3d Surfacing with cross sections and plane view

Hi,

 I am currently working on creating a 3d surface for a wakeboard. I have 2d cross sections and plan view to work with. I have tried to create a loft using the cross sections as the guid rails. ( I tried lofting the cross sections already and that did not work) The problem im having is connecting the plan view sketch with the cross sections as they do not always intersect with the plane the plan view is drawn on. Is there a way to project that sketch until it intersects with the points of the cross sections? I have tried everything I could think of and am still stuck. Any help is much appreciated. Attached is the file with the 2d sketches laid out.

Did you import these sketches from some other source?

 

It looks to me like you have far more nodes in the splines than necessary (and even lines as splines?).

 

You can Project Geometry to use Coincident Constraints to tie profiles to guide Rails, but I recommend simplifying the profiles first. (I'm not saying - change the geometry, but use primitives like lines and arcs where appropriate in place of splines, and the best spline has only 2 nodes - so reduce nodes.)

 

Profile Sketch5 has a gap - not a closed profile.

I imported the sketches from a client and agree there are too many nodes. After i simplfy the model, how do you project geometry to include coincident constraints?

Use the Project Geometry tool.

 

I recommend that you go through these and then come back to this project.
