Extension point

Description

• The extension point is a socket for calling the process implemented in the extension.

• The extension points are as follows.

  • Ribbon (menu) extension point
  • Command extension points (features that can be called from ribbon extension points and extensions)
  • Event extension point

• The extension point definition is described in the manifest for each extension.

Ribbon

• You can add a new ribbon tab.
• You can add groups within any ribbon tab.
• You can call a command by adding a button inside any ribbon tab.

command

• You can define commands in extension points and call the processes implemented in the extension according to those commands. The process called in response to a command is called a command handler.
• The command can be called from the extension point of the ribbon or the process implemented in the extension.

Event

• You can receive specific behaviors inside Next Design such as model addition operation and file save operation in Next Design as events.
• You can call the process implemented in the extension according to the received event. The process called in response to an event is called an event handler.
• You can specify the occurrence condition for each event, and you can receive only the events that the extension needs to process. This is called an event filter.
• By properly using the event filter, it is possible to avoid unnecessary event handlers being called for unnecessary events and resulting in poor response.
