List of pre-defined layers and the objects assigned to that layer.
| Layer | Definition |
|---|---|
| AMC_Contour |
Maps to Objects: Contour 1; Contour 2; Contour 3; Contour 4 |
| AMC_Centerline |
Maps to Objects: Centerline; Centerline, Narrow; Hole Circle; Hole Circle, Narrow; Reference Circle for Gear Cogwheels; Reference Circle for Gear Cogwheels, Narrow |
| AMC_Break_Line |
Maps to Objects: Break Line Short; Break Out Line |
| AMC_Thread |
Maps to Object: Thread Line |
| AMC_Hidden |
Maps to Objects: Hidden Line; Hidden Line, narrow |
| AMC_Construction |
Maps to Object: Construction Line |
| AMC_Section_Line |
Maps to Object: Section/Viewing Plane Line |
| AMC_Contour_BHII | :Layer reserved to draw contours that make underlying and overlapping objects invisible in a hide situation. For example, if you place the contour of a screw on AMC_Contour_BHII layer in Content Editor, when the screw is inserted in a drawing, underlying and overlapping objects such as lines or hatches are hidden by the contour of the screw. |
| AMC_Contour_BHIU | Layer reserved to draw contours that make underlying objects invisible, and leave overlapping objects unchanged during a hide situation. For example, if you place the contour of a hole on AMC_Contour_BHIU layer in Content Editor, when the hole is inserted in a drawing, underlying objects such as lines or hatches are hidden by the contour of the hole. Overlapping objects remain visible. |
| AMC_Dimension |
Maps to Object: Dimension/Extension Line |
| AMC_Text_Medium |
Maps to Object: Text Medium |
| AMC_Contour_BHII_Invisible |
 For example, if you place the contour of a screw on AMC_Contour_BHII_Invisible layer in Content Editor, when the screw is inserted in a drawing, underlying and overlapping objects such as lines or hatches are invisible, as is the contour of the screw. |
| AMC_Contour_BHIU_Invisible |
 For example, if you place the contour of a hole on AMC_Contour_BHIU_Invisible layer in Content Editor, when the hole is inserted in a drawing, underlying objects such as lines and hatches and the contour of the hole is invisible. Overlapping objects remain visible. |
