External surface extraction for Assembly.
External surface extraction for Assembly.
(OP)
Any one knows how to extract external surfaces in a assembly.
My requiremnt is to create a Dumb solid for a Engine. [Dont want to show internal features,especially Bore and other details]

RE: External surface extraction for Assembly.
Follow these steps:
- First you have to create a single part from your assembly. When you are in Assembly Design workbench go to Tools -> Generate CATPart from Product... (more about this can be found here_1).
- If everything went well, you should have a CATPart with several bodies. You will need to combine (add) them in Part Design workbench using Boolean operations (more about this can be found here_2).
- Now go to Generative Shape Design workbench and use the Extract feature (more about this can be found here_3). Click on any face of the solid and use Propagation type: Point continuity. You should now have an empty shell of the solid.
- Copy the extracted shell into a new *.CATPart using Copy -> Paste Special... -> As Result (more about this can be found here_4).
- And now you can close the extracted shell to obtain the featureless solid using the Close Surface feature in Part Design workbench (more about this can be found here_5).
Hope this helps,Best of luck!

Currently I have a single file of entire engine as mentioned in 1st step.
will let you know after trying other steps, as this is a big engine I guess it may take lot of time.
