On the Tools menu click Snaps to select Percent Along when the command prompt requests a point to use this modifier.
PERCENT ALONG selects a point at a specified percentage of the reference entity’s length. For most referenced entities, PERCENT ALONG treats the nearest endpoint from the selection point as its beginning. For example, 75% of a line is three-fourths of the way along its length, starting at the end nearest the selection point. As with all modifiers, you must first select a drawing or editing command. The prompt reads "% value [0%]:". Enter a number. For example, to select a point 1/4 of the way along a line, type 25 and press ENTER. Now the prompt reads "Select reference entity:". Select a point on the entity you want a percentage of (remember that the selection point on the reference entity controls which end CC3 starts from when calculating the percentage distance). You can use percentage values less than 0% or more than 100% on some entities. For example, you could use 125% to select a point 1/4 of the way beyond the end of a line.
