You can determine information about points in a sketch by understanding how different states are represented in the modeling space. The different states of sketch points are:
- Unconnected – Unconnected points are free to move in any way within the sketch.
Connected – A connected point can indicate the following states:
- The point is connected to another sketch point. Both points will move together when modified.
- The point is connected to a line or curve with a Coincident constraint. The point can move along the line or curve or along a projection of the line or curve.
- The point is connected to the center of a line with a Midpoint constraint. The point will remain at the line's center if the line's length or position is modified.
- Locked – A locked point is fixed and cannot be moved.
You can modify the states of sketch points by adding and removing constraints. For more information, visit Adding and removing constraints.
