Use this when you want to place a set number of points along a line within a flow, for example distributing units or access points evenly across a frontage.

Category: Dendrogram

Kind: Operation

Description: Legacy dendrogram node for along point

Inputs

This node runs in Transform mode by default, so its settings come from the paired Transform node through the T connector. You can't wire a value straight into a single setting. To drive one setting from your flow, override it with a Write Property node between the Transform node and T, or switch this node to Exposed Inputs to get a connector for each setting.

How to:

Feed in a feature
The feature could be a rectangle, polygon, or line
Add the Along Point Transform node and connect its output to the Along Point node's T connector.
1. Click “Edit Defaults” to set the starting values for the flow
Edit the settings in the Properties Palette
- Add or remove points
- manually adjust point distribution or use button presents
- Toggle whether the output rotates to the line orientation
The output is a list of points

Connect the Along Point Transform node

The Along Point node needs the Along Point Transform node connected to its T connector to use your settings. Without it, the Along Point node runs on Giraffe's built-in default settings, and you can't change any of them in Edit Defaults or the Properties Palette.

Use the exposed inputs version of the Along Point node, which has its own connector for each setting and needs no transform node.

Along Point Transform settings object

The Along Point Transform node creates a set of inputs in the Properties Palette for anyone using the flow to fill out. It converts those inputs into a plain JSON object and sends it to the Along Point node through the T connector. The object has type set to alongPoint and the settings inside parameters. The values below are the built-in defaults.

{
  "type": "alongPoint",
  "parameters": {
    "percentsAlong": [
      0.5
    ]
  }
}

The Along Point Transform settings in the Properties Palette show lengths, areas, and volumes in your project units. The JSON always stores them in meters, square meters, and cubic meters, so a value you write into it with Write Property must use those units too.

To drive one setting from elsewhere in your flow, override it with a Write Property node. Put Write Property between the Along Point Transform node and the T connector, and set Property to a path like parameters.percentsAlong.

Use the Along Point node with exposed inputs

The exposed inputs version of the Along Point node has its own connector for each setting, so you can wire values straight in without a Along Point Transform node.

Right-click the Along Point node and choose Expose inputs. Giraffe replaces it with the exposed inputs version.
Connect your input to the Features connector.
Type a value into each setting on the node, or connect a value to its connector. A Number node, a value from another node, or an Input Parameter all work.
To let people using the flow change a setting in the Properties Palette, connect an Input Parameter to it. Settings without an Input Parameter stay hidden.

To get the exposed inputs version every time you add a node, turn on Show exposed inputs when creating new nodes (the gearbox icon) in the flow editor toolbar. Settings don't carry over when you switch between versions.
