## Description

***"Physical Component"*** is a MagicDraw customized stereotype used to specify *Block* elements with the property of system physical components.

In the *Physical Component* Specification you can find more useful properties than for simple block, for example Mass, Operation and Non-Operation Temperatures, Power Consumption, etc. 

The specification of *Physical Component* stereotype can be found in ***Library & Architecture*** MagicDraw model in *Customization* package:

## How to apply *Physical Component* Stereotype to a *Block*:

1. Create a *Block* element, name it (e.g. Sensor)
2. Open the *Specification* window of the Block (right click of mouse -> *Specification*)
3. Choose *Applied Stereotype* property, press '...', type *Block* and remove the tick near *Block* stereotype, press *Apply*:

4. Go to *Applied Stereotype* again, press '...', type *Physical Component* and add a tick near it, press *Apply*:

5. Now if you press the Specification of your element you will find some extra-properties (e.g. Mass, Placement, Lower Operation Temperature etc)
  
  It easier to find all the customized *Physical Component*'s properties if you press the *Categorized View* in element *Specification* window - all the specified properties would be at the end of the properties list:

## Revision of Subsystem *Physical Components* properties:

The specification of subsystem's physical components can be found in ***Subsystem Physical Elements Specification*** table (*Library & Architecture* model, *04 - Physical Structure & Simulation --> 04.0 - Physical & Software Elements Definition --> Subsystem Physical Elements --> Subsystem Physical Elements Specification*):

![](https://i.imgur.com/2P5ev9T.jpg)


**NOTE!** Not all the *Physical Component*'s' properties can be added/changed from the *Subsystem Physical Elements Specification* table. If you can't change a property from the table, go to the element's *Specification* window (right click of mouse on the element -> *Specification*).
