Water? What Water?

Has water line design simply been forgotten about in C3D?
Drawing polylines seems to be the only solution. There are so many “canned” pipe materials for PVC within C3D, but those are for sewer systems. Take a look at this example:

It shows a HELP search for “sewer.” Notice what is found. Rules, networks, profile views, etc…
The next example is of a search for “water.” Again notice what is found:

Water Drops, & Watersheds, but no water line design tools!

Why?
Is it because it is way too simple? Or there is not a need to include it in your design?
I don’t think so. With agencies requesting minimum depths, separations, and even profile views to ensure these requirements are met, it is absolutely necessary to be included, dynamically, in our models.

But how do we achieve this?
Using polylines can be useful in horizontal locations; it becomes visible and can be utilized for noticing separation conflicts. Also alignments can be created using these polylines and then a vertical design can be utilized as profiles can be created. After that you still have no “pipes” or “networks” to apply revisions too all at once. Or if you needed the water line to be shown as a crossing pipe in your sewer profile. Or if you needed to label it?? What! Why would you ever want to label it? Labeling your polyline will give you length from beginning to end, but maybe you want this length to be measured from valve to valve. Well guess what? The model has no idea that there is a valve anywhere at all, as it is probably a simple block for visual representation proposes only. These labels are not dynamic either, meaning, if the line needs to be extended, the label has to be revised manually. :(

After all that venting, I can make a couple of suggestions.

Make one or more styles for your water line design labels. These styles should be alignment driven not by the polyline. This can read 3D lengths and will update when revised. Keep in mind the waterline is not dynamic but the alignment is. These label styles will only be using the 3D length of the alignment everything else remains non-dynamic, such as size and material. These labels should be on a layer all there own as you would a sewer pipe label. Text styles of these should all ways be associative. For fire hydrants, bends or valves, these will be non-dynamic as well, unless you have a block label reading the name and consecutive numbering of the block, but that is another Blog altogether.

A cool routine comes to mind when I discuss water design. It’s relatively simple to use, and creates more information than a List or Properties.
How much 6”? How much 8”?
1. First make sure all water pipes that are 6” are on the same layer (like C-WATER-PIPE-6”), and the same for 8”.
2. Then Using Map Explorer go to Topologies, Create New.
3. Create a new Network Topology named 6” Water. Notice that you can select: each line, all lines, or simply the layer that you created in the first step.
Once finished, your water line topology has a mass of information useful in any cost analysis or application for permit.
4. Now you can expand Topologies to view your created “6” Water” topology. Right clicking on this will give you several options, like showing geometry to verify what you’ve created, and statistics for things like number of nodes, links, and total lengths.
5. Repeat steps for your 8” lines.

3GB Windows Switch

As you have already noticed, some of our 3D models are getting larger in file size. Trying to rebuild surfaces using corridors made up of intersections and cul-de-sacs, our virtual memory sometimes seems non-existent. Complicated surfaces are not the only things difficult to compute, running large sheet sets using multiple drawings, often takes hours. Not to mention the Internet, media player, and outlook, that are running in the background constantly.
I'm not IT so I can't explain why running systems with more power is better, so you're just going to have to trust me on this one.


An explaination from our friends at Microsoft.
http://support.microsoft.com/default.aspx?scid=kb;en-us;833721
It is also explained by Autodesk.

I've also seen this blogged several times, so it seems to work pretty well.

What do you need to do?
1. OPEN - System Properties
2. OPEN - Advanced
3. OPEN - Startup and Recovery Settings
4. EDIT - System Startup
5. This will bring up a note pad file which you need to edit.
Replace...
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
With...
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional 3GB" /3GB /noexecute=optin /fastdetect
6. SAVE
7. Restart. Notice Windows will now open using more RAM!! Wicked Cool!! If you choose to, you can leave both the default and the 3GB, and Windows will prompt you for the type you would like to open.

I just read the “How to Blog” article from the Dumb Little Man website; I found it very informative. It discusses items like scheduling, topics, keywords, grammar, and honesty. It started me thinking of how to maintain some form of credibility while simply passing on information, and how it could be a little difficult at first.
I have never been a writer, and I have really never been very technical. I have so many visions of what I should be writing. I’m finding it hard to narrow the thoughts down. As I type, my mind wonders away into something much more interesting than a white screen with black text. Keeping in mind, difficult reading is never appealing, even to engineers. We love highly concentrated subjects and in-depth descriptions, in order to visualize, analyze, and conclude our own theories. Suggestions of procedures and tips to heighten experiences are really all I’m after.

My goal is to find the most motivating and simply “cool” routines or commands with the quickest results to make the average user intrigued enough to maybe someday strive to be a power user. Overcoming challenging tasks and demanding precise output is exactly what C3D was designed for, so it’s our job to make it the seemingly impossible, possible, with simplicity in our methodology. I have often found “crashing” or C3D disappearing from the screen altogether is a result of corrupt design. So being aware of this often changes the way we move forward. It’s necessary, now more than ever, for us to start our designs with precision and accuracy in order for us to meet the demand of precise model results and accurate plans for construction. “Garbage-In = Garbage-out”.

Welcome

As I start my first blog I wonder what, if anything, does the reader want to read. Should I be so selfish to only write what I want or need?

Sure why not.
I've come to conclusion if anyone should read, and comprehend, we can move on from there.

I want this to be my information outlet for all things CAD, focusing on C3D. Along with tips, and tricks I've collected while "monkeying around". Currently, all I've got is a lot of random thoughts of processes and procedures, ways I have done things in the past, ways I want things to be done in the future. All that stuff is just dancing around in my head looking for a way out, if only to be replaced with more developing ideas. I will post any and everything I deem as worthy material. So feel free to suggest subjects and themes.
