# Model Editor Parameters

Parameter | Description
--- | ---
Occurrences | Specifies how many instances of a model should be detected. When set to -1, the tool will detect all models.
Threshold | Specifies the lowest score allowed to be a match for the model.
Search Space
Angle | Specifies the possible orientations the model may exhibit.
Scale | Specifies the amount of deviation in the overall model size, and in the deviation of inter-node spacing, that will be allowed for a match. For example, a value of [0.8, 1.2] would specify that the overall size of the model must be between 80% and 120% of the nominal size, and the spacing between any two nodes in the model must also be between 80% and 120% of the nominal spacing.
Aspect-Ratio | Specifies the amount of deviation in the overall model aspect ratio, and in the deviation of inter-node ratios, that will be allowed for a match.
Shear | Specifies the amount of deviation in the shear mapping of the model, and in the deviation of inter-node shearing, that will be allowed for a match.
X | The X and Y parameters specify the search region within the View, expressed in percentage terms. For example, to search only the upper-left quadrant of a View, you would specify [0%, 50%] for both X and Y. With these settings, only model matches where all of the nodes lie within the specified region will be returned. In the example shown below, A is matched, but B is outside of the X and Y range, so it is not matched with A to form the A-B model.
