Creating creating a couch frame inside a solid form.

[rory6D5ZF]

Hi,

I have modeled a quite organic shaped couch/sofa using the form tools.  I would now like to model the internal frame (made from plywood and timber) for manufacturing, as well as the foam layers that sit on top of the frame.

What would be the best way to go about this using the form I have created as the outer shell?  I imagine this would be quite common for lots of product design where the exterior is modeled and the internal components are then added later. So if there any similar video tutorials that someone could point me to that would be great!

Thanks so much,

Rory

Sketch the frame inside the outline, with approximate clearance or depth of tightened foam, on appropriate sketch planes, Plane on Angle, or Plane on Path becomes handy.

Can demo with your data if stuck.

Might help....

HI rory6D5ZF,

as @davebYYPCU  said, build the frame with appropriate clearances/depth of tightened foam.  More specifically, think about the thickness of the fabric, any webbing you may use to contour/shape/form the foam (yes, i have a friend who's an upholsterer), in it's final desired compressed shape, and use that thickness to offset the outer surface to create the "internal boundary" of your underlying structural framing. giving some compliance for additional compression so you're not feeing the corners/edges of the frame on the surface of the finished product.

Also, make sure it'll fit through your door/window.  lol.
