The dwg format cannot be directly converted into a pat file. You can open a pat file with Notepad. It is filled with cells described by numbers and letters. The definition is very complicated.You can either find the original pat file, or use the super fill function in the acad or haochen cad extension tool. You can select a block as a temporary fill.Of course, it is best to find the original pat file.
All dwg drawings received on WeChat can be opened with Haochen CAD ViewKing. You can directly click the drawing to select other applications and select Haochen CAD ViewKing when you open them. However, recently WeChat changed the received file, adding a lot of suffixes to the file name dwg. If your drawing dwg has suffixes, download the drawing first, find the drawing in the file manager, rename the drawing, and delete the back of the dwg.
