# Create an Advanced Recipe with Multi-Pattern

Multi-Pattern mode allows users to specify backup patterns (PartIDs). If the primary part has not been found, the system will automatically try to locate the backup parts instead in order to produce a valid alignment result.

In the Advanced Recipe Settings, select the Multi-Pattern tab. Here you can select the order of the backup patterns. The default setting is when there are no PartIDs selected as shown below.

: The number of Available partIDs on the Multu-Pattern tab depends on the selected recipe configuration on Genaral Tab, but the maximum number of PartID that you can set for Multi-Pattern is 4. All PartID fields do not needs to be set.

When 4 features are selected in General, you will have up to 6 PartIDs to choose from in the combo box. PartIDs 5 and 6 represent two parts, with two features on each part.
