Tim did a really helpful PDF with regard surfacing about 18 months ago

I learned heaps from it - even after using the tools for 8 years

: |

I can't seem to track it down now .. perhaps someone else has a copy ?

I'm sure we can find it between us !

Yep "U's and V's are in the same or opposite directions"

It's been explained to me - but I still dont get it

I think it's a quote from the Dalai Lama

LOL!!

UVW is the same as XYZ (apparently). It confuses the hell out of me too! Engineering based designers tend to think in XYZ and 3D modellers in UVW. I think in Shark's desperation to find a common ground (about 50/50 'engineer desigers' to 'modellers', sound about right?), both units seem to look if they have been adopted :eek: (I'm probably talking a lot of nonsense again here!! ;) )

Personally I much prefer X,Y and Z. X being side to side, Y up and down and Z , front to back (depth), but until that axis in VC is updated (fattened up and increase in font size), I'm not too sure which way up or down I go half the time! :p :D

Steve, this forum isn't that old you know (2007?). If you want to do some surface modelling, and then get back to the forum, with your results, I'm sure you could start thread aplenty. :D

Most of us have been stuck deep in beta testing, so there isn't always enough time for other discussions. But please play away, and if you find any odd behaviour, please get back asap! :)

16 months? I said it was young :)

I'm sure Tim is aware of your concerns as we speak, but perhaps you could post your findings in the beta thread too?

regards,

Tom

Steve,

The way I see it is that Concepts Unlimited only recently got taken over by Punch! software (last year?). FWIW, I don't envy Tim at all, steering this huge beauty of a beast (the software), but he's doing a grand job, so give him credit. Like such competitors as Solidworks, Shark FX is a powerful ACIS-based CAD suite, but it doesn't have the same cutthroat stealth marketing as Solidworks does.

If there is an error, then there could be a problem with the basic algorithm used to produce this sketch that will need looking at. I'm absolutely positive that Tim will get round to addressing this asap, but like I said, this is a small company, and some things that needed addressing a few years back are only getting sorted out now.

Alrighty? :D

And yes, try the beta forum, because I would imagine that if this is a fault, that it will be something that could also be addressed in the beta.

good luck!

Tom

Pretty sure that UVW coordinates are specifically used to map 2D textures to 3D surfaces, or to directly create 3d texture on a surface, the surfaces created in XYZ coordinates (though some applications may use UVW coordinates for surface creation). Both UVW and XYZ are orthogonal coordinate systems, so the designations are really just to differentiate purpose, and have achieved convention for that purpose.

Jol,

I hardly use surfaces at all, but I'm speculating that this problem is occurring at a surface discontinuity (radical change in surface), or perhaps at an intersection of two or more surfaces.

Is this the case?

From the original model posted, the only problem was the fact that the end points on the intersecting curves where not actually connecting (0.001/0.002 out of position), once those where aligned then I did not receive the UV error.
