PROFILE DEVELOPMENT / 10A
10A middle concave
10A Center-Notched: Center-notched sample record. The notched section must be described together with the two side solids. During review, the slot opening, slot bottom, and transition fillet shall be individually specified—avoid defining the section solely by overall width and height.
Geometric Focus Points
Depth of recess, fillet radius at the slot bottom, and thickness on both sides
Concave contours, transition fillets, and section symmetry

Cross-sectional features and review points
The center-notched section must be described together with the two side solids. During review, the slot opening, slot bottom, and transition fillet shall be individually specified—avoid defining the section solely by overall width and height.
Drawings and measurement requirements
Recommend specifying the depth datum plane for the notch, measurement locations for side thicknesses, and whether left-right symmetry is required; contour inspection must correspond to these datums.
Delivery and subsequent processing
If mating or positioning requirements exist, provide mating part contours and contact locations, distinguishing functionally critical surfaces from adjustable transition zones.
Documentation basis and scope of confirmation
Data originates from this case’s catalog and internal sample photographs; catalog dimensions are nominal values, and photographs do not substitute formal inspection reports. Material standards, mechanical properties, heat treatment, supply conditions, and acceptance criteria must be confirmed per project.

Development Q&A
Which dimensions must be clarified first for center-notched cross-sections?
First clarify overall width and height, then separately define notch opening, depth, bottom fillet radius, and side thicknesses; envelope-only dimensions cannot fully describe the notch.
How is the measurement datum for the notch specified?
Mark the depth datum plane, cross-sectional orientation, and sampling location on the drawing, and confirm whether bilateral symmetry verification is required.
