Each plant that you design can have different insulation specification needs. You can create and edit plant insulation specification files with Smart P&ID Insulation Specification Manager. Insulation specification files end with the extension .isl.
The New command prompts you to save the current file and then creates a new specification file. You can save insulation specification files with the other reference data, or wherever you want, by using the Save As command. The insulation file associated with a plant is defined in Smart P&ID Options Manager in the reference data settings. You can switch between plants and specifications files by using the Open Database command.
You can also edit some of the properties that are associated with an entire specification file by using the Options command.
