Autodesk keeps changing their free viewers about every year. The last one is Design Review. Quite nice actually. Should work in this case.

Best is to have AutoCAD or at least access to it. This way you can sort out the border and clean up strerss ISO if needed.

I normally take customer's border as is and set it up for ISOGEN/CAESAR II. Some of the text I enter directly onto the drawing (same for all stress ISO). Changing text is positioned using co-ordinates and setups in ISOGEN. To get correct co-ordinates use LIST command or look at the free software from my site www.jat.co.za. Software is for Cadworx/ISOGEN.

Set up a style for a job and or customer. Save the style with your project.

Read the "hidden" documents that come with CAESAR II installation.
