Organic shapes with the agent

Some things are all about precision: a bracket, an enclosure, a gear. Others are all about the form: a computer mouse that fits your hand, a vase with a twist, a pebble paperweight, a little bird for the shelf. Solid Vibes builds both, and the agent picks the right way for each request on its own.

Three ways to build

For every request, the agent first decides how the thing should be modelled:

• Classic. Functional, precise parts made from sketches, extrusions, holes and rounded edges. Brackets, boxes with lids, gears, wall mounts, spacers, clips, hinges, knobs, hooks, phone stands. These stay classic, even if you ask for smooth edges.
• Organic. The form is the design. The agent sculpts a smooth body, like clay, or makes a flowing shape through a few cross-sections. A mouse, a vase, a toy figure, an ergonomic grip, a wavy bowl, a lamp shade, a chess pawn.
• Hybrid. A smooth form that must also hold real parts. The agent sculpts the form first, then adds precise features on it: screw posts, a USB-C cutout, button holes, a battery cavity, a flat base. A pebble-shaped speaker, a controller with buttons, a lamp with a socket.

You can see which one it chose in the agent trace. Every organic shape ends up as a normal solid, so holes, rounded edges, exports, the printability check and slicing all work on it.

What to ask

Say what it is, how big it is, and how it should feel. Words like smooth, flowing, ergonomic, sculpted, curvy or like a pebble tell the agent the form matters.

Make me a smooth ergonomic computer mouse, 120 mm long.

A tall vase with a twisting, flowing shape, about 220 mm tall, open at the top.

A pebble paperweight, smooth and heavy-looking, palm size.

A bird figurine for my shelf, about 80 mm tall.

For a hybrid, name the parts it must fit:

A pebble-shaped Bluetooth speaker housing for a 40 mm driver, with a USB-C port at the back and four screw posts inside.

An ergonomic computer mouse with a USB cutout at the front and a battery compartment underneath.

Shaping it further

Ask for changes in plain words. The agent reshapes the existing body instead of starting over:

Make the back of the mouse a bit higher and slim the middle where my thumb goes.

Give the vase a narrower neck and a crisp edge at the rim.

If you want a classic part to look softer, say so ("make this bracket smooth and flowing"). If you want an organic request built the precise way, say that too ("keep it geometric, flat faces only").

Printing organic shapes

Rounded shapes rarely have a flat side, so they rock and need supports. The agent adds a flat base (it cuts the bottom flat by a millimetre or two) and tells you to print it standing on it. If a proposal still has no flat base, the preview card says so, and you can ask:

Give it a flat base so it sits on the print bed.

Organic overhangs under about 45° print without supports. Steeper ones (the underside of a bird's beak, a mouse's front lip) may need supports; the printability check in Make shows where.

From a concept to a sculpted model

When you hand a concept from the Concept Board to Build and its form is organic, the agent:

1. reads the outline of the subject in the front, side and top views of the turnaround sheet,
2. builds a starting shape that matches those three outlines at your real dimensions,
3. sculpts from it and adds the flat base and any precise features,
4. checks the result: it compares the model's outlines with the sheet's and shows how closely they match. Below 82 % it makes one more pass to fix the biggest difference ("the back is too slim in the side view").

See Why concept images are intent, not geometry for how the real sizes and the image work together.

Costs

Organic builds cost the same as any other build: a new model is a multi-step build, and a change to it is an edit. The outline check after a concept hand-off is part of the normal visual check.

Limits

• The agent sculpts from a small set of starting shapes (pebble, capsule, soft box, ring, bottle, mouse body, handle loop, stand). Very detailed forms, such as faces, fingers or lettering on a curved surface, come out simplified.
• Outlines are read from the turnaround sheet's white background. Busy or shadowed sheets fall back to a rougher outline from the image description.
• Thin organic walls can print poorly. Keep walls at least 1.6 mm, or ask for a solid body.
