snap distance

This tool allows you to snap to a point that is between two points, or a given
distance from the first point, at an angle defined by the second point.
It includes a snap distance box and a drop down combo box. The combo box
has three options - 'Distance', 'Percent' and 'Fraction'. So if you entered
50 percent or a fraction of 0.5, for example, it would retuen a point exactly
half-way between the two points.
You enter the value in the snap distance box, and then choose 'Distance',
'Percent', or 'Fraction' from the drop down box.
This command does not restrict the distance, percent or fraction entered.
Therefore a distance greater than the distance between the two points will
return a point beyond the second point. Similarly a percentage greater than
100, and a fraction greater than 1 will return a point beyond the second point.
You can also enter a negative value. This will return a point before the first
point. (Note: You can enter fractions as '1/7', or '3/11' for example.)
I don't see a combobox in LibreCad, only the distance input.
I'm wondering how exactly this feature works in LibreCad.

If I snap to the endpoint of a line then activate 'snap distance' and input 50,
then it will snap to a point 50 units from the endpoint on the line segment.
However, it will also snap to a point that is 50 units from the other endpoint.
I don't really understand this behavior.
It becomes troublesome when the two points are close to one another
(and the midpoint of the line segement).

Are there other ways to use this feature?

You can see this link: http://wiki.librecad.org/index.php/Snapping .
For achieving middle point functionality you can use "Snap Middle" function & set the number of middle points to 1.

For achieving fraction functionality, you can use "Snap Middle" function & set the number of middle points to one less than the denominator of the fraction & count the numerator times points from the starting point.
Eg. you want to mark a point at 1/4 AB distance from A, then set number of points as 3 & count 1 points away from A, i.e by moving mouse from A to B.
This is little bit inconvenient, but will serve the purpose.

Percentage: Convert percentage into fraction then follow as above.

It's great that you transformed from a question asker to a wiki writer.
How did you achieved that?

- use search engines
- use ctrl+f
- experiment
- consider alternatives
- ask questions

The wiki had obvious areas for improvement;
and I had experience from contributing to wikipedia.

Wiki markup is what we use to write articles:

People can also help by writing offline embedded documentation (html/css).
