Flux doesn't have a dedicated command for forcing a complete redraw of the schematic canvas. If zooming and refreshing haven't helped, try performing a hard refresh (Shift+Reload your browser) to clear any cached view data. If that still doesn't work, it might be best to check the project object tree for the components and contact Flux support for further troubleshooting.

Before proceeding, could you clarify what you'd like to do? Do you want to clear the current project entirely and recreate the schematic from scratch with the 48 channel design, or would you prefer to simply reapply the schematic changes within this project? Please let me know how you'd like to proceed.

I can't clear a project's data directly. However, you can create a new Flux project to start fresh with your 48-channel design. Would you like instructions on how to create a new project and then reapply the schematic updates?
