Each courseis organizedintomodules,eachcoveringa general subject. Eachmodule contains topics,~ P T C ' Uni ve rsity-..Jwitheach topic focusedona specific portionof themodule subject. Eachindividual topic in the module is dividedinto the followingsections:Concept - This sectioncontains the initial introduction to the topic andis presentedduring the classlecture as anoverheadslide,typically withfiguresandbullets.Theory - Thissectionprovidesdetailedinformationabout contentintroducedin the Concept, andis discussedin the classlecture but notshownonthe overheadslide. The Theory sectioncontains additionalparagraphs of text, bullets,tables, and/or figures.Procedure - This section provides step-by-step instructions about how tocomplete the topic withinPro/ENGINEER. Procedures are short, focused,andcover a specific topic. Procedures are foundin the Student Handbookonly. Not every topic has a Procedure,as there are knowledge topics thatcontainonlyConcept andTheory.Exercise - Exercises are similar toprocedures, except that they aretypicallylonger, moreinvolved, andusemore complicatedmodels.Exercises also may cover multiple topics, so not every topic will have anassociated exercise. Exercises are foundin the separate Exercise Guideand/or the online exerciseHTML files.The firstmodule for certaincoursesisknownasa "processmodule." Process modules introduce you to the generic high-levelprocesses that will be taught over the span of the entire course.Procedure IExercise HeaderTo make the exercises andprocedures (referred to collectively as "labs") asconcise as possible, each begins with a "header." The header lists the nameof thelab, a brief scenario, the workingdirectory,the file youare to open,and theinitialdatum display.The followingitems are indicatedin the figureabove:1. Procedure/Exercise Name - This is the name of the lab.2. Scenario - This briefly describes what will be done in the lab.3. Close Windows/Erase Not Displayed - Areminder that youshouldclose any open files and erase them frommemory. These icons havebeenadded to the left side of themain tool bar: Click Close Window LEl until the iconis disabled.:..-:rt-:.. Click Erase Not Displayed loo.' and then click OK.4. Folder Name - Thisis the working directory for the lab. Lab filesarestoredin topic folders. The path to thelab filesis: users/studentlcourse_folder/module_folder/topic_folderIn the example, Extrude_Features is the topic folder,and should be setas the WorkingDirectory. To set the workingdirectory, right-click the folder in the folder tree orbrowser, andselect Set WorkingDirectory.5. Model toOpen- Thisis the file tobe openedfromthe workingdirectory. In the above example, extrude_1.prt is the model to open.Themodel couldbe a part, drawing, assembly, anso on. If youare~ P T C ' Universityexpected to begin the lab without an open model,and instead create anew model,you will see Create New. To open the indicatedmodel, right-click the file in the browser andselect Open.6. DatumDisplay Setting - The initial datum display youneed to setis shownusing icons. For example, [111/ ~ ) ( ) ( ~ ~ ~ indicates that youshoulddisplay only datumplanes. Datum axes, datumpoints, anddatum coordinate systems should be disabledin this case.

A chainis a collectionof adjacent edges andcurves that share common endpoints. Chains canbeopen-ended or closed-loop, but they are always definedby two ends.Chain TypesThe followingare the different typesof chains that canbeused to selectedges: Intent chain - Enables youto select edges basedon theirintent. Forexample, say youuse anintent chain to select the four edges of a squarecut for purposes of rounding them. If the square cut is redefinedinto ahexagon cut, theintent chainwill automatically addthe two additionaledges androundthembecause your intent was toroundthe edges of thecut. Had yousimply selected the edges one at a time androunded them,the roundfeature wouldeither fail or not round the newly added edges. One-by-one - Enables you to select adjacent edges one at a time alongacontinuouspath. Tangent chain - Enables you to select all the edges that are tangent toananchor edge. Surface loop - Enables you to select a loop of edges on a surface. Surface loop fromto - Enables you to select a range of edges from thesurfaceloop.

Theresultingcurvelieson the surface. By default,one offset valueis provided. However, youcancreate additional offset values and thenlocate those offset values along theoffset edge as desired. The offset value locationis a ratio of the entire offsetline length. For example, if you want to locate an offset value at the midpointof the curve, youwouldspecify a Locationof 0.5. Youcanalso locate theoffset values on the curve endpoints. In the upper-right figure,the curve hastwo offset values defined, one at eachendpoint.For each offset value, youcanspecify the distance the curveis offset fromits original curve. In the upper-right figure, the curve is offset on one side by2.00, andon the other side by1.00. This distance value canbe measuredusingthe followingdistance types: Normal toEdge - Measures offset distance normal to the boundary edge. AlongEdge - Measures offset distance along the measurement edge. To Vertex - Starts offset curve at the vertex and parallel to the boundaryedge.Module 2 I Page 60 2009PTCCreating Offset Curves Normal to a Surface~ P T C ' UniversityYou canoffset a curve on a surface, normal to a reference surface. Theresultingcurve is raisedoff the surface by a distance,as shownin the lowerfigures.You can specify this offset distance using the followingmethods: Offset value - The distance the curve is offset from the surface. Unit Datum Graph - A datum graph witha constant X-lengthof 1.0 isused to specify the curve offset. The resultingcurve is offset at a constantvalue as definedby the Scale valuein the dashboard. In the lower-rightfigure,a unit datum graph is used to offset the curve. As a result,the offsetis the same alongthe entire curve. Optional Datum Graph - The curve offset is determinedby anoptionallyspecifieddatum graph. Whenanoptional datum graphis defined,thesystem uses the Offset value as a multiplier.

Ellipses are created with construction lines for the major and minor axes.These constructionlines canbe used to dimension or constrain the ellipse. 2009PTC Module3 I Page3~ P T C ' University. Youcan dimension an ellipse by its major andminor axes,evenif theellipse is created on anangle. To create these dimensions, you can selectthe axes constructionlines anddimension them directly. You can also dimension an ellipse using the major axis (Rx) andminor axis(Ry) dimensions. These radius values are measured along the axes fromthe ellipse toits center. Themajor axisis always thefirst axis placed,regardless of size compared to the minor axis. You can create an ellipse at any angle, based on the placement points forthe major axis.

In theupper-right figure, onlythe endpoints are dimensioned. However, in the lower figures, the bottomintermediate point is also dimensioned. Youdo not have to dimension anypoints of a spline if both endpoints snap to Sketcher references.There are special dimensioning schemes for splines: Tangency Angle Dimensions - You can create tangency angle dimensionsfor endpoints and intermediate points of a spline. Changing the angle valuewill alter the shape of the spline. To create this dimension, select the spline,the spline endpoint, and a reference for tangency, then middle-click to placethe dimension in the desired location.
