Modeling a Heart

giacomo_ardesi

Hi all,
Learning Onshape (and loving it)...I'm designing a ring to 3D print for my daughter Anita's 12th birthday...I'm getting there but I'm having trouble modeling a little heart where you can see the sketches...https://cad.onshape.com/documents/7aa57cf32b85467194417695/w/139f014241e241119e21b702/e/65fbd6cfa960421184c4839d
I tried loft from one point (sketch 7) through 6 and other point (sketch 8), using 9 as guides...but no luck. I guess a tool such as revolve along guides could do the trick...Ideas anyone?

Thanks
Giacomo

That's a tricky shape to produce at present in Onshape. 
Here's one approach which works: lofting between three profiles as shown, and then mirroring about the midplane (AT Plane 7 in the modified model)

I had to edit a couple of your earlier sketches to get it to work, notably your sketch 9 (shortening it to make it suitable for a guide curve)

There's one more "mirror" feature needed to produce the shape you want, about the Top plane

Thanks but it doesen't open a model...
