## Properties

### `Optional` after

• **after**? : *string | string[]*

*Inherited from [IDesignEditorCommandDefinition](idesigneditorcommanddefinition.md).[after](idesigneditorcommanddefinition.md#optional-after)*

The next commands to be executed after this command completes.

___

### `Optional` autoCompile

• **autoCompile**? : *boolean*

*Inherited from [IDesignEditorCommandDefinition](idesigneditorcommanddefinition.md).[autoCompile](idesigneditorcommanddefinition.md#optional-autocompile)*

*Inherited from [IDesignEditorCommandDefinition](idesigneditorcommanddefinition.md).[executeOnce](idesigneditorcommanddefinition.md#optional-executeonce)*

If `true`, this command will be executed only once.
You can use it for `initial` command.
For example, we need to change surface depending on the option value.
We write for `initial` and for `updateSurfaces` the same productDefinition with $['option]._
And set `executeOnce = true` for `initial`. And initial will be executed only once.

___

Current command will be executed in a next update only after all commands executed in this param.
The same example from `executeOnce` param.
We need to execute `updateSurface` on all next updates, exclude the first one.
And we set `executeOnlyAfter = ['initial']` for `updateSurface` command.
