Explaining is billable time. Patent agents, attorneys and drafters charge by the hour, and a lot of that time goes to understanding what your invention is. Arriving with a numbered drawing and a 3D model you can turn can mean fewer explanation calls and fewer rounds of revisions.

Concept drawings, not formal patent drawings
Try the sample model

Turn it, zoom in, take it apart.

This is the 3D model from the Clip-On Tent Lantern sample, the same viewer you get with a Design Set. Each numbered part is its own piece. Spread the parts to see how they fit, or see inside to find the battery pack (03).

The figure sheet

One angle, or every side.

Both come with a numbered figure sheet. The Design Set's sheet is made from your 3D model, so it shows every side and how the parts come apart.

Built for your shape

Five ways to build, picked for you.

We read your sketch and parts list, pick the build that matches it best, and show you which one we used and why.

How your model is built
Design Set · $39.99
Measured parts
Boxy, engineered designs with flat faces, slots and catches. Choose “Guide me” to check each part, or “Build it for me.”
Included
Drawn shapes
Round products like lamps and bottles, each part drawn as one smooth shape.
Included
Soft shapes
Shoes, grips, wearables and other cushioned things, built from rounded forms that blend where they meet.
Included
Soft surfaces
Jackets, gloves, bags and tents: a thin fabric layer over the shape it wraps, with seams and pockets.
Included
Freeform
One flowing, sculpted surface, like a mouse or an ergonomic handle, carved from your sketch’s own outlines.
Included
Easy editing
Move, resize and nudge parts, accept suggested fixes, change fabric thickness. Edits are free and every version is kept.
Included
Clothing is a 3D look-and-fit model, not a sewing pattern

What this is not

  • Not a formal patent drawing. The USPTO has strict rules for those, and a drafter can prepare them starting from yours.
  • Not a patent application, and not legal advice.
  • Not a judgment of your idea. We don’t score it. We draw it.
  • Not a subscription. You pay once per invention.

Questions

No. These are concept drawings, not formal patent drawings. They show your invention clearly with numbered parts, and a patent drafter can prepare formal drawings from them. Check every detail yourself before anything is filed.
