KeyTray Andamia
Alpha version

Sketch, draft and build
from one file.

KeyTray Andamia brings together what SketchUp, AutoCAD and Revit do today: model in 3D, draft precisely in 2D, document the house with its drawing set and present it with realistic rendering. The same project opens in the browser and in the desktop app.

Three programs, one model

Every tool works on the same document: what you draw in plan shows up in 3D, in sections and on sheets, without exporting or redrawing.

1

3D sketching

Push/pull, soft and hidden edges, solids, components, Match Photo, geolocation and terrain. Opens and saves SKP through the installed SketchUp.

2

Precise 2D drafting

AutoCAD commands and shortcuts (F3, F7, F10…), MTEXT, dimensions, layers, hatches, tables and plotting to PDF. DWG and DXF round trip.

3

BIM and drawing sets

Walls, slabs, roofs, straight and curved stairs, typed doors and windows, area and room schedules, sheets with title blocks, revisions and IFC.

4

Realistic rendering

GPU path tracer with sun and sky, glass and light fixtures; vegetation, people and video walkthroughs. A clean image in seconds, up to 8K.

5

Web and desktop

The same application runs in the browser (WebGPU) and as a Windows program. The core is C++ compiled to WebAssembly: fast in both.

6

Teaches as you work

Every command has a learning card: what it does, how to use it and what it asks for. One program from student to professional, with the same file.

Built for each country's building code

The core is global and each country comes as a versioned package. We start with Peru (Reglamento Nacional de Edificaciones): Peruvian area schedule, title block and permit sheets. The Peruvian package rules are a draft: licensed architects and engineers (CAP / CIP) complete them before they are considered valid.

System requirements

Measured on this version, not estimated. If your laptop is a few years old, use the desktop app.

Desktop app (recommended)

  • Windows 10 or 11, 64-bit.
  • Microsoft Edge WebView2: included in Windows 11; the installer adds it if missing.
  • A graphics card with Direct3D 12. On laptops with two GPUs it picks the dedicated one.
  • Older GPUs without Direct3D 12 (for example Intel HD 4600) run in Direct3D 11 mode with automatic quality.
  • Measured on a 2014 laptop (i7-4700HQ, GTX 860M): 1.57 M-triangle urban model at 56 fps; on its Intel HD 4600 through Direct3D 11, 50–54 fps.

In the browser

  • A browser with WebGPU: recent Chrome or Edge on Windows with a Direct3D 12 GPU.
  • A secure connection (https): WebGPU does not work without it.
  • GPUs without Direct3D 12 have no WebGPU in the browser: the program detects it, explains why and recommends the desktop app.
  • The public web app is not open yet: for now, use the desktop app.

Windows installer digitally signed by SoftControl Enterprise Inc.

The signed installer of version 0.2.0 will be published here in the coming days. Write to us and we will let you know.

This is an alpha version: keep copies of your projects. Installing a new version uninstalls the previous one; your .andamia files are not touched.

What's new

SketchUp parity

Soft and hidden edges, solids, sandbox, Match Photo, geolocation, 3D text with TrueType fonts; axis locking with arrow keys, texture pins, OBJ, GLB and DAE import with textures.

AutoCAD parity

In-place MTEXT editor, tables with formulas, MULTILEADER, text and dimension styles in DWG, annotative objects, CTB on sheets, associative hatch, PDF import and publish.

Revit parity

Multi-flight, winder, spiral and curved stairs; skeleton roofs; curtain walls; Peruvian area schedule, revisions, title block, field schedules, links, IFC with Psets and 15 families.

Rendering and presentation

WebGPU path tracer, HDRI sky, panoramas, 8K in strips, video walkthroughs, cameras, styles, fog, depth of field, IES lights, grass, decals and an exportable web page.

Files and daily use

Recovery after an unexpected close, properties palette, quick select, match properties, find, command aliases and Ctrl+K.

Low-end laptops

The app picks the dedicated GPU, recovers when the graphics driver resets and adjusts quality on its own to stay above 30 fps.

Not there yet

  • Opening and saving .skp files needs SketchUp installed plus a component this installer does not include yet.
  • The Peruvian building-code package is a draft until licensed professionals review it.
  • The public web app and the online content library come in a later version.
