Fantastic tool sir!
I've just started using it. Its working amazingly well but when i open(double click) the control point group to alter control point locations for deformation, the object i'm working on vanishes leaving only the control points behind. The transformation done is taking place but I only see it on the object after i click close group. Can you help me figure what i'm doing wrong? I've attached the screenshots for reference.
While we're at it, can you name this plugin you mentioned in the last para? The one that "cuts" a shape following the patterns it recognizes in the bitmap?
Thank you gentlemen! I guess that answers my queries. As i said in my first post i m pretty much a newbee when it comes to extrude tools or for that matter sketchup in general. I hadn't known that the shape of the flat face had any bearing on the profile in the rails(Thought it was just supposed to be that i.e., a flat face nothing more) or that if we divide the number of segments of the curve edge then it affects the number of ribs as well. Thanks a lot. 
Incidentally, the 'four pointed star' thing wasn't my production. I was merely quoting what line of terms TIG had used previously referring to example 'A'. Note that y'all, if you will. As you deftly pointed out Aceshigh, the rectangle term is 'indo'-european AND assuming I am an Indian, i'm the last person to harbour any doubts about what a rectangle(a polygon enclosed by four sides at right angles to each other) or a star(a polygon with sides cutting each other so as to form a star shaped figure)mean. 
I've used the '4-pointed star' shape in this sketchup file sir. This shape, i've scaled and there are adequate gaps but the results are drastically different. The mesh formed isn't at all the same.
Also there is the persisting issue of mesh design. It's still rather plain compared to the elaborate and realistic design formed in your tutorial.
Thanks
Here's my sketchup file in the attachment. As I said, i've used the 'extude edges by Rails by Face' tool here on the shape but the produced mesh doesn't quite resemble the one shown in tutorial. Please review and suggest what has gone wrong. Is it a different version of extrude tools than the one i've been using? P.S. the version i'm working with is v2.7
I'm new to this tool. I was just using the 'Extrude edges by Rails by face' tool when i realised that the ribs produced in my model by selecting the Profiles and rails option were quite different from the one shown in the tutorial. They weren't so smooth or so detailed but rather plain and conflicting. I'm attaching the pictures of the required rib formation titled 'A' versus the ribs produced in my model titled 'B'. I know the two shapes are quite different but that doesn't explain why the rib designs are different.
Can anybody tell me what must've brought about this change? Is there some change in settings that you must do to change the rib type? My extrude tools version is extrude tools V2.7. Any help will be appreciated
