Create cavity using Catia Surface file

I have received an IGES file for a model originally created in Catia.
When opened, Solidworks creates a number of surfaces. I want to
create a cavity from this model. Normally, when I receive a solid
model I can bring it into an assembly and then use the cavity function
to substract this from my cavity block.

Is there anything I can to do to achieve the same results with the
surface model I have received.

 

Gavin,

Did it come frome Catia V4 or V5 ?? There's a big difference.

If it's Ver 5, have them send you a STEP file.

If it's Ver 4, you'll probably have to use a translation service bureau, or
a third party add in like "Format Works"


Regards

Gavin,
Did you try "Import Diagnosis" to see if that will close up the gaps and
knit to solid?

Hi there,

Use the check tool (or import diagnostics) to find out where the holes are -
hopefully there won't be many. Then you can use surface features, such as
fill surface, to patch the holes and finally knit into a solid. From there
you should be able to create your cavity as normal.
