I’m drawing an HVAC control circuit consisting of components such as pumps and thermostats that are connected with 120 VAC, 26 VAC, transformers, relays and switches. I’m using transformers, relays and switches from schematic symbols, as well as basic shapes to represent components.
I’m really struggling with the lines. For example, I used an ellipse to represent a pump and a spst switch to represent an aquastat. If I start a line from the switch, it has square corners and the type is “net”. This line type has different properties, such as when multiple of the are joined, the joint is a dot. If I start a line from an ellipse, it has different properties, including round corners, and these lines don’t join the same way. I would like all of the lines to have the same properties, such as all square or all round corners.
I would also like to depict connections of different color lines, such as black to white, I can’t seem to draw a line without drawing both ends.
How do I draw a free standing line that I can connect each end as I draw objects, as well as join two lines together? Is there a FAQ somewhere?
