urgent!請問怎樣方法可以開到pat檔?

PAT檔有三個可能性:
第一個是 Pattern File
Bitmap image used as a pattern that can be imported into multiple graphics programs; typically a square file that may be 8x8 pixels to 256x256 pixels in size; repeats to fill an area with the pattern; often used for creating a textured background
可以嘗試用 Adobe Photoshop, ACD Systems Canvas, Corel Paint shop Pro 或 CorelDRAW 來開
第二個可能性是 3D Path File
Three-dimensional model, similar to the .3DA format, but uses rectangular meshes (patches) instead of single vertices to represent 3D shapes
可以嘗試用 Autodesk AutoCAD, 或 AeroHydro SurfaceWorks 來開
第三個可能性是 Gravis UltraSound GF1 Path File
不過這是 Audio 檔, 相信應該不是你所要的
