The "best method" really does differ from project-to-project, the amount of work that has been done, and what your end goal is.
In an ideal scenario, we pick the coordinates and rotation at the start before doing too much work, but understandably, sometimes it is either forgotten, or things change.
The results may vary as hosted objects sometimes lose their association, but you could try the following:
Use the "Relocate Project" tool to move the model.
- This is found in the Manage tab. More info here: https://autode.sk/3gF5GMv
- This will move the model much better than the "move" tool.
- Just be aware that the relocate option does move the project in relation to the Project Base Point & Survey Point but not for the Internal Origin Point, so the topo points may not always read 100% accurately.
For rotation, that gets a bit tricky, but if you've done a lot of work, probably best to play with Project North. At least this way you have technically rotated your model, but in a less intrusive manner.
- More info here: https://autode.sk/2ZRI69n
- If you need it rotated for True North, then you can do that too, but it may disassociate families (I've had that before and it's not fun...) You can set the True North in that same area as Project North or through the Project Base Point.
- If it's a linked file then you can rotate it with the "rotate tool" and snap to the lines in the host model to match rotation.
If you have to move the project up or down, you can use the "Relocate Project" tool as well. Just note that your levels may change values, so change it to "Shared Coordinates" instead of "Project Coordinates".
- If you move your Project Base Point to another location along with elevation changes, this will read FFL as 000, but this can be changed depending on office workflow.
If it is a linked file that needs to be relocated/rotated, then you should opt to work with Shared Coordinates.
May even be worth moving the topo itself?
- Depending on the extent of the project, it may be easier to just move the topo depending on how much work has been done.
- If it's just for aesthetics, this may be easier.
- If it's where you are acquiring your coordinates from, this won't work.
Relocate and Shared Coordinates are the least intrusive tools from personal experience.
