How to correctly use the importManager to import an IGES file

Joshua.mursic — Wed, 22 Mar 2023 21:18:39 GMT

import adsk.core app = adsk.core.Application.get() product = app.activeProduct design = adsk.fusion.Design.cast(product) root = design.rootComponent for die in dies: id = die[0] boundary = die[1] boundaryName = f'{boundary.split("/")[len(boundary.split("/"))-1].split(".")[0]}:1' insertionAngle = die[2] iges = app.importManager.createIGESImportOptions(boundary) iges.isViewFit = False app.importManager.importToTarget(iges, root) newBoundary = design.activeComponent.occurrences.itemByName(boundaryName)

I am trying to import an IGES file into my design. It is creating a new occurrence, but the occurrence is empty.

Am I using this function incorrectly? I am not sure what I am doing wrong.

Thanks

Hi @Joshua.mursic .

I would guess from the name "boundary" that the Iges file contains only curves.
Fusion360 only imports surface data from Iges files.

yes you are correct, I am trying to import a 3D sketch of curves. Is this possible?

@Joshua.mursic .

I have created and published an add-in to import Iges/Step/Brep curves.

https://github.com/kantoku-code/Fusion360_Curve3D_Doorway

The way it works is that I read the files via software (like a CAD without a screen) published by another Japanese person, extract only the necessary information, and draw the curves one by one on the sketch.
