Hello dear Experts,

I have performed several operations to create a part with an inner cavity in Inspire 2024.1, as shown in the following image:

However, when I import the model into Simlab 2024.1, the inner cavity does not appear:

I have tried all CAD extension (iges, parasolid, step, etc). What should I do?

Thanks in advance.

Best regards,

Francisco

PD: I have attached the Inspire model.

    When you subtract a solid body from a PolyNurb created in Inspire, it converts your part to a Meshed STL body. You need to export PolyNurb and import it into Inspire before the final subtraction. This will not convert the final model into a meshed body and will keep it as a solid.

    Hello Francisco,

    Seems like your CAD is STL file. When you are trying perform CAD operations in Inspire, it is saving the steps in Inspire Native but not recognizing in export. If you are exporting as Parasolid or step, it will not show in SimLab. Try exporting in STL then import in Simlab to see the Model as you expect. See attached image.

    I have seen this before where inspire "thinks" a PN part is triangles.

    I rewound the history and exported the PN part as parasolid then re-imported and used for the boolean subtraction. Worked as expected.

    Files attached fyi.
