[Kicad-developers] Initial Placement Idea to kick around


As I was placing a new board in PCB it occurred to me that there is a better
way to do this.What If the initial placement in PCBnew is based on the location of the components on the schematicin eeschema instead of stacked all on top of each other?Parts close to each other in the schematic tend to be close to each other on the PCB - so this seemsit would be a time saver. (Particularly on SMD work the placement tends to echo the schematiclayout ).I've used the auto-place, but not with very helpful results. I'm wondering if the auto-place mightwork better with this initial placement idea? Seems like it would be pretty easy to implement -just pulling the placement from eeschema - perhaps multiplying the coordinates by some constant. Ifnothing else it helps one pick up one part from many.If you wanted to make it a bit more complicated, one could support multiple sheets by adding an x-yoffset for each sheet.

Sounds like the foundation of a workable concept.
