Milling Holes in PCB are not going through the Copper Layer

[osamaolabi]

Hello everyone,

When I create a milling hole in the PCB design, It does not go through the copper layer in 3D view. How can I get it to go all the way through? 

Attached are the pictures where you can see in the 3D model the copper layer has not been cut.

*Please note this is an example sketch*

Hi, @osamaolabi 

Did you drilled hole from 3D PCB and then just push to 2D for one time? 3D PCB is relied on 2D now so a round of 3D<>2D sync is needed.

I guess the milling hole is overlap with polygon, right? If my thought is wrong, Would you please share the 2D PCB you demonstrated to us?

Thanks,
