AutoCAD Civil 3D :: Create Expression That Returns Inner Pipe Diameter

Jul 16, 2013

I would like to create an expression that returns the inner pipe diameter if the pipe is circular, and the inner height and width dimensions if the pipe section is square or elliptical.  I tried this in the expression editor:

{Inner Pipe Diameter}|{Inner Pipe Height}&{Inner Pipe Width}

but it returned ? in the label .

AutoCAD Civil 3D :: Pipe Diameter In Profile View

Feb 4, 2013

As it stands, if you view a pipe network in a profile view with no vertical exaggeration, you expect to see what is essentially an accurate long section in all directions.  However, rather than being applied perpendicularly from the center line (or arguably the invert), diameter is applied strictly vertically.

Now, this made sense in the days of hand drafting when it was far easier in a vertically exaggerated profile view to simply measure the dimension vertically rather than determining how the exaggeration affects the perpendicular distance.  But with the computer doing the measurements, is this really a problem anymore?  I've debated that to some degree it's strange to consider that the crown of the pipe may be at a (slightly) different station than the invert, but this is simply fact in the field.  And I've also thought that it's nice to be able simply measure vertically in an exaggerated profile, but I can't remember the last time I dug my scale out of the drawer.

All the theory aside, the real problem appears when you try to profile a vertical, or even a near-vertical, pipe.  The fact that the diameter is applied vertically means that the vertical centerline is shifted the length of the pipe radius downward and upward.  In other words, rather than seeing the invert and crown of the pipe, you just see one line, though it's really two lines on top of each other.

I wrote this off for the last 4 years of basic Pipe Networks because I acknowledge that storm/sanitary outside the building is rarely designed vertically, but with 2013's release of the Pressure Pipe Network, I really expected Autodesk to change the way the profile views represented pipes.

AutoCAD Civil 3D :: Show Inner Pipe Or Headwall Base Width In Table With Expression

Mar 6, 2013

I am trying to work out a way to set up my Structure Table so that I can show either the Inner Pipe Width OR Headwall Base Width to avoid having Question Marks showing in my Table? Is there a Function in the expressions that equates to a Non-Existent or Null Parameter. Ie.

IF({Inner Structure Width}=???,{Headwall Base Width})

Also, Is there a way to hide Structures from a Table, in particulat, Null Structures?

Currently using Civil 3D 2013 & 2014 SP1

AutoCAD Civil 3D :: Pipe Between Structures Only Has Location / Diameter Snaps?

Jun 14, 2013

So I have a proposed storm sewer pipe network and 90% of pipes snap to the structures fine, with a start/lengthen snap on one end and an end/lengthen on the other, and a location/pipe diameter one in the middle. When I go to draw one of the pipes though, I draw structure to structure and it doesn't sit properly. I click on it to make sure it snapped to the structure but there is no start, end, or lengthen snaps on either end of the pipe. Only a Location/Pipe Diameter one in the middle. Therefore, I cannot manipulate it's length or where it connects, I can only move it around from the center.

AutoCAD Civil 3D :: Create Expression In SAC

Feb 2, 2012

I am trying to create an expression in SAC and am having trouble getting it to work the way I want.  The goal is to have the subassembly figure out what slope to use.  If I do not have super elevation, I want it to use the grade for the in the input.output parameters.  If I do have super elevation, I want it to use the super settings.  So far I have this


This works if I am only creating a left side.  However, I want it to decide which side super elevation settings by the input parameter side.

AutoCAD Map 3D :: Creating Annotation For Pipe Diameter On Water Main Atlas

Mar 28, 2013

I'm creating Annotation for pipe diameter on a water main atlas.  I have spans of pipe that are 50-200 feet in length. I often don't want the Annotation for pipe size to be placed at the midpoint of the line segment.  I'd prefer it to be placed at the location where I 'select' on the feature. It seems like .LAGELPT, .CENTER, AND .CENTROID all place Anno at the midpoint of the line.  X1,Y1 places Anno at the start of the line.  X2,Y2 places Anno at the end of the line.

Is there an Expression String or Property I couldspecify, that would place the Annotation at the point where the feature was selected on-screen?

I was wondering if you can create rules for a pressure pipe network similar to the rules that you can create for a pipe network.  I would like to create a cover and length rule for my system.  So far I saw that you can set a cover before drawing out the pressure network but I do not know how to edit that after the pressure pipes are drawn in.

AutoCAD Civil 3D :: Pressure Pipe - How To Create New Fittings And Add To Content Catalog

Apr 4, 2012

C3D 2013. I am trying to determine how do add additional content to the parts library.  

I have explored the Content Catalog Editor and have been able to add new pipe materials, but it appears that the only way that I can import a part is with a .CONTENT file.  Is there any documentation on how this file is supposed to be configured or created?  Is there any documentation on the Content Catalog Editor in general?  We need to be able to add new pipe, fittings, valves, appurtenances in order to make this new feature usable in a production environment.

AutoCAD Dynamic Blocks :: Make 1" Long / 1" Diameter Straight Pipe As A Block

I would like to make a 1" long, 1" diameter straight pipe as a block. I would like to insert that block into my drawing, say...on a 90 degree elbow. After inserting the straight stub, I would like to use a grip to "stretch" the pipe length to the next fitting. Ultimately, I would like to compile a parts list for my pipe drawing that will give me the straight pipe length. I've been doing some searching and 3d dynamic blocks seem to be impossible.

AutoCAD Civil 3D :: Depicting Both Slice And Cross Cut Pipe Profiles Of One Pipe

Jan 8, 2014

One of the things I seem to struggle with is being able to depict a single pipe when it needs to be shown in one profile as a crossing pipe, and another profile where you you show a lenghwise slice through the pipe.  I end up tracing the pipe with eliptical objects where I'm cutting across the pipe and setting up more for the lengthwise/sideview of the pipe.  Is there a way to have two different styles for the same pipe, one for a cross cut and one for a lengthwise slice?

AutoCAD Civil 3D :: How To Select A Profile Used In Expression

Mar 15, 2012

One of the main things I do is label elevations from an alignment and a profile, in plan view.

I have a style that does this, and it gets to the point where it asks to pick the profile.

If the profiles are data ref's, i can pick from a list, but if the alignment is xreffed, you must do a graphical pick.

This is super inconvenient, as my profile views are in a different base than my alignments, and they are way off to the side.

So I must xref the profile base in, and split my viws so I can pick them without excessive zooming.

Did Autodesk neglect the fact that if they make objects available via xref, they also need to make child objects available?

If I choose to use a dref as the data source, I must make a dref to the alignment and each profile I want available.

Three steps per street at a minimum.

This is also super inconvenient.

I'm struggling to find a decent workflow on this. Both approaches seem painful.

I had always thought the xreffed objects would provide the profiles, and only found they do not just now [URL]...
