Points Drive Airfoil Profile?

[REDesigner09]

Hi Everyone,

If I have a table full of points, is there a way to insert this in to NX Excel & have it create the airfoil profile? If so how?

Thanks

If the points are organized so that they represent the wings cross sections/profiles, you can create splines from a text file. For information about the formatting of the data, open the User Documentation/Help Files and search on the string "Inputting Points from a File". There you will find several approaches for creating curves and/or surface from text files of data points.

To an Engineer, the glass is twice as big as it needs to be.

HI John,

I found the info., but it's still not clear to me on how to set one one up.

I have point clouds at specified radial heights or I have an Excel table with X & Y positions.

Are there any examples to seeh how this works?

Thanks again...

What version of NX are you using?

Attached is a simple example file. Open a new Imperial units (Inch) part file and go to...

Insert -> Curve -> Spline...

...and select the 'Through Points' option. Then push the 'Points from File' button and select the attached file. This creates a curve which represents the bowl of a wine glass.

Hi John,

Thanks for the example.

I did create something from the DAT file & I guess it's in a bowl shape. However, it appears to more a a single line entity or spline or nothing like a wine glass.

Is this what it is suppose to be?

As for the table - How to put headers in the columns, without having file read them? Can this be table also be inserted into NX Excel to generate profiles?

Thanks again.

Yes, if you sweep the curve about the Z-axis.

If your points represent airfoil sections, then you will need to create a .dat file for each section and use the technique I described above to convert the points into curves which can then be used to create the airfoil shape as a surface/solid model.
