3D Protrusion Modeler

Turn your drawn line into a rotating 3D model

Open Tool

Overview

The 3D Protrusion Modeler is a free browser tool that converts a line drawn on the screen into a rotating 3D wireframe model.

The line changes shape as it becomes three-dimensional, and the finished model rotates in the center of the screen.

No installation or sign-in is required. It works on smartphones, tablets, and computers.

How to Use

  1. Press “Open Tool”.
  2. Trace any line on the black screen with your finger or mouse.
  3. Release your finger or mouse to convert the line into a 3D model.
  4. Draw another line to create a new model.

Lines That Work Well

Draw one line with a reasonable length. A short tap or an extremely short line will not be converted.

The length, curves, and positions of the start and end points affect the final 3D shape.

Start Over

Press “Reset” to clear the drawn line and 3D model and start again.

Secret Trick: Transform into a Rocket

After the 3D model finishes transforming, briefly tap or click the screen to change it into a rocket-like shape.

Moving while pressing is treated as drawing a new line, so press briefly without moving much.

Ideas to Try

  • Compare straight lines, waves, and spirals.
  • Try long and short lines to see how the size and shape change.
  • Draw similar lines repeatedly and observe how the models differ.
  • Transform a finished model into a rocket.
