Very Large Assemblies

[JohnSullivan]

A general question on how very large assemblies are managed.

We started a new project a few years ago and with the new powerful computers we decided to have a top level assembly with "everything" in it. Piping, electrical hardware, I mean everything!

We are using Dells with 12 g's of ram and 64 bit etc. I'm sure others have top level assemblies of their product in Pro.

At the user conferenceI attended a presentation on Simp Reps etc.

Buta question is; f I use simp reps in a drawing, does the whole assembly come up in RAM?

Ifit does come up, it tends to be slow and clunky, even when in simp rep mode.

I understand your concern.
In WF4 Process Assemblies using Geometry or Graphics reps on the drawing
it will retrieve the assembly in Master Rep when the drawing is retrieved,
If you retrieve the Process Assembly Rep alone, it will only bring in the
expected rep. Then retrieving the drawing using the same rep, the full
Master Rep of the assembly is retrieved.
The nasty thing about this is that you are able to create a drawing on a
32-bit system using a Geometry Rep and save it. But your might not be able
to open it again, due to memory needs.

I have not testet if this is the case for "ordinary" assemblies.

The Master Rep does not need to be in the drawing. I have some assemblies
others cannot open without retrieving a simplified rep.
To check the drawing to see if you have used the Master rep (WF 4.0) RMB
in the field of the drw radio button to properties, drw models,
set ad rep, make sure none of the views are set to master rep. If you have
a parametric parts list it will be running on the rep you had active when
you brought the table in.
One of the reasons empty rep is used.If you have any assembly cuts in the
model try to remove them if possible.
This means you have to sacrifice displaying some of the detail in some of
the sectional views.
Envelope parts can be created to reduce the needed Ram in simplified reps.
make sure you do not have any .crc files being created.

I'm still on WF 2 but I'm curious what you see when you go to Set/Add Rep in WF 4. In WF 2, I see all the reps in the assy listed, whether I have used them on the drawing or not.

I just ran across an issue where I needed to know if a particular rep was using on the drawing and I couldn't figure out a way except by checking the view properties on each view or by doing INFO-DRAWING VIEW on each view.

We are moving to WF 4 soon (scheduled date has passed more than once).

For any particular simp. rep., no, the entire assembly is not brought into session, but be careful with the drawing. If you use multiple simp. reps. in a drawing the components pulled into session are additive. So if you make a view of a rep with half the assy and add a view with the other half of the assy, you have the entire assy. In session.

I am running thru a drw now for an example. Opened a drw not using any
simplified reps. Created a rep called 01-Working.
I can go into Properties Models and set the rep to 01-Working, now when I
add a view it is of 01-Working.

For WF 4.0 double click the view, go to view states, simplified reps.
01-Working and it will replace the rep with 01-Working
It will warn you if you have associated views they will be replaced too,
such as projections, aux. etc.

If the Smart parts list was using the mater rep you will need to go to
repeat regions Model/Rep, select the table, select the model,
open, select 01-Working, confirm, and now the parts lists is reading the
rep 01-Working.

RMB to properties in the field of the drw, select drw models, remove rep,
master rep.

Next and important is to erase not displayed, this will remove the models
not used in the 01-Working rep from Ram.
Although with the way Pro-E code is written it may not clear the memory
being used. Next session of pro if you open only the rep
discluding models not wanted in ram or them drw you can see a significant
difference. Keep in mind drws can be effected by
the graphics card slowing functions.The more sheets cross sectionals and
detail will tax the Graphics card.

I have tried geometry and graphic reps in past versions but did not like
the results of detail, maybe they have improved it. Something like using
read only parts and assemblies that do not regen.

I also have Auto-Regen turned off so the views do not constantly regen. In
extreme cases views can be temporarily hidden as to free up graphics
taxing

You should be able to do the same in WF 2, I have used this many years.
