Wrong axis obtained of vertices from two or three objects

[micheus]

During the tests with the plugin Absolute Command - Rotate, PuzzledPaul had reported me that was getting an unwanted result when the axis selected was obtained from three vertices in two different objects. It was noticed that its a "global" problem since the routine is the same used for many operations that ask for a "customized" axis.

Here a example which I used the Rotate command to rotate the box 60° around the axis defined by three vertex:


The file for replacement is this: wings_vec.beam (it should be placed in some place like that: C:\Program Files (x86)\wings3d_1.5.3\lib\wings-1.5.3\ebin)
