BOM Weight

This little change is a fun one. It's not exactly for the faint of heart I guess, but it's not THAT painful either. In CADWorx Plant, you can add weight to your BOM. The great thing about this is that you also get a TOTAL BOM Weight. The downside to this, and anyone who's put out a Weight on a BOM will understand this, the weight that is figured off of a drawing is WRONG. Nothing against the way we do weight, but there are a lot of variables that aren't taken into account, coating, weld (in some cases), shipping flanges, etc... It's a universal habit to take the weight we come up with and add 10%. In CADWorx Plant, although we can't do this, we can append what the BOM says to indicate that the end user should add 10%. Think of it as covering your tail. The steps are easy, but you have to modify a file that COADE prb doesn't want you too, but that's okay :)

In the support directory, under your instal of CADWorx Plant (or Plant Professional) You'll find a file called English.dic. Open this file up with Notepad and do a FIND on T0097 . This will take you to a line of text that looks like this:

T0097=TOTAL WEIGHT: %.2f

This is the line of text that get's appended to bottom of a BOM when you add weight as one of the columns. The %.2f tells the software to append the total weight, to 2 decimal places. Let's change that line to read:

T0097=TOTAL ESTIMATED WEIGHT +/- 10 PERCENT: %.2f

Now, save the file, restart CADWorx Plant and run a Bill of Materials with the weight column in there.

You'll notice that right there in the BOM is your text.

New Sizes

So, you have gotten into CADWorx Plant, or even CADWorx P&ID, everything is going great, until you get to a REALLY big OD of pipe. As a default, CADWorx has sizes from 1/8th of an inch, to 64" on the Imperial measurements. This SHOULD cover about everything, but as a good friend of mine in California pointed out today, sometimes that's just not enough. He had to do a 90" Elbow. Now, some of the really cool things that we did with the elbow, will be the subject for another day, but for today, let's talk about how we get 90" into our software.


There are 2 things that you need to do, the first, and easiest is really almost the most intimidating. Just like in the BOM change we did, we are going to have to "tweak" the software.



In the install directory of CADWorx Plant (or P&ID for that matter) is a folder called system. In there, we are going to open up the file called setsize.tbl . This file is where CADWorx pulls the size numbers for the size dialog box that we see in the software.


Let's break for a second, and really look this thing over. This is complete, I mean, complete on the size range. 1/8th inch to 64" inch is a pretty good spread, but when was the last time you used some of the sizes? Don't need them? No problem, delete them. Some companies may want to reduce the AVAILABLE size here, as well as limit through the spec.
Now, back to where we were, let's scroll to the bottom of the list and add in our 90" numbers. Yea, that's it. Save the file, and when you re-open CADWorx, those numbers that you added (or deleted) are there (or gone).


Once that's done, it's now just a matter of updating your data files to have the dimensional data needed to place a component to your new size.


There, that wasn't TOO painful was it?


There are 3 of these files, setsize.tbl for imperial, setsizeM.tbl for metric, and setsizeA.tbl for mixed metric.


Hope this helps, and if it sounds any at all confusing, please, let me know.
