PTC then teachesusing the proven instructional design principal of ‘Tell Me, Show Me, Let Me Do’:• Topics are introduced through a short presentation, highlighting the key concepts.• These key concepts are then reinforced by seeing them applied in the software application.• You then apply the concepts through structured exercises.After the course, a Pro/FICIENCY assessment is provided to enable you to assess yourunderstanding of the materials. The assessment results will also identify the class topics thatrequire further review.At the end of the class, you will either take a Pro/FICIENCY assessment via your PTC UniversityeLearning account, or your instructor will provide training on how to do this after the class.

Precision Learning After the ClassEach student that enrolls in a PTC class has a PTC University eLearning account. This account willbe automatically created if you do not already have one.As part of the class, you receive additional content in your account:• A Pro/FICIENCY assessment from the course content that generates a Recommended LearningReport based on your results.

• A Web-based training version of the course, based on the same instructional approach of lecture,demonstration, and exercise. The Recommended Learning Report will link directly to sectionsof this training that you may want to review.

Please note that Web-based training may not be available in all languages. The Web-based trainingis available in your account for one year after the live class.

Exercise 1: Configuring a Milling Operation

ObjectivesAfter successfully completing this exercise, you will be able to:• Create manufacturing operations.• Select existing workcells when configuring machine tools.• Assemble fixtures.• Create coordinate systems when specifying machine zero positions.• Specify retract planes.

ScenarioYou need to configure an operation that involves specifying a machine tool by selecting apre-configured fadal workcell. You also assemble a fixture that represents the fadal machine tool.You configure the machine zero coordinate system for the operation. This involves creating anew coordinate system in the manufacturing model. This coordinate system references modelgeometry from the fixture assembly. Finally, you specify the retract plane relative to the machinecoordinate system.

Exercise 1: Different Methods for Assembling ReferenceModels

ObjectivesAfter successfully completing this exercise, you will be able to:• Assemble reference models using the Merge by Reference option.• Assemble reference models using the Inherited option.

ScenarioYou need to assemble reference models to two different manufacturing models. You start byopening the mold cavity manufacturing model and assemble the mold cavity part using the Mergeby Reference option. This option copies all the mold cavity geometry into one merge feature inthe reference model.You then open the cover manufacturing model and assemble the cover part using the Inheritedoption. The Inherited option gives you the flexibility to modify geometry and features on the inheritedreference part without changing the original cover part if required.
