Hollow Settings (hollowing and extrusion)

tom_morttom_mort Member Posts: 12 ✭✭
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?

    PS - I don't see a way to set up this post to have email notification that there has been a reply???

    @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.

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