Fix it? No... you should just scrap it.

Hi Kurt my posts intention was to clarify the nurbs/solid confusion and not to correct your model...Also note I am not implying that is necessary on your model.

IF you want to go to production with it, there are few thinks you need to take into consideration.

So Lets say that is an injection molding part using high gloss plastic...The outcome will not be smooth. Seams will be visible were you have applied fillets. AND that is the reason why SolidWorks been trying hard to improve their surfacing tools...So the REMEDY will be Surface Modeling were you have more control...G3, G4 etc. THAT's how apple does it among others.

I could write an essay But most of the info is in the Solidworks manual.

things to look for:
-Explanation of C0 through C3
-curvature vs. tangent connection of surfaces
-curve continuous surface connections for a seamless look
-maintain tangency
-
-

Hi Yanada,

Thanks for the explanation, not sure if I agree with your point that surfaces don't come out smooth after molding
Tomorrow I'll show an example of a project I have been working on the past few months with some nice smooth seams in those difficult areas.

anyway, here is a small update on WALL-E

[rusteberg]

pretty gosh darn smooth if you ask me..... i'm jealous i don't know solid works or have access to also jealous i don't have your master patience Obi Wan Nurbinomi.

[yanada]

As I said

Also note I am not implying that is necessary on your model.

C3 etc. is not necessary on simple mechanical parts like this one...
Nice model anyway

[Bubbaloo]

Now he's calling your model "simple"...

[NicoR44]

hehehe, don't worry Yanada I know what you mean you're talking about the more complex (organic) shapes, but still I'm not sure I agree because, I know a few people over at Phillips here in the Netherlands and I know that they use SolidWorks for about 90% of their consumer products (of which a lot are class A modelled body's)
and thanks for the compliment

And thanks Tom

Have to agree with Yanada, using simple fillets does create unwanted lines, especially wit non organic high gloss shapes. Look at the sample (using the fabulous auxpecker) where the start and end of the fillets on the left are clearly visible. On the right conic surfaces are used and there it is impossible to pin down the start and end of the rounded edge. Knowing some Philips products shows that they simply don't always care about that but as a product designer myself i'm very keen on avoiding these lines.

woow, not sure what's going on here, that's not my experience, see:

[djflod]

that is going to beeeee so Curt-ig

great project Curt

[EADC]

Well, obvious to me
It's not always a problem, but if you put glossy paint on visible surfaces these lines really show.

Here's a nice SW modelling challenge for you Curt. Just try to get something similar (but smooth). Drove my SW trainer nuts.

[NicoR44]

Thanks djflod

Hey EADC, arrgghhh, that's a good one I will sit on this one

[yanada]

woow, not sure what's going on here, that's not my experience, see:

EADC has the answer, also Curvature Analysis tools inside SolidWorks will show more problems.
Curvature continuity and tangency on surfaces can be checked by using Zebra Stripes Visual Display available inside SolidWorks. (is agood place to start before you get to more advanced Analysis tools)

[EADC]

FYI Curt, removed some boundary curves in the fillets prior to posting to make the solution less obvious.
