CAL to PDF Conversion

[lmckenna]

I am having trouble with the batch and sequence conversion of CAL files to PDF. The process takes 2 to 5 minutes per page (30 x 44 inch engineering drawings), and all I get out is a blank page - none of the drawing or text is present. Anyone have any thoughts? Thanks.

And do you have problem to load CAL files?

I have no problem loading, viewing or printing the drawings to a plotter. This is why it is so puzzling.

A similar issue was reported in this more recent, lengthy thread:

The solution was summarised as follows in this post:

I think the problem is effectively solved, at least until someone posts a new problem with the CAL format, by the above insights:

A PDF file created from an image that has a page dimension greater than a certain (very large) value may not display correctly in some PDF viewer software;

The problem can be overcome by increasing the DPI value of the opened image to reduce the page dimensions before saving the image as a PDF file.

Edit:

The problem arises from the creation of the PDF file and is not specific to the CAL format, although that format is often used for images such as engineering drawings that have unusually large page sizes.
