DIST (distance) allows you to calculate the actual and
projected distance between two positions, a position and a
geometric entity, or two geometric entities.

Identify the type of distance verification by choosing 
from the following menu:

2 POS   - to calculate the minimum distance between two 
          positions on the screen.

POS+ENT - to calculate the minimum distance between a 
          position and a selected geometric entity.

2 ENTS  - to calculate the minimum distance between two
          selected geometric entities. Select the first 
          curve entity by positioning the cursor and 
          pressing the space bar or cursor button. 
          Select the second curve in the same manner.
