I want to go back and remove all the copper traces in ultiboard

[HBNI]

I am new to ultiboard.  i created a circuit in multisim 14.0 and transferred it to ultiboard 14.0. then I set up a 4 layer board and created copper traces with autoroute tool. My one surface mount component did not get connected as far as I can tell. I saved the file. now when I open it. I want to go back and remove all the copper traces.  then I wan to change the number of layers and ty again.   Can this be done?

Hi HBNI

Let me see if understand, you want to re-do all your traces and change your layers?

Depending on how much work have you done I think that reimporting your circuit from Multisim can be faster.

You can also manage your nets from the Net List editor, you can find this editor in Tools>>Netlist editor.

thanks,

I will re-import from multisim.
