When you create or edit graphics with an online UI to an NAE35 or NAE45, changes you make do not save if the graphic is too large. The total size of the graphic background, dynamics, and static text must not exceed 700K bytes. A typical size for an SVGZ graphic is 100–200K. You do not receive a warning that the graphic is too large to save. Transactions larger than 1 MB are rejected by the NAE. The size limitation includes a 40% overhead from the HTML wrapper around the save transaction.

Note: This size restriction does not apply to graphics that are created and saved through the online UI to an NAE55, NAE85, or SCT.

When you work with NAE35/NAE45 graphics, use the following equation to help keep your graphics at a manageable size:

(background image size x 140%) - 1 MB (1,048,576 bytes) = available space for graphic dynamic symbols and text blocks

Note: Each graphic symbol is 3,000 bytes.


Background size: 700,000 bytes

Background + overhead: 700,000 x 140% = 980,000

Total Space for symbols and text = 1,048,576 - 980,000 = 68,576

Total symbol and text elements = 68,576 / 3,000 = 22
