This layout tool is based on the align and distribute tools available in Adobe Illustrator with the idea extended to 3 dimensions.

This is an update to LineXLine script. Instead of poins you can now work with edges and two or more lines. As before, this simple plugin finds an intersection point of two lines in either 2D (on the same plane that is) or 3D. If a 2D intersection is found a single point is created [...]

This simple script finds an intersection point of two lines in either 2D (on the same plane that is) or 3D. If intersection is found a single point is created at the intersection. If two lines exist in 3D and they do not intersect, two points are created defining the shortest line between the two [...]

This simple script finds an intersection point of a line and a plane in 3D. If intersection is found a single point is created at the intersection. Line is defined by two points and plane is defined by three points. None of these points are required to be a part of a polygon

This plug-in puts all selected points on a straight line. There are two separate scripts included: Line Up Points and Line Up Points EQ. The first script lines up points by projecting them on a line. The EQ script spaces the points equally on a line. The line is always defined by the first and [...]

This modeler tool is based on the align and distribute tools available in Adobe Illustrator with the idea extended to 3 dimensions.

Aligns points along a user-defined vector. This was designed in situations where you want points aligned, but not necessarily straight along any axis, like a diagonal line that needs to stay diagonal. The scripts are separated into a total of six named after the axis orientation you wish the alignment to take place and for [...]

This plugin adjusts UV chart direction. UV chart is a group of polygons connected by the points which coincide on point number and UV coordinate. It minimizes the area of a rectangle which encompasses UV chart tightly.

From the developers website, using Google Translate: Given to the selected vector, the vector is rotated to align selected. Turn_Normal is a little different.

From the developers website, using Google Translate: Selected points on the line first and second, to align the axes to secure the points after the first three groups. Align the two dimensional appearance on two axes will be fixed. (Three-dimensional space is not aligned state) Corresponds to more than one layer.
