Need help w/ spoke length
Bought some hubs and rims from Velo Orange. I want to build a 3x (3cross) wheels using DT Swiss Comp spokes. Can someone please help me determine what spoke lengths I need? Thank you in advance for your expertise: Here are the links to the hubs and rims:

The rims I purchased are the 650b.
Thank you again for your help.

First try asking Velo Orange as they may have the numbers for you. If not, here is one instructional page and a plug-in-the-numbers app for spoke length. How to measure hub and rim dimensions (leonard.io) Edd, an easy to use spoke calculator (leonard.io) Here's another site listing some more apps to check out. 5 Best Spoke Length Calculators – BikeFAT

If you want to do it yourself this has your stuff in it already easy to calculate and what I generally use for my wheels these days:

However your wheel builder can also build it up for you and figure all of that out without all the stress.

I doubt anyone here is actually going to *tell* you the lengths, as the results are largely dependent on *your* measurements. You should at least measure your rims for their ERD, and preferably measure the hubs as well, since the posted values may be wrong. If you have a good wheel-building book, you'll find that measuring these parameters is not difficult, and you'll be more confident that things will work.
I've used Roger Musson's book for several wheels. It's a good book and not expensive. Wheelbuilding is fun!

I've used this calculator with good results.
https://www.prowheelbuilder.com/spokelengthcalculator
The numbers you need to enter are listed on the hub and rim pages.
Are you planning to build them yourself? If not, I'd let the builder determine the length because if there is an error it is on them! I have had to re-order spokes when for some reason the length just did not come out right.

Does this look right for the rear one? I added both the rim and hub from their drop down and then the 3 and 3 under spoke pattern. Is their any thing else? Offset? Thanks again.

You need to measure hub and the rim in order to calculate the optimal spoke lenght.
I've tried to explain the basics here:
Bicycle wheel building basics - chapter 5
That article contains links to articles (and videos) that explain (and show) how is what done (what to measure and how, how to calculate, prepare, lace etc.).
I would also recommend spending $12 for this book by Roger Musson:
Professional Guide to Wheel Building 7th Edition pdf

In case this hasn't been stressed enough: always always always measure the hub and rim yourself. Published values are fine to compare to but never rely on them only. I've avoided buying the wrong length spokes many times this way.
I use the Edd spoke calculator, linked somewhere above.

Definitely measure both the rim and hub yourself and confirm the listed numbers.
