polynurbs issues with close fit

Altair Forum User

Hi there,

I have been working on optimising a bracket design and inspire has produced a suitable optimised model. I would like to refine the surface finish of this model using the polyNURBS feature. The issue is that the model includes a feature which resembles an I-beam, but PolyNURBS turns this into a cylindrical shape. Is there any way to closely follow the contours of a shape more closely with the PolyNURBS tool? Please see the attached images for clarification.

Thanks in Advance!

Nigel

Hi All,

I would really appreciate any help with this issue if possible. Is it actually possible to closely follow the contours of the shape?

Many Thanks,

Nigel

Hi Nigel,
from my point of view it is not possible within Inspire to do this automatically.
You should do it manually by splitting the polynurb in 2 or 3 and move the vertices.
