Distance captures a dimensional tolerance for an edge length or for spacing between selected faces and edges. Use it when a model-based definition needs the measured value to remain attached to the 3D geometry instead of living only in a separate drawing.

Distance GD&T annotation on an edge

From And To

Select a starting face or edge and an ending face or edge when the annotation should measure spacing between two entities. from and to must be used together.

Edges

Select one or more edges when the annotation should display edge length. Edge selection cannot be combined with from and to.

Tolerance

Set the acceptable distance variation in the current unit system.

Precision

Choose how many decimal places to display for the measured distance and tolerance.

Frame Position

Place the distance label relative to the selected geometry.

Frame Plane

Choose the display plane for the distance annotation.

Leader Scale

Adjust the visual scale of the distance arrows.

Font Size

Set the model-space height of the annotation text.

Zoo Design Studio writes KCL behind the scenes. A Distance annotation uses gdt::distance with either edge selections or a from / to pair.
