Re: Batch/multi-export ?
One of the options for exporting the Part Studio is the export the parts as individual files.
Re: surface not splitting object when should
Reversing the order of the splits gives some insight: I believe the result of the two splits together (regardless of order) is a non-manifold body. The two touching cylinders in the image below create an edge that touches two pieces of the same body.
You could modify the geometry around that intersection slightly one to make it work.
However, overall, I think you'll have an easier time creating the object you want by working with solids, not surfaces (doing boolean intersects or subtracts rather than splits). To make a solid out of those surfaces you can use the Fill feature.

Re: How to access data written to parts with setAttribute
Hello and welcome!
The best way to get the attributes you've set is via the evaluate FeatureScript API. You can refer to to the developer portal help section titled "Feature list API" for an example of calling this API.
The FeatureScript function you provide can then:
Let us know if you have any questions!

The FeatureScript function you provide can then:
- Query for the relevant parts (possibly qEverything, possibly qAttributeQuery to filter for parts with your attribute type)
- Get the attribute as a variable via getAttributes
- Return the attribute or attributes

Working with meshes
A few months ago it was asked "Why do we need meshes?" and someone replied "To bring the world back into CAD".
OS is working really well with mesh data so here's a little example of working with mesh data & OS.
So I wanted to design a small motorcycle part hiding a seat latch. You can see the cover below located close to OS's origin and behind the meshed seat.
I have a structure scanner that fits onto an ipad. It's ok for larger objects and the accuracy is good enough to get an understanding of where things are.

I take multiple scans at different resolutions to capture geometry and definition. The trick is to line this mesh data up in OS. I'll illustrate these steps by positioning the rear tire.
Steps to line up mesh data:
-rotate mesh and align to OS's datums
-translate mesh
Tire mesh before adjustments:
It's not perfect, but it's good enough:
I also used pictures to help re-enforce where the world is inside OS. Showing build curves in OS:

Once the design was complete, I printed it out and the 1st one fit like a glove.

Improvements to Onshape - July 6th, 2017
We have an awesome update for you! This update includes major new surfacing tools, a new drawing view tool, improvements to Loft, Hole feature, and more. Let's check it out.
FILL
You can now create a surface defined by a boundary of edges or curves.
ENCLOSE
Create a solid part from an enclosed selection of surfaces or planes.
GUIDES AND END CONDITIONS IN LOFT
You can now use a combination of guides and end conditions in the Loft command. In the past, you had to choose one or the other.
SECTION VIEWS AS NAMED VIEWS
If you are in a Section view, and create a Named view, this will be saved with the Named view. Meaning when you return to your Named view, the Section view state is also restored. Great if you find yourself repeatedly creating the same Section view.
HOLE FEATURE IMPROVEMENTS
There were many improvements to Hole feature with this update. Including new standard hole sizes, and the ability to create holes in sheet metal parts.
SECTION VIEW IMPROVEMENTS
You'll find a new "Angular" section view type in Onshape Drawings. This option allows you to create section views at an angle. Also added with this update is the ability to change a view's label.
COPY/PASTE CONTEXT MENU IN ONSHAPE DRAWINGS
You can now right-click "Copy" and right-click "Paste" entities in Onshape Drawings. In this past this was limited to keyboard shortcuts.
WELD SYMBOL IMPROVEMENTS
A few important improvements to Weld symbols were added with this update. Including live updates to the Weld symbol preview, as well as support for staggered welds.
ORDERED ARRAY OF FEATURESCRIPT PARAMETERS
The foundation has been laid to allow you to make per selection changes to parameters in Onshape while creating a feature. This means you can have different settings for each selection within a dialog. Currently, you can only see this in the Fill command (where you can make "per edge" continuity choices), but we are working on more features with this capability. Below is an example of the custom "Port Feature" that has been modified to allow the user to change port size for each selection.
PERFORMANCE IMPROVEMENTS
Performance has been improved in several areas including assemblies, drawings, holes and more.
Please take a moment to try out these new features and improvements and let us know what you think!
Remember: The updates listed here are now live for all users when creating new Documents and over the next few days these features will also be available in Documents created before the date of this update.

Re: Can groups / assemblies be defined in a part studio
You can create your entire sub assembly in a part studio. And treat it as a sub assembly, and detail it as such.
But You won't get proper part counts, as each part will be unique and need it's own properties. I guess this only matters if you're using a BOM app.
Instead just insert your part studio into an assembly, then use the group mate to lock everything in position (mate your whole studio in one mate
Then replace all of the duplicate parts in the assembly with the main part. Don't forget to "Fix" one of the parts to lock it relative to the origin.
You can also insert assemblies into higher level assemblies to get your sub assembly structure.
To define an assembly FROM a part studio.. No. Part studio's live on the lowest level of a tree. Assemblies can reference studio's, but studio's cannot reference Assemblies (With the exception of In-Context which is another topic)

Re: How do you find the center of gravity?
In CAD space you would generally assume these to be the same, which they are if gravity is constant across the rigid body. If the object was large enough and rigid enough to have varying gravity, center of gravity would differ to center of mass.
Re: how do you place a point at a specific set of xyz coordinates?
What is the purpose? If it is for inputting data from elsewhere then you might want to consider writing a custom feature. Otherwise create a plane offset from x y or z then sketch on that.
