# Gap between a Curve and a Surface(Distance)

Gap between a Curve and a Surface(Distance) command evaluates gaps between a curve and a surface. Discrete points on a curve are selected to get the closest point to a surface. Then if the distance is less than a threshold, the distance values are depicted on the screen.

## Step 1

For the prompt "Specify a curve", select a curve to evaluate.

## Step 2

For the prompt "Specify a surface", select a surface to evaluate.

On the surface selection, the command will evaluate the gaps and dipicts the distance values and lines that connect the closest points.
