The Shapefile format is an old format which has no scope for a password or encryption. So all the solutions that you will find, will be built on top of the existing standards, and hence will not be standard across various applications. A solution that will work with ArcGIS will not work with Qgis and so on. Having said that, I have seen a few low-tech ways ...

LibreCAD is one open source project that I found promising. It's GUI is very similar to AutoCAD. This makes it quite easy for AutoCAD users. At present it does not support .dwg format. But you can work on dxf files.

It seems to me that the main problem for you is to introduce some order to your tons of DWG/DXF files with information (in several layers). Regardless of choosing software/tool I can recommend you to describe your data. Here is some thoughts: You should develop some kind of unique codes for all types of your features. It can be one attribute or several or ...

I think you'll be happier with CAD software than with a GIS. QGIS has a toolset called CADTools but you'll have difficulties importing any PDF or SVG.

There is quite a bit of missing information in your question. Despite that here are some ideas. 1. I will assume your data is polygon. You should attempt to export the cad file as polygon and point files seperately. The text will be your point file with the label point as the location. and the string value as an attribute. 2. use a spatial join (arcmap ...

There are several other questions here that have addressed this. It is not straight forward. I'll assume the worst for now. Your drawing is probably not in a coordinate system. Most drafting is done an a "blind" cartesion system. Meaning they just take a blind stab at where they will start drafting and measure with whatever units happen to be the ...

If you're looking for free as in I don't want to pay money for a CAD program, I recommend you look into Draftsight edit: Just in case, you wanted to learn the software or you're coming from AutoCAD, I've developed this tutorial / cheat sheet: http://97.107.136.148/Autocad_tutorial_v1.pdf a few years ago. Unfortunately, since it's a numeric IP address, ...

Quick guess for question #1: QGIS only projects vertices and your straight lines have only an start- and endpoint?

There are a several tools I would suggest. Depending on what brand of CAD will be the preferred software. If Autodesk is in the mix then I strongly suggest autodesk map3d. If civil engineering is the industry then civil3d has map in it also (along with many engineering tools). As you have noted the migration path you are suggesting is not the norm. In the ...

If you are talking about migrating data, then FME could definitely help you out.

You can use the Import From CAD Conversion Tool in ArcToolbox (does not require interoperability extension) "The Input files parameter will allow the addition of different kinds of CAD data (DGN, DWG, DXF) in one operation." Go to the tool help for more details on Microstation projection, post-processing for joins and or data relationships, etc. ...

Given that your autocad version is 12+ years old it may be an issue with autocad dwg or dxf file format version (major format version: http://en.wikipedia.org/wiki/.dwg#Version_history). You should try to open it in a newer version of ACAD, or try saving it into an older format.

autocad map 3d will easily geo-reference your dwg/dxf files and allow conversion to 12 gis formats. Unless you add FME desktop also (FME extsion for ArcGIS). Then with FME extended to arcmap and autocad you have all ~275 formats. But doing it through map3d you have access to some particularly useful tools. (i.e. select by layer, color, linetype, or even ...

FME can do Shape to AutoCAD Blocks This was modified (for FME 2013) from the original on FMEPedia http://fmepedia.safe.com/articles/How_To/Creating-AutoCAD-Blocks-with-FME Product: FME Desktop http://www.safe.com/fme/fme-technology/fme-desktop/overview/

@mapperz provided this answer: http://enja.org/enjshape/ This is a great plugin and works like a charm. It is, however, very sensitive to coordinate systems, so I would suggest: make sure your SHP is in LAT/LON (WGS84) start a new sketchup document in 'metres'. Worked for me! Thank you again, @Mapperz!

JPG is not a spatially aware raster format, and the process by which different programs independently georeference rasters and save that transformation information doesn't necessarily transfer. I see two potential options. In CAD export the image as a georeferenced tif file (you may or may not be able to do this depending on what software you have), or ...

As a person with this background I can talk directly to that topic. What employers are often looking for is people that have production linework experience; or the ability to do solid and consistent data creation work. CAD is often a lot less subjective; whereas GIS with is background in Enviro/Planning arenas has less of a rigid expectation.CAD shops often ...

It sounds like you have some major batch processing and therefore, I would be inclided to script this. Doing this all by hand might be feasible but a pain. At least with a script, if you muck something up you can just correct the script and re-run. Also, you have a chance to unify a lot of the non-standard naming etc by using regular expressions and ...

I am in the GIS department of a civil engineering project and when I was hired, the job specification stated that CAD experience was ideal but not essential. I was hired even though I had no experience of CAD and have subsequently been given some cursory training in Civil 3D. In a project of this scale the requirement for the GIS staff to 'know CAD' is ...

I havenĀ“t tried any of those yet, but these might be worth taking a look: FreeCAD, BRL-CAD, Archimedes

If you have access to an ArcEditor (Standard) or ArcInfo (Advanced) license of ArcGIS Desktop there is a tutorial available on Using geodatabase topology to fix line errors such as undershoots and overshoots. Unfortunately, the options for ArcView (Basic) are more manual and will involve extending lines and or trimming lines.

In ArcMap a DXF file is read only so you need to export it, there is no alternative. Use the CAD to Geodatabase tool.

While I don't know exactly what method you used to georeference, it sounds like you have a georeferenced image and CAD data with no defined projection. The steps you performed and the order in which you did it is going to dictate the outcome. If you added the image and cad data to a map document, then your dataframe should have been set to projected NAD83 ...

I've never tried it, but here is mention of sketchup on linux. You can place a sketchup model into google earth.

First of all, you need to know which coordinate system your data is in; the CAD guys should be able to tell you this. In the UK, for instance a common coordinate system is OSGB36. See the FAQ for information on projections and datums. Next, you need to know the coordinates of a point (normally the origin) in the CAD file. Technical artists often don't care ...

If you're not afraid of using command-line tools, then GDAL/OGR is your friend! It is a free set of tools for manipulating raster and vector data that has become pretty much the de-facto standard. It will take Autocad DXF and Microstation DGN (and others, but those are the only CAD formats I can see in the list), and will convert them to pretty much any ...

Ok well a major difference you will find is CAD is geared towards a much more precise world. It supports more types of engineering based geometries and workflows to support dedicated workflows. The two industry leading CAD packages (Bentley and Autodesk) are easily as powerful as ESRI GIS but also tend to have a much stronger toolbox built behind them to ...

I use GlobalMapper to migrate GIS data (shp) to dwg, dwg to shape, kmz and many other vector data. It works well.

You can also look into the AutoCAD university. Free one year edu license and all the tutorials you can stand. That being said, I am on the other side of the fence and use GIS in Public Works. Engineerinfirms give us spatially correct surveys, plats, etc., and I add the tabular data that goes with it. Understanding the concept s of both are key. How they are ...

This is a loaded question. You can do a great deal more with map capable versions of AutoCAD than just drafting related activities. Really there are too many possible functions to discuss; especially in reference to the AutoCAD Civil 3D environment. In many cases, a client will have CAD drawings that serve as a starting point in a broader project, or from ...
