Thin wall failure

[Putzola]

HI,
I'm trying to make a thin wall solid in ST1, synch mode. I've created the outside shape of the bottle and I'm trying to remove the interior leaving me with a 1mm thick bottle wall.

There is only 1 face that I can use to create the thin wall, the opening of the bottle, but it fails every time with "failed to offset or delete the face".
The bottle is not a regular round shape.

Also, if I ever manage to create the thin wall is there a way to measure the volume that it can hold?

It's probable that you have a round shape that is close the the 1 mm wall thickness that you want. If so it's sure that the thin wall cannot be created.

For the volume you could go in the traditionnal environment and bring your bottle as a part copy then you could use a boolean operation to have the interior volume.

I hope it helps.

Thanks Patrick.
I understand what you're saying about the boolean operation but I'm not really sure what you mean about a round shape close to 1mm.
I can make the thin wall 0.5mm but no thicker. Is there a way to solve that?

either the rounding will vanish during the operation or an
openeing gets closed. You may upload your part and we can have
a look at it

If you could spare a moment it would be very helpful. I've been fiddling with this for ages and not making much progress at all.

One of the surfaces can not be offset more than .5 mm without collapsing on itself.

An easier method might be to model the inside surfaces first. Close them off so you can find their volume (you might have to make them a solid). Then when the volume is right make the thin wall on the outside. You will still need keep any inside radi larger than the wall thickness.

Thanks HDS.
Was kinda hoping you weren't going to say that but at least I know now
