A DWT file is an AutoCAD drawing template file that is used as a starter for creating drawings that can be saved as DWG files. Such template files provide initial settings such as unit types, the precision required, title blocks, layer names, line types, and other similar information for lateral conversion to proper drawing files. Both AutoCAD and CoreCAD can be used to read the template files and utilize them further.
Files with .POTX extension represent Microsoft PowerPoint template presentations that are created with Microsoft PowerPoint 2007 and above. This format was created to replace the POT file format that is based on the binary file format and is supported with PowerPoint 97-2003. The files generated can be used to create presentations that have same layout and other settings required to be applied to new files. These settings can include styles, backgrounds, colour palette, fonts and defaults. Such files are generated in order to create ready-to-use template files for official use.
You can also convert DWT into many other file formats. Please see the complete list below.
