Make 3D paths creating and modifying easier and cleaner.
1.Create some preset movement for rotations (concrete site boom, tower cranes, cars driving)
2.Also for the modifying 3D paths, is there a way to adjust the position of 3D object and time (like the animation editor)
3.Only show the selected 3D paths (htoes arrows) in 3D window, not all of them, which makes the view very busy.
It is difficult to make presets that are relevant since the paths needed for each construction site and company will be different. If your company frequently uses the same equipment and paths, you can create a template SP file that contains the equipment and paths, then import that to the master SP as needed.
You can edit the position and/or time of each 3D Path keyframe in 3D Path Properties, when the resource, task, and path are all selected. In the Keyframe List tab, you can edit the time of the keyframe, or move the focus time to where you want to move the keyframe to then in the Keyframe tab, right click and choose Capture Focus time. You can edit the position for the selected keyframe, either by typing the position values in the Keyframe tab (then press Apply button when finished) or typing in the Keyframe List table, or by right clicking in the Keyframe tab and choose Edit Key to use the manipulator widget to update the position.
There already is a feature for filtering specific 3D Paths. In Navigator>Task and Path Filters, right click and choose Add Path Filter. You can filter by "Name" (e.g. search for all paths with a certain word in the name) or Path (turn paths on or off by check box)
