3D Terrain Modeling for Professionals

what is Landshape?

Holygon Landshape is a new Sketchup extension that introduces easy, accurate and fast 3D terrain modelling for landscape professionals.

Landshape is a unified toolsuite that helps create, edit and review terrain of any size – from tightly controlled individual sites to huge freeform landscapes.

Landshape suits landscape designers, architects, civil engineers, artists and anyone interested in creative landshaping.

Landshape is under development by Holygon and is slated for release later in 2023.

Why Landshape?

Landshape aims to achieve three user experience goals:

1. Easy — means as intuitive as Sketchup itself, letting you focus on expressing your design intent, not micromanaging the software in between.

2. Accurate — means offering precision just where you need it, with full localised control of feature sharpness, smoothness, and transitions.

3. Fast — means inviting you to explore rapid realtime workflows on terrains with millions of faces.

To help you decide if Landshape is right for you, Landshape comes with a free trial period.


Sketchup looks like a toy, but it cuts like a ninja.

Landshape takes its cue from the genius user experience that is Sketchup, and attentively applies it to terrain modelling.

This means that Landshape should be easy to learn, even for users without any previous terrain or even 3D modelling experience. It should be approachable, non-technical and fun to play with, yet powerful where it counts.

Landshape should be Sketchuppy in the best sense – the sense of 3D – that millions of Sketchuppers around the world have come to know and love.

For industry professionals, Landshape provides an unmatched level of control and workflow speed.

In short – Landshape aims for effortless landscaping expressivity for all.

Accuracy means that you are in charge of the terrain, not the other way around. Good terrain follows your design intent. 

Landshape features:
• terrain as an extendable canvas for expressing your ideas
• full control to add or remove edges or faces within the terrain, exactly where you want
• feature sharpness control, from razor-sharp to supply soft
• ability to exclude, solo, or lock any part of the terrain

Older terrain modelling solutions typically force users to end up in one of two camps: being either expressive-but-inaccurate, or accurate-but-unwieldy-and-awkward.

Landshape’s novel approach to terrain modelling enables you to be accurate and expressive at the same time.

User kindness is the best way to design beautiful terrain.

Holygon staff have been 3D modelling and developing custom extensions for Sketchup for over 10 000 hours each. Over the years, they have come to grow more familiar with leveraging the hidden power of Sketchup.

To this end, Holygon has developed a dedicated terrain geometry computation engine. It ingests, processes and outputs up to millions of terrain data points, in realtime. Its algorithms are optimised for robustness and speed. This C++ backend engine powers Landshape’s core operations.

Equally important, 10 years of hands-on Sketchup modelling experience, along with daily discussions, help Holygon to abstract away needless tool micromanagment from users, and instead focus user control into a consciously small, but carefully selected, set of interactions. These are the interactions that create most value in end users’ hands.

Effortless expressivity relies not on maximising control, but on providing the right kind of control.

By laughing in the face of adversity, challenges turn into opportunities.


You may use any Sketchup geometry to create new terrain or to edit existing terrain. 

Landshape is liberal with input. As long as you have it as geometry in Sketchup, you can use it to drive terrain expression.

As input, you are free to use any Sketchup geometry, including:

• points
• edges
• faces
• surfaces
• groups
• components

In other words, you may use:

• contourlines
• isocurves
• point clouds
• existing terrains
• a one-face rectangle
• a monster with millions of faces

Select your input geometry, pick your command, and Landshape will do the work for you.

Holygon plans to make Landshape import terrain data directly from file. Supported import file formats might include: .las, .laz .asc, .xyz, .obj, .ply, .fbx, .e57, or others.


Landshape is designed to pick up any kind of terrain, and continue from there.

Converting a previous project to a Landshape terrain is the recommended workflow.

Conversion is quick. Simply select any existing terrain geometry as input, and let Landshape create fresh new terrain right on top. It is easy to make your new terrain fit closely to the input. You may then discard your old terrain.

The new terrain surface that Landshape creates is optimised for editing with Landshape tools.

You may also use the same method midway into a project. The best workflow is the one that fits you.

With your input selected, creating or refitting terrain is one click away.

The process also allows for softness control, area filtering inputs, falloffs, and more.

Yes, as long as it is Sketchup geometry.

Landshape’s tools are intended for use on Landshape terrain geometry. Per default, landshape tools will affect Landshape terrain only. This allows you to only edit terrain while keeping non-terrain geometry visible.

For instance, you can modify the terrain right through buildings, walls and stairs, while keeping such built artifacts’ geometry intact.

However, it will still be possible to manually unlock Landshape tools for use on any Sketchup geometry, including non-terrain. This mode opens new creative possibilities for power users and daring designers.

Landshape comes as a paid extension – also known as a plugin or add-on – for the world’s best 3D modeling program, Sketchup Pro. An extension is a small program that works as a powerup. Sketchup Pro is available for both Windows and Mac operating systems. 

To run Landshape, you need:
• A computer with Sketchup installed
• The Landshape extension

Landshape should work equally well on both Sketchup for Windows and Sketchup for Mac.

Landshape should work with Sketchup version 2017 or later. Holygon recommends using the latest version of Sketchup.

For professional or continued use, you need a Landshape license.


If you are using Landshape for the first time, it will start in trial mode.

This means you can try Landshape for non-commercial purposes, for a limited time.

To use Landshape for commercial purposes, or to use it after the trial period ends, you will need a valid Landshape license.

Please note that Landshape is currently not available for download.

Thank you – yes!

Ever since Holygon’s stylized trees grew up in 2018, people have kept asking Holygon about those little ent-ities and how to place them.

Landshape makes it easy to create large swaths of terrain.

Once created, the terrain soon perceived that it was naked, and started screaming for vegetation.

Holygon is working on a solution that should at least cover the bare essentials. This solution will be announced alongside the release of Landshape.

The sidekick extension, suitable for vegetarians of all stripes, is the perfect companion for dressing up your Landshape creations in nature’s finest garb.


Landshape’s output should be 3D-printable.

Landshape keeps different parts of the terrain in different groups. Their combination should always produce one single solid.

So implicitly, Landshape terrain should always be one single 3D printable solid.

Landshape ensures that the its terrain surface is continuous, without gaps, without overlaps, without stray edges, without stray faces and without face intersections. The same is true for the togglable vertical skirt along the terrain rim.

This means that if you export the entire terrain to any standard 3D printing priming application, it is typically a one-button operation to turn the terrain geometry into a monosolid.

Or, you may always produce a monosolid manually, simply by exploding all Landshape containers and grouping the raw geometry.

Landshape exists for its users.

Your ideas help make Landshape create value for all.

As developers, we are always interested in understanding which specific terrain-related problems you most wish that Landshape should help you solve. We would also like to know how a solution would create end value for you.

You are welcome to share your ideas for possible Landshape features, tweaks, and fixes.

Please try to include any visual concepts, explanatory images, example input, example output, and full 3D models. This helps Holygon understand and accommodate your request.

We respond to every enquiry.
