Smoothing Question - Presenting Walls more Elegantly

Using Trevor Taylor's great source code (http://sky.fit.qut.edu.au/~taylort2/MSRS/) I created a world that imports a 2D bmp map drew using "MS Paint", see:

The bmp file:

The world as it is shown in MSRS:

A zoomed view:

My question is as follows: is there any elegant way to build the rounded walls so that they don't appear like big stairs?

Maybe somehow to create an arc entity out of a group of wall neighbors? If so, how could it be done?

Any other suggestions, please?

Thanks,

Uri.
