# REBUILD2DDEGREE System Variable [GstarCAD 2021](Help%20System/GSTARCAD/2021/Index.md) → [System Variables](Help%20System/GSTARCAD/2021/System%20Variables/(System%20Variables).md) → [R](Help%20System/GSTARCAD/2021/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 could rebuild more complex curves with higher degrees, but computations are required. --- ## Other versions with matching text [GstarCAD 2016](../../../2016/System%20Variables/R/REBUILD2DDEGREE%20System%20Variable.md) · [GstarCAD 2017](Help%20System/GSTARCAD/2017/System%20Variables/R/REBUILD2DDEGREE%20System%20Variable.md) · [GstarCAD 2018](Help%20System/GSTARCAD/2018/System%20Variables/R/REBUILD2DDEGREE%20System%20Variable.md) · [GstarCAD 2019](Help%20System/GSTARCAD/2019/System%20Variables/R/REBUILD2DDEGREE%20System%20Variable.md) · [GstarCAD 2020](Help%20System/GSTARCAD/2020/System%20Variables/R/REBUILD2DDEGREE%20System%20Variable.md)
