i am located in Greece and the current progection is GGRS87 .
before the GGRS87 we had a system named HATT with the folowing info:
maps 1/5000 based on the Bessel ellipsoid (1841)
i have many drawings with point coordinates in the old system. is there a way to transform them in the new projection?
what else info is needed for the transformation.
My group is trying to convert a dwg from one coordinate system to another. The original drawing contains points, blocks, etc. in 1 system and we need it in a different one. We tried attaching the dwg to a new map with the new system using a layer query, but this did not appear to bring in the objects into the new system.
"Structures" is in the original system (OR83-NF), "StructuresHarn" is in the desired system (ORHP-NIF)

View 3 Replies View RelatedI just ran into a projection issue with a couple of AutoCAD files. There is a possibility that one of the files was originally in Microstation and in meters before it was converted to AutoCAD but I'm still trying to confirm this now. The problem that I am running into is that AutoCAD Map doesn't allow you to xref or attach other CAD files and use different projections. I have one file in Maryland State Plane, Feet and a second one which appears to be in Meters and I can't get them to overlay or for the file in meters to come in at the right location when it is xrefed.

I am given with the origins of both system. For NAD 83, it is N6360000 E467000, for the project it is N50000 E8000. I tried to do the transformation using Toolspace->Settings->Drawing Settings->Tranformation, and changed the Local Northing/Easting and Grid Northing/Easting, but does not seem to solve the problem.

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 .
if i have one feature line i want to project to all sections in a sample line group it would seem you should be able to pick the one line and assign in a label style and you would be done quick and easy. instead if you pick the multiple projection option you get this percentage distance box and it tend to grab stuff you don't want.

View 3 Replies View RelatedI am having difficulty projecting an existing feature line at a specified tie-in slope. I have a steep (3:1) feature line that I need to project at a specific slope (2.5:1)to intersect a surface model. When I create the grading object the generated grading object is not 3:1 along the feature line and 2.5:1 perpendicular to the feature line. Instead I am left with a new slope that is 1.9:1 between the generated contours. I have attempted slope to surface as well as slope for a distance.My design criteria is to not exceed a 2.5:1 tie-in slope.

I have some points in a drawing set up in a coordinate system and using a specified point file format, I successfully exported them to another coordinate system for use by our surveyors. I also wanted the pipe route in my destination drawing so I created a shp file from a polyline representing the pipe route in the original drawing using Map 3D Export. When I imported the shp file into my destination drawing there appears to be a slight horizontal difference from the point locations. The shp file doesn't land directly on the points.
To try another comparison, I ran a query on the pipe route to perform a manual coordinate system transformation. The result of this is the exact same as the shp file.
My questions are, which method (exporting points vs. shp files) results in the correct coordinate transformation and why are they different? When exporting points I am not using any specific transformation settings, I am simply selecting the destination coordinate system. When exporting a shp file, Map 3D creates a prj file from the specified coordinate system in the drawing. Are there any other settings I need to adjust to get the same result with both processes? The only thing I can think of is I only have the coordinates out to 4 decimal places in my point file format, do I need to go out farther?
I have a created a TIN surface with a DEM file. Drawing coordinates are State Plane NAD 83 feet. DEM file coordinates are UTM NAD27 meters. Surface is shifted approx. 835 miles east.

I have started to use CIVIL3D 2007 instead of LAND-DESKTOP 3.
My question is: When I used LDD I created a surface, then drew a polyline and by right-clicking chose "Project object".
This option produced many new points along my polyline which I used for my design.
When I tried this with CIVIL 3D I couldn't find this option.
I can create a quick profile, however, this is not good for me because I need the data as a collection of points with coordinates & elevation, and not as an image.
Is there any way to produce a projection on a surface (from a polyline)?
Or getting some information from the quick profile in the way I need?
I have a .dwg file with an AT-LCC projection assigned to it. There are some .shp files connected to it.
Can I choose the projection of to-be-imported-points when I import some laserscan-files in ASCII format? So I can tell AutoCAD: these points are in MGI-AT.AUT-Central/GK projection, please convert them to my desired projection.
There is a method which takes much too long:
open a new document assign the origin-projection (here; MGI-AT.AUT-Central/GK) to the fileimport the pointsexport the points as .shp file, define a projection-system conversion to target projection (here: AT-LCC)open the file with the target projection assigned to it (here: AT-LCC)import the .shp file
The transformation settings are changing every time a drawing is reopened. The computation method is switching from "reference point" to "unity" - see attachment. This is causing the software to use a scale factor of 1 instead of the computed scale factor at the defined reference point when scaling our points from state plane to our local ground system. This completely screws up our entire survey workflow that we have been using for almost 2 years. We had no issues like this in the 2012 or 2013 versions.
View 1 Replies View RelatedIf you have a dwg that is, say, done in west zone but some agencies want you to provide a table of west and east zone coordinates is there a transform function that will do this in a label?
I would still wan everything in the dwg to be in west zone but be able to display coordinate values in other zones.
I have geotif images that I've purchased from Washoe County GIS. They have world files that work great with data connect. That is, as long as I want to work at sea level. We have a Combined Factor mandated by the County for all record maps. it's a simple grid to ground factor. I can set this factor in the drawing settings and import my sea-level coordinate files just fine. The pboblem is that I can't get the Data Connect to work with the transform settings.The problem is the same with Geotif files and SHP files. I've tried using an x-reference drawing to insert the Geotif and then scale up the geotif but the imagery doesn't scale up.
Is it a program bug that keeps Data Connect from recognizing the transformation settings?
How to share custom projection files with multiple users? I created a custom projection for C3D on my computer, now I need to give it to several other people. Can't seem to find where this file is stored.
C3D - 2014,
When we apply surface projection gradings to feature lines, we get locked vertices on the feature line wherever the grading transitions from cut to fill. In turn these vertices create segments in the feature line which influence any labels applied to the line. I don't want a bazillion segment labels on my FL. I only want segment labels between the physical vertices and elevation points. Is there a workaround or is an enhancement request in order?

Until now I have used Civil 3D for small projects. Now I'm starting a large project, 30 parcels, 5 roads in rough terrain.
Earlier I got some problems with some surfaces of the new construction that unwanted connected together. This time I want to get control of all small new "constructions" (parcels and roads) and connect them to the surface. I realize the original surface will be covered 100% of new terrain. How will I be able to connect all the surfaces together so that I can eventually create a single surface with all the new designs? (and run the waterdrop :-)
