A question I was asked recently was how to stop Revit automatically committing changes to parameters made to elements as the cursor slides off the property’s palette and onto the screen. This can be annoying if changes are being made whilst discussing with a colleague or using an on-screen keyboard. With typical optical mice, the cursor can have a habit of wandering, especially on a shiny clean desk! Previously Revit used to require the application of pressing the Apply button on the dialogue.
In recent years, an automatic apply behaviour was introduced, but this can be disabled by editing the Revit.ini file. The Revit.ini file is usually located in the users roaming profile for example:
C:\Users\USERNAME\Appdata\Roaming\Autodesk\Revit\Autodesk Revit 20XX
I usually recommend taking a backup copy of the INI file just in case anything goes awry. Once located and backed up, open in an application like Notepad and navigate to the user interface section, set the property DisableMppAutoApply to be equal to 1. It’s possible that this entry needs to be entered manually.
Once complete that section of the Ini file should look like the example below.
[UserInterface]
DisableMppAutoApply=1
Start Revit and any changes that need to be committed can now be confirmed by pressing Apply on the Properties palette. Revit how it used to be several years ago!
