Layer Security

Overview

FM ACCESS provides security controls for two types of layers: Global Layers managed through the Administrative panel, and Local Layers managed at the Document level.

Global Layers

• Security settings are configured in the Administrative panel

• Only Administrators can modify Global Layer properties, including styles (Toolset Properties)

• Changes to Global Layer properties cannot be made locally, even by users with Edit permissions (except for the layer content on the drawing)

Local Layers

• Created within specific Drawings

• By default, only accessible to the layer owner

• The layer owner retains full access rights that cannot be revoked (regardless of the permissions set)

• Layer ownership cannot be transferred, but can be claimed by the Administrator

Permission Types

FM ACCESS supports two types of permissions for both Global and Local Layers:

1. View Permission

   • Allows users to view the layer and its content

   • Must be explicitly granted to users or groups

2. Edit Permission

   • Allows users to modify layer content

   • Automatically includes View permission

   • For Local Layers, also enables modification of Layer Parameters and Security settings

Permission Management

• Permissions can be assigned to individual users or groups

• Local Layer owners can manage permissions for their layers

• Users with Edit rights to a Local Layer can modify permission settings

• Permissions are assigned by selecting users or groups for each permission type
