#### *class* Ansys.ACT.Automation.Mechanical.AdditiveManufacturing.AMBuildSequence

Bases: [`object`](https://docs.python.org/3/library/functions.html#object)

An AM build sequence contains a minimum of two steps - a heating step followed by a dwell step.

All sequences must begin with a heat step and end with a dwell step.

## Overview

### Methods

NameDescription[`GetStep`](#AMBuildSequence.GetStep)Gets the build sequence step at the 1-based step number.### Properties

NameDescription[`CombineSteps`](#AMBuildSequence.CombineSteps)Gets or sets the Combine Sequence Steps flag. \[Default = False\][`CombinedDurationType`](#AMBuildSequence.CombinedDurationType)Gets or sets the combined heating duration type. \[Default = ScanTime\][`NumberOfSteps`](#AMBuildSequence.NumberOfSteps)Gets or sets the number of steps in the build sequence. \[Default = 2, Minimum = 2, Maximum = 31\]<a id="property-detail"></a>

## Property detail

### *property* AMBuildSequence.CombineSteps *: [bool](https://docs.python.org/3/library/functions.html#bool) | [None](https://docs.python.org/3/library/constants.html#None)*

Gets or sets the Combine Sequence Steps flag. \[Default = False\]

An exception is thrown if the EnableBuildSequence property is not True.

<a id="AMBuildSequence.CombinedDurationType"></a>

### *property* AMBuildSequence.CombinedDurationType *: [Ansys.Mechanical.DataModel.Enums.AMHeatingDurationType](../../../../Mechanical/DataModel/Enums/AMHeatingDurationType.md#ansys.mechanical.stubs.v261.Ansys.Mechanical.DataModel.Enums.AMHeatingDurationType) | [None](https://docs.python.org/3/library/constants.html#None)*

Gets or sets the combined heating duration type. \[Default = ScanTime\]

An exception is thrown if the EnableBuildSequence property is not True.

<a id="AMBuildSequence.NumberOfSteps"></a>

### *property* AMBuildSequence.NumberOfSteps *: [int](https://docs.python.org/3/library/functions.html#int) | [None](https://docs.python.org/3/library/constants.html#None)*

Gets or sets the number of steps in the build sequence. \[Default = 2, Minimum = 2, Maximum = 31\]

An exception is thrown if the EnableBuildSequence property is not True. An exception is also thrown if the value is less than 2 or greater than 31.

### AMBuildSequence.GetStep(stepNumber: [int](https://docs.python.org/3/library/functions.html#int)) → [Ansys.ACT.Automation.Mechanical.AdditiveManufacturing.AMBuildSequenceStep](AMBuildSequenceStep.md#ansys.mechanical.stubs.v261.Ansys.ACT.Automation.Mechanical.AdditiveManufacturing.AMBuildSequenceStep)

```text
Gets the build sequence step at the 1-based step number.

     An exception is thrown if the stepNumber is less than 1 or greater than the number of steps. An exception is
     also thrown if the EnableBuildSequence property is not True.
