Title: Revision Clouds
Post by: shaunfella on April 07, 2015, 12:00:43 PM
Hi guys,
New to the forum.  Have been a designer in a few different companies and each time the revision procedure has differed.

Can I ask the forums opinion on this;

If you remove a complete detail/ note/ item etc from the drg - do you cloud that area even though there is nothing there? Some companies may cloud the area and add 'DETAIL/ NOTE.. REMOVED'

Be interested to read what the rest of you do.

Thanks
Shaunfella

nothing there = no cloud

something to see = cloud + revision number

I've seen it all three ways. The simple answer is to follow your company's standard.

I was brought in to shake things up a bit in the CAD department as there has been a bit of a 'well thats the way we've always done so that's how we do it' that has caused a lot of accumulative issues

Whatever you decide, IMHO, there has to be some indication that there was something deleted, either by cloud or by note or both.

This is also my feeling..why reissue a dwg with no indication that anything has changed!

if a detail is removed....that can or should be added here...on our sheets

not an empty cloud...

empty clouds can cause confusion

An empty cloud, if it is on a plan or a detail sheet, can only mean that something has been removed. No confusion at all.

Again, my feeling is that it needs to be flagged up that something has been amended. However some clients insist on only that particular revision's title .i.e.  Approved for Design, with no additional text. Therefor we cannot annotate as such in the revision block........

OR that something did NOT PLOT....so there is potential for confusion

now if this was years ago...one might even see erasure marks on the blueprints...then it would be clear something had been erased

Do any you guys use Comment Resolution Sheets, or similar, at all?

no

However ...I have seen revision cloud AND  a giant 'watermark' indicating
DETAIL NOT USED and a big X across such a detail

for people who don't know how to read plans and addenda or bulletins, that's just over analizing. There should be additional documentation for revisions that spells out what the changes are. Deletions would be noted on those.

Personally, I would note that detail has been deleted but I have submitted many empty clouds and there has never been any concern about changing that procedure in the 14 years I've been here. Certainly, if there was any confusion in the field we would have changed our procedure.

I've typically used Michael's approach when a revision requires removing a detail as no longer to be used.  Large "X" across the detail, and revcloud it.

An empty revcloud would confuse the contractors I've dealt with, and I really don't expect the guys in the filed to keep _all_ earlier copies of the prints to cross reference an empty cloud with what was there the previous rev.

They shouldn't have to. The documentation included with the drawing revision should cover it. The guys in the field shouldn't even think about it. The drawings have been reviewed and they should have all the necessary information to build whatever it is they are building. It's not their responsibility to question the drawings. I know that doesn't happen but we shouldn't have to jump through hoops for the idiots.

Thanks very much for your responses folks.  As I have experienced already there are many ways to skin a cat.  I'll make a decision based on some of the methods detailed in here and standardise it.

Can see this forum being of good use to myself!!

Usually a triangle or teardrop with number, description, and total number of on sheet.

That way there is no dispute what changed and how many time, they see in description what the revision was, and see how many times it made.

This is in context of change order, etc.....  where money is involved in some fashion due to change.
