Save As: Packed IDRZ File Format
If you want to publish ISO files, you can save them in IsoDraw Files (packed) (*.idrz) (IDRZ) format. IDRZ files can be viewed and manipulated in Arbortext IsoView the same as IDR and ISO files. IDRZ files require less storage space than ISO files—especially 3D ISO files.
* 
Do not use IDRZ as an archive format for IDR or ISO files. Arbortext IsoDraw does not save all the data in an IDR or ISO file when you save it as an IDRZ file. For example, thumbnail previews are not saved in IDRZ and the amount of 3D data retained in IDRZ is much less than ISO.
To save an IDR, ISO, or CGM (2D only) file in IDRZ format:
1. On the File menu, click Save as. The Save as dialog box opens.
2. If you want to rename the file, in the File name box, type a new name for the file. If the file was previously saved with a different name or format, that version will remain unchanged.
3. In the Save as type list, click IsoDraw Files (packed) (*.idrz).
* 
If you have unsaved changes in your file, you must save it in native IDR, ISO, or CGM (2D only) format before the IDRZ format will appear on the Save as type list.
4. Click Save to save a reduced-size version of the IDR, ISO, or CGM file in the selected IDRZ format.
