Substitute

Edit Round

Modify Analytic

> Recognition Pattern Recognition & Editing

Symmetry Recognition & Editing

> Propagation Combine transformations with

recognition

> Other Editing Features Attach

Remove

39

> Set of Geometry-Based Editing Tools Users work directly with geometry No underlying feature definitions are needed Tools work the same on imported geometry vs.

legacy Pro/ENGINEER models.

No underlying feature definitions are impacted

> Flex Modeling Creates Parametric Features Geometry selection methods and the geometry manipulation

techniques are stored as parametric features

Obey all standard parametric feature rules

> No New Geometry Creation Users of Creo Parametric will continue to create

new geometry with standard parametric features.

No a standalone modeling system

> The Foundation of Direct Edits in Creo Direct


The Basics

Flex Modeling Tab Shape Selection Tools

Other Editing Tools

Recognition Tools

Primary Editing Tools

Geometry Rule Selection

41

> No Design Intent Edit non-native geometry files

Assign design intent

Control surface sets as features

> Obsolete Design Intent Old Parametric Model is difficult to use/modify

Part design requirements have evolved, new control required

Why rebuild if you can assign new design intent instead?

> Emergency Changes Have to make a change right now!

Parametric change can be evaluated later


Use Case

42

Selection in the Flexible Modeling Extension

43

> Selection Filter Geometry is the default

Use Surface Region filter to isolate one contour of a multi-contour surface

> Shape Based Selection Hover over Rule to preview selection

Cut, Boss and Round Optionally add secondary surfaces

Multiple shape rules can be combined via control key

Any surfaces can be excluded via control key

Rules are alive like all selection rules

Selection

Boss

Boss With Secondary

44

> Geometry Rule Based Selection Use Geometry Rules dialog to define sets of related surfaces for a

single operation

Once the desired surfaces are highlighted, use MMB/Ok to select

Presented rule options are context sensitive Coplanar appears for only planar selected surfaces

Coaxial appears for conical/cylindrical surfaces, etc.

Apply and/or logic to any presented rules

Selection

45

> Dragger Collectors Origin collector remembered position of the

dragger Orientation collector allows separate

orientation of the dragger Dragger positions allow reproducible

regeneration of the feature Note: Free move uses no collectors only the

final geometry location is stored.

Move Tool Basics

Dashboard and References Tab

Reference collectors

for location and

orientation of dragger

Move Options

Moved Surfaces Collector

Excluded Surface Collector

(Use for Advanced Selection)

Special Collector for Moving Curves and

Datums with the Geometry Set

> Keep Original: Keeps original geometry in original

location; makes a copy

> Excluded Surfaces Collector Allows the use of advanced selection

techniques to exclude surfaces from the selection set.

With Dragger

By Dimension

By Constraints

46

> Move Any Number of Surfaces Move surfaces via multiple, recorded

steps Define dragger placement & orientation Define step size

Move with no steps: Free Move Only final position is recorded

Apply simple dimensioning scheme

3 Translations, OR 1 Rotation

> Parameterize Imported Models Apply parametric control to key surfaces Enable design studies Develop families of imported models

> Re-Parameterize Existing Models Define new design intent on older models Explore what-if scenarios not possible

with existing design intent

Move & Move by Dimension

47

> Position Geometry using Assembly

Constraints Works well in combination with Free Move

Position geometry approximately first

Then use constraints to finalize position

Standard constraint types available.

Distance constraints result in parametric dimensions

Move by Constraints

48

> Create Side Surfaces Creates a discontinuity at the specified edge

Geometry is simply extended starting at the selected edges

> Extend and Intersect Select edge(s) at extension surface boundary

System will choose one of two surface to extend

Will break tangency

Use Next solution to see other surface extend

51

> Attach When unchecked, system will leave the moved geometry as an open

quilt

May be necessary in certain situations Perform additional operations, build new geometry, then attach later

> Create Round Geometry When unchecked, system will not attempt to recreate rounds at the final

location

May need to manually create rounds or modify some geometry first

> Maintain Solution Topology Controls how the system reacts to changes in topology around the flex

move feature.

When checked, the system will fail the feature if the system cannot apply the remembered solution because of a topology change

When un-checked, the system try to apply the remembered solution, but switch to the first found default solution if possible.

> Split Extending Surfaces Collectors Select surfaces you want to extend in the extending surfaces collector

Select surfaces performing the split in the splitting surfaces collector These surfaces will be used to separate the extending surface from its

surrounding geometry

Use Flip to get the complementary solution

> Modify Cylinders, Spheres, Torii and Cones Only one surface at a time

Only one type at a time

> Allows Same Geometry Control Same Attachment panel as move

Same Options panel as move

Modify Analytic

56

> Replace One Set of Surfaces With Another Remove and recreate rounds

Define bounding edges for overhang solutions

Keep substituting surfaces

Substitute

57

> Selection Use Round recognition or the system analyzes round

geometry from selected round surface automatically

Does NOT rely on round feature definitions Works the same for imported or native geometry

> System Calculations Existing rounds are removed and recreated at

constant radius (including variable radius rounds)

Options: Unattach Leave interfering rounds alone

Remove rounds

Edit Rounds

58

Offset

The Big Brother of Core Offset

> Uses the Same Technology as Move Removes and recreates rounds Extends surfaces to attach to surrounding

geometry

> Allows Same Geometry Control Same Attachment panel as move Same Options panel as move

> Different Workflow Tool calculations done as you enter the tool, even

with no drag

59

Modify Analytic, Substitute, Edit Round, Offset

60

Move, Keep Original,

Do Not Attach

> Extends One-Sided Edges of the Quilt to Attach No need to embed the quilt in the solid

> Use with Move, and Do Not Attach Option Allows you to edit the quilt in the final location before attaching Always extends one-sided edges to try to find geometry Multiple solutions possible if multiple depths are possible

> Use with Constructed Quilt Geometry Build a new quilt in the desired location, attach using this tool

Attach

Attach Quilts in Difficult Locations

Attach

61

> Enhancement of Creo Elements/Pro 5.0 Remove Tool Performs same geometry analysis and extensions Same options for Excluded Contours and multiple solutions

> New options: Keep removed surfaces makes a copy useful for complex selection

sets Leave open removes the selected surfaces and does not extend

adjacent surfaces to close. New Quilt when working with surfaces, this option creates a new

quilt from the extended geometry Surface when working with solids, this option creates the surface

extensions as a separate quilt, unattached to the model

Remove

62

> Geometry Mirror with Move Technology Extends and attaches surfaces of the mirrored geometry

Creates rounds at intersection edge in new location to match original

Allows mirroring of curves/datums with geometry

> Allows Similar Geometry Control Bounding edges with multiple overhang solutions

Attach geometry

Create rounds

> Only Option is to Split Extending Surfaces

> Workflow like Standard Feature Mirror

Mirror

64

Pattern & Symmetry and Recognition and Propagation

65

> Recognize Like Geometry in Any Part If the pattern is linear or radial, this will be detected

Spacing and number of instances will be editable subject to the geometry operations succeeding

If there is no pattern to the spacing, then spatial option is provided

> Restrict Recognition (Pattern Rec. Only) Use surface selection

Use a sketch

Pattern and Symmetry Recognition

66

> Used with Pattern Recognition on Geometry Change multiple like surfaces simultaneously

Available with most Flex Modeling Tools in the Options Panel: Move (all types)

Modify Analytic

Offset

Edit Round

Propagation to pattern members is controlled by the pattern definition

Propagation
