A typical electrical distribution is where certain lighting loads are connected to the same junction box. To speed up this process, a tool called "Horizontal, to junction box" has been included in the "Distribution" block of the toolbar.
The tool works by selecting the loads that are supplied from the same junction box, then click on the right mouse button and then select the junction box itself. The program will generate the connection distribution (star shaped), both horizontal and vertical, between each load and the junction box.
