You can also adjust specific parameters such as the size and position of the text. ![](//qhstatic-sg-s3.coohom.com/image/png/1751427694485/A8CEBABD0663ECBAEEE7516DF7A7D2B5.png) ![](//qhstatic-sg-s3.coohom.com/yuntai/image/gif/1751431892258/90EF1E99951D26DFD304CA9B0F7A42F2.gif) Modeling Function ----------------- 1. Click on the**Line** or **Arc** tool in the top toolbar to draw the shape you want. * The drawn pattern must be in a closed state, so that it will become a surface after drawing. ![](//qhstatic-sg-s3.coohom.com/image/png/1770185305561/A8CEBABD0663ECBAEEE7516DF7A7D2B5.png) 2. Then you can select this surface and click on **Grouping** in the floating window. After grouping, you can **Move** , **Rotate**and edit more easily. ![](//qhstatic-sg-s3.coohom.com/yuntai/image/png/1770187005004/2D37C2734C50A6837B78ACB4959B66FF.png) 3.
