Input ports

NameTypeDescriptionDefault Value
Center
Point
The circle or arc center point {x, y, z}. Defines the midpoint of the measured diameter.
Direction
Vector
A vector that defines the orientation of the diameter line. The node uses this direction to position the dimension text and arrowheads symmetrically across the circle.
Diameter
Number
The measured diameter length. The node can receive this directly or calculate it from geometry.
Offset
Number
The distance between the dimension line and the label text, measured along the radius direction.1.5
Decimals
Number
Integer [0–6] (default: 2) Number of digits after the decimal point when formatting the numeric value.2
Suffix
String
The unit or text appended to the numeric value.mm
Override
String
Custom label template. If contains {val}, it is replaced with the formatted value. If does not contain {val}, the text is displayed exactly as provided.
Mark
Boolean
When enabled, a small cross mark is drawn at the center point to indicate the geometric center of the circle or arc.
Style
Meta
Defines visual styling of the leader line, arrow, and text.

Creation method

[comment]: <> ()

There are two options for creating a Diametrical Dimension node.

  • The first way to create a Diametrical Dimension node using the search list, which is opened by double left-clicking in the workspace. You can write the name of the node you need, or words associated with this node.
    • diameter, diametrical, dimension, measure, circle
  • The second way is to select a Diametrical Dimension node from the menu that opens from the top left.
    • Menu > Dimensions > Diametrical Dimension

Steps

  • Create a Diametrical Dimension node.
  • Connect the center point to the center port.
  • Connect a direction vector to define the diameter direction.
  • Connect the diameter value to the diameter port.
  • Optionally, connect a Dimension Style node to customize appearance.

The Diametrical Dimension node measures and visualizes the diameter of circles with professional dimension lines, arrows, and center marks. It automatically calculates the diameter and displays it with customizable labels.

It outputs the following values:

Curve - Drawable dimension graphics with arrows and center marks

Diameter - Numeric measured diameter value

Center Point - Center point of the circle

Works with circular geometry and provides professional CAD-style diametrical dimensioning with customizable arrows, labels, and styling. Includes center mark for better visualization.
