Right, I'll try that. Thanks. Um... I would like to know how to export - and yes, I've found the "Export" button, under File, but when I tried to use it I wasn't sure (and obviously got it wrong 'cos it didn't save anything) exactly HOW to export. I have hunted through the manual - all three sections - and although "Import" is mentioned, I can't find "Export" (even if I could understand it). I want to export as... "TowerA.dxf" - since I can't find any .obj options to export under. (Which is what I really wanted, but dxf will do.) I mean, WHERE do I type the name I want to export it under? And then what do I press? Please help? (and you didn't explain wht you mean't by "smoothed with simple subdivide on" - do you think you could explain that? I.e. tell me how to do it? Please?
