It will probably be a total rework of the clearance values which is expetected to take some time. As is now it is done per object type plan is:
  1. Assign each object on copper layers to a net.
  2. For each net.
  3. For each clearance value to other net.
  4. Grow objects with clearance value or as you name it apply bloat.
  5. Check clearance.

It is sort of therefore i factored out the different loop, in particular variables where reused although it is not clear if old values where used. I will work with clearance and do not care about the others for now.

Do you happen to know how netlist dialog box find which objects belong to net then a net is highlighted?
