Hello,

I'm a student in eng. technician school, have learnt about SW in few classes, but now I've reached my limits.

I wanted to make a drawing of frame of a sport-wheelchair, but its curves and several planes gave me a headache.

See attached what is the result..

I am not satisfied with it, and I think that there should be an easier way to create the same frame, but found no solution yet.

I hope you can give me some idea, advice to find this way.

Thank you in advance.
