Mask tool missing

Hello @Tara_O_Reilly_RGD, Thank you for getting in touch with us.

Are you exploring UI3? If so, we’re thrilled to hear that!
If you have an object selected, you may notice the “Use as mask” icon in the properties panel on the right side. Depending on the available actions, you might find “Use as mask” in the “More” menu.

Please remember you can always refer back to this article to check where a feature has moved to.

I hope this information is helpful for you!
Thank you once again for reaching out.
