BeamDown Quick-Start Guide

BeamDown Quick Start Guide


Thanks for joining us as a BeamDown user! This is an evolving platform that we aim to grow and implement new features. We’ve designed BeamDown to be intuitive and for users to be able to build custom terrain with very little introduction and zero 3D modelling experience.

As a brand-new platform, you may encounter some minor bugs as we expand the functionality and asset library.

Latest News

We’re working on a LOT of new BeamDown features behind the scenes. Below are the features current in development:

  • Asset Store (for smaller packs & more sets)
  • Project Sharing
  • Back-end user management systems

Please see the Dev Roadmap for more.

Basic Usage Guide

Key Principles

All assets are accessed from the pallet on the right hand side:

From the palette:

  1. Click a set
  2. Click a subheading to expand it
  3. Select an asset

When in BUILD MODE, There are TWO main building methods. these are specific to the set being used:

Freeform Builder

Drag and drop from the pallet to the build platform. Compatible parts will highlight GREEN & SNAP.

BeamDown Freeform

Used in the ‘Sci-fi Building Generator’ set

Quick Frames

Frames and roof sections are dragged from the pallet to the build platform.

BeamDown QuickFrames

Used in sets such as ‘Grid City’, ‘Modern Buildings’ and ‘Desert Houses’.


Freeform items can be snapped to compatible objects – You should never need to ‘manually’ attach objects. To automatically connect objects such as walls and floors :

  1. Drag an item from the palette
  2. Compatible objects will now display snap points (glowing white orbs)
  3. Hovering over a snap point will turn green to indicate it will connect
  4. Use the Q & E keys to rotate the object
  5. Click to attach the objects.
Snapping points

Mount Points

Once Freeform or Quick-Frame objects are placed on the build platform, you can select them to display ‘mount points’.

Black dots are mount points – Hover over a mount point to see what can be attached to it. Click it to display all compatible components in the palette. Click the component in the asset to attach it. Attached objects may have their own mount points to.

SELECTING SIMILAR MOUNT POINTS – Click on a mount point twice to select all similar Mount Points on that selection.

  2. Ensure the ‘Build’ mode is active at the top of the screen
  3. Using the palette window on the right hand side, click on a set (EG ‘Grid City’), then click a title such as ‘Frame’ or ‘Wall’. This will show you all of the assets for that category.

  7. Drag items onto snap points from the pallet – Hover your mouse over the white orbs until they turn green.

Floorbuilder (Freeform)

Sets using the Freeform builder such as the ‘Sci-fi Building Generator’ can use the Floorbuilder which automatically adapts to the connected wall shape so that you build conforms to a 1in grid.

  1. Within a compatible set, select the Floorbuilder from the palette
  2. Drag your chosen floor style onto the build plate or snap to a compatible wall (it will turn green when snapped)
  3. The floor model will adapt to the snapped wall – Use the Q/E keys to rotate the floor and R key to change it’s theme
  4. Some floor pieces can be selected when placed to mount additional details

Note – Floor models have different styles and sizes
