Re: [Kicad-developers] Routing algorithm used in PCB
At least the non-resource intensive tasks like creating schematics, symbols and foot prints etc can be pushed on to the web. Resource intensive tasks can be done by a server side code (c++ or python code which you already developed can be used at the server side). Google is able to run services like sheets, docs and other resource intensive services on the cloud. Everything will eventually move to the cloud. It's better that we start a web based as early as possible. Today even the development environment like IDEs, SDK, workspaces have moved to cloud (example https://www.codenvy.com/) On Mon, Aug 28, 2017 at 10:26 PM, Bastian Neumannn < neumann.bast...@gmail.com> wrote: > KiCad does come with a python interface. > Moving to python as native system and other web technologies are not a > good idea imho. > > Not every software is better with web and cloud stuff. > > 2017-08-28 18:04 GMT+02:00 Arun Kumar : > >> Documentation of code or the usage of Kicad?

Documentation of code or the usage of Kicad? I see that there is already documentation on the user guide. Would be happy if Kicad transitions to python or other web technologies.

Re: [Kicad-developers] wire connections
Now I realise that it's a bit complex because of the followup steps. Make the drawing area as a 2D array grid P[ ] [ ] with walkable points representing as 0 and obstacle points as 1. walkable point P[5][6] =0 obstacle point P[5] [7] = 1 1) On each part's drag stop event, make the area (bounding box of the part) occupied by the part as obstacle so that wire cannot be drawn over it. 2) Make the area from where the part moved as walkable so that other wires can pass through that area. 3) check if paths already exist with the pins of the part moved. If yes, remove that path and make the area of the path walkable. else check next pin 4) Draw the new path from the new position and mark he path as obstacle so that other wires do not overlap with this. 5) Push the new path into an array or object. 6) update the walkable and obstacles in the grid 7) iterate the above steps with other pins of the part moved.

Re: [Kicad-developers] Routing algorithm used in PCB
I don't know C++ so unable to contribute and I want to build my own FOSS app with the languages I know. I always wanted to contribute to an existing project there isn't a proper documentation about the source code. Have to go through hundreds and thousands of lines of code to understand where they have implemented a specific functionality. I browsed the folders of the source code of Kicad but unable to understand what routing techniques are used and the code associated with it. I found a folder with name algorithm but couldn't understand how they're working with the parts.

Re: [Kicad-developers] wire connections
Yes, I'm referring to the schematic wires. Through the G hotkey has the functionality, the wires are not orthogonal bend at 90 degrees) after drag/move. I don't think it would be lot of logic to add. Because we can use any existing routing library such as A* search algorithm. 1) Call the routing library immediately after the drag stop event. 2) Pass the part dragged to the routing library and the connections associated with it. 3) The A* search library re-draws the wires.

Hi Team, The wire connections doesn't move or sustain when the parts are moved around. Is there any work going on to address this. Almost in all commercial softwares the wires connections adjust as per the movement of the parts.

I'm working on a Web based open source schematic editor. So want to borrow
some techniques from kicad.
