Several configuration variables are available to control the visible edge calculation settings. These variables either provide default settings ( MS_VISEDGE_DEFAULTS) or override the existing settings values ( MS_VISEDGE_OVERRIDES, MS_CVE_VISEDGE_OVERRIDES, MS_PLOT_VISEDGE_OVERRIDES, MS_EVE_VISEDGE_OVERRIDES).

MS_VISEDGE_DEFAULTS controls the default settings, these settings are otherwise extracted from the design file. You can still change these values through the user interface as desired. The default settings are applied when a design file is loaded and will be saved to the file when the "Save Settings" command is used (File > Save Settings).

The following configuration variables are provided as overrides. When used, these values always take precedent over the conventional settings and the corresponding user interface item is disabled. The balloon text for the disabled dialog box item indicates the details of the configuration variable override.

• MS_VISEDGE_OVERRIDES - Controls all of the visible edge processes.
• MS_CVE_VISEDGE_OVERRIDES - Controls the Cached Visible Edge (CVE) generation.
• MS_PLOT_VISEDGE_OVERRIDES - Controls the plotting visible edge filtering.
• MS_EVE_VISEDGE_OVERRIDES - Controls Export Visible Edge and reference file merge processing.

Each variable can specify one or more of the settings in the Export Visible Edges dialog by including the keywords and values in a comma separated list. The keywords are all directly related to the (English) items in the dialog.
