Any body have eperience on how to draw busbar in 2D schematic and 3D model?
there are a couple ways to do it. a couple questions first:
Answer for no. 1&2 are YES.
Answer no. 3 : I wantto represent the busbar in 2D as single line.
I am answer how to draw in 3D ?
For the 2D representation:
Create a symbol that consists of one line segment, as you wish it to appear. Ideally, the length of the line corresponds to the grid spacing you are using for your diagrams.
The symbol should have one circuit that is a "hyper-passing" type, and one connection point.
Next, insert one of these symbols in your drawing and give it the appropriate mark.
When that is done, select the symbol and copy it (Ctrl+C). Now, for each additional segment of bus bar that you want to represent on that sheet or any other, when you paste, use (Ctrl+Shift+V). In the dialog that follows, indicate that you wish to keep the same function/location/mark.
This is a quick way to create many symbols associated to the same object (your bus bar component).
If you connect an equipotential then to any of those connection points, the equipotential will be passed to the others in the schematic.
For the manufacturer part definition, continue reading about the 3D implementation.
This part requires a little more thinking. How is your bus bar going to connect to other devices? Will it connect multiple components with mechanical fasteners? Will wires terminate to it directly with welds or solder joints? Do wires terminate to it via ring terminals?
The purpose for asking these questions is to determine whether your 3D model has any requirements for adding connection points. I can say that the only time you would need to add connection points directly to the bus bar is in the event that you intended to terminate wires to it directly via solder joints or welds. The connection points serve as an attachment point and vector for routed wires.
If the bus bar is the sole conductor between two points, and attaches with mechanical fasteners then there is no need for connection points in the 3D model. When you draw the bus bar in the schematic, If i remember, two overlapping connection points will propagate an equipotential, even if no wire is drawn. I have done this to represent many circuit breakers directly attached to a bus bar.
The last case is if you are terminating wires to the bus bar using terminal lugs. In this case, you don't want to add connection points to the bus bar itself, but rather you will add a single connection point to the terminal lug model which mates to the bus bar in the assembly.
Ultimately, this relates back to how you structure your manufacturer part that you assign to your bus bar in the 2D schematic. If components terminate directly to the bus bar, then the bus bar manufacturer part will need to be defined with the appropriate number of circuits. If the wires/components terminate to the bus bar using a lug or other terminal, then define the manufacturer part with no circuits. Instead, define the terminal with a circuit and add it to the bus bar component as either a base or auxiliary component as needed in order to populate the component with circuits.
Keep in mind that it is not necessary to associate the 3D part to the 2D manufacturer part in SolidWorks Electrical. When you insert the components in your 3D assembly, it is possible to associate your mechanical part to the 2D component manually. I would advise doing this if the design of your bus bar is subject to change. Otherwise you can go ahead and make the association.
Component and symbol associations in 2D alone is a broad subject, and 3D definitely adds some complexity, so if you need clarification on anything I've discussed here, please don't hesitate to ask and I'll do my best to give you more guidance.
I will try your suggestion first then answer your follow up question later....
Many thank for answer.
Do you have picture for explain this suggestion?
Hello Michael, your answers on this forum are great. My project involves a turret board layout for an amp where restores and caps etc are soldered between two posts on opposed sides of the board. Some of these turret posts are connected together with bus bars to make connections for the circuit. A bus bar is generally used to connect common earth grounds as well. Some wires are soldered under the board to get circuit connections for widely separated components where a bus bar is not practical, i.e. the components are not side by side. Finally some wires then connect to the terminal posts for connections to potentiometers and valve/tube sockets etc.
I am wondering how best to set this up. This thread points to some hints but I need some clarification on how to proceed especially wrt how I set up the 2D symbol. For e.g. does each turret lug have a connection point? My turret board will have a fixed number of terminals in two rows opposite each other. How do I set this up so that it is possible to drop a resistor between two opposite terminal and get a connection, i.e. a soldered joint. If this is possible can I then also atch a soldered wire to it?
Re the bus bars do I need the special hyper passing type connections in this type of scenario?
Here are a couple of pics re the layout.
