# 3DDWFPREC System Variable [GstarCAD 2021](Help%20System/GSTARCAD/2021/Index.md) → [System Variables](Help%20System/GSTARCAD/2021/System%20Variables/(System%20Variables).md) → [3D](Help%20System/GSTARCAD/2021/System%20Variables/3D/(3D).md) ## Function Description: The 3DDWFPREC system variable is used to control the publishing precision of 3D DWF of 3D DWFx. | | | | --- | --- | | Type | Integer | | Saved in | Drawing | | Initial value | 2 | | Range | 1 \~ 6 | ## System Variable Value: | | | | --- | --- | | 3DDWFPREC Value | Precision | | 1 | 1 | | 2 | 0.5 | | 3 | 0.2 | | 4 | 0.1 | | 5 | 0.01 | | 6 | 0.001 | **Note:** Users could create multiple pages of DWF or DWFx in large size when setting the 3DDWFPREC system variable to be 5 or 6\. The higher valuel of 3DDWFPREC system variable, the finer precision. --- ## Other versions with matching text [GstarCAD 2016](../../../2016/System%20Variables/3D/3DDWFPREC%20System%20Variable.md) · [GstarCAD 2017](Help%20System/GSTARCAD/2017/System%20Variables/3D/3DDWFPREC%20System%20Variable.md) · [GstarCAD 2018](Help%20System/GSTARCAD/2018/System%20Variables/3D/3DDWFPREC%20System%20Variable.md) · [GstarCAD 2019](Help%20System/GSTARCAD/2019/System%20Variables/3D/3DDWFPREC%20System%20Variable.md) · [GstarCAD 2020](Help%20System/GSTARCAD/2020/System%20Variables/3D/3DDWFPREC%20System%20Variable.md)
