Hello, recently I watched a video which explains how to use JHS powerbar to create curved surfaces, and I've already installed the file from this site itself, 'JHS_PowerBar_2015_v2.4.rbz'

How can we install it into sketchup?

Thanks for the help,
Rita.

There are 2 easy ways to install plugins from the Sketchucation site to SketchUp:

Download the .rbz from https://sketchucation.com/pluginstore and save it to your hard drive. In SketchUp select the Window / Extension Manager menu point. At the extension manager window click "Install extension" and in the open file window you select the .rbz file of the plugin. In case you plan to install more than one plugin it is better to first install SketchUcation Tools plugin from https://sketchucation.com/resources/plugin-store-download with the above mentioned method. From this plugin you can easily auto install any plugins from the SketchUcation site.
