I've been sent a survey drawing with elevations. The format is a block, but it's not a named block. Each entity has it's own block name. So, I'm having trouble getting at the elevations. I can't seem to export and get the elevation or Postion Z.
I've tried exploding these blocks, but all I get is a couple of polylines, and some text. Useless. I've attached a sample drawing with a couple of these points.
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.

I have imported a survey file. When I insert the points into the drawing, the elevation changes to something that isn't even recognizable. When I view the point in the survey tab, the elevation is correct, when I view the point in the prospector tab it is different.
View 4 Replies View RelatedI'm exploring the option of going from normal autocad and PDS (for our road designs) to fully using Civil 3D 2013.
Generally we only recieve a survey drawing as a 2d cad file with height points represented as 2d text.
In PDS all we need do is 'convert text to point' and create a ground model, this gives us a 3d ground mesh to work with.
In Civil 3d i've found 'movetexttoelevation' but now i'm stuck with adding a point at the node of the text object, and then I need to creat a surface model to overlay a 2d siteplan andstart creating our roads.
Here is my procedure.
1. Import survey point via ascii file into a new drawing call it Field-dwg.
2, Create a survey data base
3. Import all points in the the data base under import event.
4. open existing drawing, work-dwg, import points as needed from the Survey Data Base.
Problem : Survey points needs be renumber.
I goto field-dwg, and fix the points (renumber).
open survey data base for edit, and import Event, field-dwg/points/update : nothing happen
also try Import Event, field-dwg, survey points, update : nothing happen
so I re-import the points, all is good.
Then I goto work-dwg, and try to update the point, nothing happen.
I imported survey data from a file into the drawing and created a surface from the points and figures. No problem. Engineer wanted to change the datum from assumed to known. At this point all figures have been copied to a new layer flattened and changed to 2D polylines in order to hatch. Then the figures reimported. I raised all the points with the edit datum and raised the figures with edit survey figures. Surface was adjusted and tweaked. Everything was fine. I open the drawing and all the figures are back at assumed datum and the points are on the right datum. Now when I tweak the surface it uses the bogus elevations from the figures. How can I get my figures to save the adjusted elevations?
View 4 Replies View RelatedI have an AutoCAD file which includes 3d points and lines which represent an existing ground survey. The scheme is approx. 8km and points are spaced in a dense grid. The survey was undertaken using aerial (Lidar) methods, before being rationalised using aerial imagary to identify linear features such as kerbs, fencelines, etc, which are included as 3d polylines. Items have been grouped by the surveyors and adopt individual cad layers and linestyles, etc.
Basically, I want to incorporate all of the points and all 3d polylines into my Civil 3d Survey database in order develop a roads design.
I'm looking to change an elevation of a survey point within a drawing. I can see where it is possible to manually unlock the points from the Survey Database to allow the user to edit the point. I'm not seeing a method or property in the API Help for 2013 to do the unlocking with code.
Also is it possible to convert a Survey Point to a regular Cogo Point through the code? Or do I have to delte the point and then recreate it as a COGO point? I think this will be my work around if the above doesn't work.
Is there a way to link the path of the survey data base in the drawing, so I do not have to set the working folder every time?

A quick lisp routine to extract the elevations of a selection set of 2d polylines? I have a massive "contour" file composed of 2d polylines with elevations.

View 9 Replies View RelatedUsing Civil 3D 2013Coordinates coming out of survey equipment are modified state plane GROUND (scaled up from the origin by the combined factor).Drawing is setup with state plane coordinate system with user defined transformation to establish geodetic reference and the ability to label lat/long or import Bing map data.Survey database is setup with "No Datum, No Projection" (data is already at ground, I don't want ot transformed).Import style is PNEZD and is set to use Northing/Easting not Grid Northing/Grid Easting.After importing points into survey database, coordinates of survey points match the CSV. This is good.After importing points from database to drawing, they are taken as grid coordinates, are scaled again and are off ~5,300 feet northeast.Why would Civil 3D assume the points in the database are grid and scale them when the import style used did not specify grid? Is there a setting or something I can do to tell Civil 3D to leave my coordinates alone?

View 1 Replies View Relatedhere's my process:
1- Import the asc file into my drawing.
2- Convert the asc file to a FBK file
3- Import my FBK file. The survey figure linework generated doesn't overlay my previously imported asc file. I checked the FBK file and the coord's match the asc file. I'm confused as to why the survey figures don't overlay the survey points from the asc file, since the coords match in both? The survey figures are all shifted .7' and 54deg. from the points. The elevations are all good on the survey figures, as they match the survey points.
So my quick fix is to explode the survey figures, since I don't really need them for what I'm doing, and then select all the 3d polylines and move them to them to an appropriate survey point. Everything then looks fine and I can get the job done.
However, I would like some insight as to why this might be happening. It's strange that the FBK and asc coordinates match, but the survey figures aren't lying over them.

View 8 Replies View RelatedI have a survey for a residential property with all the coordinates which I input into CAD, using the tutorial on this site. @25<S25D14'36"E..etc
The house & property run in a NE/SW angle which isn't an angle I want to do work in. If I pivot the drawing so the house & lot are parallel with the screen the cursor takes on a new and weird shape.
I'm wondering if people do anything with the x/y coordinates or settings in the drawing? I thought a drafter told me there is a way to deal with this when setting up the drawing but I can't remember for the life of me.
I created the attached block to add spot elevations to a drawing. The block has attributes allowing elevations to be manually typed in, but also includes many dynamic features for rotation, lengthening, mirroring, etc. The block was created as an annotative block.
The block and all of its features work perfect as long as the dynamic features (rotation, etc) are not used after additional annotative scales are added. I often times have a drawing set at 1:10 or 1:20 scale and need to do an enlarged detail at 1:5.
What I would like to do is have this block set at 1:10 scale and 1:5 scale and manually rotate it (ideally using the dynamic features) at different angles for each scale. Is this possible and if so, why is it not working with this block? This works flawlessly when using annotative multileaders, so why shouldn't it work with blocks or is this just too labor intensive for the software?
I have also tried attsync, etc. and often times when rotating at different annotative scales, the text attributes go "bonkers" for the opposing scale when applying attsync.

View 4 Replies View RelatedIn 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.
