3D lines to surface to solid

[DanMac123]

I am trying to create a complicated 3d celtic weave patern and turn it into a ring i.e bend it 360 degrees.

First step is I can't work out how to turn some 3d lines I have created into a surface, then a solid.

after working this out, how do I then emboss a celtic weave straight (think an almost flat plait that has bumps in it) to a surface onto a sphere?  or just bend it 360 degrees?

cheers,

I did not take the time to try to really fix this, but when Sketch1 and 2 are fixed, the file should look something like attached.

You are missing Tangent constraints in Sketch1 and I think a Colinear in Sketch2 (why 2 lines where 1 would do the job?).

Thanks for your reply JD,

I've been using inventor 2014 for 6 months and have just moved to 2015.

I have created a weave pattern that will weave in and out of multiple versions of itself.  Ideally I would like to make my 3d solid wrap around a sphere into a ring shape.  

any Ideas on how to do that?  the last sketch is the spacings required.

I have attached my ipt, I have fixed my constraints or so I believe.  If you drop EOP to the bottom you can see what I have made.  It was quite tedious since I used 3d sketch to create intersection curves and then use 3d lines to create sections in my part to then patch individually and then sculpt into a solid because I couldn't seem to beable to do it in one go.

This took a rather long time.  

Q1. Is there an easier way ?

Q2.  how do I then wrap multiple spaced replicas of this around a sphere to create a ring?

p.s.  the whole point of this project is to 3d print a mold to create an easy path for two strands side by side to fit in the mold.
