Making a Solid Blade Hollow

[sudhi4cric]

Hello Sir

I have turbine rotor blade designed as per the aerodynamic considerations. The profile i obtained from the company is completely solid, I would like to make it hollow with  a wall  thickess of 5 mm. I tried if with the Shell feature of Inventor, and Since the profile of the blade is in different planes twisted in different angles, the Shell is not working very well. I have tried it with loft with different cross sections, but i am not getting a completely accurate profile. Is there any tool which automatically recognises the outside profile and will make the Inside hollow also in Inventor? I will really appreciate if some one can give a solution from your valuable experiences..

Thanks in advance

Regards

You could start a new part and use the "Derived Component" tool to add the surfaces from the solid part into your new part. Then use the "Thicken/Offset" tool to add thickness to the surfaces.
