Save Sketch To DWG File Using A Python Script

[isocam]

Can anybody help???

I have created a simple sketch, for testing purposes, and extruded it.

The sketch will always be called "Sketch1" consisting of Lines, Arcs and Circles.

I want to be able to automatically save the sketch as a 2D AutoCAD "Dwg" file, when I run a Python script.

I do not want to manually select the sketch first as the sketch will always be called "Sketch1".

Can this be done?

Many thanks in advance!

Hi @isocam .

You cannot export a sketch as a DWG file.
It is the same with the GUI.

Here is a sample of exporting as a DXF file instead.

# Fusion360API Python script
import adsk.core, adsk.fusion, traceback

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 = root.sketches.itemByName('Sketch1')
        if not skt:
            return

        exportDXF_Desktop(skt, 'hoge.dxf')


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


def exportDXF_Desktop(
    skt: adsk.fusion.Sketch,
    filename: str, 
    ):

    import os
    desktop_dir = os.path.expanduser('~/Desktop')

    import pathlib
    path = pathlib.Path(desktop_dir, filename)

    skt.saveAsDXF(str(path))
