UnitMigration

Migrate all unit settings from a source RVT to a folder full of target RVT models.

Change Project Units between Imperial and Metric With One Button

This add-in has been created and published in response to the Revit Idea Station request by Kasper Miller to change project units between imperial and metric with one button.

Kasper explains:

This should be easy implement and will save a lot of time.

Currently, the process of converting an Imperial Revit family, project or template to metric or vice versa is very cumbersome.

Particularly if you have do so with several items, which is a task all of us are confronted with very frequently.

One has to toggle through all the unit options, which might consist of 7 categories. Within each of these, we usually have to change at least two options.

That makes 14 clicks and changes for each instance.

What often happens then, is that users just change the Length category, leaving the family mixed, part imperial, part metric, for instance like this:

Solution

The solution is straight-forward: all unit settings seen by a user in a document in ProjectUnits are stored in a container class DisplayUnit.

These settings can be read from one document through its DisplayUnitSystem and set to another with the SetUnits method.

The add-in take the source data from a source document, stores it, and sets it to all target documents.

One could obviously alter this to read data from a text file or something more fancy – but why bother when you can use a Revit template?

Want to convert to metric? Select the metric template of your choice and paste it where you want.

Want to convert to imperial? Same thing.

Imperial decimal to imperial fractional? Just like before.

The add-in requires a source file (like a template) from which to read the units; then, it will write those units to all Revit files inside a selected folder.
