How to check via is closed by solder mask or not by using Allegre free physical Viewer

HAIO

Dear Team,

I am reviewing a layout using allegro-free physical viewer.

I told the layout person to close the via using a solder mask.

How I would check whether it is done or not using the allegro free viewer.

Below is the pic of two vias my board.

Regards

HARI

    In the visibility panel select either the top or bottom artwork film definitions to only view the soldermask artwork layers.

    Alternatively you could enable the appropriate soldermask layers in the color dialog window. 

    One thing to keep in mind is that the soldermask layers typically show you an inverse of what you are going to get. So if you enable the soldermask artwork and see a shape on the via, that means the via copper will be exposed. If you don't see a shape on the via, then it will be covered in mask.
