Use this when you want to round or chamfer the corners of a polygon or line within a flow, for example producing smoother boundary geometry or architectural chamfers.
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.

The fillet curve node is only for adding curves within a flow. Use the Corner Type property to change the corners (Fillet, bezier, or chamfer) of a geometry without flows. Add it from the Property Palette.
How to:
Draw a Line , Rectangle or Polygon
Click “Open flow builder”
Add the round corners node and connect the round corners transform
Click “edit defaults” to set the starting values
Edit the settings and outputs in Properties
Round Corner Settings
Using the Round Corners Transform, all settings automatically appear in the properties palette.
Adjust the settings as required.
Edit corner Radius - change the distance of the corner radius
Select the corner type - Fillet, bezier, or Chamfer corners
Fillet: evenly round corners | Chamfer: Slice corners at 45 angle | Bezier: unevenly round corners by dragging node |
Adjust which corners receive the radius
Round Corners Output
The output is a shape with transformed corners.
Often used for roads to add turning radius.
