Alisp-Zoom-Save.LSP: Routine automatically opens any number of DWG, DXF files and zooms them to 80% of extents.

Jim McSwain of Toone, Tennessee, asked for a program to convert some old drawing and DXF files to a format that has an 80% zoom and a thumbnail preview. Many of his old drawings are standard parts that have been saved under old versions of AutoCAD, and he cannot see a thumbnail preview because the zooming was set poorly or there is no preview at all.

The AutoLISP Solution is ZOOM-SAVE.LSP and ZOOM-SAVE.DCL, which opens any number of selected DWG or DXF files and automatically zooms them to 80% of the extents of the drawing before saving with a preview.

Get the Code!
Download the ZOOM-SAVE.LSP and ZOOM-SAVE.DCL files from Cadalyst's Get the Code! library (May 2008) and save them in AutoCAD's Support directory. Use the Appload facility by selecting Tools / Load Application, then use the browser to select ZOOM-SAVE.LSP.

How to Use the ZOOM-SAVE.LSP Code
To start the program, enter ZS, and you will see the Zoom-Save dialog box.
You can select the file type to display using the DWG and DXF radio buttons. Select the drive and the directory to see a list of files in the right-hand half of the dialog box. To select files, use the standard Microsoft Windows selection procedures: Click on any file to select a single file; use the shift key to select a group of files; and hold down the Ctrl key and click to select arbitrary files.

Program works the first time then crashes the system. Tweaks with system variables and does not reset them. Great concept but needs work.
