>> Advanced techniques

Benefits of the Resolve Environment>> Provides all the tools available in Pro/E to fix a failure

>> Encourages failures to be fixed immediately

>> Makes models more robust and flexible

>> Improves modeling skills

Becoming Proficient with Resolve>> Key skill for Pro/ENGINEER users

>> Practice on test models

>> Dont wait until you have a failure on a production model

Why Good Features Go Bad>> Intersection of features is no longer valid

>> Missing References

>> Improper feature definition

>> Pattern Restriction no longer satisfied

>> Assembly failures due to missing components

What Happens When Features Fail

Do not save a model with suppressed failed features !

Resolve Feature Menu appears

>> Undo Changes, Investigate, Fix Model, Quick Fix

>> Failed and subsequent features not regenerated

In the File Menu>> Save, Save As, Rename, Erase are not available

Failure Diagnostics Window appears

>> Overview, Feature Info, Resolve Hints

How to Approach Resolving a Failure

Things NOT to do>> Automatically select Undo Changes

Steps to fixing a failure

>> Determine which feature failed

>> Determine why it is failed

Undo Changes is OK if you accidentallychange the wrong feature

Investigating the Failure

>> Typical regeneration failure

>> How to investigate and fix typical failures

Feature Conflicts with Another Feature

>> Re-evaluate the geometry and the features used

>> Quick fix

New (failed feature)

>> Suppress failed feature temporarily

>> Fix Model

Missing Assembly ReferenceIf the hole on the block is modified to rectangular hole. The bolt will not find axis alignment

constraint and the ASM will fail.

Quick Fix

Redefine & select new placement references

Original Assembly

Bolt Missing Reference

Modify Block

Missing Feature Reference

Similar to Missing Assembly Reference, except

Refers to references of a particular feature

Caused by changes made outside of assembly

Two types of features to discuss

Assembly Features

Part Features

Plug

Resolving Missing Feature Reference

Plug Redefined outside of assembly, so cut failsRedefine Cut to use new references

Should have used Replace in Intent Manager!

What is the Backup Model?

Last saved version of the model on the hard drive

If you saved very recently, this may be good enough

What if you have not saved recently?

Automatic snapshot at each Regeneration

Will cover this in more detail in a few minutes...

Using the Backup Model

Very powerful tool, especially when:

You are not so familiar with the model

Or not so familiar with the particular feature that has failed

Can be accessed in the Investigate and Fix Model menus

First lets talk about Investigation using the Backup Model

Investigation Using the Backup Model

First step - Identify the failed feature

Can be very difficult!Backup Model provides visual details

Crucial to understanding the failure

Appears in its own sub-window

All the tools the Current Model offers, and more

Can Investigate both models side-by-side

Fix Model using the Backup Model

Also appears in its own sub-window

Allows you to work on any feature in the entire model Redefine, Reroute, Create, Insert, etc

Work on the pre-failure model

Changes are actually applied to the current model

Obtaining a Backup Model

Last Saved Version

Is it recent enough?

Environment - Make Regen Backup

Snapshot with every regeneration Also a config.pro file option Regen Backup Using Disk = Yes

May take longer with large models

Save before risky operations

Restoring Dimensions

Under-utilized option in the Fix Model Menu

Restores dimensions to original values

Can choose which ones to restore

Dont need to panic about Undo Changes
