# Sketch Driven Component Pattern

Sketch Driven pattern is to place the instances according to the sketch point array in the sketch, and copy the instances according to the set distance. Its command interface is shown in the figure below.

Sketch Patterns can pattern instances in both directions, and if a sub-instance is selected in a viewport, the top-most instance where it resides is still patterned. The description of each control is as follows :

Components: Pick the components that need to be patterned.
Sketch: Pick a sketch that contains points.
Reference Type: There are two options, "Bounding Box Center" and "Specified Point".
Reference point: When selecting "Specified point" for the reference type, you need to select a point as the reference point.

Example： An instance and a sketch with multiple points.

Array the instance at each point on the sketch, and after setting the parameters, the effect is as shown in the figure below.

Click "OK" to complete this operation, and the created effect is shown in the following figure.
