AutoCAD Civil 3D :: Point Groups Elevations
Feb 28, 2013
I have two different point groups that I am using in my drawing. One is from a survey done a few years ago and the other is from one that I did just the other day.
I don't have a problem inserting the points or whatnot, but the issue I am having is that when I click "Datum" to adjust the elevations of my new point group (to make my benchmark 100.00'), Civil 3D alters all of my points; including the ones from the older survey. Is a way to adjust elevations to only one set of points.

I just discovered survey figure groups and am playing around with them. Great way to bring certain figures in & out. What seems crazy is that I have to check them on/off one at a time. Am I missing something or is this the only way to add figures to a figure group?

How to set a default point style for point groups? Whenever I import survey points, I always put them into their own point group, so I can display each day's worth of survey data differently. For some reason, the point style always defaults to a certain style (our control point symbol). I'd like it to default to Basic, so I don't have to change this every time. Is it a template drawing setting somewhere?

Sounds simple enough, but how would I subtract 2.300 from every point elevation?

Can you create point groups in your template to be used by all drawings or do they have to be per dwg.?

Is there a way to have multiple elvations on a single point?
Such as with a top & bottom of curb.
I have tried to add a component to the style, assign the name as the control, and put in the elevation
I want, but you can't have multiple points with the same name.

For some reason I have three copies of my point groups. I have not inserted any drawings into my current drawing. Just been working with pipe networks. There are three copies of every point group even though only a couple of point groups are being used in this drawing if that matters.

I have about 50 point groups that the client needs in an ENZ format, is it possible to export them all at once with the name of the point group being the name of the file?
if so, the more annoying part of this is that I actually have to make the ENZ file an ENZD file with the D being the name of the file for each point, if both of these things are possible

Inclusion of “point groups” in a table, I wanted to include “point groups” in a table but couldn’t know what is the most appropriate command to accomplish this task.
I tried the “extract data” command (attached) but sounds not to produce the required table.

We have conducted a 6" x 6" grid survey of a building's finished floor and the client has requested the output drawing of the point file survey to be shown in Millimeters. The Point Label style in Civil 3D 2009 only has the option to show Meters which isnt precise enough for the clients wants. I am using the metric template in autocad Civil 3D and all units are set to metric.
Is there a way to change you point label to show Millimeters?

I am running into a problem where Civil 3D is creating multiple point groups of my 4 existing groups (the original group names are Topo, Existing Ground, Hide, and All Points). The new groups seem to be copies of the originals in terms of styles but do not include the points that were designated in the originals (no points are assigned in these copies).
The groups appear some time after I create the surface.
I've also noticed that this occurs in my list of grading criteria as well.

write out the steps involved in importing one set of points to a point group so that it is one color and on one layer and a different set of points onto a different layer with a different color? We gather survey data using different methods and want to be able to overlay the data sets for quality control purposes and them being the same color is crazy making

I have created 8 points (from 4 locations with 2 depths in each location) in _All Points/Points. These 8 points are grouped into 2 Point Groups:
Points #1, #3, #5 & #7 for Point Group - (1) Depth#1 and
Points #2, #4, #6 & #8 for Point Group - (2) Depth#2.
The "Name" of Point is filled with the SampleID (like cdc-ss01-s1, cdc-ss01-s2,...) - see the attached file. From the HELP of AutoCAD C3D 2013, I have read/studies the "Point Tables" and "Point Label Styles" and I cannot figure out how to label the 8 points to show the "Point Number", "Point Elevation", and "Name" of Point (i. e. the SampleID like cdc-ss01-s1 & cdc-ss01-s2, ....).!!

I'd like to turn off the leader for individual points that have had a component dragged. For most points, I need the leader, but for others, it's just in the way. I'm beginning to think that I have to make a whole new label style in which the leader for dragged components is made invisible.

I'm working on a stream restoration project and we need to determine the x coordinates and corresponding elevations along a stream alignment at certain sample lines. The centerline of the stream's alignment has been created as well as sample lines for cross sections at 50' intervals. We need the coordinates & elevations of each sample line (cross section) exported into an excel/txt document.
For instance, at station 1+00 of the alignment we have a sample line. We need to know to the right and left along that sample line the corresponding elevations and that x coordinate) from the alignment. Primarily, whole contour intervals but more information would be useful as well. I was hoping this could be automatically generated.

