2D DrawingSolid Edge V192D Drawings may take two forms:CopyrightedMaterial2D Sketches show the outlines and locations of multiple shapes or parts to be designed.2D Profiles must be closed shapes with no entitiesinside or crossing the sketch. The sketch at the rightmay be used to create a part by selecting specificshapes then “cleaning up” the outline by trimminginner curves. The final shape must be a single series ofconnected lines and arcs.Complete MasterSketch. (Cannot beused to create a partin this form).CopyrightedMaterialProfile must be aclosed “loop” withno internal lines.Resulting 3Dobject with depthadded.CopyrightedMaterialPortions of the Master Sketch are copiedwhen creating individual part features.CopyrightedMaterial32

Solid Edge V192D DrawingAssembly Sketches (Layouts)CopyrightedMaterialThese are used to define the criticalgeometry in a series of mating parts.Elements from the master sketch maybe selected to create the individualparts. This assures that the parts are thecorrect size and are located in exactlythe right place.Elements of the part sketches whichare derived from the master sketch maybe associated (linked) back to the master sketch. This means that any changein the master sketch will update all theassociated parts.CopyrightedMaterialPortions of the sketch were used tocreate the base of the pillow block assembly.Other portions of the same sketch willbe used to create the opening for thebearing.Modeling the bearing is done by selecting the inner circles. The bronze bearing is created as a separate part.CopyrightedMaterialThe final assembly is shown with the parts modeled exactly as they fit.As you can see, 2D sketches are the basis for much of the design and part creation process. These sketches canbe very general at first then, exact sizes can be assigned later. All parts associated to the master sketches will resize to the new dimensions. Each part will be the right size and in the right mbly view.33

2D DrawingSolid Edge V19Starting a 2D DrawingCopyrightedMaterialAny new object starts with a 2D sketch. Complexobjects can be designed more efficiently by creating amaster sketch with part geometry defined by a seriesof overlapping lines. As the part shape evolves the 2Dlines are used to add material or cut away material.Simpler shapes may be designed by staring directlywith the Protrusion or revolved Protrusion icons.Master sketches give more control over the modelingprocess.Component Sketches are placeholders for existing parts or for related items yet to be designed.CopyrightedMaterialOnce Sketch is started, The Ribbon Bar displays prompts and options.A Reference Plane must be selected. Or, a new reference plane must be defined as a 2D drawing plane.A pop down dialog box allow the selection of alternateplanes for starting the sketch.CopyrightedMaterialCoincident Option starts a sketch on one of theexisting reference planes.CopyrightedMaterial34

2D DrawingSolid Edge V19CopyrightedMaterialDraw MenuConstraints MenuCopyrightedMaterialDrawn items may be changedby editing lengths, angles,diameter/radius, etc.Edit MenuWhen items are connected,changing one item may causeanother entity to change in anunexpected or unwanted manner.Placing constraints on a 2Dsketch helps to ensureEngineering raining sketches is an important step in the design process. Many features may be changed as the designevolves. Making sure the master sketch changes in a predictable manner is critical.Constraints are a combination of geometric (parallel, vertical, concentric, tangent, etc.) and dimensional lengths.The first tutorial (chapter 1) introduced some of these ideas.36

2D DrawingSolid Edge V19Constraining Sketches.CopyrightedMaterialConstraints help to insure that changes to a sketch behave in a predictable manner. Editing causes shapes tochange and parts often must be re-sized for weight, strength, appearance or other reasons. All of the changescan result in some weird shapes unless constraints are in place to control the changes.Two types of constraints are used: Dimension Constraints and Geometric Constraints.Dimension ConstraintsSmart Dimensions are applied to individual elements.A single pick will dimension a line, circle, etc.CopyrightedMaterialA pop down menu for other dimension types is shown.Distance between and angle between relate two items.Driving dimensions control a part feature.Driven dimensions are controlled by other dimensions. Each type is a different color on the screen.Geometric ConstraintsCopyrightedMaterialThe geometric constraint icons are shown.Choosing and applyingconstraints is a matter ofplanning which elementsmust remain fixed inrelation to other elements that are allowed tochange.CopyrightedMaterialTurns display of geometric iconsOff/On40

We want to be able tochange the circle size and keep thehexagon shape.CopyrightedMaterialLines are connect constrained andtangent constrained.Changing the circle size produces in anunexpected result!CopyrightedMaterialWhat other constraints need to be addedto fix the problem?41

2D DrawingSolid Edge V19Editing 2D sketches.CopyrightedMaterial2D drawings are often constructed using basic shapes then editing the shapes to get the final forms.Fillet is a rounded corner. Chamfer is a beveled corner.Offset may be one side or both sides.CopyrightedMaterialSizes and locations may be fixedby placing dimensions.Objects may be moved or resized by changing the dimensionvalue.CopyrightedMaterialMove pop-down displays several related editing commands.CopyrightedMaterialThe rectangle shape was modified using the fillet editing command.42

Solid Edge V19Trim2D DrawingCopyrightedMaterialInner circular arcs wereremoved using trim.Extend will only workif there is a “stopper”boundry.CopyrightedMaterialExtend would not work butTrim would work.Construction LinesCopyrightedMaterialRegular lines may be toggled to construction line status (and back).Construction lines are not considered aspart of a profile sketch.Using construction lines is a good wayto anchor geometry and locate circlecenters, etc.CopyrightedMaterial43

2D DrawingSolid Edge V19Grid and Grid SnapCopyrightedMaterialPlacing a grid on the screen enables additional drawing accuracy controls. By setting a useful grid spacing andtoggling Snap To Grid, the start and end points of lines, centers of circles, etc. can be placed accurately.Grid is very useful when an item must be placed relative to an existing point. Re-set the grid zero then measure over to the new point.Toggle GridOn/Off with thescreen icon or useTools .GridGrid Ribbon Baris shown.CopyrightedMaterialGrid settings dialogGrid display On/OffSnap to GridOn/OffSet Grid 0,0 to newlocationSet Gridto OriginCopyrightedMaterialGrid Options Dialog BoxSets major line spacing,Minor spaces per major,colors, etc.A typical decimal inch setting is shown.Working with architectural layouts, a typical setting might be:Major 1 footMinor 12 (1 inch)CopyrightedMaterial44
