Exclude Bolts

Hello everyone,Could you kindly tell me how to exclude the bolts of a flanged coupling on E3D? In order not to show them on the material list and consequently in the general mto​.Is there a flange or gasket attribute that needs to be set?​ ​T​hanks.

If you are using "new" bolt method, you can try setting BSEL attribute of flanged component to a dummy value. i.e 'N/A'
