| Sub-Domain²s | S² | Surface sub-domain² for each span that makes up the surface
To extract each span as a separate surface use these as the Domain(D) input on Grasshopper's Isotrim component. | Domain² |
| Sub-Domain U | uS | Domain in {u} direction of each span that makes up the surface | Domain |
| Sub-Domain V | vS | Domain in {v} direction of each span that makes up the surface | Domain |
| Amount U | uA | Amount of spans in the {u} direction that make up the surface | Integer |
| Amount V | vA | Amount of spans in the {v} direction that make up the surface | Integer |
| Lengths U | uL | Approximate length in {u} direction of each span that makes up the surface | Number |
| Lengths V | vL | Approximate length in {v} direction of each span that makes up the surface | Number |
| Degrees U | uD | Degree in {u} direction of each span that makes up the surface | Integer |
| Degrees V | vD | Degree in {v} direction of each span that makes up the surface | Integer |
| Parameters U | u | Parameter in {u} direction of each span isocurve that makes up the surface | Number |
| Parameters V | v | Parameter in {v} direction of each span isocurve that makes up the surface | Number |
| Parameters UV | uv | Surface parameter coordinates at the span ends
To get the point between each span use these as the Point(uv) input on Grasshopper's Evaluate Surface component. | Point |
