Replicating Organic Lofted Dining Table

maxmclaughlin

I'm pretty new to OnShape and have been having trouble trying to replicate the design of this dining table I found the other day.

I think my approach is all wrong - what I've ended up with is a series of surface fills driven by profiles and guides. The whole timeline feels like a complete mess, the surface curvatures don't match up and my surfaces break whenever a dimension is changed. Maybe this isn't the right place to ask for help with this, but if anyone could give some loose guidance on how they'd approach modeling this it'd be greatly appreciated.

Here's my part studio for reference.

Per @matthew_stacy, this would look better with lofts, but using fills seemed quicker. Not exactly class A surfacing, but I think it turned out reasonably well.

@maxmclaughlin loft features, with guide curves, might give you more bang for your buck.  It is sometimes challenging to achieve higher order continuity between adjacent FILL surfaces. 

For example, if you turn on CURVATURE VISUALIZATION (in the view menu ), the zebra stripes indicate a surface discontinuity where Fill 12 meets Fill 14.  That might be easier to correct with a loft feature.

Save the FILL tool to close whatever gaps you're left with at the end.

@maxmclaughlin, I don't think you're too far off. It does seem to be a lot of features in your tree, but your general methodology looks valid. If I were doing this I would start out similarly, splitting the surface patches between high points. This would yield the same primary 4 Fills that you start with. But all those extra fills around the border aren't really necessary since those surfaces are simple prismatic surfaces normal to the table top. You can just create a simple rectangular solid and then perform a Replace Face to change one of the flat sides to your fancy surface. I may tackle this model and come back with an example.

@mahir that's beautiful.  It looks ready for some fine grit sand paper and the first coat of linseed oil.

Sorry I missed this earlier! That looks fantastic I appreciate the help with this

No problem. Happy to help. Thanks @matthew_stacy
