Defining an A and a B side
Surface finishing often leaves aesthetic defects on your parts, such as hang marks for anodizing. Defining an A- and a B-side in your design will ensure that the most important areas of your part remain free of defects.
In this image you can see how you can define an A-side and a B-side in your technical drawing:
A side: Indicates the most aesthetically important surface, typically the visible side of your product.
B side: Indicates the side that is not aesthetically important, typically the side hidden from visibility after assembly.
For the primary surface (A-side) of your part, we guarantee defect-free production. In contrast, secondary surfaces (B-side) may be machined with hanging marks and other minor defects. B-side surfaces, like the rest of your part, will be free of scratches, stains and blemishes.
| Will my part have | Primary surface (A-side) | Secondary surface (B-side) |
|---|---|---|
| Scratches, stains, blemishes | No | No |
| Hanging marks | No | Minor hanging marks |
| Other minor defects | No | Up to 2 minor defects |
