Extrude or revolved, without unit or substact (SE ST2)

[smermet]

Hi,

After having created a first body,
is there a way to create an other body (extruded or revolved) without unit or substact it?

Thanks.
Best regards.

SE does not support multi-body parts.
You can create solid features that do not intersect, or create surfaces for the second body.

Where would we be without sat-nav?

The question of multi-body parts has been raised before and I can't understand why SE still does not have this feature.
It is often the most sensible way to produce models for castings - create the outer shape as a solid, then seperate bodies for cored areas which can then be subtracted from the outer to form the final casting.

I'm sure I've done what you are after in the past on SE ST2, using the Boolean command under surfacing (drop-down below Replace Face)...

Just tried it and it works fine - create a part model of the casting envelope, create a separate part of the casting core and then part-copy the core model into the envelope model (or part-copy both into a new part model if you prefer).

Click Boolean (under Replace Face on the Surfacing tab), ensure subtract is selected and then select the part copy of the core.

Just make sure you use the axes as a common datum for both parts.

Jon,
that's a way to get round it but I've usually found that I need the casting outer faces as reference to create the cores, so you end up going round in circles.

Okay fair enough - we model our cores separately if using this as the forms do not follow too closely.

Not 100% sure if this would work as I haven't tried it, but I can see no reason why it shouldn't...

Model the core then part copy it in to a new model and thicken/refernce the core to form the outer envelope of the casting.
Part copy both of these two models (i.e. the original core model and it's relative envelope model) into a third part file and perform the Boolean operation leaving a casting where the outer envelope references the inner core.
This should update when any changes are made and of course can also be done the other way round (i.e. envelope first) if you wish.
