Equivalent to DevSrf

Hi, I have just started using Rhino 6. Been using Rhino 5 for a few years now.

I am just wondering if there is an equivalent command in Rhino 6 to DevSrf in Rhino 5.
And if so, is there any learning material to go with it?

Thank

Sean

There’s DevLoft.

As for learning material, does the help file help?
