Hollow Settings (hollowing and extrusion)

tom_mort

I have a rectangular extrusion and want to hollow it.  I'm trying to figure out the settings on the hollow tool control.

I need specific inside dimensions and I see where I can set the thickness of the walls and I read that I can toggle between having the wall thicknesses subtracted or added to the original  dimensions of the triangle.

I don't recall now where or what this toggle was, but, I think it was on arrow.  I don't really see any changes on my drawing or a way to dispaly what the inside dimensions actually turned out to be.

Can someone clarify this a little?

TIA

Can you make your document public so we can see what you are trying to do? 

If you cant, try modeling the internal volume of your part and use a Boolean subtract. Or use the Transform -> Scale uniformly option and Boolean the results as desired.

I recognize this screen with the shell thickness setting and the opposite direction arrow, but, that is sort of what I am asking.  I don't know what happens if I toggle the arrow or a way to see what the actual dimensions will be on the inside of the shell.

Does the setting above mean if I set my extrusion to have dimensions of  x + 2*2.5 by y + 2*2.5 that the inside dimensions of the shell will be x by y?

Is there some way to show a view of the part where all the dimensions are automatically labeled a visible?

@tom_mort The arrow literally flips the direction of the shell - default is to create a hollow part, so if your sketch is x wide, y high, the outside dimensions will stay x by y. Flip the arrow to remove the extrude volume and add material to the outside. The interior is now x by y and the outside is x+5 by y+5. If you right click the sketch in the feature list you can select "show dimensions", but they are only temporary graphics.

OK, that clarifies things.  Thanks

You can set notification settings in the Account Options / Preferences - gear icon in upper right corner.

Thanks, I found it later. I was expecting to see it at the bottom of the form I posted.
