# IPCB_MaxMinHoleSizeConstraint interface

A hole size rule (`TRuleKind.eRule_MaxMinHoleSize`) that defines the minimum and maximum hole size of pads and vias.

```csharp
public interface IPCB_MaxMinHoleSizeConstraint : IPCB_Rule
```

**Namespace:** PCB · **Assembly:** Altium.SDK.Interfaces

**Inherits:** [IPCB_Primitive](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Primitive.md) → [IPCB_Rule](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Rule.md)

## Remarks

The limits are either absolute sizes ([`MinLimit`](#minlimit) and [`MaxLimit`](#maxlimit)) or percentages ([`MinPercent`](#minpercent) and [`MaxPercent`](#maxpercent)); [`AbsoluteValues`](#absolutevalues) selects which pair the rule checks. A new rule checks absolute sizes, with a minimum of 1 mil and a maximum of 100 mil.

The rule checks pads and vias on the multi-layer. Pads without a hole are not checked. For a slot or rectangular hole, the width and the height of the hole are checked separately. When the rule checks absolute sizes, back-drilled vias are not checked.

## Properties

| Property | Type | Access | Description |
| --- | --- | --- | --- |
| [AbsoluteValues](#absolutevalues) | `bool` | get; set | Whether the rule checks the absolute limits ([`MinLimit`](#minlimit) and [`MaxLimit`](#maxlimit)) instead of the percentage limits ([`MinPercent`](#minpercent) and [`MaxPercent`](#maxpercent)). |
| [MaxLimit](#maxlimit) | `int` | get; set | The maximum hole size, in internal units (10,000 per mil), checked while [`AbsoluteValues`](#absolutevalues) is true. |
| [MaxPercent](#maxpercent) | `double` | get; set | The maximum hole size as a percentage, checked while [`AbsoluteValues`](#absolutevalues) is false. |
| [MinLimit](#minlimit) | `int` | get; set | The minimum hole size, in internal units (10,000 per mil), checked while [`AbsoluteValues`](#absolutevalues) is true. |
| [MinPercent](#minpercent) | `double` | get; set | The minimum hole size as a percentage, checked while [`AbsoluteValues`](#absolutevalues) is false. |

### AbsoluteValues

Whether the rule checks the absolute limits ([`MinLimit`](#minlimit) and [`MaxLimit`](#maxlimit)) instead of the percentage limits ([`MinPercent`](#minpercent) and [`MaxPercent`](#maxpercent)).

```csharp
bool GetState_AbsoluteValues();
void SetState_AbsoluteValues(bool argValue);
```

**Type:** `bool` · **Access:** read/write

The default is true. It also selects which limits [`DataSummaryString`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Rule.md#datasummarystring) and [`DescriptorString`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Primitive.md#descriptorstring) show.

### MaxLimit

The maximum hole size, in internal units (10,000 per mil), checked while [`AbsoluteValues`](#absolutevalues) is true.

```csharp
int GetState_MaxLimit();
void SetState_MaxLimit(int argValue);
```

**Type:** `int` · **Access:** read/write

A new rule has 100 mil.

### MaxPercent

The maximum hole size as a percentage, checked while [`AbsoluteValues`](#absolutevalues) is false.

```csharp
double GetState_MaxPercent();
void SetState_MaxPercent(double argValue);
```

**Type:** `double` · **Access:** read/write

The percentage is the hole size relative to the via diameter, or to the smaller of the pad's X and Y size. A new rule has 80 (percent).

### MinLimit

The minimum hole size, in internal units (10,000 per mil), checked while [`AbsoluteValues`](#absolutevalues) is true.

```csharp
int GetState_MinLimit();
void SetState_MinLimit(int argValue);
```

**Type:** `int` · **Access:** read/write

A new rule has 1 mil.

### MinPercent

The minimum hole size as a percentage, checked while [`AbsoluteValues`](#absolutevalues) is false.

```csharp
double GetState_MinPercent();
void SetState_MinPercent(double argValue);
```

**Type:** `double` · **Access:** read/write

The percentage is the hole size relative to the via diameter, or to the smaller of the pad's X and Y size. A new rule has 20 (percent).
