Hello Members,

First time poster so am somewhat unsure of myself.

I am new to C3D 2020 and have researched to death to try and locate information of Sites, Grading Groups and

Surfaces. Have done the internet, my C3d fundamentals book, You-tube and anything else I could find on the subject

matter. I have found how to do the task of grading, develop a surface, establish a grading group but I cannot find

where there is a good guide to best management of these features and in particular when you should establish new surfaces or

grading groups in a single site (I am comfortable with understanding Sites). Sorry, perhaps I am overthinking this

but if I know when and why you should establish new grading groups and surfaces within a single Site this perhaps will remove my apprehension

factor and allow for informed decisions and perhaps avoid difficulties further down the C3D model track.

Please, any thoughts gratefully received as to where I might find the information I seek.

Regards,

Bob
