Sketch with text via API not exporting text but will manually

marylou.forsyth — Tue, 21 Mar 2023 15:40:10 GMT

Good day programmers! I am asking for help as I am just not seeing what steps I am missing. Please let me give the background. We open a model via API script, we read in new parameters to update the model to, and update the model. All processing is done via the API script. My customer has requested a specific type of processing done, where the model has a few sketches, to delete all sketches not named in a list, and export the model as a DXF. The logic I wrote to address this can be identified as the DXF_Type_BPB (for it needs to be a DXF export with only the Body, Pen_lines and Bend_Lines {BPB})

The logic goes through and removes the sketches not needed, then exports out a file with just the pen-line (so I can verify in testing which actually looks great) and then exports out the body and the one sketch Pen_Line. My problem is when the second export happens, I don't see the text.

The manual export (fullPath + sketch.name + 'dxf') which is looking ok to me appears as this:

and at the top you can see the text data 'HV something'.

The export with the body, Pen_line though only creates this as I must be missing something major:

Here is the code (please ignore the section that says else: DXF_Type_BPB == False ) AND please forgive the horrible loop where I flush out the un-needed sketches, it will be re-written.

I thought this line was going to give what I needed but sadly no:

[sketchEntities.add(ent) for ent in sketch.sketchTexts]

One more thing, there is logic to adjust the scaling but thats been working fine.

#we call this right before the code in question --> : updateParametricModel(tag,value,userParams,False)

else: # its a punch so export the drawing scaled correctly
global DXF_Type_BPB
# flag if problem of no cam found when making a DXF
Stop_it = False

fullPath = os.path.join(folder, order)

# write the merged file
master.saveAsDXF(fullPath + '.dxf')
msg = '!! DXF file has been written !!'
DFX_Generated = True
#print(msg)
futil.log(msg)

I will drag and drop as this is hard to read.

Thank you for your time and assistance, I have looked and tried so many different things but I just can't resolve this.

Hi @marylou.forsyth .

If you want to include your code in the forum, this is a good way to display it.

When I tried, the project/include method was not available for SketchText objects.

Therefore, I created a sample that explodes and then projects the data.

# Fusion360API Python script import traceback import adsk.core as core import adsk.fusion as fusion def run(context): ui = core.UserInterface.cast(None) try: app: core.Application = core.Application.get() ui = app.userInterface des: fusion.Design = app.activeProduct root: fusion.Component = des.rootComponent path = r'C:\temp\test.dxf' targetSketchNames = ['PEN_LINE','BEND_LINE'] try: app.executeTextCommand(u'Transaction.Start export_project_sketch') export_project_sketch( targetSketchNames, root.xYConstructionPlane, path, ) except: pass finally: app.executeTextCommand(u'Transaction.Abort') ui.messageBox('Done') except: if ui: ui.messageBox('Failed:\n{}'.format(traceback.format_exc())) def export_project_sketch( targetSketchNames: list, supportPlane: fusion.ConstructionPlane, path: str, ) -> None: def get_sketch_entities( skt: fusion.Sketch, ) -> list: lst = [c for c in skt.sketchCurves] lst.extend([p for p in skt.sketchPoints]) return lst def explode_sketchTexts( skt: fusion.Sketch, ) -> None: skt.isComputeDeferred = True sktTxtLst = [t for t in skt.sketchTexts] [t.explode() for t in sktTxtLst] skt.isComputeDeferred = False # ******* app: core.Application = core.Application.get() des: fusion.Design = app.activeProduct root: fusion.Component = des.rootComponent sktLst = [skt for skt in root.sketches if skt.name.upper() in targetSketchNames] if len(sktLst) < 1: return [explode_sketchTexts(skt) for skt in sktLst] sktEnts = [] [sktEnts.extend(get_sketch_entities(skt)) for skt in sktLst] if len(sktEnts) < 1: return sketchEntities: core.ObjectCollection = core.ObjectCollection.create() [sketchEntities.add(e) for e in sktEnts] master: fusion.Sketch = root.sketches.add(supportPlane) master.name = 'Master' master.project(sketchEntities) master.saveAsDXF(path)

Since it would be inconvenient if the original data were left exploded, we used a transaction of text commands to return the data to the state before processing.
However, since explode is very time-consuming, I do not think it will be useful in practice.

You are a wonder to behold! You have nailed the issue, I have been working on this and you just brought it to a resolution, bless you!! Yes, so right you are I spoke with the developers and they will explode the text in sketches so the API will not have too. Would not have gotten here without your help, thank you!!
