Nurbs Object
The NURBS Object in Architron is an implementation of Non-Uniform Rational B-Splines (NURBS) within Cinema 4D, serving as the foundational element for all parametric objects in the plugin. Derived from the Cinema 4D geometry object, it encompasses a comprehensive suite of NURBS geometry capabilities.
This object provides users with standard editable curves, surfaces, and polygons, making it a versatile tool for detailed architectural modeling. In the current version of Architron, the NURBS Object supports editable NURBS curves and non-editable parametric NURBS objects, providing a focused and specialized toolset for architectural visualization.
Key Parameters:
NURBS Object Parameters
Object
Output Geometry: Switch between 'Curves' and 'Surfaces' to specify the NURBS output.
NURBS Detail: Adjust the level of detail for NURBS geometry; higher values yield more detail.
Fix to Parent: Ensures the NURBS object's position matches that of its parent when active.
Object Workplane: Dropdown menu for selecting the object's ground axis orientation.
2D Object: When enabled, this parameter affects the UCS (User Coordinate System) and tool behavior, generating UCS based on the selected Ground Axis.
Flatten 2D Object: Flattens the geometry for use as a 2D object.
Import NURBS: Imports NURBS data into the object from a specific file format.
Export NURBS: Exports NURBS data from the object into a specific file format.
Analyze NURBS: Activates additional visualization tools for assessing geometry indexes and properties, useful for in-depth analysis.
Analyze
Show Point ID: Displays the identifier for each control point in the NURBS geometry.
Show Edge ID: Enables visualization of the identifiers for edges in the model.
Show Element ID: Displays identifiers for individual geometric elements.
Show Iso Points: Toggles the visibility of iso-parametric points, which are points of constant parameter on curves or surfaces.
Show Knots: Displays the knots of the NURBS curve or surface. Knots are points that define the division of the curve or surface and influence its shape.
Show Knot Values: Displays the numeric values associated with the knots in the NURBS geometry.
Show Inflection Points: Identifies inflection points where the curvature of the NURBS curve or surface changes sign.
Show Open Curve Ends: Highlights the ends of open NURBS curves for clarity.
Show Loop Disconnections: Toggles the visibility of disconnections in looped NURBS curves, useful for troubleshooting complex geometries.
