Everytime we try to create the Wing in CREO 2.0 using the instructions given in MathCAD.
This was there error we kept on getting.
Has anyone else experienced this problem and how did they fix it?
The Picture did not show, so here it is.
It appears that you are trying to generate a wing by importing airfoil coordinates. The erros you are seeing usually occurs when the file you are importing is not formatted correctly. You can try to fix the file format. Alternatively you can design the wing using coordinate points directly within CREO.
I was able to make the curve, but I could not find a way, or a tutorial that taught me, how to connect the final two points
There are no tutorials that will teach you that and several other similar things. You will have to figure it out yourself. The key is to practice. The more you practice, the easier these things will get. You can always connect two points by a straight line or a spline.
