Project Units Matter - Specify Coordinates at Point

When we use the Specify Coordinates at Point (SPaC) it is possible that the units in use will affect your results. For example, this project is using Feet and Fractional Inches (FaFI) but for SPaC to match the available survey info it was changed to Decimal Inches (DI) with six decimal places. After using SPaC the units were returned to FaFI.

Some time later the elevation needed to be changed thus causing us to revisit using SPaC. The following image shows the original values used for SPaC.

Leaving the Project Units assigned to FaFI resulted is this subtle change to the coordinate values.

When the units were revised to match the earlier DI settings the SPaC coordinates are not altered.

Shorter story, be careful with your unit settings when using SPaC.

Temporary Dimensions and Activate Dimensions

I've written about Temporary Dimensions and the Activate Dimension button in the past (2007-9), these are some posts that discuss them.

Temporary Dimensions don't appear when two or more elements are selected. When that happens you should see the Activate Dimensions button appear on the Options Bar.

Temporary dimensions also don't respond to families that host nested shared families. That's because these families are also regarded by Revit, under the hood, as a selection of two or more elements.
