# REBUILD2DDEGREE System Variable [GstarCAD 2022](Help%20System/GSTARCAD/2022/Index.md) → [System Variables](Help%20System/GSTARCAD/2022/System%20Variables/(System%20Variables).md) → [R](Help%20System/GSTARCAD/2022/System%20Variables/R/(R).md) **Function Description:** The REBUILD2DDEGREE system variable is used to set the global degree when rebuilding a spline. | | | | --- | --- | | Type | Integer | | Saved in | Registry | | Initial value | 3 | | Range | 1 \~ 11 | If the degree is 1, it rebuilds a straight line; if the degree is 2, it rebuilds a curve with one bend. A Bezier curve has a degree of 3\. It can rebuild more complex curves with higher degrees, but computations are required.
