sketching a section from tabulated data

[nilmani]

hi, may be this has already been discussed in this fourm but i couldn't
find it and hence would appreciate your help. i have a set of 2D
points (x,y) pairs, that define a complex profile (for example, a
section of an airfoil). the data is in an excel worksheet in two
columns. how do i get this data in to WF2.0 to create a sketch that i
would subsequently use for extrusion? thanks, nilmani

I don't know if you can read your data into Sketcher, or that you'd want to.

You can read in the coords from text files to create points or datum curves. It's been a while and I don't remember the particulars, but a global search of Help for ".ibl" and / or ".pts" should give you everything you need (there are example files, IIRC, to show you the formatting).

nilmani,


I don't think you can read a data from excel to the skecher, the only thing you can do is create the curve data points in excel and convert it to .ibl file. Follow the formatfrom sample attachedto create the .ibl file then use the .ibl file to create a curve from file to be use for protrusion,revolve,etc., by the way just saveas the excel file to .txt then rename from explorer the .txt to .ibl extension. Hopethis helps. By the way the sample data are x,y,z value of an airfoil.

Thanks, jeff4126 and jayuy. I hv successfully created datum curves using text data in IBL file. It woked fine. -nilmani

You might want to use variable sweep rather than extrude to create an airfoil. Most modern wings have several sections with different profiles. Say root, midsection and tip. So you define the curves for the root and tip of each section and sweep between extremities. Then you can either join or assemble the resulting surfaces.

Pommares, <br style="font-weight: normal;">
You are absolutely right. In fact, I
did generate an airfoil with four varying sections: root, two
mid-sections and tip. However, in order to do that first I needed a
mechanism (IBL file) to create the datum curves from tabulated data.
Thanks,
