Fusion 360 "Python" Script - Flat Pattern & Export To Dxf

isocam — Mon, 14 Aug 2023 14:07:16 GMT

Can anybody help?

Is it possible, using a Fusion 360 "Python" Script to automatically "Flat Pattern" & Export a "dxf" file from a "sheet metal" model?

If it is, can somebody post the script file required to do this?

Many thanks in advance!

Darren

Hi @isocam -San.

I have exported a DXF of a flat pattern in a previously published add-in.

@isocam -San.

The execution condition is that the root component must have a sheet metal body.

# Fusion360API Python script import traceback import adsk.core as core import adsk.fusion as fusion import pathlib def run(context): ui: core.UserInterface = None try: app: core.Application = core.Application.get() ui = app.userInterface des: fusion.Design = app.activeProduct root: fusion.Component = des.rootComponent # get sheetmetal bodies sheetBodies = [b for b in root.bRepBodies if b.isSheetMetal] # get sheetmetal large face flatFaces = [f for f in sheetBodies[0].faces if f.geometry.objectType == core.Plane.classType()] targetFace: fusion.BRepFace = max(flatFaces, key=lambda f: f.area) # remove flatpattern flat: fusion.FlatPattern = root.flatPattern if flat: flatProd: fusion.FlatPatternProduct = flat.parentComponent.parentDesign flatProd.deleteMe() # create flatpattern flat: fusion.FlatPattern = root.createFlatPattern(targetFace) # export path exportPath = str(pathlib.Path("C:/temp") / f"{flat.name}.dxf") # export dxf export_dxf(exportPath, flat) except: if ui: ui.messageBox('Failed:\n{}'.format(traceback.format_exc())) def export_dxf(path: str, flat: fusion.FlatPattern) -> None: app: core.Application = core.Application.get() des: fusion.Design = app.activeProduct expMgr: fusion.ExportManager = des.exportManager dxfOpt: fusion.DXFFlatPatternExportOptions = expMgr.createDXFFlatPatternExportOptions( path, flat, ) expMgr.execute(dxfOpt)

Here's a simple script that checks the active document has a flat pattern and exports it as DXF.

def run(context): app = adsk.core.Application.get() ui = app.userInterface try: flatProduct: adsk.fusion.FlatPatternProduct = app.activeDocument.products.itemByProductType('FlatPatternProductType') if flatProduct is None: ui.messageBox('No flat pattern exists in the active document.') return flat = flatProduct.flatPattern if flat is None: ui.messageBox('No flat pattern exists in the active document.') return filename = 'C:/Temp/Test.dxf' flatExportOptions = flatProduct.exportManager.createDXFFlatPatternExportOptions(filename, flat) if flatProduct.exportManager.execute(flatExportOptions): ui.messageBox(f'Successfully exported flat pattern to: "{filename}"') else: ui.messageBox('Flat pattern export failed.') except: if ui: ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))
