Revit in Feet

Revit is programmed in Feet, even though you have installed a Metric version of Revit. In general you will never really notice, but there are some subtle instances where it becomes obvious one is when you are exporting a model for rendering in 3DS MAX, but there are some other some of the Addins.....

When you are using some of the Addin’s that have been developed in America, because they work in Imperial the units are hard coded into the API. The result is that when we are using them in the southern hemisphere (metric) you get some crazy results and it isn’t enough to just change the units in our project/family.

To get the Addin’s to work properly, a simple conversion parameter formula is required, to get the units set correctly, this can be built into Component Families.

A couple of the Addin’s that require this conversion formula are the ‘DP Randomiser’ and the ‘Set Parameter Values from Image Data’

The example below is for setting a height, but this can be adapted for other parameters.

Because the Addin’s are imperial and set in feet, we need to create a parameter that divides the height but 304.8

1 foot = 304.8 millimetres

The ‘Actual Height’ parameter controls the family and the ‘Height’ parameter is controlled by the Addin.

Scheduling Available Fields

When you are creating schedules in your project, not all the fields will be available by default. If the field you are after isn’t in the default list you can select additional available fields from the additional options in the bottom left hand corner of the Dialogue box.

In the example below, I am creating a door schedule and I am trying to get some Room based fields to show, they can be accessed from the ‘Select available fields from:’.

Snap Close

When you are drawing an outline in your project or family a handy little keyboard shortcut is ‘SZ’ this is the Snap Close command. This moves your mouse from the last point selected to the start point, thus closing the loop.

This works with any element that is created by selecting points, like walls and sketch outlines.

When you get to the second last point, type ‘SZ’, this will move your mouse cursor to the start point of the sketch and then pick with your left mouse button, (ensure you pick with the mouse or the element won’t be closed).
