How to delete faces from solids and meshes

[Reid]

Are faces erasable from solids and meshes. I can imprint a face and then delete the imprint? is it all Remove Face does? I want to remove a face to see the insides of my box, without making it see-through. I can not do it to a mesh either. Or, is there a way to arrive at opening a 3d object by deleting a face? Meshes can be turned to surfaces. Perhaps,I can have open ended surfaces?

Why not slice off the face of your box using a surface? Can be done in 2010.

[Reid]

I tried Surface but all it does is slicing, then it generates a face along the cut closing the object instead of creating an open ended 3d figure as i hoped. i think 3D objects in ACAD are defined by closed geometry and that's it.

And I think you are incorrect.

 

The surface is created solely for slicing the object (box) then it is discarded. Carefully read the option AutoCAD gives you regarding the solid to retain. The default is Both. Accepting the default requires the user to erase what they do not want.

Here's proof. Pale green box is before using Slice command; red box is after. The surface I used to slice the box front was erased after use. It (the surface) was just a simple extruded line.

Look at post #30. An arc that was turned into a surface via the extrude command was used to lop off the top of an object.

Did you leave out something ReMark? It looks as if your red boxed has been shelled?

 

I believe that is what the OP was referring when he tried to slice the solid and it only resulted in an additional surface.

 

I think "Shell" is needed for a solid box...

I assumed, perhaps incorrectly, that since the OP said "box" as opposed to cube he had already discovered the joy of "Shell".

[ReMark]

From left to right.

 

My "shelled" box. No interior visible.

 

Box with simple line.

 

Box with line extruded to form a surface.

 

Slice command used with the "Surface" option. Retained back of box by letting AutoCAD remove the front for me.

 

End result (in red).

 

Questions?

It looks like shell to me on that image, but Remark would mention it if it was the case. I tried Surface, but all it renders is an additional face where the plane sat. No luck with open-end geometry.

[Reid]

yes i know shell. it obviously creates closed geometry by default.

Then I obviously don't know what it is you're looking to do for which I apologize for wasting your time.

 

Yes, as mentioned, I did "shell" my box to create a true box (or container) prior to carrying out any other commands.

is it all Remove Face does?

AutoCAD solidedit delete face deletes the face and heals adjoining faces/

Autodesk Inventor gives you the option of Delete Face or Delete Face with Heal. The Delete Face without heal results in a surface body (not a solid body).

 

I want to remove a face to see the insides of my box...

 

Maybe more of an explanation is needed. I've read this several times and still have no clue what you are after. Exactly what is in your "box" that you want to see? Do you in fact have a box (internal volume) or do you have a solid block of material?

 

Perhaps if you could zip and attach your file here.....

I wouldn't mind seeing this mystery "box" as well.

[Reid]

By deleting a face I mean to get rid of it entirely just like you would tear away the cover of your shoe box. All you have left is a card box without the top. I wanted to place the details of the foundation of a pier inside that shoe box, working in 3d. I drew a box and then wanted to removed the top face thinking that this way I will have access to the bottom of the box. There are ways to do it otherwise with shelled objects and subtract geometry so there is nothing here tat can not be done.

[ReMark]

Just construct a box with no top then and be done with it.
