4Prot Build anything from a thousand blocks

The core of 4Prot is simple: tiles and block-type objects that snap together into prototypes of processes and 3D models. A menu gives you more than 1000 blocks and bricks to choose from, and each one can be adjusted: move it, recolor it, resize it, reshape it to fit what you need.

That means a mockup can be as rough or as detailed as you want. Stack a quick layout to sketch an idea in ten minutes, or keep refining the same model until every piece sits where it should. There is no timer and no way to fail; you build at your own pace, which makes it an easy place to think out loud in three dimensions.

A finished prototype does not have to sit still. 4Prot lets you build an animated presentation out of multiple scenes, so you can walk an audience through a process step by step instead of pointing at one static model.

You add smart cameras and actors to the presentation, deciding where the view goes and what moves through the scene. For teaching or pitching, that is the difference between describing a warehouse layout and actually showing someone a forklift crossing it, scene by scene, in the order you choose.

Projects in 4Prot can be worked on in online multiplayer sessions with your Steam friends, so a prototype becomes a shared table rather than a solo desk. Set up your team, open a session, and everyone builds on the same model at once.

That fits the way the tool is meant to be used: collaborative work between students and university professors, or colleagues sketching a logistics flow and arguing about where the bottleneck is while the blocks are still in their hands. If you want a low-pressure place to build alongside other people, this is it.
