# 3DDWFPREC [GstarCAD 2022](Help%20System/GSTARCAD/2022/Index.md) → [System Variables](Help%20System/GSTARCAD/2022/System%20Variables/(System%20Variables).md) → [3D](Help%20System/GSTARCAD/2022/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:** | | | | --- | --- | | Value | Precision | | 1 | 1 | | 2 | 0.5 | | 3 | 0.2 | | 4 | 0.1 | | 5 | 0.01 | | 6 | 0.001 | **Note:** Users can 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.
