ROTATE PROJECT NORTH

In Revit there is a command to rotate Project North. Unlike Rotate True North the Rotate Project North command actually rotates everything the the model, it basically uses the Rotate command to rotate everything.

This can have severe consequences.

PROBLEMS

Often the command will not work as some items can not be rotated. These items have to be deleted before it will work.

The official list of items NOT rotated are:

• Text

• Some Floor-Based Component Families

• Decals

• Symbols

• Property Lines

• Detail Lines

• Detail Component

• Detail Groups

• Masking Region

• Repeating Detail

• Filled Region

• Revision Cloud

Elevations are not rotated so they are no longer aligned (you can not use the rotate command on elevations). All elevations will have to be recreated.

Views on sheets will be messed up and have to be reconfigured. Sometimes dimensions and tags want to delete themselves.

Linked Revit and CAD inserts may need to be rotated. CAD files placed in current view only will need to be found and rotated.

Shared Coordinates will need to be updated.

If you have already issued your model to consultants they will be very upset and may well come to your house and burn it down.

The biggest problem is you can never be sure what has happened to every element. You may not discover a major error until much later when it is too late to revert back.

On investigation some of the things to watch out for:

(Be aware there could be more)

• Site and Planting category elements hosted on TopOfSurfaces behave very badly. Sometimes you can fix them by manually rotating them back.

• Note Site and Planting category elements NOT hosted on ToS rotate OK, so you can't just select all Site category items and rotate them back.

• Any element hosted on a plane not parallel or perpendicular to plan view will either not rotate at all (and has to be deleted) or rotates badly.

• For example elements hosted slopping reference planes, sloping floors, ramps, masses etc.

• Foundations don't want to be rotated (don't know why).

• Things place in views that have been rotated behave strangely.

• Rotating a very small amount has less effect than large amounts.

You may get away with it, as long as it is done very early in the project before much stuff has been done, otherwise:

The bottom line is DON'T DO IT.
