the one that was changed

EDIT: And I don't want anyone to mark this as the solution of this issue, as it is only a workaround!

ParametricText users are now reporting problems with the workaround for the bug. https://github.com/thomasa88/ParametricText/issues/46

A quick test with the code in the original post in this forum thread indicates that the bug might now be gone. Can anyone else confirm?

I tested the code in the first post in this thread, and it changes the text without changing the size. The size remains constant.
