Modeling using Points- update

Hello All


I need to create a aerofoil profile using the set of points given.
(Say 89 points for one cross section, and it has 5 sections for aero geometry).


The tag is these points might get changed in future. So need to create the profile in such a way, in case of future update / Deletion of any existing point / addition of more points, the modeled profile should get updated accordingly.


I have dat files for all five sections (5 files), which is the input file for geometry.


Can any one suggest me a best possible solution ?

Hi ,

you can consider Knowledge Fusion as one of your option.



Re: Modeling using Points- update

You can create a series of 'Point Set' group from the data files and then create a Spline by selecting one of these point set groups.  Later if the data changes you can create a new 'Point Set' group and then edit the existing curve by replacing the original point set with the new one and everything will update as expected.

Any chance of elaborating, John? Which spline creation method?
