Loft problem.

Interesting ! Did you select the faces from the model or the menu ?
I have now found that when I select from the menu it works perfectly without any other selections or deletions etc., but when I select from the model it fails. You can see why by looking at the the differences. ie. the good one just has the faces selected.
What puzzle me is that I have watched many of the training videos and found no reference to this. In fact they all seem to select on the model

I simply select from the model by clicking on the gray area or selecting the lines I want. Are you window-selecting? If so that usually doesn't work well with lofts, and also picks up vertices that are only confusing to the loft tool.

You have hit the nail on the head ! I was window selecting. Selecting as you suggest worked fine even with the aerofoil sections. |ust trying it out - I seem to have the loft showing in the isometic view but not in the menu. Normally when I delete the loft it is removed from the model as you would expect.

Sorry the last post was dumb ! I was not looking at a loft - it was the front sketch which made it look like one.
