Originally posted by: ltollesonYou can use the "cat" (concatenate) node to combine multiple datasets into one. There are 3 modes that can be used depending on the data. Exact means that all fields in all datasets must be the same. Union will combine all fields from all datasets even if they are different. Missing fields from any dataset will be filled with nulls. The last mode is Intersection. This mode will only keep like fields between all datasets.
The "cat" node by default only has one input into the node. You will need to create new inputs on the node for multiple datasets. Simply drag the wire from each dataset onto the node. This will create a new input.
