If you try to edit a path that consists of many closely spaced target points (which tends to happen when using Manual Drive) you can end up with an undriveable path. Under these circumstances you may need to delete some target points. Autodesk Vehicle Tracking may offer to perform this operation on the section of path from the point you dragged to the end. The Undriveable Path dialog is displayed at this point. Select Yes to allow Vehicle Tracking to remove points automatically or No if you want to edit the path manually.
- If you select Yes, Vehicle Tracking removes closely spaced points on the section of path from the selected point to the end of the path. This may not always result in a driveable path, because it only removes points and does not optimize those remaining, but is nevertheless the recommended option. Use Undo to restore the path if you don’t like the changes that Vehicle Tracking makes.
- If you select No, the path is not altered (apart from storing the data slightly differently, as explained below).
Attention: Manual Drive path data is converted to AutoDrive target points as soon as you try to edit it. For this reason, changing a model value on a non-errored path can result in a path error, but changing it back will not necessarily produce the original non-errored path. To get back the original path, you should use Undo.
