Surface Fillet

[Karl@CP PISTONS]

Hi All,

I placed a file in the MC8 folder named surface fillet. I cannot seem to get this to work out properly. The red surface does not appear to be tangent. If the spoke surfaces are mirrored it (the fillet) looks bad. Any one have a few to look at this and show me how to do it right?

Karl, check out 'surface fillet-bt.zip' in the MC8 folder. See if this is better.

 

I rebuilt the bigger spoke surface in Rhino3D because it checked bad. Then I made the new fillet surf in Rhino also. It should be tangent now, take a look

 

The various surfs are on different levels so they can be compared to the orig surfs.

Thanks for the help Bernie.

 

When you say the surface checked bad, What does that mean?

After mirroring the new surface the fillet looks pinched in the center. I'll keep hammering at this.

Any tips would help at this point.

I'll keep learning by doing but the deadline is approching fast

"When you say the surface checked bad, What does that mean?"

 

Analyze-Surfs-Check model - I set to .0005

 

Only tip I have is create more cross sections to force the surf to the shape you want.

 

Which way are you mirroring it so I can duplicate what you see?

Hi Bernie,

I am mirroring the spoke about a line at 126 degrees to create a fully concave spoke section.

Thanks for the analize tip I didn't know about

that

OK - got the mirror. I believe the problem is where the main spoke surfs meet at the mirror line. there is a sharp corner at both points. These will have to be blended better.

 

Give me an hour, I will try something here.

OK Karl - look at surface fillet-bt2.zip.

 

I rounded off the spoke surfs, trimmed back the new fillet surf and made a surf to fill the space.

Karl, I put up a file called surface fillet blend.

I created some cross sections through the spoke and wall surfaces and then create,spline,blend, broke up the long splines on the original fillet at the intersctions, and created a coons surface, 10 x 1. Looks reasonably smooth.

Check surface-fillet-bt3.zip

It's just one fillet surf now.

Hi CamGuy,

The fillet is mathmaticy (sp?) correct but looks pinched in center. I have to work to cosmetics only here (needs to look good ).

Thanks for the help

Karl

edit: many thanks also bernie

but same cosmetics is the only thing important here.
