One main focus of the
Revit 2013 API features
is better support for
add-in integration.
This includes the possibility for an add-in to replace an existing Revit command with its own implementation.
Note that you cannot call an existing command, just replace it entirely.
Such a command replacement is demonstrated in a very simple form by the
DisableCommand SDK sample,
which disables a command by replacing its implementation with a simple popup message.
A slightly more complex example is given by the
UIAPI SDK sample,
which implements and installs an alternative command binding for the Design Model command to start up a new family freshly created from the conceptual mass template and display its 3D view.
These are the steps to replace a built-in Revit command:
- Determine the RevitCommandId to replace by examining the journal file and searching for the name of the original command.
- Create an AddInCommandBinding for this command id.
- Provide an alternate implementation for the command binding.
List of all Revit Command Ids
To simplify the first step, Victor Chekalin aka Виктор Чекалин now presents a list of all Revit command ids,
In Victor’s own words:
I’m learning the ability to replace a Revit command with my own add-in implementation.
To replace a command, I must know CommandId of the command which I want to replace.
The help tells me I can find a CommandId in the journal file.
So the Revit SDK help doesn’t contains full list of CommandIds.
I have decided to correct this mistake and create that list.
I thought this information will be useful for you and other developers and send you the list of all command ids in both
text and
Excel
format.
Question: Wow!
How did you create this list?
Answer: It is my little secret how I’ve got it. Joke :-)
At first I thought the commands must be described somewhere.
I searched for the text ‘ID_EXPORT_IFC’ (the command name from the Dev Days Online – Revit 2013 API) in all files at the Revit Program folder.
So I found the UIFramework.dll file.
I opened this file in the text editor and saw XML data containing command descriptions.
Next steps were very easy.
I saved this part of the UIFramework.dll file to the XML file and read the XML data:
private IEnumerable<InternalCommandDef>
ReadCommandsFromFile()
{
using( var streamReader
= File.OpenText( @"C:UsersChekalinVV"
+ "DocumentsRevitRevit2013SDK"
+ "RevitUICommands.xml" ) )
{
using( var reader = XmlReader.Create(
streamReader ) )
{
while( reader.Read() )
{
if( reader.Name.Equals( "Command" ) )
{
InternalCommandDef commandDef
= new InternalCommandDef();
if( reader.MoveToAttribute( "Path" ) )
commandDef.Path = reader.Value;
if( reader.MoveToAttribute( "CommandId" ) )
commandDef.CommandId = reader.Value;
yield return commandDef;
}
}
}
}
}
Retrieve get CommandId info for each command and write it to the text file:
using( var textFile = File.CreateText(
@"C:UsersChekalinVVDocumentsRevit"
+ "Revit2013SDKRevitUICommands.txt" ) )
{
foreach( var command in commands )
{
RevitCommandId commandId = RevitCommandId
.LookupCommandId( command.CommandId );
if( commandId == null ) continue;
command.CanHaveBinding
= commandId.CanHaveBinding;
command.Id = commandId.Id;
textFile.WriteLine( "{0}t{1}t{2}t{3}",
command.CommandId,
command.Path,
command.Id,
command.CanHaveBinding );
/* It is just a joke
if( !commandId.HasBinding
&& commandId.CanHaveBinding )
{
var commandBinding =
App.ControlledApplication
.CreateAddInCommandBinding(commandId);
commandBinding.Executed += OnCommandExecute;
}
*/
}
}
}
It is not necessary to get full CommandId properties, but I wanted to retrieve the CanHaveBinding property for all commands.
As I can see only two commands cannot have binding: Undo and Redo commands.
Although I try to bind ID_APP_EXIT command (just for test because it was the first command I found in the journal files).
It binds without any errors but doesn’t work.
Very many thanks to Victor for this interesting research and the useful comprehensive list!
