Assembly and Coordinate Management with

OSD and WM

Introduction

I am not a good teacher!

Engineer – by definition I don’t have any social or communication skills - Therefore you must ask questions if anything is conceptually unclear – resolve now or later as appropriate

Really, Really, Really, Really important to have a good understanding of this material!

Simple concepts – very difficult in combination (coordinate systems, write/modification permissions, load level, etc.)Work with examples on web-site between classes and ask questions!

Review ALS Coordinate Systems-ALS Global, ALS CAD, and Beamline (local) coordinate definitions

Difficulties Working with multiple coordinate systems-Where is it and why? -More

than 1 location requires multiple copies of an assembly (NO!) -Beamline Coordinate assemblies load coincident

Parts and Assemblies

- What they are and how they are stored -OSD Instance and Contents Files

-Multiple Instance Files-Parent and Individual References

How to …

- Loading, storing & working with multiple coordinates and assemblies

Working with Coordinate Systems

-There are 3 “types” of coordinate systems used: ALS Global, ALS

CAD, and BL (Local) Coordinates (Refer to ALS Note M7957 on web)- ALS Global Origin located offsite (deep in the earth’s crust) – center

of the storage ring at (1500,3500,2500)m (x,y,z)

- ALS CAD Origin located at nominal beam height in the center of the storage ring

- BL (local) Origin located (usually) at specific beamline radiation source point

Working with Coordinate Systems

By default, we (should) work in BL coordinates - Models stored in BL coordinates share a common source point and orientation in OSD – load coincident or “on top” of each other.- How do you view neighboring beamlines or models that are stored

in “their” BL coordinates?

Working with Coordinate Systems

Any point in any coordinate system can be translated (mapped) to an alternate coordinate system.

Transparency Visual AidPTC Moment-

“Wouldn’t be great if you could move (map) an assembly to another coordinate system without needing a duplicate copy? Would that be helpful? Who here could use something like this?”

Bottom line - We can use OSD Part and Assembly attributes to accomplish this

Parts and Assemblies

I

Parts and Assemblies consist of “Contents” and “Instance” Files

- PART “Contents” File= geometry, physical attributes (color, density, etc.), View Sets

- PART “Instance” File= Independent geometry location and instance specific attributes (shared parts) information

What is a PART?

Parts and Assemblies

I

Assemblies, like parts, consist of “Contents” and “Instance” Files

- ASSEMBLY “Contents” File = Parts list (P1, P2, etc.),

View Sets

- ASSEMBLY “Instance” File= Assembly location & assembly specific child PART and SUBASSY location

What is an ASSEMBLY?

Parts and Assemblies

Example –

Load assy 1, note location of p1 and p2

Load p1 and p2 at root, note locations, move p2 to 3m and save

Load p2 to confirm location (3m)

Load assy 1, note location of p2, move p2 (4m) within assembly and note icon

Save, clear, reload assembly and note location

Clear, load p2 at root and note location, machine feature, save, clear

Load assy 1, note feature appearance

What’s going on?

-Modified part instance, assembly instance, contents?

How does this help us?

Use parent assembly to locate any models in the relevant BL coordinates

- Parent assembly can have independent location (instance) information for subassemblies/subparts that do not affect the individual assemblies/parts location information
