From Steph
The letters of the floor Church were simple Text curves (format 3dm) from Rhino 3D imported in Moi
Extrude + Chamfer ---> seems that gives problem :)

For the Gun : points are not yet "auto welded", good matching surfaces, all normals are in the same way :)

For the church : here an Avi video with some bugs:) http://stephlx.free.fr/MoI/bugObj.avi 13 meg :)

For the Old Door : after export Obj in C4D no possibility to "auto weld" points of the fence, too numerous points, no enough Ram !!! (2 Gigas:)

Various complaints :)
Infinite grid on the "2D views"
Scale Tool ( I suppose 1/100, 1/1000...or unity cm, m, inch ...) ?
Text cotation (?)
