| #146 MAIN - Resolved - -11.1 command does not intersect correctly | |

| Title | -11.1 command does not intersect correctly |
| Description |
The -11.1 command computes offset lines at a set distance from a known centerline. If the 1st PI and 2nd PI are separated by a 0 instead of a valid offset, then the real offset follows the 2nd point number and the tangent intersects with the line defined by the 1st and 2nd points. Same process for the last 2 points. Currently the program does not compute this because it thinks the offset is a non-existent point number.
See the example in the comments. Also see the help files and gifs at www.ipogo.net, methodology 2 for this command. |

| Resolution | The variations on this command did not conform to other commands in that the number of data elements changed depending on the 0 offset existence. In order maintain the iPOGO language without widely varying versions of one command, we have opted to replace the 0 offset variation with a new command in the next release. In the meantime, any use of a 0 offset in the -11.1 command will result in an error message of either 'invalid offset' or 'non-existent point'. |
