not very good at explaining in english so please bear with me.

if something says it as pcd of 150mm does it mean cirlce is 150mm diameter and if i drew it with compass the centre of bolt hole would be on the pencil line?

thank you

Yes again - just enter Pitch Circle Diameter into Google and you will get lots of diagrams!
