AutoCAD Civil 3D :: Sidewalk Not Following Target Width Alignment?
Mar 26, 2012
I have a variable sidewalk width and would like my corridor to follow sidewalk as defined by Target Alignment for Sidewalk width (polyline). My sidewalk is merging at ends with roadway however my corridor feature lines presenting sidewalk is not following/merging with target. In all other locations, it follows the target width however where sidewalk merges with road, feature line goes straight.
Attached PDF should hopefully explain what I want to say. Could not attached dwg due to size issue.
I am using Basic Curb and Urban sidewalk assembly wherein my Blvd targets are set to 0 (none).
How can I make my corridor follow sidewalk width target exactly.
I am using C3D 2010 , Win 7 Pro.

I am trying to model a DOT project in a fashion that allows a corridor surface creation for not only the finished surface, but also the datum surface. This is a machine control project currently under construction. One of the DOT's typical sections includes a shoulder subassembly with a grade break in it. This particular assembly varies in width at the grade break. I would like to have the option for a target width alignment at the grade break.
See attached sketch.

if i want to target the existing surface beyond the edges of my road/sidewalk, should i use the link slope to surface subassembly at both ends? i want the model to test if in a cut or fill situation, and then target.

Let's say I have an assembly called Original, as shown below with a 6m wide lane. Now I want to target it to 8m wide for some road widening. Now, will it stretch along the slope of the subassembly (Case 1) until 8m width, or will it just shift laterally to 8m (Case 2)?
I know that we can set the default slope of it, but I'm not sure if it gets overriden due to the Target-width process.

Am struggling to pull off some corridor but the standard daylight subassembly is letting me down. It mulfunctions when I connect it to the Generic Linktoslope subassembly. In some Areas it works fine but in others it doesn't. My plan is to apply a ditch at the point where the LinktoSlope meets the ground level and to have this ditch again daylight back to the target surface.

This is my first corridor and I've been slowly working my way through it, but just seem to be running into problems left and right. My latest problem is the following;
I have my Corridor's Subassembly Daylighting set to target my Left side 33' R/W offset alignment. For 90% of my alignment everything is working fine or at least appears to, but I have 3 different areas where the Corridor refuses to daylight from the bottom of the 1' ditch out to said left alignment target even though the ditch is well below existing grade. I've attached 2 screen grabs.

We have just started using Civil 3D. I need to be able to create an assembly that will place a sidewalk at varying offsets (it is too random to make seperate assemblies). I have tried making an alignment of the back of the walk and attempted to use targets in the corridor to achieve this .
I will attempt to attach the DWG that I am working on. The Main alignment is PR-1 as is the corridor and the alignment that i need the back of the walk to follow is PR-1 BWR.

i've made a serpantine curve that starts from one line of alignment and end on the other line.
i wanted to know how can c change alignment direction when these two feature line and alignment meet each other in order to change the alignment path?

I using a data reference/shortcut to properly label an alignment in paperspace. However when I reference the alignment in and apply the labels the aren't the same as the original alignment that I am referencing. Is there a setting where I am supposed to apply a new beginning station.
Also it seems as though the stationing(distance) isn't even matching up 1:1 with the original drawing. For example in the original base drawing my alignment starts at 10+00 with the next PI at 14+76.98, but the stationing on the reference alignment starts at 0+83.33 with the very same PI being labeled as 1+23.08. So the very same distance is 476.98' in the real design and the drawing it's being referenced in, but the stationing of the referenced alignment shows it as 39.75 Units.
I've attached a screen of the beginning of the alignment.

Using Civil 3d2012, Is it possible to change the alignment label style set after the alignment has been created? For example, for an alignment that was created with alignment label set X - change the label set to alignment label set Y? It seems like this should be pretty easy, I must be missing something obvious.

I have a question on Alignment PI's. (Point of Inflection/Intersection)I have an alignment where some PI's have curves, others are merely hard bends.
Is there a way to automatically label the PI's even if they have an associated curve? (I'd like PI, PC and PT)Alternatively, can I only show markers at PI's without curves?

I'm trying to edit some existing alignments. When I create new entities, they do not show up in the alignment grid view. Why is this?

Launching alignment grid view/alignment entities,
I’m wondering if there is a way to launch alignment grid view/alignment entities (attached) without the need to first launching “alignment”? This dialogue box is quite essential in editing the values of radius, degree of curvature and deflection angle for the selected curve.

Can I inherit the station from one alignment as the begin station for another alignment?
For example. Alignment 1 is 1000 ft long and starts at sta 0+00.
At sta 8+01, Alignment 2 begins and goes off in another direction.
I manually enter 8+01 for begin station Alignment 2. Life is good. Still in the design stage, and customer needs to modify Alignment 1 to avoid something. Now Alignment 2 intersects Alignment 1 at sta 8+15, but same N/E coordinates.
I manually enter 8+15 for begin station Alignment 2.
It would be better if Alignment 2 could inherit the begin station based on the new stationing from Alignment 1.

