Aiming for a seamless weld

In this article, I use the Select tool (A), the Line tool (B) and the Move tool (C). When you click a line endpoint with the Move tool, that point will be marked with a purple dot. The message “Endpoint in Component” will appear. Move the endpoint (and thus the entire component) towards the identical endpoint of the other component. When the two endpoints are close enough to each other, the components are automatically aligned. The result: a seamless weld.
