Yea, I would have to agree, too... why put that much time and capital into something that you won't see a return on?

I find also, that as the resident tech support guy for all CAD software (including software we don't even USE in my firm!) for 3 dif. companies in this building... that it's much easier to troubleshoot if we're all doing relatively similar tasks.  I hate going to an engineer's station, here, trying to figure out what is going wrong, sitting down, and looking through, going "what the heck..." and having to figure out just how he's working and organizing everything before I can make sense enough to find out why a certain thing is going wrong.

That really only applies to the occasional WEIRD circumstance, rather than the "did you update the xref", "make sure PSLTscale is set to 1, and LTscale is 0.5", "Try ATTSYNC on the block"  type of regularly asked questions.

One thing to remember, as the development of the standards progressed, more automation was introduced, as more automation was introduced, adherence to the standards became easier.

As employees learned that when they adhered to the standards, their job was easier, employees embraced the standard, offered suggestions for improvements, and we had weekly office meetings for an hour or so to go over specific areas of the standard.

Each employee was given a day. That employee was tasked with providing instruction to the rest of the department on the proper use of a specific area of the standards. We had about 30 different types of drawings and more often than not, we would refer to a specific drawing, the standards for that particular drawing, the proper programming tools to use, and the expected result of doing so.

In the end, we all learned, and it was a well rounded staff that knew exactly what to do in almost every situation.

Guidelines for revolving door Cad shops. While I'm the only drafter/eng. (yeah, I said eng., what of it) here, I adhere to the standards I've learned over the years in these Cad shops. I'v got a little pile of Manuals/Handouts from fairly large companies that have exacted their standards from years of experience. I take what I need from them, plus a little common sense goes a long way as well. It's a lot easier to program towards drawing automation when you know there will be no deviation from layer to layer, block name to block name, etc..

I have worked for companies that had little/none standards, and the spaghetti mess is usually so far imbedded by the time anyone realizes standards are needed, the cost effectiveness to implement them is way off the map.

  This is why I am thinking baby steps with my office.

There are two sides to that coin.
When I started here there was no automation or custom tools to speak of.
I waited till I had been in the position for about 2 years to really learn what we needed and I developed and tested the tools I wanted the drafters to use.

One day I loaded everything up and sat down with each person to show them how it all worked and we went over do's and don'ts so they knew where we needed to be.  We pretty much abandoned using all older drawings as they were no longer compliant, this way the old stuff would not creep in to the new stuff.

It wasn't without pain, but it made for a sharp transition, and it seems easier to set the drafter back so he rethinks everything then fight item by item to get them to comply with new methods.

Since then I try to time major customization changes with software upgrades and hit the users all at once (but not all users at the same time, usually spaced out over a week or two depending on project status). I think that people tend to adjust to a large change better then an endless series of smaller changes, but thats just me.  Plus you will need a thick skin as stubborn drafters dig out the torches and pitchforks!   :evil:

I've created tons of little specialty apps, just to correct some known consistent inconsistencies for a client or two. But then their is the "Brute-Force" method of grabbing an entire drawing, and putting it on a layer (as a loose example), just to meet some automation parameters. It just takes a little bit of "up front engineering" (my favorite saying BTW), to be able to tackle that kind of monster, one scaly bit of it at a time.

It may be something you have to do, but it makes me shudder...   :-o

Of course we have had clients that had that as their drafting standard.   :ugly:

My company is one of those with a gazillion layers, all different colors, and at least a hundred different plot files.  I don't know if they have any dimension standards because I frequently get drawings with exploded dimensions, imperial scaled drawings with metric dimensions, etc.

So to keep my ability to make decent drawings, I made up and follow my own standards.  They're simple enough that any of our yahoo cadets can convert them to company standards. 

Also, I always draft and plot by lineweight.  No plot files needed.  That seems so easy, why don't more people do this?

When I hear standards I think of two types

1.  The standards on the CAD software layers text height or what not.

2.  The standards that the drawings call out. Or make part to or reference  SAE 4565 whatever

I think both are important.  An old man told me once that back in the days of hand drawings each hand drawn drawing had character.  Each drafter followed drafting guidelines but they all had small difference on how the letters were made and how the drawing had some unique characteristics of who ever made it.

I think having all of thees standards are good but one does depart from the character of the designer with over powering standards.

I would have liked to have selected 2,3, and 4.

Same here.  I was expecting an "All of the above" option until I saw "What are CAD Standards?" :)

Easy to follow, well written standards almost serve as a "How To CAD" manual for new hires and contractors.  If everything falls into place, it makes each phase of modifying / creating a drawing go so much easier, faster and with fewer questions, surprises and headaches.
It all stems from having well written standards and supporting documents.

I agree with what most have said. The real benefit is consistency which helps training, job sharing, "look & feel" etc.
Along with this consistency comes the ability as Keith mentioned to automate much of that process. You have to have a system
to automate to make it go much easier.

The hard part that I had as a CADD manager was trying to make drafters/designers/architects/engineers understand that the drawings we create are living documents (well most of us). With the increased interest with BIM or electronic facilities management software, our 2D or 3D drawings are now being migrated into these new technologies. These drawings are then being used to manage the structure etc.  Most will argue, "I don't get paid to do that, I need to get this drawing out in 10 minutes!" I can't argue with that point, but if you work at a "Full Service" A/E firm, wouldn't you think that would be something you could offer clients.  Some will argue it's not a A/E responsibility to provide this benefit with a set of deliverable drawings, but many contract's do depict the drawings follow a set CADD standard and a set of drawings at the end of the project. Again it all depends what industry you are in.


Back in the day, many drawings were translated and if you wanted to see a mess, don't have any consistency or CADD standards to your drawings and try to do a batch conversion... Now it's migrating to BIM models, of CAFM software.

There are good reasons to not draw all objects on layer 0 with color set to 1....

I'm in the long drawn out process of creating them for myself, as I'm the only one here who uses cad to any real depth. As for the poll that I missed some months ago, I feel they're important for most lines of work in this industry. They help when it comes to programming, using paperspace and probably a plethora of other things that I can't think of right now.
