AutoCAD Civil 3D :: Feature Line Flow Arrow Direction Expression
Apr 4, 2013
Now, in my understanding, the flow arrow should either be rotated 0, or 180 (pi radians). But clearly, some of them like to have their own mind about things, and decide on some other rotation. It seems that on the steep slopes, the arrows go a bit skew.
I think the skew is related to the actual elevation difference of the segment, rather than the steepness of the slope. A long segment with 15% slope has a worse skew than a short segment at over 30%, presumably because the elevation difference from the start to the end of the segment is larger.
I can't seem to find where to increase the flow direction arrow size on a watershed. Am accessing remotely, it's a bit laggy and bothersome, but doable. I looked all over Toolspace.

when I draw a polyline, or use it as the linetype in a feature line style, the arrows seem to revrse whenever there is a change in direction any significance. Also, the reverse command and reversefeature command have no effect. Rotating a segment does not change the direction. I know I must be missing something.
In the attached, I have a feature line, and a polyline that the arrows change direction when the feature does.

I can't figure out how to reverse the flow direction on my pipe so I was going to just redraw it but after I delete a pipe and rt click to edit network the "add pipes and stuctures" won't let me add anything. I'm just guessing I need to reverse the flow direction because my invert out and invert in elevations are backwards in the profile. I'm working in Civil3D 2012.
I am trying to create a new linetype using arrows to show the direction of a flow. I can get the outline of my arrow head to save as a shape, but have not figured out how to save the hatching to show up in a linetype. I need the arrow head to be shaded in solid. Also is there any downloadable linetypes out there for Civil 3D?
I am looking for a Line Label Style Expression which will perform a rounding function on distance labels that display my "General Segment Length" value.
What I need is to be able to remove "Trailing Zeros" from my distance values, so that if precision is set to say 0.01 and my distance value is measured as 45.5, I do not get 45.50 but 45.5.
I've got GIS shape files for sanitary sewer pipes and manholes which contains object data for the upstream and downstream inverts on each pipe as well as the lowest invert at each manhole. Ideally, I would like to add an arrow to the pipe showing the flow direction in the sewer. i know I can use the annotation template to label the inverts, but is there a way to automate the process to add the direction arrow?
I have made line types with text and need to reverse the direction that the text reads. The text autocorrects based on UCS north. The UCS in the drawing is rotated 90 degrees so line text reads upside down. I type in the reverse command but the text does not change.
I drew in a water line that had an arc in it, the "W" symbol in the line (or arc rather) is upside down. i've tried the reverse command, tried re drawing the arc both ways, tried re loading line types, is there any way to fix this?
I needed to remove a feature line that I used as a break line when creating a surface. When I removed the feature line from the definition of the surface, the grading did not change. It appears the points created by the feature line remain which is why grading didn't change. The only work around was to delete these points.
I noticed the same thing happens when I removed the surface boundary and inserted a new boundary. why these points remain and how to remove when I delete boundary and feature line from surface?
I have created a linetype with the text GAS OPTION in it. The line is continuous with a break around the text. In a straight line the linetype works fine (breaks around the text etc). However, when I use a polyline and spline the line for a curved line the text aligns with the direction of the line at the start, but when the line bends, the text suddenly changes direction and reads in the opposite direction. It looks like AutoCAD is trying to keep the text upright rather than following the direction of the line. When the text changes direction it also changes its insertion point and overlaps the continuous part of the line. I have 2013 AutoCAD.
Here is the string I used for the linetype.

I have a special ditch profile that I'd like to use a linetype with arrows on. Currently, it shows the arrows going up station with my mainline profile. i.e. now water does flow uphill...
I need the features shown in a connected SHP file to display an arrow indicating their direction (i.e. -----> or ----->-----). This seem that it would be important to anyone using Map for municipal engineering (sewers tend to be directional!), drainage (so are culverts!), etc..The difficulty in doing this simple task is just adding to my hatred of Map (especially given the amount of money I've spent on Autodesk products)!
I have a path with a smooth point. The two direction points form a direction line with any non-45-degree-angle - say 11.8 degrees. I want to drag one direction point while keeping the angle of exactly 11.8 degrees.
I have cut several sections at different points along a road alignment. The sections are cut facing the same direction as the alignmnet. Is there a way to reverse the section direction without changing the alignment direction?
Is there any way to project feature lines into a profile when the plan view is xref'd? I have my plan view "existing topo" with all existing features/Figures and a existing surface.
My profile is a separate dwg with plan view xref'd and surface a data shortcut. Of course there are feature lines and Survey Figures in the existing top I want to project into the profile, but can't because it is an xref. Besides copying .
C3D 2012. I am trying to get the distance from the start of a featrue line to a selected point. My object is "FLobj" and my Point is PT1. I am using the method Get2dDistanceAtPoint. This is the line of code.
I am wanting to add the name of my feature line to a label style. I am trying to create a label style that will show Lot Number and Area. I know i can create parcels, but i dont want to! I have also created a map table that can do exactly what i want on polylines, but will not work on an xref. Labelling featurelines does work in xrefs.
I am building a surface and have back of curb, curb face, and curb flowline going around a curve. I cannot create the lines with the usual pline as they will cross due to poor field collect. I created the curbs with multiple arcs. I was then going to change them into Feature Lines and am wondering if I can then use them as breaklines in a surface.
We have cooridors with features such as terrace drains and flowlines, but we cant seem to get the linetypes to show up correctly. For example a flow line should have arrows but it shows up without the linetype and looks continuous.
I am building a corridor with the right side of the pavement fitting to the existing surface.The subassembly used to link the edge of pavement to the existing ground is LinkSlopeToSurface.
On the corridor created, the feature line (code P2) of the corridor surface (top) starts from the station 0+025, instead of 0+000.
I was wondering why there is no feature line P2 for station range 0+000 to 0+025? Does that mean the linkage to the existing ground surface not exist for the slope defined in the subassembly?