I am trying to have a block scaled on import baised on the elevation of the point. I already use description key sets to scale blocks in import to parameters added to the code libary, for example; "Pole 0.31" draws a circle with a diameter of .31 meters.
Is there a way where I would be able to scale a block on import based on the elevation of the object? For example, a point's elevation is 1.7m, so on import it would scale a block by 1.7 on the x/y axis. Ideally if I were to modify the datum of the points the blocks would automatically scale, but that is more of a pipe dream.
We import the data from a trimble r8 rover and convert the file to a FBK file before importing the survey data.

C3D2012. We have a master C3D template that includes a number of point filters (let say 20 of them) and a number of layouts (again, let say 20 of them) to accommodate our two sheet sizes.
Here is the issue that I am running into, when the Plan Production tools use a layout to create plan and profile sheets from the same master template that is used to initially create the file, the whole process will duplicate each point group 150 times for every group (see attached). So, what I ended up with is 20 point groups X 150. In my example, I ended up with 3000 duplicate point groups.
The end result is a file that is somewhat unusable do to the number of point groups. The other issue is now that all of these point groups are in the file you are unable to delete them all at once without "crashing" C3D. So you are left to deleting a handful at time. It is also best if you turn UNDO off while you do it.
I have been able to duplicate this in multiple files; however, from the same master template. As a test I did create separate templates (which are pretty bare bones) for the plan production and all works well. Therefore, there is either an issue with C3D and Plan Production and point groups or it is our template.
I would really like to nail down (as best I can) what is generating the 150 duplicates/ point group name to see if there is a way "around" this.
Currently, I am unable to share the template, but it shouldn't be too difficult to re-create. Take any template, add some point groups to, add a plan and profile sheet to one of the layouts, create a new file from this template, finally create plan and profile sheets from the layout in the very same template.

Is there a way to create automatic Point Groups when importing points? Sort of like a Desc Key for layers? I know it probably is impossible but I have to ask.

In an effort to firm up my understanding of how styles, point groups, description keys and layers collide, I followed the recommendations of an article. How groups/deskeys function together for layer visibility.
This process of Layer visibility that is supposed to make the program flexible makes it almost impossibly complicated.

. How to assign proposed elevation to layout alignment along each station?. I know there is a way in LDT to assign proposed elevations to s specific range of stations or the full alignment, under menu "profiles/ FG Vertical Alignments/Create COGO Points" I am looking for the same one in C3D.
2. How to add connecting alignment label and station in profile view. For example I have an main alignment and in-between lot of other alignments are meeting with this alignment.
I want to show in profile view of the main alignment the meeting alignment's name and the station it meets with?

In C3D 2012, when I needed to know what elevation a surface contour was at, I simply hovered my mouse near the point in question and a small window would tell me what elevation my mouse was hovering at. Now, in 2013 I am trying to do the same thing but the little window only has the name of the surface and no elevations. So, how am I supposed to know surface elevations on the fly? Is there some setting to turn that back on?

We have a good size channel and the section for the channel varies quite a bit. We want to find the volume excavated in the channel between 2 elevations (it is the area of sand per the goetech report)? A template was not used to create the channel surface, breaklines and gradings were used.

I need to project a surface/grading (or something of that nature) across my berm and have it intersect with the inside bank. This is better explained if you see the attached image. In the plan view you see 4 featurelines. Outside TOE, outside TOB, inside TOB then inside TOE. I need to project the outside TOE across the berm (shown in the section view) then create a new featureline where the line and inside slope of the berm intersect. Note that all the elevation shots vary as does the widths across the berm. What's the best way to do this?

I have a survey figure that no matter what will not come in with the correct elevations, its a spline (continous) curve that the elevations get blow up on.
Only thing I can think of is the when it starts to interpolate the curve it cant get the elevations correct, this only happens in the curved area, once it goes tangent everything goes back to normal.

We are running Civil3d 2012. When converting a line or 3d poly to feature line, or just creating one it adds elevation points where it crosses surface breaklines even if you do not assign elevations. We want the feature to just have 2 elevations. The beginning and end. Is this a bug? Or is there another setting somewhere?

I am working on laying out data for some survey crews along the centerline of the road. I have a BC and EC elevation, but the vertices along the CL are at different elevations, which were the original elevation of the poly line before being transformed into a 3D polyline. Is there an easy way to make the full line follow the slope from BC to EC other than manually shifting the vertices?

I graded a commercial site with mostly feature lines. I added points where I needed them to get everything to work. After modifying my surface, I suddenly have zero elevations randomly throughout my site. They don't make any sense why they appear. Some are just added to my drawing and others are existing points that were changed to zero. I can go to a back up drawing from a few hours ago and redo some grading, but I would like to know if there is a way to just erase zero elevations from the surface. I remember LDD was able to create surfaces ignoring elevations below a set elevation.
