# SMOOTHMESHCONVERT System Variable [GstarCAD 2021](Help%20System/GSTARCAD/2021/Index.md) → [System Variables](Help%20System/GSTARCAD/2021/System%20Variables/(System%20Variables).md) → [S](Help%20System/GSTARCAD/2021/System%20Variables/S/(S).md) **Function Description:** The SMOOTHMESHCONVERT system variable is used to set whether to smooth or facet mesh objects that converted to 3D solids or surfaces, as well whether to merge their faces. | | | | --- | --- | | Type | Bitcode | | Saved in | User-settings | | Initial value | 0 | | Range | 0,1,2,3 | **System Variable Value:** **0:** create smooth models. Optimize or merge coplanar faces. **1:**create smooth models. The original mesh faces will be kept in objects after converting. **2:**create models whose faces are smoothed. Optimize or merge coplanar faces. **3:**create models whose faces are smoothed. The original mesh faces will be kept in objects after converting. --- ## Other versions with matching text [GstarCAD 2016](../../../2016/System%20Variables/S/SMOOTHMESHCONVERT%20System%20Variable--4b8fc803ac1e.md) · [GstarCAD 2017](Help%20System/GSTARCAD/2017/System%20Variables/S/SMOOTHMESHCONVERT%20System%20Variable--4b8fc803ac1e.md) · [GstarCAD 2018](../../../2018/System%20Variables/S/SMOOTHMESHCONVERT%20System%20Variable--4b8fc803ac1e.md) · [GstarCAD 2019](Help%20System/GSTARCAD/2019/System%20Variables/S/SMOOTHMESHCONVERT%20System%20Variable--4b8fc803ac1e.md) · [GstarCAD 2020](../../../2020/System%20Variables/S/SMOOTHMESHCONVERT%20System%20Variable--4b8fc803ac1e.md) · [GstarCAD 2022](Help%20System/GSTARCAD/2022/System%20Variables/S/SMOOTHMESHCONVERT%20System%20Variable--4b8fc803ac1e.md)
