  1. I-deas Workflows in NX Presented by Mike Morse Technical Marketing

  2. I-deas Workflows in NX 6 • Question: • How many of my familiar I-deas modeling, assembly, and PMI functions and workflows are available in NX? • Answer: • Question: • Do I have to abandon my I-deas “Best Practices” and learn a complete new set for NX? • Answer:

  3. I-deas Workflows in NX 6 • I-deas ≠ NX • NX ≠ I-deas • Major Differences: • Interface • Fixed vs. Flexible • Units • SI Units vs. Metric / English • History Representation • “Bushy” vs. “Timestamp” • “Multiple Parts on Workbench” • Yes or No? • Parasolid Kernel • Partition/Boolean yielding multiple solids • Drafting • External vs. Integrated • Data Management • TDM vs. Teamcenter vs. “Native”

  4. I-deas Workflows in NX 6 • I-deas = NX • Most I-deas Workflows have Logical Equivalents in NX • Major Similarities: • “Sketch – Constrain – Extrude” • Hybrid Open & Closed Part Modeling • Freeform Surfacing • Drafting / Blending / Shelling • Copy / Paste / Replace / Reuse Features • Cross-over Modeling Features: • Sketcher; V-Sweep; Emboss • Cross-over Assembly Features • Assy. Constraints; Arrangements; Sequences • Interpart and Assembly Modeling • ACF vs. WAVE

  5. I-deas Workflows in NX 6: Topics • Interface (GUI) • New Parts (Units) • Part Navigator • Datums • 2D Sketch* • Selection Intent • 3D Curves • 3D Shapes • Primitive / Solid / Sheet • Boolean Operations • Copy / Paste / Replace Features (Reuse)* • Detail Features • Draft / Blend* / Shell • Modify Feature Parameters • Measurements & Expressions • Assemblies* • PMI* • 2D Drafting * *Demo

  6. Interface • Menus and Toolbars Based on Task • Modeling, Drafting, Assembly, PMI, Sheet Metal, etc. • “Resource Tabs” Access Part, Assembly, History, Web, Materials, Wizards, etc… • “Roles” Capture and Restore Interface Content • “I-deas” Role Exists for Transitioning Users • New Dialogs • Pinned to “Rail” • Consistent location • Consistent interaction • UNDO / REDO(!) • RMB “Gesture” Options for Common Functions • Extensive Customization Available • Menu / Toolbar Add or Delete Functions • User Created Toolbars • Keyboard “Hot Keys” • “TAPS” • Toolbar Locations Docked or Free • Optional New “Full Screen” Mode

  7. New Part • I-deas New Part includes Absolute CSys • Units are not an issue • (SI units used internally) • NX New Part based on Template “Seed Part” • Metric vs. English must be specified • Different Seed Parts for Different Applications • Model vs. Assembly vs. Drawing vs. NASTRAN… • Modeling may be done in ANY units • Analysis -> Units • I-deas may have multiple “Parts” on “Workbench” • NX may have multiple “Solids/Sheets” in one part; • Use File -> Import -> Part to add parts together • Use Assembly to display multiple parts at once • Use Window to switch between loaded parts

  8. Part Navigator • “One Stop” Feature Information / Editing Panel • Columns show Feature Name, Type, Modified Date, Alerts, Reference Sets, etc. • Use to Rename / Group / Suppress / Show – Hide / Reorder / Delete Features • Includes More than Feature Information: • Model Views, Cameras, Expressions, PMI, Drafting Sheets • “Details” Panel for Dimension Values • “Dependencies” Panel for Parent / Child Relations • Two Basic Display Modes: • “Timestamp” • Like I-deas “Linear” History Tree • Most Commonly Used • “Design View” • Similar to I-deas “Bushy” History Tree • Useful for Isolating Tool Features • Do you really need a “bushy” history? • “Rollback” and Insert Features anywhere. • “Drag and Drop” to reorder features. • Filter to Quickly Find Features

  9. Typical Modeling Workflow Design Target Body Sketch Section Design Tool Body Relative Datum or Datum CSYS Boolean Operation

  10. Datums • “WCS” – Unique, Dynamic “Work Coordinate System” • Optional Method for Positioning • Datum Axes / Planes / Coordinate Systems • Very Similar to I-deas • Many options for Datum Planes • Similar options for Datum Coordinate System • Representation equal to I-deas (planes, vectors, point) • Offset CSYS may be translated/rotated or vice versa • Use Datum CSYS as first feature for modeling • No Need for Reference Curves • Sketches persist as required • Optional Sketch Reference Curves do not participate in feature creation (Extrude, Revolve) • Sketch on Path orientation options similar to I-deas

  11. 2D Sketch • Unique Sketcher Task • Enhanced with I-deas input • Sketch on Plane or Path • Path must be used for V-Sweep • Horizontal / Vertical Reference • Curves change color when partly/fully/over constrained • May snap to grid • May create Reference sketch curves • “Construction” curves, not for feature creation • Degree of Freedom arrows vs. Show Free • Drag curves or Animate Dimensions to show free motion • Can’t Drag Dimensions • Automatic and Inferred Constraints

