3D build animation, from one sentence

ViewGum's 3D Build is an AI maker of 3D build animations: a structure goes up part by part while a narrator says what each part does. Type what you want built, such as a bridge, a tunnel or a skyscraper, and it builds it in a 3D cutaway, with captions, music and sound effects. A 3D Build short runs 45 to 60 seconds; 45 seconds costs 450 to 550 credits, export included. You export one MP4 with post copy for each app and post it yourself.

3D Build shorts at a glance

Length
45 to 60 seconds, in 15-second steps; about 45 seconds unless you pick another. A short lands within a fifth of the length you pick.
In each short
A narrator voice, a 3D cutaway and a builder who fixes each failure with the real part, or the real method step by step. Captions, music and sound effects.
Export
One vertical 1080 x 1920 MP4 at 30 frames a second, with post copy for YouTube Shorts, TikTok, Instagram Reels and Facebook Reels. No watermark.
Credits
45 seconds: 450 to 550 credits to make, export included. 60 seconds: 550 to 650 credits to make, export included.Quoted on ViewGum's default writer on November 13, 2026.
Changes after it's made
Once it's made, ask the chat for a change to the 3D scene, such as a wider camera, a closer framing or slower moves, or redo the animation, or have a line said another way, fact checked and voiced again with the scene re-timed to it. Each change shows its price in credits before you apply it, and if one fails, the credits for work it did not do come back.
From an AI assistant
Yes, through ViewGum's connector, which quotes the price first.

How to make a 3D Build short

  1. Type what you want built, or pick one of the ideas ViewGum suggests, such as how a dam is built.
  2. Pick 3D Build. Leave it as a builder who fixes each failure with the real part, or turn on Real method to show how it is really built, step by step.
  3. ViewGum writes the script, builds the 3D scene, narrates it and renders the short. Watch it, then export the MP4.

An example 3D Build short

  • How the Burj Khalifa was built

    The tower rises over a 3D city: piles and a 3.7 metre foundation slab go into the ground, then the core climbs to the spire, 828 metres up. A muted excerpt.

Who 3D Build is for

  • Channels about engineering, construction and how things are made.
  • Topics made of parts: bridges, towers, tunnels, dams, ships, roller coasters and houses.
  • Creators who want 3D how-it's-built shorts without learning 3D software.

What 3D Build doesn't do

  • A 3D Build short runs 45 to 60 seconds, so each step of the build has time to be said.
  • The 3D is a toy-like cutaway, not photoreal footage.
  • It suits things made of parts. A topic with nothing to build fits an Explainer or a narrated faceless short better.
  • It does not post for you. You get the MP4 and post copy for each app, then post it yourself.
  • It does not cut clips from long recordings.
  • It does not export horizontal or square video.
  • It does not have a public REST API. AI assistants connect through its MCP server.

Questions

How do I make a 3D build animation?

Type what you want built, such as a suspension bridge, and pick 3D Build. ViewGum writes the script, builds it part by part in a 3D cutaway, narrates it and adds captions, music and sound effects. A 3D Build short runs 45 to 60 seconds.

Can I make a 3D build animation without Blender?

Yes, for a narrated short about how something is built. 3D Build makes the 3D scene and renders it for you, so there is no 3D software to learn. To animate a model you made yourself, you still need 3D software such as Blender.

Can AI show how a skyscraper gets built, step by step?

Yes. Pick 3D Build and turn on Real method, and the short shows how it is really built, step by step, with no gags. Left off, a builder tries a crude version first and fixes each failure with the real part.

How much does a 3D Build short cost?

On ViewGum's default writer: 45 seconds: 450 to 550 credits to make, export included; 60 seconds: 550 to 650 credits to make, export included. Creator is $49 a month for 4,500 credits, Pro is $99 a month for 9,500 credits and Studio is $199 a month for 20,000 credits. Every 3D Build short shows its price in credits before it starts and is charged what it used, never more than the top of its range.

Can I make a 3D Build short from my AI assistant?

Yes. Connect ViewGum to your AI assistant once, then ask it for a 3D Build short on your topic. It shows you the price and waits for your yes before anything is charged.