Version 4.0.1.5601
I'm not in good command of the Xara model here. If I create a move a series of copies lines (in effort to, say, make a grid), if I move the line from the bottom upwards it tends to align on the top edge. If I move from the above downwards, it tends to align on the bottom edge.
However, not always. <----this spooks me a bit.
This is with "align to grid" on, but "align to object" off.
Is there a way to have the line path itself (the infinitely thin middle of the line) align to the grid? I'm assuming that I can then worry about line joins (mitre, butt, etc.) separately.

I am using OffsetTaget.isValid in my subassembly.But i realize that when i put this formula it checks the whole drawing for that target and if the target polyline exist even a piece of polyline in the drawing then C3D considers it for all sample lines.Is ıt possible to be able to check each single sample line if it is going to intersect that target polyline or not?

i have just spent 8 hours today trying to find a link that will vary target a poly line that i have set. i cant seem to find the link that will do what i need as per the attachemnt. the section between the edge of the foot path and the start of the fill/cut slope needs to be variable
i know how to set all the targets but this link seems to be a fixed length.

I want to programmatically assign Targets to subassembly of baseline Regions but I could not Success in that here it is the code
Corridor corridor = ts.GetObject(icor.ObjectId, OpenMode.ForWrite) as Corridor; foreach (Baseline b in corridor.Baselines) { al = ts.GetObject(b.AlignmentId, OpenMode.ForWrite) as Alignment; foreach (BaselineRegion br in b.BaselineRegions) { double st = [code]........

What i want to do is ; i have a corridor with both right/left sides ending with linktosurface with fixed slope.In some sections my existing surface is not wide enough to get intersection with link to surface with fixed slope. So i want to use this "conditional horizontal target " if my surface is not enough wide for intersection then just intersect or go to the edge of my existing surface. But i learned that surfaces cannot be used as an offset target with that subassembly.

I created a custom assembly that has an offset target. Is it possible to program my subassembly to target only on the side of my subassembly (and not criss-cross onto itself it the target is on the other side)?

In particular, I am attempting the infamous task of creating driveway openings using a horizontal target with my sub-assemblies. I referred to the AU 2010 video tutorial that gets passed around here on the boards, and for the most part, it works with ONE tiny exception.
Like in the AU video, I set my conditional target to look for a particular layer, and I first attempted the exercise by placing ONE polyline (i.e. driveway opening) on the layer, and set set conditional "found" and "not found" targets to find this pline. The target found the pline on the layer on the right side of the road where I drew it, and created the opening as hoped, but it created an opening on the LEFT side of the road as well!
What do I have to do to prevent the conditional horizontal targets from ignoring the exact opposite side of the road? In my assembly, the left conditions are set to LEFT, and the right conditions are set to RIGHT, but when the corridor gets modeled, BOTH sides of the road will show an opening even if there is only one pline drawn.

I can import my SA fine, but the problem is that the top of it needs to be cut off 1 m above the existing ground (which is already a surface in civil 3d). How do I setup the target surface so that when I import the SA into my drawing, I can link it to that surface and have it cut off 1 m above the surface?

I have just installed Civil 3D 2012.
For all previous versions I was able to change the default Profile <<C3D_Metric>> in the Shortcut Target to my custom Profile with no load errors.
When I do this in 2012, I receive a rash of errors upon load(see below), wich results in an incomplete program.

how to create corridor, and I have a question about assembly elevation targets.
When creating a corridor, the profile is required as dependent object, which gives the elevation of the centerline of the road. Based on the definition of assembly, the elevation of the corridor at the offset targets can be determined by the profile. My question is if the assembly elevation target specifies the elevation at the offset target too? If so, why both profile and assembly elevation target are required?

I've to make a tunnel on my project. I get some subassembly on web but all the tunnel subassemblies have the target point on Width or Offset Target and Slop or Elevation Target. I don't know whats happens but only my region that owns the tunnel subassembly isn't recognizing on corridor, and isn't drawing on my sections too.

I created an assembly with a broken back subassembly. I moved it to a 40cm horizontal offset away from the axis. I attached it to a corridor using two polylines as targets. One for the broken back and one for the outside lane. In civil 2011 everything works fine.
In civil 2012 the ETW is offseted by the same value i moved the subassembly away from the axis! If i change the subassembly offset to eg 1m then when rebuilding corridor the ETW moves to 1m away from the target polyline!
Same strange behavior using subassembly R2011 or R2012.
See the attached dwg.

I imported Google earth surface (at eye alt 600m) to civil 3d 2012 and created an alignment of length 181m.
When I exported same alignment to Google earth , it showed the length as 190m ( the difference increases with increase in length of alignment) And also the profile view of the alignment in the Civil D & Google earth varies.
