Import File

Allows you to transfer data from different file formats into the current scene.

To replace the current scene with the contents of a file, use File > Open. The PTC Granite format is also supported, but because there are no options, it is not listed in the option window.

Note: An intermediate file gets generated during file translations of all supported formats. The intermediate file has a Translating_source file name prefix and appears in a temporary directory until the translation operation completes.

WIRE Options

Programmers can access wire files via the Alias OpenModel library.

From within Alias you can open an older wire version. Rename older wire files to keep the older file format version and begin working in the latest version of Alias. Supported entities include surfaces, curves, and polygon sets.

Keep Windows

Imports windows.

Keep Cameras

Imports cameras.

Keep Lights

Imports lights.

Keep Shaders

Imports shaders.

Replace Shaders by Name

When importing shaders (Keep Shaders turned on), you can choose to replace the incoming shaders with shaders in the currently set User Library location. Replace Shader by Name only works with shaders that have the same name.

This option is not visible if Keep Shaders is turned off.

Note: By default, when you import objects, any incoming shaders having the same names as an existing shader get renamed by appending a # suffix to its name. This avoids name clashes between shaders. You can instead merge incoming shaders with existing shaders that have the same base-name by turning on Ignore # suffixes and merge.

For more information, see the Replace shaders by name.

Keep Animation

Imports animation. Determines whether to retrieve animations or only models. The default is ON.

When selected, both models and animation are retrieved. A window that contains an animated camera is retrieved with the model.

When not selected, only models are retrieved.

Keep Background

Imports backgrounds contained in a wire file.

Keep Construction Options

Prompts you to Accept the construction options contained in the wire file.

Keep Render Globals

Imports the render globals set for the wire file into the system, overriding the current settings.

To set render globals, use Render > Globals.

Keep Layers

Imports the layers you set in the wire file.

Keep Variants

Imports variants.

Keep Normals

Preserves vertex normals in the file. When this option is not selected, vertex normals are ignored, which means that they are recalculated during rendering.

Warning: When vertex normals are imported, they are “frozen” and are not updated. Vertex level editing, such as moving one vertex in relation to its neighbors, can make the frozen normals invalid, so subsequent renderings will not be correct. However, object-level editing (such as translation, rotation, or proportional scaling) does not cause these problems.

Input Units

Specifies the major linear unit for the incoming file.

Scale Factor

Specifies the scaling factor for this save.

Split Period Surfaces

Splits a periodic surface into multiple surfaces.

Axis Conversion

Converts the imported file to either a Z-up or Y-up coordinate system. For example, if you import an .fbx file created by an application that defines the Y axis as pointing up by default, such as Autodesk Maya, you can set this to Z Up Axis to correctly orient the object in Alias.
For more information see Transfer Maya polygon objects to Alias.

Transfer Maya polygon objects to Alias

You can exchange subdivision geometry between Alias and Maya using the FBX file format.

When transferring these objects between Alias and Autodesk Maya, be aware of the following:

  • To display G0 creases added by the Alias Subdivision Crease Edge tool, turn on Smooth Mesh Preview after loading the file in Maya.
  • To preserve creases in Maya polygon objects in Alias, turn on Smooth Mesh in the Maya FBX Export options before exporting geometry from Maya.
Note: You can also use the .obj file format to exchange geometry between Alias and Maya, however the .fbx file format provides better results.

Export polygon objects to a .fbx file

  1. In Maya, select the polygon object you want to transfer to Alias.

  2. Choose File > Export All or File > Export Selection.

    The Export All or Export Selection dialog box appears.

  3. In the Export Options, under General Options, select FBX export from the File type list.

  4. To ensure that the creases in your object are preserved in the exported file, Smooth Mesh must turned on before exporting. To do this:

    • Click Edit preset.

    • In the Edit export preset window, click Geometry and ensure that Smooth Mesh is turned on.

    • Click Close.

  5. Click Export Selection, name your file, and then click Export Selection.

Import the .fbx object into Alias

  1. In Alias, choose File > Import > File > .

  2. In the Import File Options window, select FBX Options from the list.

    Ensure that Import Subdiv is turned on.

    Note: Since Alias has the Z axis (not the Y axis like Maya) pointing up by default, the model will appear rotated on its side in Alias. You can change this by setting the Axis Conversion to Z Up Axis in the Import Options. For more information, see FBX import options.

  3. Click Import.

Pro/E Render import options

The Pro/ENGINEER Render translator converts the triangle data of the Pro/ENGINEER Render format into Alias meshes.

Note: It is important that the Pro/ENGINEER designer assign each part of an assembly a different color, so that each part will become a separate mesh in Alias. The colors are also translated into simple Alias shaders and these shaders are assigned to the appropriate objects.

Group

Imports objects as a single group for easier manipulation.

Input Units

Indicates the units of the Pro/ENGINEER Render coordinate data, so that the data is properly converted to the linear units set in Alias.

Scale Factor

Changes the size of models stored in the Pro/ENGINEER Render file format as you import the file.

Keep Normals

Vertex normals in Pro/ENGINEER Render files all point towards the inside of objects. For rendering purposes in Alias, these normals must point towards the outside of objects. Consequently, the translator flips all vertex normals during the translation.

The vertex normals of meshes are usually recalculated by the Alias renderer before it renders meshes. By default, the normals assigned to vertices in the Pro/ENGINEER Render file are “frozen” so that they are used by the renderer rather than discarded and recalculated. This allows the renderer to produce a better quality rendering.

To suppress this behavior, deselect Keep Normals so that the renderer discards the Pro/ENGINEER assigned normals and recalculates them.

Warning: If vertex normals are retrieved, they are considered “frozen” and they cannot be changed, so vertex level editing, such as moving one vertex in relation to its neighbors, may invalidate the vertex normal since it will not be updated, and subsequent renderings will not be correct.
Note: Object level editing, such as translation, rotation, and proportional scaling are still valid operations on frozen normals.

Merge Vertices

By default, the translator may merge the vertices of triangles along apparent shared edges. If two vertices have the same x,y,z position within a tolerance and have the same normal within angular tolerance, they are merged into one vertex. This allows Alias to do smooth shading across the edges. If two vertices have the same x,y,z position, but have different normals, then these vertices are not merged to maintain the hard edge.

If this option is not selected, no vertex merging occurs and all edges are rendered “hard”.

If selected, the Position/Normal menu becomes available.

Position/Normal

Determines how vertices and normals are merged.

List ItemDescription
POSITION + NORMALvertices and normals are merged based on their x, y, z position.
POSITIONvertices only are merged based on their x, y, z position. Normals are not merged.

Position Tol. (units)

Specifies the tolerance used for comparing vertex positions. The value specified is in the same units as the data (specified in the Input Units option). For example, if you specify 0.01 MILLIMETERS from the Input Units menu, the tolerance for comparing vertex positions is 0.01 millimeters.

Note: If you change the units from the default inches, then the default tolerance of 0.0001 may have to be changed to make sense for the units specified.

Normal Tol. (degrees)

Specifies the tolerance used for normal comparisons in degrees and is the angle between the normals of two vertices. The default is that two vertices will be merged if their positions are equal within tolerance and the angle between the normals is less than 1 degree.
