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. --- [Original help](https://www.gstarcad.net/help/GstarCAD_2026_en-US/detail/systemVariables_Sgsv/SMOOTHMESHCONVERT.html) · © Gstarsoft Co., Ltd.
