Virus blocker

Hi! which virus blocker is reliable if I want to download something onto my computer before uploading revit component files

secondly how do i work in imperial in Revit? i am doing class 5 now is it introduced later or do I need to change something? thank you!

I use Mcafee

You would work with the default template. If you select browse it is under the ‘English-Imperial’
folder

thank you

how come in class 5 you set some widths of the cabinets to 60 and others to 63? where does it say to do this? and how do I know for the future? secondly is it normal the my laptop says toe heigh and depth rather then plinth? Thank you!
