AutoCad :: Adjusting / Pivoting Survey In Drawing?
Apr 3, 2012
I 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 have been given a cad survey of a friends piece of land and the house that is yet to be built. The house and land are orientated at the angle they actually are. I was wondering how to adjust the plans angle so that I can work on it using straight lines etc as I would if I was to start the drawing from scratch?
I'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.
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
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 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?
I 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 am tired of re-creating Description Keys everytime I want to bring in Survey Points into a drawing. I have tried to drag and drop, but that does not seem to work for me. I can's copy it. Is there a way to get Civil 3D 2010 Description Keys into Civil 3D 2012.
I've not used AutoCad for probably 15 years. I used it in my government job, but have forgotten many commands. I have inserted a building survey into a new DWG, and remember that I can find a dimension on that survey, and use it to begin a scale for the drawing, so that I may make additions to the building drawing.
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.
I have conducted a level survey on site and once I have loaded it in to aurtocad I need to copy them on to a drawing so can tell where abouts the level are in relation to the site. When I have done this I copy with base point and paste with coordinates but it comes up tiny compared to the drawing.
Using 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?
I copied some Survey Data of AutoCAD Civil 3D 2013 for Surveyors to my C3D 2013 machine few weeks ago. Now I cannot do the "Import point file" of the Survey2 Data B in Survey Databases, because the Survey2 Data B is locked up - see the attached file that has a red circle with an arrow on. How I can unlocked the locked Survey 2 Data in the Survey Databases.
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.
is there a command that snaps your dimensioning to changes in model space. having a hard time with this, dimisioned in paper space but to many changes and found i wasn't changing the paper space dims and decided to move all dims to model space.
I have a form for adjusting center distances between several posts, up to a total of 20 posts. The number of posts is adjustable depending on how many I need. If there is 10 active posts there will be 10 suppressed post. When there are 10 suppressed post, I don`t need them in the form. Is it possible to hide the center distances I don`t need?
Using some slightly modified code from the samples provided by Autodesk as shown below I'm attempting to draw a simple leader with MText annotation.
In the attached bitmap the top leader shows the result of running the code and the bottom one the appearance I want which is obtained by changing the AutoCAD properties of the leader under
Text Text pos vert from 'Above' to 'Centered'
I can't identify anything in the API which allows me to draw with this change, but feel it should be there. Searching the web for code to draw leaders, basically only returns minor variations on this code with only the same functionality.

We are currently STILL in the transition from LDD to Civil 3D 2013. Is there an easy way to stretch the contours within a surface without physically editing the surface. Right Now, I have a couple contours that have have spikes in them from lack of survey data. The Problem is that if I don't change the contours, I have to show steep slopes between them which I would rather not do.
Do I have to keep editing the surface to try and resolve this problem or is there a way I can just stretch the contours?
Right now I resolved the problem by coping the surface, exploding it and putting the contours on a different layer so that I can stretch them as I see fit But this is not a time effective solution.
I need to adjust a surface boundary. I need to remove a corrupted area in my surface. I do not need it. Is there any way to drag a boundary so I can exclude some of my contour area? Is there a command under settings on tool space that I may have overlooked? This surface was furnished by a client so I do not want to rebuild or alter except to exclude some contours.
The aperture size cannot be modified using the sider under options. Workaround seems to be to use the system variable “pickbox”. Occasionally it seems to also display as a rectangle instead of a square, obvious when variable is set below 10 (however, this seems to be one of those intermittent problems / might be a stand-alone graphics problem).
I can split a part into 2 solid entities, I now want to rotate one of these entities with it's features say 30 degrees or whatever and then rejoin them as a newly shaped part.
I think all this is possible apart from rotating the split solid after splitting?
I'm having a little challenge making my rendered models clear and sharp. I've tried adjusting the brightness and contrast from the exposure option, I've also tired adjusting the position of the sun via time setting but my models always look blurry and dull. I attached some of the rendered works.
I went forward designing intersection profiles with limited survey and simply made an educated guess for the secondary roads pgl tie in point. I have received updated survey and when I move the profile end point to meet existing grade it adds another pvi effectively holding the profile grade I set preliminarily. I'm keeping the lock point. Is there something with the return/ offset profiles preventing this edit? What is the proper work flow?
