Importing Solids

[OceanDesigner]

I have created a solid model of a boat hull in Rhinoceros. I have tried and tried to get it into AutoCAD as a solid and I am really unsatisfied with the result. It appears the only way to bring in a solid is by importing the model in ACIS format. ACIS really seems to make a mess of the geometry though - the parameterization is seems to have no rational organization and in some cases ACIS even adds extra details that are not in the original model. I am in search of any way to get a solid boat hull model into AutoCAD. I am willing to bring in as IGES or similar and regenerate the solid in AutoCAD if that is possible.

Thanks, Jeff

Hi Jeff,

ACIS is about the only way to bring in a solid into AutoCAD you can do IGES but if I remember right it gets converted into a surface mesh. If you have the option in Rhinoceros to control what version of ACIS is outputs, you might try setting it to a lower version. AutoCAD 2002 is only version 4.0. Newer versions of AutoCAD may use a higher vesion but you may try changing the setting to 1.5, as AutoCAD doesn't know what to do with the construction geometry.

If that's not an option you can try opening it up in a package like SolidWorks and doing some clean up there (I know SolidWorks can control what version of ACIS it can output).
