AutoCAD Civil 3D :: Bolted Manhole Rims And Closed Tank?
Dec 27, 2012
I had a chance to use the old StormNet software extensively in my previous company. This is my first time that I'm using it under AutoDesk. It appears to work similarly. So now I'm trying to model a small but a bit of a complex system.
I have a modeling scenario where I have a storage tank with two orifices. The first orifice outlets to a 10 inch diameter pipe which eventually outfalls into a stormwater treatment area. This area will allow ponding. Due to site topography a portion of this pipe run will be pressurized with the outlet set just low enough below the 1st orifice elevation at the tank. The second orifice outlets to a 12 inch diameter pipe which connects to the underground storm drain system via gravity. This second pipe run will only take on water that exceeds the capacity of the first. With this scenario I have a few questions:
1. In trying to model the bolted rims to make the portion of the system to work as a pressurized system, my understanding is that I have to set the surcharge elevation (at the junction) high enough above the max rim elevation. I have set up the surcharge elevation high enough, trying different elevations and the max water elevation in all cases is exceeding the max rim elevation.
2. My storage tank is a close tank. Is there a way to ensure that is modeled as such or does the program assume is a storage node such as a detention pond?
I have a sanitary run manhole to manhole with null structures in between for lats. Each null is named "wye(lot#)" which I really do not need labeled anywhere but grants me the illusion of order and control. When I label the manhole (style uses text for each component) it references the inverts as from adjacent structure the nearest of which is the null. I need it to reference the upstream manhole as the from structure. BMP?
Another issue is the text for each component. There are times when I need to have the manhole label show "INV 8" IN 209.50 Int Drop (MH110)" or "INV 8" IN 208.75 w/ Slide (MH 108)". But as you know if I add to one I add to all. I found a post that discussed editing the xml to do this but my code either looked different than the example or I was looking at it cross eyed. I think if I could add an invert type column to the structure properties pipes tab the text for each component could add it to the label.Is there a better way people have been handling this?
I have a civil3d pipe network that has modeled by my co-worker before.
Now I want to put that pipe network on new surface and get rim elevation from surface automatically and also after stretch it can update rim elv based on that surface.
I have my design drawing referenced into another drawing for plan and profile sheets. I made some changes to my pipe network in my design drawing, and my manhole profile labels disappeared in my sheet drawing!
The manhole labels in plan view stayed where they were, and updated with the changes I made. The profile labels just disappeared.
problem labelling manholes when using the 2013 ukie template? - pipe labels show up but nothing else.
If I open the label style composer it looks fine in preview, visibility is set to true and its on the same layer as the pipe labels so should display OK. It seems to be a template setting though because if I open the metric or imperial templates and draw a network the labels all work. if I can find the right tick box it would be quicker than labelling with mtext.
I remember seeing an article or web cast on how to create a style to display a single line for a manhole. It may have been about using the parts create tool. But for the life of me, I can’t remember where I saw it.
Also I had created a style in C3D2007 to display the pipes in profile as a single line. This was done by drawing the flow arrow in a non printable colour over the top of the pipe.In C3D2008 this is no longer possible. So now what?
I have a label style creating a callout bubble for structures in a pipe network, but it keeps placing the label (and therefore, the leader when dragged) at the edge of the structure, and I want it to go to the center.
I created pipe network for my storm drain project. I have located all the structures (manhole) to all angle point of my alignment as required. Also I "insert" manhole every 400' per local code requirements using the command "network layout tools; structures only. My problem is I couldn't find the tools how to trim the pipe that pass through the manhole. Please see attached pdf file.
I have used PEDIT to join multiple polylines, which now appear as polylines. But when I use QSELECT to show all open (non-closed) section, one polyline still shows up as open.
I've attached the file I'm working on. The polyline in question is the green outline on the object on the right.
I have been trying to draw a precast concrete tank and have run into a problem. The tank walls are not constant thickness. At the bottom they are 3.5" thick and taper to 3" thick at the top. Also, the top dimensions of the tank are longer and wider than the bottom dimensions of the tank. My solution has been to draw the outside bottom as a rectangle and offset the rectangle by 3.5". Then repeat this for the top dimensions, set the top two rectangles at the correct elevation and loft them. Then, I press-pull the center out of the tank. This results in a quasi-correct representation of the outside tank but the wall thickness does not taper correctly and the walls are hollow.
I have been able to draw the precast concrete tanks I needed. I drew several models and saved them as WBLOCKS to insert in new drawings. The problem is that I don't seem to be able to select a particular face of the tank upon which I want to align the UCS. What am I missing with regard to blocks and UCS alignment?
i am getting a message when i click on something from my tool palette saying that it does not display when it is docked and closed. how do i undo this so i can use objects from the tool palette. how do i "unlock" it?
I often use feature lines for parking lots and ponds. They're great when they work, but they drive me NUTS when they don't - which is a lot of the time. For parking lots and ponds, my feature lines usually close back on themselves. That's when I have trouble breaking the feature line. When I use BREAKFEATURE, I choose two points and this should, in theory, leave a gap in the feature line between those two points. That's not what happens. I end up with a huge gap between the first point I picked and a vertex point 5 or 6 vertices away. It doesn't matter where I pick the breaking points.
I've also tried TRIMFEATURES. I draw lines across the feature line where I would have chosen the breaking points. But the portion that I want to remove is the portion that always remains. It doesn't matter where I select the feature line to be trimmed (inside or outside of the cutting edges).
I think there may something wrong with the feature line itself. Sometimes, if I erase the original and draw a new one, it will trim just fine. But that's such a headache, and it doesn't always work. If I knew what was causing the feature lines to go squirrely, I would aviod it. Unfortunately, it seems like breathing the wrong way can screw up a feature line.
Is there a way to use the Split Solid tool to partially split a circle and have multiple solids after.
Ex) I would like to cut the tank at the 180 and 270 deg marks. Using the split tool still cuts through 0 and 90. I tried drawing a line from a top view that started from center going through 180, but it still goes through 0 as well.
I've attached an example shell of where I would like to have 6 solids after.
I always get the message after I make a closed boundary polygon, and I know it's a closed boundary, but I know how to fix it. It just bugs me sometimes when the message pops up when I add it as a boundary under the definition of a surface.
I've read 2013 is going to include line labeling capabilities by selecting 2 points rather than selecting linework. Is there going to be a way to label an area without creating a closed polyline or parcel, where it works the way a hatch works. So if I selecting in the middle of multiple individual intersecting lines, it labels the area.
I am trying to create a closed loop alignment for a track. Previously i have included a small gap between two alignments to get around the problem when a housing plot is created (see the attached dicument) when a closed alignment is created, Is there any way of getting rid of this?
I have modeled a tank(storage) and i need to show some of the piping that is inside the tank. I tried removing some faces and extruding the edges, then some beveling, to show some thickness but that really messes up the smoothing around the hole. Is there a better way to do this to maintain the smoothness?
I have a .psd picture of a tank and try to animate it in AE by rotating its wheels and tread (or track?). The only solution i have come up with is to slightly change tread layer's x and y positions in every frame, making it to vibrate. However it does not create rotation illusion which i'm after - the tread vibrates, but doeas not revolves around the wheels. If there are other solutions to make tread layer rotate around tank's wheels, i would be glad to hear about them. All 7 tank's wheels are separate layers and the tread layer is above them. The rest of the tank's layer is above tread layer
