Ratio Jump

Jumps a specified ratio along the length of an entity. This jump does not work on full ellipses and circles, as there is no meaning for start/end point.

Procedure

1. Select Tools ► Jumps ► Ratio or click the icon on the Jump toolbar. Alternatively, press [O].

2. You are prompted to:

3. Enter the ratio value between 0 and 1, and then select the radio button to indicate if the jump is on an entity or between two points.

4. Click Enter or press [Enter].

On an Entity

1. You are prompted to:

Indicate jump position

2. Position the cursor near the entity and click. The cursor jumps to the nearest "ratio point" of the nearest line that is in the "jump range".  

Between Two Points

1. You are prompted to:

Indicate first point for ratio jump

2. The snap automatically changes to the Point Snap. Indicate the first point.

3. You are prompted to:

Indicate second point for ratio jump

4. You can now indicate the second point. The cursor jump to the ratio position between the two indicated points.

The nearest ratio point is calculated from both ends of a line, so a ratio value of n is equivalent to a ratio value of 1-n. A ratio value of 0.5 is equivalent to the Midpoint jump. A ratio value less than or greater than 1 results in a jump beyond the endpoint of the relevant line, which may be useful in some situations.
