Precision LearningPrecision Learning in the ClassroomPTC University uses the Precision Learning methodology to develop effective, comprehensive classmaterial that will improve the productivity of both individuals and organizations. 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.

Precision Learning RecommendationsPTC uses a role-based training approach. The roles and the associated trainingare graphically displayed in a curriculum map. Curriculum maps are available fornumerous PTC products and versions in the training section of our Web site athttp://www.ptc.com/services/edserv/learning/paths/index.htm.

Please note that a localized map may not be available in every language and that the map above ispartial and for illustration purposes only.Before the end of the class, your instructor will review the map corresponding to the course youare taking. This review, along with instructor recommendations, should give you some ideas foradditional training that corresponds to your role and job functions.

Objective 1: Creating the Stapler Base

ScenarioSeals, a company that manufactures staplers, is planning to introduce a new hand stapler. Thestapler has sheetmetal mechanical parts and plastic covers. The design team of your companyhas created the product structure and based it on the top-level assembly structure created in CreoParametric. You are assigned with the task of designing the four major components - Base, Handle,Magazine, and Plunger. You will design these parts and review the assembly components with thetop-down design approach in mind.In this exercise, you will examine the existing HAND_STAPLER.ASM and some of its top-downdesign components before creating the necessary geometry in BASE.PRT.

2. Notice the datum planes defined with dimensionsfor the four components of the stapler assembly,which are the Base, Handle, Magazine, andPlunger.

3. Notice the Pin axis and the Staple Centerdefined with an axis and a plane, respectively.

4. Notice the published geometry features for eachof the stapler assembly components.

5. Review the list of declared items in the skeletonmodel.
