AutoCAD - HOW TO explode then rebuild solid from exploded parts?

[MichaelBrenden]

Make a solid box.

Draw a circle on one surface.

Extrude that circle "thru" the box, from side to side.

SUBTRACT the extruded cylinder from the box solid.

AutoCAD gives a box with a hole "knocked out".

 

Now, EXPLODE that box w/ a hole knocked out.

AutoCAD gives a bunch of regions (representing edges of box) and a cylindrical "surface".

 

How can these surfaces and regions be put back together again into a single solid, equivalent to the original?

 

AutoCAD 2011...yeah! Still awful, so awful, when trying to make it do something obtuse that should be so intuitive.

I guess I had nothing better to do so I took up your little challenge and was able to recreate the box with the hole in it without a problem.

 

After exploding the box I erased everything I did not need and used the PressPull command on the remaining region.

 

What's so difficult about that?

Here is an example of what I was talking about.

Re: previous image.

 

Lower left. Solid box with circle ready to be extruded.

 

Next. Solid box with extruded circle subtracted.

 

Next. Exploded box. I erase everything that is black in color and use PressPull to extrude the remainder.

 

Upper right. End result is solid box with hole.
