Combining this two NURB surfaces ?

[Rayx1]

So as ignuf said I have to make surface patches to create the face of the board, I have now the curves in position, I rebuilded them so everyone of them have the same number of spans but when I do SURFACE>SQUARE I don't see any result, of course when I do this I make sure the control points of each curve is aligned with the points of the others, what I'm doing wrong : / ?

[Rayx1]

Finally did it !! I just had to DELETE HISTORY on the curves and then do a SURFACE>SQUARE but you see I hate this couse after a solution always comes another question, I was trying to do a LOFT between my new surface and a curve but as you can see when I choose the ISOPALM on my surface I got like 4 different isopalms that surround the board on the edges which makes imposible to create the LOFT.

nurbs curves and nurbs surfaces are very similar in the way you can manipulate them, you can choose where a curve or surface is to be split into two, on a nurbs curve you can right click over it and select "curve point" the curve turns blue and you can select a point anywhere along the curve, then in the "edit curves" menu choose detach curves. from there you can rebuild as needed.
with nurbs surfaces you select an isoparm and choose detach surfaces from the "edit nurbs" menu.

glad you managed to get the top surface sorted.
to be honest with this particular shape it would be a lot easier creating it using just polys/subD, unless you are doing this purely as an exercise to learn more about nurbs for future use. subD's are great for creating both hard surfaces and organic flowing shapes and don't have problems with the 4 side issues with nurbs .

[ignuf]

with the nurbs surf you have so far you could just convert it to ploys and extrude down

when converting to polys, there are quite a few options in the convert to polys dialog box so it s worth checking out each one to see which option has a better result.

here's a subD model, very simple and quick

[Rayx1]

Thanks, yes, it's mostly done as a practice exercise but I didn't stop in any time on thinking about poly or subD to do the job, mainly couse I really wanted to get it done with NURBS, yes it's way easier with polys but NURBS give you the chance to achieve a really smooth result or at least I don't know the way to do that properly with polys as you can see here in the pic a board done from NURBS and another one done purely on POLYS with extrusions.



For example (this may be another different question, but has relation with this) I had this mesh where I was modelling a jacket for a character (the one that's going to use the board) as you can see on the pic working with low res mesh achieved some nice sharp contour shape on the hand...

...but as they always taught me I gotta smooth couse some other parts of the mesh needed smooth, then I lost sharp edges, this happened to me up there working on the board (poly board). Which you think would be the way to preserve a sharp edge on a mesh before smoothing? (working with polys now)

[Rayx1]

I get this problem when I want to achieve a smooth shape with some sharpened areas, I mean, I can manage to create a smooth or a sharp object but when I want a smooth object with some sharp areas I get lost in the process, the word I'm looking for is "mix", how can I mix sharp and smooth surfaces on a same mesh having that smooth arm but with those sharp fingers from the upper picture?

You've got the jacket here http://www.mediafire.com/?7r6mxp5evrh7p5z

By the way you can see more of what I'm doing right now here http://www.digitaltutors.com/forum/s...167#post104167

I'm looking on digital tutors http://www.digitaltutors.com/11/training.php?vid=3736

[Rayx1]

Well, I know the solution is to use more edge loops on those areas but I was thinking about a sharpening tool or something like crease tool.

[Rayx1]

I'm working on this last issue so it can be answered just with a yes/no, I'll upload some pics.

[ignuf]

if your working with subD's you can crease edges and leave other edges without creases. or like you mentioned you can add another edge line to sharpen the resulting mesh.
if you take a look at the last pic I uploaded you can see the poly box I used to make the sub-D shape along the sides of the poly box you can see the extra edges I inserted top and bottom which make the subD shape sharper at the edges

[ignuf]

I should poit out that there's different ways of doing subD's one way is to use the 3 key on the keyboard which applies a subD/smoothing effect to the geometry , also in the polygon menu you can select a poly mesh and then choose "proxy/subdiv proxy" this makes the poly you selected semi transparent and creates a resulting sub d mesh inside , which is controlled by the shape of the poly mesh .

[Rayx1]

Well, it was a matter of loops, so simple as that but what I always hate of this process of reshaping is that I always add more loops which is not always a good way to go so I picked up the loops I already had and worked with them moving them to give the fingers the shape I was looking for, anyways the board question is been answered, thanks ignuf for helping out, If someone wants to give his opinion about this last pics you can do it here or at the link, thanks. http://www.digitaltutors.com/forum/s...167#post104167

Thanks for the tips, didn't remember about that one.
