# Physical Member functions | OpenStaad Python

> Groups several analytical beams into one physical member, so a continuous column split by intermediate nodes is designed as a single unit.

Every function is a method of the session `s = ops.connect()` (`from openstaad import ops`).

print(result)
```

## Set/Assign

### SetPhysicalMemberUniqueID

Sets the unique string ID (GUID) for the specified physical member.

> **Nota:** Este método no es compatible con modelos físicos.

##### Parameters

- **nPhyMembNo**: Long variable for holding the physical member number ID for which the GUID is intended to be set.
- **szGUID**: String variable for holding the GUID to be set.

##### Return values

- Returns nothing. The GUID is set for the specified physical member.

##### Example

```python
from openstaad import ops

# Instanciar el módulo Geometry
s = ops.connect()

# Asignar un GUID al miembro físico número 10
s.SetPhysicalMemberUniqueID(10, "123e4567-e89b-12d3-a456-426614174000")
```

s.DeletePhysicalMember(1)
```

## Select

### ClearPhysicalMemberSelection

**Description**

Clears the physical member selection.

**Parameters**

None.

**Returns**

None: This function does not return a value.

**Example**

```python

### SelectMultiplePhysicalMembers

Selects multiple physical members in the current model.

This function allows you to select several physical members at once by specifying their numbers. The selection can be used for further operations or queries within the model.

##### Parameters

- **PhysicalMemberNosArray**: Array of physical member numbers to select. If the array is null or empty, no members will be selected. (Long)

##### Return values

- Returns nothing. The specified physical members are selected in the current model context.

##### Example

```python
from openstaad import ops

# Instanciar el módulo Geometry
s = ops.connect()

# Seleccionar múltiples miembros físicos con los números 1, 2 y 3
s.SelectMultiplePhysicalMembers([1, 2, 3])
```

### SelectPhysicalMember

Highlights the specified physical member in the current model.

This function resalta (selecciona) el miembro físico especificado por su número, permitiendo realizar operaciones o consultas posteriores sobre él.

##### Parameters

- **nPhyMembNo**: The physical member number to highlight/select.

##### Return values

- Returns nothing. The specified physical member is highlighted in the model context.

##### Example

```python
from openstaad import ops

# Instanciar el módulo Geometry
s = ops.connect()

# Resaltar el miembro físico número 5
s.SelectPhysicalMember(5)
```
