Solids modelling problem: 'Reverse Mirror?'

[APE Design Ctr]

Hi All,

I have an imported CAD file from AutoCad that is in the shape of a 'Bent Chocolatebar' (cant think of a better way to describe it) where the squares of the bar would be on the outside radius. What I need is to mirror this file so the squares would be on the inside radius, leaving the outside to be smooth.

Is this possible, or do I need to re-draw it? The 3D mirror gives me only flipped geometry.

Here's a link to the image:

Thanks!

It seems possible if you want to go through the hassle of reversing the geometry of the Z coordinates of the indents-outdents.

or

You could harvest out the protrusions and attach them to the concave side of a new blank 'Chocolatebar'.

Have fun with this one... let us know how it goes ; )

Eddie, why do you get to have all the fun ?

Seriously, it's such an intriguing problem and deserves a simple solution.

It appears that there are repeated shapes populating a 90? arch convex surface. If this is the case then the arch can be divided into complimentary arc segments each containing a rotated or reflected shape. The grid can either be a 90? ( or subset ) or a 60? ( or subset ).

Ideally, creating one or more fractal arc segments with shaped concave surfaces would allow both rotated & reflected recompiling of an upside down 90? arch.
