Efficient way to "close" a loft?

Charles Has No Last Name Feb 16, 2013 5:00 PM

Hello all,

I am trying to model a wing-like shape by creating a loft from cross-sectional sketches. The end of the wing needs to be rounded but due to the way I've done the loft, I am forced to "close" the wing by adding a secondary loft. I am redrawing the last cross sectional sketch, splitting it into two, and creating a loft out of these two sketches (guided along the profile of the tip).

Is there a way to include the wing tip from within the first loft? The reason I ask is because with the current approach you can see a difference between the first and second lofts, which will cause a problem when I attempt run a CFD analysis.

I have attached a pdf with images prior to the addition of the second loft, and after adding it.

Thank you!

Charles,

It is hard to give you the definite answer in this situation because I don't really know the specifications for the end wings. If you just want a round end, there are several ways to do it, and each would give you different shape. Thus change the result of your analysis.

I attached one way to closed a loft. Keep in mind that there are other methods that may give you your desired shape.

Also, using two sepereate loft or two seperate features to create the wing is not necessary the wrong choice.

  Thank you!
  
  I noticed my mistake: Neglecting to include a point (created as a separate sketch at the tip of the wing) in the loft options.
  I thought you could only include closed sketches, not just points.