  12. 2D Sketch cont. • Curve creation very like I-deas: • Profiles, lines, arcs, circles, conic, splines, rectangles… • Intersect, mirror, offset, trim, extend, make corner, fillet… • No Need to “Focus” • Select edges directly • Projection to sketch plane is possible • Dimension values from Global Expressions • Curves may be grouped for easy reuse • “Fixed” text height; automatic orientation to view • Automatic reorientation of sketch plane to view • Local or Absolute origin • Sketches may or may not be absorbed – your choice • Sketch Plane / Path may be respecified

  13. Selection Intent • Concept Adopted from I-deas • Selection Intent “Toolbar” • “Snap Points” during sketching / positioning • Selection “Filter” (Solid; Face; Edge; Curve; etc.) • Selection Continuity (Single; Connected; Tangent; All) • Stop at Intersection; Follow Fillet • Select All / Deselect All • Selection by Group Name • “Quick Pick…” vs. “Reconsider” • Prioritizes selection options • Bodies vs. Features e.g.

  14. 3D Curves • Many options similar to I-deas: • Lines, Arcs, Splines, Conics, Polygons, Text • Optional Associativity • Intersect, Draw on Surface, Offset On Surface, Bridge, Circular Blend, Project, Cross- Section, Wrap, Unwrap, Helix, Law Curve, etc. • Extract, Mirror, Project, Combine Projection • Dynamic Spline Editing • Thru Points / Control Points / Degree • Enhanced spline curvature continuity (G0, G1, G2)

  15. 3D Shapes – Solids & Primitives • Solid = Closed Part • Based on Parasolids Kernel • Created from Closed Section(s) • Extrude / Revolve / Sweep / V-Sweep / Tube • Offset during creation of Extrude/Revolve simplifies sketch requirements • Created from “Primitives” (Design Features) • Block, Cylinder, Cone, Sphere • Quick Parametric Creation of Common Shapes • Hole, Boss, Pocket, Pad, Slot, Groove • Some Features Recognized by CAM • Created by “Sewing” Sheets Together • “Unsew” to Convert Solid to Sheets

  16. 3D Shapes – Sheets & Surfaces • “Sheet” = Open Part • Created from Open or Closed Section • Extrude / Revolve / Sweep / V-Sweep / Tube • Toggles allow sheets to be created from closed sections • Created from Multiple Open Sections • Mesh Surface • Many Options: Ruled, Through Curves, Studio Surface, N-Sided.. • Curvature Continuity Control Available • Created from Other Input • “Swoop”, Four Points, From/Through Poles, From Point Cloud, Bounded Plane, Law Extension, Silhouette Flange…

  17. Boolean Operations • Solids: • Unite / Subtract / Intersect / Split / Assembly Cut • Sheets: • Sew / Emboss Sheet / Trim Sheet or Body / Trim-Extend / Patch • Boolean may be specified during Feature Creation • If so, Boolean type may be changed later • Solids– Same as I-deas; except: • Original “Target” and/or “Tool(s)” may be Retained • Not Automatically Absorbed like I-deas • Sheets • May be Cut or Intersected by solids • May be “Embossed” by Solids (like Join w/Material Side) • Solids may be Trimmed or “Patched” by Sheets • Direction Toggles - Results like Material Side • Sheets may be Trimmed by Other Sheets • “Make Corner” Option Available w/Direction Toggles • May be “Sewn” Together into Larger Sheet or Solid • May be “Unsewn” to Give Sheets From a Solid

  18. Typical Copy/Paste Workflow Set Feature Timestamp Paste Body Copy Body Select Body Edit Datum CSYS

  19. Copy / Paste Features • Use “Instance Geometry” or WAVE to get Topology Only • Single Feature Associative back to Original Geometry • Use “Copy/Paste” to Duplicate History Steps • Body’s Features may be Selected from Design View • Allows Pasted History Features to be modified Independent of Original • May be Used Between Different Parts! • During “Paste” All Parent Dependencies Should be Indicated • “Copied” Features should be based on an Offset CSYS ONLY • Only one dependency needs to be satisfied • During “Paste” Expressions may be New, Linked, or Instance • “New” allows complete modification control • “Linked” is associative to original, but may be unlinked / changed • “Instance” is identical to original and may not be unlinked

  20. Instance Features & Geometry • Instance Features (Pattern) • Like I-deas Pattern • Feature Based (Hole, Slot, Boss, etc.) • Rectangular, Circular, Mirror • Individual Patterned Instances may be Suppressed • Instance Geometry • Like I-deas Feature Copy • Geometry Based (Sheet, Solid, Sketch, etc.) • Translate, Rotate, Along Path, From – To, Mirror • Use Within a Single Part

