You can attach a datum feature symbol to the following items:
- In a part or assembly, on a planar model surface or on a reference plane
- In a drawing view, on a surface that appears as an edge (including silhouette edges) or on a section view surface to identify datum planes in the part
- A geometric tolerance symbol frame
- In a note
- On a dimension, except for:
- Ordinate dimensions
- Chamfer dimensions
- Angular dimensions (unless the symbols are displayed per the 1982 standard)
- Arc dimensions
You can also drag and drop datum feature symbols onto existing dimensions and geometric tolerance frames.
