External surface extraction for Assembly.

[randomdrafter]

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]

Hello randomdrafter,

Follow these steps:
[ol 1]
[li]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).[/li]
[li]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).[/li]
[li]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.[/li]
[li]Copy the extracted shell into a new *.CATPart using Copy -> Paste Special... -> As Result (more about this can be found here_4).[/li]
[li]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).[/li]
[/ol]

Hope this helps,
Best of luck!

TibiX , Thanks for the reply I will try this tomorrow.

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.

Since you have a STEP file you can skip the first two steps...
