Combines given T-spline surfaces into a single one. Surfaces can be disjoint. If at least one surface is in box mode, the output surface will be in box mode as well. Note: All input surfaces must have the same version in order to be combined successfully. For this reason, one or more surfaces may be cloned internally and their versions either upgraded or downgraded to match the version currently used in Dynamo. The resulting surface may therefore have subtle differences from what might be the expected result. The input surfaces themselves will remain unchanged.
