Area of Projected sketch - Unable to determine

Hello, I am unable to find the area of this projected Body. I tried to find the connect all the missing dots but it is still not giving me the area. Am I missing something? Thank you for your help.

I am unable to find the area of this projected Body. 

Not surprising.

Divide and Conquer, draw a temporary line across an area like this bottom right corner.  There is a hole in the middle triangle.

 

Good luck....

I see lots of duplicate geometry in this sketch (splines on top of splines, etc), and a few disconnected endpoints.

 

By eliminating these in the lower portion of the sketch, and by combining some white dots (no coincident constraint), I was able to get the profile to be partially recognized:

but, I didn't have the time or patience to fix the entire sketch.

 

I wonder if projecting the whole body is really what you want.  This will easily create a lot of "extra" curves from parts of the body which have the same silhouette curve.  If I do a projection of the intersection with the body, I get a much better result.  Still some issues to be cleaned up, but I was able to make it work:

model is attached (including my half-fixed original sketch)

Contentious issue is why doesn’t Fusion get it right first up,

should not need to teach anyone, Divide and Conquer!

Must have been one of my first forum questions - Project > Intersect a body and no profile.

(checked - June 2017)

 

Might help….

well, this is a VERY hard geometry problem to solve.  Silhouette edge projection of a complex body can result in a LOT of curves being projected.  That said, we are working on this.  I expect improvement, but never 100% success.
