The Weld Tool plugin created by Rick Wilson with Smustard.com is a simple and efficient tool to turn separate line segments into a continuous poly-line. I found that this tool comes in handy when in use with other plugins such as the Extrude Edges by Face(s) plugin when groups or components will not work.
To get the most out of this plugin, I suggest to create a shortcut so you do not need to go into the tools menu to get to it. Other than that there are really no downfalls to this plugin other than it would be nice to have a button that can be placed on a toolbar and when you right click lines. It is very simple and effective when needed.
Overall, the Weld Tool plugin created by Rick Wilson with Smustard.com is a great plugin and does come in handy. At the time of this review this plugin is free and is available at Smustard.com. I give this plugin 4 out 5 stars!
