Communicate Your Vision

Alias Surface makes it easy to create highly realistic

models. You can shade and light models to com-

municate your design vision more clearly, and

conﬁrm that your surfaces meet exacting standards.

Reviewers can evaluate high-quality imagery that

reﬂects a range of materials and colors. The result

is quick and conﬁdent design-review decisions—

without time-consuming renderings.

Speed Up Processes

When engineering teams need to redo surfaces,

it delays projects and can result in unintended

changes to your models. Alias Surface supports a

highly streamlined workﬂow that lets you control

design intent further in the product development

process. You can exchange design data with

engineering CAD software, such as Autodesk®

Inventor®, to preserve design integrity. And you

create such high-quality, Class-A surfaces in Alias

Surface that engineering teams don’t need to

recreate them.

process. Quickly manipulate your model, exploring

variations on 3D forms without rebuilding geometry,

or make real-time modiﬁcations in design reviews.

Shape objects dynamically with these powerful

tools:

Lattice Rig—Sculpt geometry by manipulating a•

customizable lattice created around an object.

Transformer Rig—Use curves and surfaces as•

controls to modify or constrain portions of

existing geometry.

Bend—Bend geometry using a curve to control•

deformation.

Twist—Twist geometry around a single-axis curve.•

Conform—Conform geometry to the shape of•

another surface.

Rapid Prototyping

Build physical prototypes more eciently from

digital models. With rapid prototyping, you can

develop and reﬁne designs before committing

to production. Print in 3D using STL output for

stereolithography by exporting data to computer

numerical control (CNC) machines. Alias Surface

supports 3D printing in color.

Design Modeling

The concept

development phase

demands close

collaboration between

designers and engineers

to produce concepts that

are new, yet technically

feasible.

Take your 3D models to the next level. Evolve concepts

through a creative, iterative process.

Advanced Surface Creation Tools

Advanced tools for creating surfaces ensure that

your surfaces maintain positional, tangent, or

curvature continuity with surrounding surfaces—for

high-quality results ready for manufacturing.

Semiautomated Surface Modeling Tools

Do surfacing work faster. Autodesk Alias Surface

provides semiautomated tools for creating clean,

complex surfaces ready for tooling. For example,

you can create a ﬁllet and accompanying ﬂange in a

single operation.

Explicit Surface Control

Maintain control over surfaces, creating the lightest,

highest-quality geometry. Choose single-span

(Bezier) geometry or multispan nonuniform rational

B-spline (NURBS) geometry, then deﬁne the

number of spans and the degree of created surfaces.

Curve on Surface Paradigm

Precisely trim and form edges of new surfaces.

Share trimmed geometry among modelers while

retaining precision.

Direct Surface Modeling

Sculpt surfaces directly by adjusting surface control

vertices. Alias Surface’s curve-based tools let you

deﬁne a shape at its edges, or you can use direct

modeling to adjust the shape at any point. Maintain

complete control of Bezier surfaces to achieve the

exact form and surface quality you need.

Precision Surface Modeling

Surface Evaluation

Verifythequalityofcreatedsurfaces,including

curvature and radii analysis. This ensures that

geometry can be used by CAD programs and will

meet manufacturing requirements.

Align Tool

Accurately line up surfaces and curves, directly

controlling geometry alignment. Achieve high-

quality surface modeling and Class-A surfaces with

new math capability for surface construction.

Bezier Surface Fillet

Create and manipulate Bezier surface ﬁllets to

address Class-A surfacing requirements. Provide

superior surfaces with strict Bezier output.

Develop the Class-A surfaces engineering teams need to

create tooling. Dynamic modeling capabilities help you

develop Bezier or NURBS geometry in less time.

Scan Data Workﬂows

Import and conﬁgure data from 3D scanners to

visualize and reverse-engineer consumer product

or vehicle models. Alias Surface helps you simplify

and remove data with tools for cutting, smoothing,

automatic hole ﬁlling, and reducing mesh. The

software can handle large models with millions of

polygons, so you can extract and evaluate shape and

form.

Feature Extraction

Spend less time creating and updating surface

models. This specialized tool lets you extract feature

information from scan data quickly.

Reverse Engineering

Analysis Tools

Get help ﬁne-tuning your models with Alias Surface

analysis tools. They provide instant numerical or

graphical feedback on surface quality.

Hybrid Modeling

Integrate NURBS data into scan data. With Alias

Surface, you can evaluate and reﬁne the resulting

hybrid model without resurfacing an entire model—

saving time and eort.

Surface Reconstruction

Automate the multistep process of ﬁlling holes

in scan data. Alias Surface recognizes exterior

curvature through user-deﬁned sections by

generating a mesh patch.

Move easily between the analog and digital worlds. Autodesk

Alias Surface lets you incorporate changes to a physical model

into your digital model.

Interactive Shading

Use shading models to enhance realism and to

evaluate surfaces and design form. Autodesk

Alias Surface reduces time-consuming renderings

by providing immediate visual feedback on

your designs. The software supports material

color, texture, glow, incandescence, bump, and

displacement, and lets you quickly verify surface

conditions such as curvature maps, zebra stripes,

and draft angles.

Annotation Tools

Evaluate and review designs with ease. Take advan-

tage of your entire screen space to work with just the

necessary interface aspects. Alias Surface provides a

full set of annotation tools such as bookmarks, full-

screen capabilities, and pencils and markers.
