The technique of entering n/m works only because SketchUp's measurements box accepts fractions, not because it implements a divide operator as such. In a fraction both n and m must be integers. Any other type does not get treated as a numerator or denominator of a fraction.

just clarifying for OP How often does one get a chance ?

I don't think you can do that. You have to hit all of the views on each page and set them all to the desired render mode. It does seem like an interesting feature, though.

Vertex, Vector, yes, those Oh, well that's not great news, I thought I was onto something there. I guess I'll have to revert to my other software. It would be a really good feature to have in future though...

and these option is also very good !!!!!!!!! http://forums.sketchucation.com/viewtopic.php?f=323&t=38637&hilit=hatchfaces Download plug in called Hatchfaces

That does look nice. good work. I can't post the LayOut files I've done because they are all for other clients. You can get some of them here, though. This one would be a good example.

Yes. I need all the points I can get.

why fun ? I need these option a lot, I would pay that!
