Hello everyone and seasons greetings. I searched for this topic on the internet and wound up here.
I followed Jose's advice using edgesurf to create a propeller. You can see it here:

I am using Acad 2007.
I used thin elliptical sections that were spaced upwards on the z-axis and individually rotated. I connected the edges with a 3dpoly and then egdesurfed the section between ellipses.
I used a cylinder solid as the hub. At this point I would like to trim the connection between the prop root and the cylinder but the union command will not work. Any suggestions?
I am also trying to do a model of a complicated chair.

I created this by first making a polyline of the edge of the chair ( if you are sitting, the edge coresponding to your left side) and then extruding it. I then fiilleted (a fishy term) the edges. Now the problem is how to make the back of the seat narrower than the front. Here is a picture of the chair for more clarity:

Any suggestions? It's amazing how even a simple chair can be complicated to model correclty in 3D.
And finally, thanks for your patience, can you recommend a good book to help modelling these types of surfaces.
Cheers,
Jacques
