Hi eric,

The model you provided has a radius already applied to it, it's very small in comparison to the model size.
The radius you have on there is about 1 7/8" and the model is 4 feet 11 inches wall section and 42 feet 5 3/8 inches high.

Does the model have to be so big ? or maybe you picked the units 'feet & inches' by mistake and not just 'inches'.

Cheers

All is more easy with "no unities" ;)

Thanks, Danny ...
That does explain it. Dumb mistake!
cheers,
eric
