How do I model these shapes on a sofa?

I need to model the shapes that is on this sofa:

I got my pillow ready:

The egdes looks like this:

What have you tried so far?

I or someone else could give you step by step instructions, but it's better for you to learn the "why's" rather than just the "how's".

Think about the shapes. What two primitives could be combined to make this work?

Hi, for some reason the solution just popped out in my head :P

Hey,

not sure from the description where/if you're stuck, but I hope this helps:



Right now, your sofa has a lot of hard edges. This can be solved by adjusting the bevel radius of your pillows. It also looks like you beveled the base cube first and then scaled them which is suboptimal. Do it the other way round, that way your rounded edges should be uniform.

I found a wireframe image of what I need to do. .
But the polygoncount is way to high (46,429), so Im going to model one myself. It
dosent seem too hard to add a cube, scale it, add divisions and then move the egdes around for
the desired shape.

That sofa was done with subdivision surfaces. This is a great technique to learn, often used to make game art (normal maps, etc.). We have many resources to help you learn.

Thanks for the link, will have a look Im modeling interior models for archviz, so I dont want too many polygons.

Eric Chadwick

Subd is perfect for archviz. I do some archviz too, and nothing is faster for making furniture and other architectural models.

I took it into 3D Coat and smoothed out the cornes. And back into MayaLT for .fbx export:



UnrealEngine render:




I know the shadows is abit wierd, but I just imported it for testing purposes. What do you think?

It's a good start. It needs to look more like a sofa though. It doesn't match the first image you posted. Do you have a photo of a real couch?
