Problem with Trim

[cgg]

hi Dr Ben

i think you should do this with the 'FREEFORM FILLET' ,the other kinds of fillets are for other uses.

What kind of shape are you trying to model?

.. the better approached is called socking but it is more complicated than using trims and fillets..

hi gmask
what is socking ?

I think there is abetter "socking" tutorial than mine but it is essential the same thing..

I'm not sure why it is called socking.. I think because the typical example is connecting a ball to a cylinder and it resembles a ball and socket or maybe because it looks vaguely like a sock?

d*mn that looks way too complicated for me... but ill give it a try
thanks for the tut gmask :buttrock:

It depends on what you need it for.. if you are planning on deforming a surface witha trim the results can be a disaster. If you are modelling solid objects then trims are fine and save alot of time.

If you rae modelling a complx character do not be tempted to use trimes for eye holes.. but it the character is simple it can be gotten away with allthough I am not reccomeding it.

Also most problem with trims can be solved by increasing the divisionsof the surface or even moving the project curve slightly can solve various problems.. I hate trims for the most part..and would rather sock.

One of the animation problems you might run into with gmask's tut would be the difference in isoparm locations. The rez is different on the joined surfaces. I think this would cause problems during deformations. Of course it looks fine on a car or something like that. Nice one-pager tut gmask:thumbsup:, btw.

That is true but you'll notice that the isoparms are equally placed so it would be easy to increase them to match. In this case I was not thinking about a character and I still have no idea what the OP was trying to model. You could also use tessleation values to get the correct division but I would reccomend hardwiring it with isoparms.

Hmm.. now that I'm looking at it again I left one side of it uneven. oops...

ps: Whats the differecne between the 'thick' and the 'thin' iso's ?
are the fat ones something like starting or base iso's ?

The thick lines on the border of a trim are called trim edges and can be selected by right-clicking the selected trim surface and choosing "trim edges" and then clicking the trimmed edge. You can also use Edit Curves->Duplicate Surface Curves on the trim edge to make a new NURBS curve which can provide you with additional options.

hey thx for those great and fast responses ..... well i will try the complicated method someday later ... for now i have to get my thing done

the thing with selecting the "trim edges" worked ! thx !

i could swear i have tried that before ... but well ....somheow i must have messed up :hmm:


well i just tried it ... and there's another little problem ... there are little black spaces at the boarder of the fillet.

i tried to up the tesselation of both the fillet and the trimmed surface .... no changes so far :annoyed:

any idea how i can get the surface to fit better !?

BIG thx ! so far !:thumbsup:
