I am using the eagle cadsoft software to complete a schematic board; but i am having a hard time getting the wires to connect. I am making changes to the drawing, as a result i have drawn new parts to replace existing parts. Does anyone know what the problem is?
If you created components with pins in the symbol on a different grid setting to the default, then this problem will remain. You'll need to edit any components that you created and get the pins placed on the default grid locations.
Aside from that, there is no reason I can think of for nets to not connect to pins. As long as you follow the rule never to touch the grid in the schematic view and when creating the component symbol, then the nets will connect.
By the way, when creating the schematic, don't use 'lines' or Wire, use 'nets'. In other words, use the icon shown in the green circle below, not the one in the red circle.
