Attached a csv file (winzipped as csv not an upload file) created by an online prog for a NACA section.
The red line in the image below is what I need along with the chord line that runs from leading edge (blunt bit) to trailing edge (pointy bit !)
What do I need to alter in the csv file to allow Rhino to generate either the curve or a set of points I could then use Inerpolate Curve on.
could someone attach the csv file (zipit again) rhino needs so i can see the edits made ?
I wonder if it needs column headers or all the text taking out, Also should there be a column for z value, 0 I presume as this is a 2D shape
Importantly what are the exact steps to do to bring it in ?
I dont need the camber line (brown line) if that helps, though to have that created as well would be clever.
green lines not needed. brown kink at front shouldnt be there either !
chord line is the black line 0,0 to 100,0. but should be identifiable from points for red line anyway so not vital.
Not sure if different lines can feature in one csv.
This would be very useful to understand indeed for me.
