**[accordion-item title=”Overview +” state=closed]**This two day class is a serious introduction to surfaces using NX. In this class we cover all the basics then some.

- Learn to use Spline’s vs radius curve geometry.
- Learn to use bounding boxes to control curves & surfaces that result from those curves.
- Learn to use Bridge & Studio Spline geometry.
- Learn how to use Conics.
- Learn to use Project Curve & Intersection curves for manipulating complex geometries.
- Learn to utilize Framing for Surface Development.
- Learn how to appropriate Tangent Constraints.
- Learn to use Compound Curves when appropriate.
- Learn to use Evaluation & Analysis functions.
- Learn to use Combine Projection and alternate techniques for building robust curve structures.
- Learn to use curves on surfaces.

**[accordion-item title=”Prerequisite +” state=closed]**It is assumed that participants of this two-day intensive have a working knowledge of Unigraphics NX part modeling and an interest in using surfaces.[/accordion-item]

**[accordion-item title=”Discussions +” state=closed]**

- Discuss surfacing principals and prepare users for the basics (people come from many backgrounds have used surfacing for years but never really understood the basics).
- Discuss modeling technique and robust building efforts for more modifiable part models.
- Discuss import geometry and techniques on managing external import data such as Alias or Rhino data in a product engineering environment.
- Compare Conic y=x^2 curve geometry to Spline or y=x^3 curve geometry and discuss when and where to use each example.
- Discuss workflow for creating softgoods to electronic housings.

**[accordion-item title=”Exercises +” state=closed]**

Design-Engine course presentations & examples involve approximately 12 specific surfacing examples to help participants utilize surface modeling techniques in Unigraphics NX. By understanding more than the basics, selection and proper technique users can set themselves up for expert technical surfacing master faster.

After learning about surfaces from an IGES perspective we create an Acco Swingline stapler that uses both swept and extruded surfaces.

With the exception of the stapler model, each exercise takes approximately an hour.

**IGES Exercise**

In this example we walk the participant through various IGES/STEP imports and look at how to manipulate subtract or add to that import data.

**Paper Floating in the Wind**

(four part boundary) In this exercise participants use three separate arcs to formulate on leg of four of a boundary surface. We use expressions to discover how to make the most robust boundary surface possible. Later we discover various offset surfaces then trim the geometry to make a Principles potato-chip. In this final rendition we look at Tangent and the various options for tangency to the surface.

**Acco Stapler Model**

This tutorial is broken up into five separate examples.

Skeleton model – WAVE linked models – Robust exercise – Ribs – prep for Tooling (we save this part for the Die Casting classes

To begin with the skeleton takes both swept and extruded surfaces. Later, we use WAVE link functions (Top-Down Design) where all the geometry works together to formulate the product. The participant is required not only to model the geometry, but make significant design changes to the form in under 10 minutes. As geometry fails, the participant is shown valuable tools for managing parent-child relationships. In the end we add ribs and look at making sure those are robust as well. Participants are challenged to model the original form more carefully next time paying close attention to what they dimension to in sketcher.

**Saddle**

In this surfacing example, participants look at various ways to intersect, project and create a similar form. We often look at the basics of G2 Continuity in this example looking at Zebra stripes and various analysis tools for evaluating light reflections.

**Hood Scoop**

In this surfacing example, participants look at various ways to avoid 3 part boundaries.

**Scallop Geometry**

Many products use scalloped geometry to protect buttons ect. In this surfacing example participants learn various ways to generate the scallop.

**Smile Tutorial**

In this surfacing example, participants look at various proving form techniques for ease of modifying the model. We make many changes to the model and compare conics & 3 degree curves in detail.

**Door pull Model**

Here we learn to utilize underlying curve geometry to create robust door pull. We modify this door pull into a refrigeration door pull.

**Kawasaki Fender Model**

In this surfacing example, participants look at workflow for building similar geometries.

**Febreze Model**

In this surfacing example, participants put it all together to formulate a product.
