• Raw edges or faces.

Make sure that selected control edges correspond with edges in your terrain.

What Is a Fence?

A Fence is a terrain edge with a special property, called Fence.

This is all there is to a Fence.

But the Fence property, while simple, allows brushes and some other Landshape commands to do powerful things. You can think of Fences as a kind of power-edge.

There are two common way of adding Fences. The first way is via Fence command. Fence uses control geometry. It is described below. The other common way is to use a point-and-click tool, called Draw Fence.

Why Fence?

Fences Guide Brush Strokes

In short, Fences are terrain edges that can tell Brushes and other Landshape operations to stop at that edge. By combining Fenced edges into a continuous path, you can create a long barrier that helps guide the action of that brush. This barrier can have any shape in plan that you wish.

When you run a brush, like Smooth brush, it can respect that fenced wall, and not bleed through it.

Fences can be very useful to accurately shape, style, and mesh terrain. Since a Fence can laterally resist your action, and stop the brush from crossing a Fenced edge, you can achieve accurate results very quickly.

Fences Can Persist

Also, Fenced terrain edges are more persistent than standard terrain edges.

When you Embed across previous standard edges, the previous edges will be removed.

However, when you Embed across Fences, the Fenced edges will remain.

Also, Fences can persist in your terrain, even when you remesh it.

By Fencing key defining features in your siteplan, you can temporarily lock them in and keep them intact, while working quickly around and across them with other tools.

Embeds and Fences Go Hand in Hand

For edges to be Fenced, they first need to exist in your terrain mesh.

You add new edges to your terrain by Embedding them.

You may embed an edge, an edgepath, or a network of edges into your terrain mesh. To do so, first select the edges, then run Embed. Fences go hand in hand with Embeds.

Embeds let you express e.g. a sharp shape transition in the terrain. Such transitions are often called for where the general terrain mesh meets a building, a retaining wall, a flight of outdoor steps, or some other built feature. Or, Embeds are used to mark the sharp border between two different terrain materials, or Zones. It turns out that it can be very useful to Fence these edges.

In practice, you always first Embed selected edges, and only then Fence them. To learn Embed basics, see the Embed command.

Since Embed and Fence so often follow each other, in the Pick toolbar, their buttons are placed right next to each other.

Autofence an Entire Plot

Sometimes, you just want to proceed quickly, and Fence your entire terrain plot in one go. Can you do this in Landshape?

😎 Pro tip — Yes, you can. To Fence your entire plot, first Select one plot and nothing else, then run Fence on this single selected plot. This will automatically Fence all Zonebounds, in other words, all edges between two materials, in your selected plot.

This trick can be useful when you have several plots in your model, and your wish to only Fence one.

Note that autofencing requires a zoned plot.

Enable Fences in Brushes

When using a standard Brush, you can set each brush to stop on Fences, by Fences, or to ignore Fences altogether.

Sometimes, Fences can be in the way. By letting a brush ignore Fences, you can work as if they did not exist. All three brush modes are useful.

To control how the Brush reacts to fences, when running a standard brush, right-click, and then select a Fencing option in its context menu.

You may also use key F6 to toggle the brush mode.

Brushes without Fences

Currently, Area Brushes do not yet support Fences. Holygon plans to add support for fences to all brushes in future Landshape releases.
