- What is Altair Inspire?
  Inspire is a concept design tool, which you can use to run structural optimization, finite element analysis, motion analysis, and additive manufacturing analysis.
- Videos: Getting Started with Inspire
  A series of videos introducing the view controls, 3D modeling, structural analysis, topology optimization, and PolyNURBS.
- Licensing Features
  Some ribbon tabs are associated with license features. Depending upon the tab you have invoked, additional units may be drawn. These features will be checked out for the duration of the session.
- Workspace and Tool Belts
  Learn how to customize the workspace and tool belts.
- Find and Search for Tools
  Quickly find and open the tools that are available on the ribbons.
- File Import and Export
  Learn how to import geometry and export results.
- Select and Edit
  Review techniques for selecting and editing objects.
- Adjust the View
  Change the view in the modeling window using the mouse or view controls.
- Move and Snap
  Translate, rotate, and align parts and other objects using the Move tool and snaps.
- Screen Capture
  Record a video or take a snapshot of the screen.
- Units and Measurement
  Change the default unit system, create custom units, and measure geometry features.
- Browse and Organize
  Browse and organize all of the entities in your model.
- Run a Simulation
  Use the Analyze icons that appear on various ribbons to run and view the results of a simulation.
- Help and User Assistance
  Learn about the forms of help and user assistance available from the product.
- Preferences
  Modify the workspace display, default keyboard shortcuts, and other settings.
  - Open the Preferences
    Open the Preferences window, where you can search for and customize application settings.
  - Search the Preferences
    Search for a setting to show the closest match in the Preferences window. Or use the API to display selectable search results in a dropdown list.

Tutorials
Start using Inspire with our interactive tutorials.
Variables
Create and assign variables to parametrize a model. This allows you to quickly iterate and compare design concepts by tweaking the values of the variables.
Parametric Modeling
Create parametric sketches, geometry, and PolyNURBS with construction history and variables.
Implicit Modeling
Create implicit models with primitives, lattices, point clouds, fields, offsetting, Booleans, inverting, smoothing, morphing, and filleting.
Structures
Set up your model and run a structural analysis or optimization.
Motion
Set up and run a motion analysis, plot the results, and export the results.
Fluids
Prepare and run a computational fluid dynamics simulation.
Design Explorer
Evaluate designs by using geometric variables and applying a design-of-experiments (DOE) or optimization method. We recommend fully constraining your sketch when sketch variables are used in the design exploration.
Manufacture
Set up and run a basic porosity or thinning analysis.
Print 3D
Prepare and run an additive manufacturing simulation, and export a file for 3D printing.
Rendering
Adjust the materials and environment of objects in the scene to create a photorealistic image.
Inspire Python API
Learn how to access the Inspire Python API including online help, quick start demos, and the Extension Manager.
Reference
View the glossary, frequently asked questions, and errors and alerts.
Keyboard Shortcuts and Mouse Controls
Learn keyboard shortcuts and mouse controls for common operations.

Preferences: Print 3D

Define preferences for 3D printing.

Undercut Options


Preference	Description
Minimum support area	Use to define the smallest area for which supports should be generated. Areas smaller than this will be assumed to be self-supporting due to their small size and will not display a support preview, even if one would generally be required due to the undercut angle.
Angle undercut	Any region with an undercut angle less than or equal to the value defined here will be shown as requiring supports.

Support Options


Preference	Description
Support spacing	Use to adjust the spacing between supports.

Run Options


Preference	Description
Run in model directory	Enable this option if you want to store run history in the directory where the model is located rather than the run history path.
Run history path	Specify the default location where the run history is stored.
Number of CPU cores	The number of CPU cores used during analysis runs. For larger models, significant time savings can be achieved by using at least two cores to perform the calculation.

Analysis Legend Colors


Preference	Description
Printing	Select the legend color scheme for Print 3D analysis results.
