How to create pattern fills in cad (how to create patterns in downloaded .DWG files)

CAD, the first thing you need to create their own generation of customized fill pattern library, this to use a text editor on the acad.pat library file to write. So the average person can only go to the Internet to download someone else to write a good library, can not create their own. After the library, the custom fill pattern file copied to the CAD installation directory under the Support folder, such as: C: \Program Files\AutoCAD 2006\Support and then open the CAD, enter the fill command "H", select Custom Fill. In Tianzheng, it is much simpler. First of all, they need to fill a pattern unit, select "Gallery Patterns" - "pattern management" - - "New inline pattern"-"Input a new pattern name"- -Select "to create a pattern of units" - "enter the horizontal repeat spacing" (you can enter the distance, you can also use the mouse to point to the two end points) - - "Enter the vertical repeat spacing" - that is, save successfully. Fill in the future in the system with the "other predefined" can be found in the fill.