  21. Replace Features • Copy/Paste Adds New Features • Parent Dependencies need to be Indicated • Csys to Csys Positioning Like I-deas “With Relations” • Replace Substitutes One Set for Another • “Group” Features Together for easy Selection • Child Dependencies need to be Indicated • “Replacement” (New) Feature must exist before any Children of “Replaced” (Old) Feature in Timestamp Mode • Old Feature may be Retained or Deleted • All Child Dependencies Transferred to New Replacement Feature • Automatic, Tolerance Based Dependency Mapping. • Workflow Option: • Copy Feature(s) from Source Part • Paste into Target Part just before Features to be Replaced • Control Position with Csys to Csys • Replace Old Features with Newly Pasted Features

  24. Modify (Edit) Features • Double Click Feature to “Rollback” and Edit • To See Feature at Creation Time • To Reselect Geometry • To Change Values • To Toggle Results • “Handles” for Dynamic Editing • On Screen Value Dialogs Minimize Mouse Travel • Select Feature and RMB “Edit Parameters” • To Edit Feature in “Final” Part Context • Select Feature from Part Navigator • Use “Details” Panel to Change Values • Works with Sketches, too • “Drag and Drop” to New History Location • Cannot Place “Child” before “Parent” • Highlighting Shows Parent/Child Dependencies • “Dependencies” Tab Gives Expanded Information • Toggle Suppress/Unsuppress • RMB Toggle Show/Hide

  25. Measurements & Expressions • All Logical Measurements are Available: • Distance; Projected Distance; Radius; Angle; Tangency… • Geometric and Mass Properties • Measurements may be: • Associative; Recorded as Expressions; Checked against Requirements; Reused • Minimum Radius; Curvature and Draft Analysis; Wall Thickness; Dynamic Reflection Patterns • “Examine Geometry” like I-deas Part Diagnostics • Expressions Dialog Manages All Expressions: • Automatically Created by Features and Measurements • Manually Created by Users • Look up Values from Spreadsheet • Calculate with Common or Defined Functions • Link to Other Parts • Handles All Types of Units and Conversions

  26. Assemblies • Every “Part” can be an “Assembly” (.prt) • Add Components / Create New Parent / Create New Component … • Hierarchy Structure Like I-deas • Managed in Assembly Navigator • Suppress / Unsuppress • Component Display Managed by “Component Groups” • “Proximity” Component Groups • Component Positioning Adopted from I-deas Assembly Constraints • Replaces Older NX “Mating Conditions” • Exploded Views Available • Assembly Arrangements Adopted from I-deas Configurations • Constraints may be Arrangement Specific • Assembly Sequence Adopted from I-deas • Create Motion Envelope • Calculate Extraction Path • Comprehensive Interference Checking • Wrap Assembly gives Exterior Bounding Volume • Interpart Linked Geometry via WAVE (like I-deas ACF) • Position Dependent or Independent • Inter/Intra-Part Linked Expressions (like I-deas Part/Assembly Equations) • Partial Loading makes handling Large Assemblies Possible • Loading Controlled by “Reference Sets” (Solid, JT, Entire Part, etc.)

  27. 3D PMI & Model Views • 3D Product and Manufacturing Information (PMI) • Functionality Borrowed from I-deas • Datums, Dimensions, Notes and Symbols, GD&T, URL • Model View Based Documentation • Use Existing, Create, Modify, or Delete Model Views • PMI Orientation Based on Model View Plane or WCS • Section Cuts Through Solids • Crosshatching in Wireframe / Unique Color in Shade • Search & Report Options • Inherit PMI Types into Drawing • PMI & Model Views Managed in Part Navigator • Associated Objects Mode

  28. 2D Drafting • Integrated with 3D Design Environment • Common UI • Fully Associative • Template Based Layouts Speed Drawing Creation • Drag and Drop Sheet Size; Views; Border; etc. • Dimensions; Datums; GD&T; Sections; Annotations; Balloons; Automatic Parts List; • Shaded Views on Drawing • Assembly / Component Display Control • Hole Tables • Inherit PMI from 3D Model

  29. NX 6: Unique Workflows • WCS • Similar to I-deas “Workplane” • Persistent, Dynamic, Optional • Layers • (Do you think I-deas has layers?) • Helps Control Display and Manage Complex Models • Expressions • Similar to Part/Assembly Equations • May be used Within and/or Between Parts • Sketch and Boolean “Tool” Reuse • More Design Intent w/fewer Sketches in fewer Planes • Direct Modeling (Synchronous Modeling) • Parametrically Modify B-Rep Solids • No I-deas Equivalent • Assembly Reference Sets • Quick loading of Large Assemblies • Visualization • “Environments” • Enhanced Rendering w/Shadows, Textures, Reflections • Image Based Lighting • “Full Screen” and “True Shade” Mode

  30. I-deas Workflows in NX 6 • Question: • How many of my familiar I-deas modeling, assembly, and PMI functions and workflows are available in NX? • Answer: • Lots. (More than you might think.) • Question: • Do I have to abandon my I-deas “Best Practices” and learn a complete new set for NX? • Answer: • NO! Best Practices can migrate as well as geometry.
