An aperture (or its inverse) defined by (x, y) points in an SDDS file.

| Parameter Name | Units | Type | Default | Description |
| L | M | double | 0.0 | length |
| TILT | RAD | double | 0.0 | rotation about longitudinal axis |
| DX | M | double | 0.0 | misalignment |
| DY | M | double | 0.0 | misalignment |
| DZ | M | double | 0.0 | misalignment |
| RESOLUTION | M | double | 0.0 | z resolution of finding intersection |
| INVERT | short | 0 | if non-zero, contour defines an obstruction rather than an aperture |
|
| STICKY | short | 0 | if non-zero, effect persists in downstream elements until canceled or replaced |
|
| CANCEL | short | 0 | if non-zero, sole effect is to cancel previous sticky APCONTOUR |
|
| FILENAME | STRING | NULL | name of file containing contour data |
|
| XCOLUMN | STRING | NULL | name of column containing x data |
|
| YCOLUMN | STRING | NULL | name of containing y data |
|
| GROUP | string | NULL | Optionally used to assign an element to a group, with a user-defined name. Group names will appear in the parameter output file in the column ElementGroup |
|
The STICKY parameter results in the aperture contour being applied inside subsequent CCBEND, CSBEND, CSRCSBEND, KQUAD, KSEXT, verb—KOCT—, and KQUSE elements, as well as at the end of other downstream elements. This continues until another APCONTOUR element asserts a new contour, or uses CANCEL=1 to cancel the feature.
