I'm having trouble getting OS to recognize the middle profile of my loft and it doesn't like guide curves. The two end profiles are splines and the middle profile consist of two curves tangent to each other. Any help appreciated.

don_howe, 1).I noticed that there is no intersection points between the curve in the sketch 4 and the the curve in the sketch 1(or sketch 9),that is why you can not choose sketch 4 as guide lines.
2).about the middle profile,it is consist of two tangent curves, you can choose them together from the feature list.5

Cant help much, as I have not used that tool enogh to understand it completely.
But I see something strange Sketch 9 and Sketch 1 are the same, why dont you use only one?
Any way, I made a couple of hulls that may help you. I changed one of the Sketches that was circles for a spline line.

I see what was the problem, You need to pierce the points of the profile withe the guide lines. If you do not do that it does not work...
Any way in order to work well there is too manny Sketches try to reduce it to a vertical one, an horizontal and the ribs, you should not need more, and will be easyer to work.1 -

Thanks shanshan, I must have thought OS automatically snap to that point. I will have to watch this in the future. I was able to make the intersection this morning and it works great now.
gonzola_chomon, I got rid of the extra sketches. Thanks for pointing that out to me.

How do you make those videos @shanshan ?0

gonzalo_chomon,I am using a vedio-maker software called "licecap",the format of the video which it records is GIF,so it can be upload here, you can download it from internet,and have a try!2
