Import Schematic change on PCB

Hello,

I'm working on a PCB that must be updated from the schematic, I didn't make the first version of this board and I had to create a Symbol library from the existing board, some of the components are new, so I had to make them, but when I try to import the new changes into the layout, it removes all the components and I have to re-place them, this creates a ton of extra work. Is there a way to import the schematic changes without having to start from scratch on the placement.

Attached is a plot of the settings I'm using on the schematic.

Thanks in advance

There are several things you can do that come to mind.

1) Symbols are different. Try taking the original board and doing a symbol update and saving the new board. Then import the netlist into the board. Keep the options set as you have where no ripup and don' place changed symbols.

2) Another thing to try is to export the placement prior to updating the netlist. Then once the new netlist is imported, you can quickly replace the components by using the Import Placement feature.

If neither of these works then it sounds like some *major* changes have taken place and there is no chance of keeping the design intact.
