layer i do not see

[MvdHeuvel]

Hi,

I was drawing a print in ultiboard but somrthing went wrong and i lost 2 inner layers. I made 2 inner layers again an started to draw again but then a error occurs. Somehow i can not see the 2 layers i drawed earlier but they do exist because i get DRC connection errors. This means i have via's connecting to the inner layers i do not see. How can i bring these layers back? or how do i delete these layers?

Tnx,

Dear MvdHeuvel,

thank you for your post on our webforum. Are the layers not visible in the design toolbox? How many layer pairs are visible in the PCB properties (under options), you can find the layer pairs under the copper layer tab. By changing the layer pairs you can add or remove the inner layers.

Best regards,
