Weird problem with negative |
|
|
Hello again:
I have given up on trying to extract my airfoil data points using EXCEL, and have started using SCRIPT files, by manually copying them into notepad.
Everything works except a for a weird problem.
If you look at an aircraft wing from the front, you have a left and right wing. Let's call the wing on the left positive and the right side negative of the fuselage center.
Whenever I plot the airfoils using the SPLINE command for the right side, I get great results.
When I plot the right or negative side, it goes to pot.
I have attached the script file.
Please note that the attached file is actually two files.
Other than the NEGATIVE "Z" axis, everything else remains the same.
What am I doing wrong?
Thanks for your time in advance
Tony

SPLINES are directional, try MIRROR command perhaps for the second one?

Does SPLINEDIT's rEverse option help?

Hi;
As stated when i tried to enter the negative side of my airfoil, everything went to pot.
THIS WAS THE FRONT VIEW
Frustrated, it dawned on me that I could swap views and instead of entering a negative "Z" axis,
I only had to reverse VIEW to BACK.
Now I just enter my "X" axis number as negative values, but leave my "Z" axis values as positive and it works. |
