uniting two solids? or maybe another way

[john.w.dailey]

I am new at Pro/e so I hope I am not making a fool of myself...

I am trying to create a collection of hollow boxes (connected by walls that they share) almost like the film walls in a foam...

I have tried to do this several ways and I keep running into problems. Currently I have drawn all the walls as a sketch, extruded them as a surface, and thickened the extrusion... This gives me all the walls except for the top and bottom quite nicely... But I can't seem to figure out how to put the top and bottom walls on.

I tried using boundary blend to create all the walls. I get surfaces that look good, but I can't figure out how to thicken them. I tried thicken, and all I get is errors (could not intersect part with feature). That would be a lot of work to thicken each blend too...

Is there some way to make a surface that is the outer perimeter of my whole part and extrude or thicken that, and have the part be the union of this thickened surface and the interior walls of my "foam"

Here is a screenshot so you can get a better idea of what I am trying to do...

There is an option for closing the extruded surface called cap ends. That should do your trick. What are you making?

It appears to be a planer feature, can't you just use all the outside edges in your part for your sketch and extrude it the thickness you want?
