Regarding Patch Operation

[IEngr]

hi,

As you see in the above image, the fillet area is created by through curve mesh feature. The surface is tangent to the above and bottom surface. Now when i patch this surface with the solid, the above error comes. I am not able to analyse why this error came, since it is closed loop. Kindly help.

Does the blend run around a closed loop? It appears not to in the pic; if this is the case, do the "end cap" edges of the blend meet up with the side faces?

Have you tried reversing the direction of the target region and/or the tool direction?

The error message normally means that the edges of your tool sheet body are longer away from the target than the "patch tolerance". (expand the settings in that dialog, try make the patch tolerance larger.)
When you run the patch feature, all outer edges of the tool sheet must lie on the target body, it must be water tight.

The patch feature has a patching tolerance, increasing this will make the feature do the job, but if you need a large tolerance , there will be an gap the size of the tolerance in the resulting model where the tolerance applies. In NX perspective, the edges does meet, within the tolerance.

If this does the trick, you can try go back to the curve mesh and tighten that tolerance and then keep the patch tolerance.

In other words, the surface(s) MUST ENCLOSE A VOLUME or fully intersect with the solid body. Using Patch for blending will be hit and miss - it might be easier to perform this with surfacing rather than hybrid modeling.
