Symbol Comparison Tab

The Symbol Comparison Tab is used to define the layers on which the auto symbol identification routine should be run

Here you specify the sheets and layers that should be included in the, by entering them into the text box in the format "Sheet\Layer"

Clicking the button adds the defined layer to the list, clicking the button removes the selected layer from the panel above.

The "Exclude Layers" checkbox excludes the layers from your search and searches all the layers within a sheet, this is useful when complete symbols are compounded up from multiple simple symbols on different layers of the same sheet, as it helps to prevent erroneous symbol identification.

The "Inlcude By Visibility" checkbox options allow you to simplify the Auto Symbol Identification to layers that are invisible/visible or both. With both "All Visible Layers" and "All Invisible Layers" checked, every drawing will have the Auto Symbol Identification run on every sheet and layer.

Note that selecting this disables the "Exclude Layers" check box.

The button opens the Model Selection window. This is used alongside the layers to ensure that complex symbols are not erroneously identified as several simple symbols, by allowing you to specify the symbols that should be matched to, that the system will match to in desceding order of their complexity.
