Hello-world

Download and prepare

As a simple extension sample, you can download the extension that displays a message with a button on the ribbon at the following link:

Download link: hello-world.zip

Unzip the downloaded zip file and copy the hello-world folder containing the manifest.json file to the following folder under the extensions folder.

{user home path}\AppData\Local\DENSO CREATE\Next Design\extensions\

User home path example: C:\Users\user-name

To create this extension yourself, follow the steps below.

• Create a hello-world folder directly under the extensions folder above.
• Create an images folder in the hello-world folder and prepare About.png which will be the button image on the ribbon (32 x 32 images are recommended).
• Create manifest.json and main.cs in the hello-world folder.

manifest.json

This manifest defines one button on the ribbon and one command to execute on the button.
