I'm trying to import Inventor .IPT files into Solidworks, including the features. 

For most parts this works okay, but for some parts the pop-up where I can choose between importing features or only the solid body doesn't show up. In that case we only get the solid body. Does anybody know why this pop-up doesn't show for some specific parts?

I'm using Solidworks 2025 and Inventor 2024 for this.
