Profile Surface controls how far selected faces may deviate from their ideal three-dimensional surface. Use it for contoured surfaces, molded faces, aerodynamic surfaces, castings, and other features where the whole surface shape matters.

Profile surface GD&T annotation on a selected face

Faces

Select one or more faces to control. Profile Surface applies across the selected surface area, not just a single boundary edge.

Tolerance

Set the allowed deviation from the ideal surface in the current unit system.

Datums

Add datum references when the surface profile should also control orientation or location relative to a datum reference frame. Leave datums empty when the profile controls only form.

Precision

Choose how many decimal places to display in the annotation.

Frame Position

Place the feature control frame relative to the leader arrow. Keep the frame clear of dense model details so it remains readable.

Frame Plane

Choose the display plane for the feature control frame. Use the plane that keeps the annotation facing the viewer in your documentation or inspection workflow.

Leader Scale

Adjust the visual size of the leader dot.

Font Size

Set the model-space height of the annotation text.

Zoo Design Studio writes KCL behind the scenes. A Profile Surface annotation uses gdt::profileSurface with one or more selected faces, a tolerance, and optional datum references.
