Cracks in the System
Cybersecurity threats don’t always kick the door down—sometimes, they slip in through the cracks. This month, we’re spotlighting three subtle but serious security risks that could be undermining your defences right now.
In this blog article, we are going to take a look at different electrical symbols and symbol types within AutoCAD Electrical.
Electrical symbols within AutoCAD Electrical consist of an attributed block with required and optional electrical attributes that defined the symbol type. A feature within AutoCAD Electrical called ‘Symbol Builder’ is used to define the symbol and component type, including the block objects and insertion point.


The different symbol types available are:
The component type list can be adjusted to include/remove specific component types by amending the attribute template files within the specified library path within ‘Symbol Builder’.
An example of an attribute template files for a circuit breaker is shown below:
AT_HP_CB
where AT = Attribute Template, HP = Horizontal Parent and CB = Circuit Breaker
AT_VP_CB
where AT = Attribute Template, HC = Vertical Parent and CB = Circuit Breaker
AT_HC_CB
where AT = Attribute Template, HC = Horizontal Child and CB = Circuit Breaker
AT_VC_CB
where AT = Attribute Template, HC = Vertical Child and CB = Circuit Breaker
Depending on what symbol type and component type is selected, this will provide the user with the specific required and optional attributes.
If the component type description is required for the new component i.e. (PU) Power Distribution Unit. This is achieved by adding the new table to the catalogue database (Project Tab > Other Tools drop down), select the required catalogue that is being used and within the existing table ‘_FAMILY_DESCRIPTION’, Add the table name and description as shown in the example below:

Once the attribute templates have been set up, they will also be available when saving custom symbols within the symbol builder using the file naming convention in AutoCAD Electrical as shown in the example below:

If you are an Autodesk Vault user in the mechanical engineering and manufacturing industry, you are likely familiar with the challenges of managing design data. While Vault provides a solid foundation for storing and organising design data, it falls short in some critical areas. You might have noticed this if you ever wanted to automate workflows or configure company-specific rules and processes in Vault. Let’s dive into these challenges and possible solutions.
