You can read about the details of the CAD to Geodatabase tool here: sdDrainageBasin, MiscUndergroundObstructions). Therein I name my featureclasses with a combination of capital and lowercase letters (i.e. However feature classes do allow for underscores ("_") though I have found that even these can be an issue at times. Use normal letter & number text characters only or your conversion will fail.Īlso if you are unfamiliar with using feature classes, know that the same rule applies to naming feature classes. Unlike shapefile names where you can name them pretty much whatever you want, spaces and symbols are no good with some things. One thing to be aware regarding the inputs in the CAD to Geodatabase tool: You have to be a bit carefull naming your new dataset. (The data on my screen in the attached image is an example of CAD data that has been converted to Geodatbase, all of my curves are identical to the CAD data.)ġ) First create a File Geodatabase in ArcCatalog by rightclicking in a folder and selecting New>File Geodatabase (see attached image).Ģ)Next, in either Arc Map or ArcCatalog, you open the CAD to Geodatabase tool in ArcToolbox > Conversion Tools > CAD to Geodatabase (or you can use the search tool as shown in the attached image). I work in Public Works and we deal with a lot of pipes, when those pipes have curves in them a feature class is much more usefull than a shape file.

shp file will loose the geometry of the arc and convert the arc to a bunch of vertices connected by short lines, loosing the smooth arc. When lines or polygon features have arcs (maybe circles too?) drawn in them a geodatabase will store the arc as a mathematical geometry which keeps the curve of the arc nice and smooth where a feature saved as a. This is because an advantage to geodatabases is that they store mathematical geometry.

Once the CAD Data is in a geodatabase you can always export the feature class to a shapefile, just know that if your CAD line work has curves in it you will lose some curve data converting it to a shape file. shp file, you have to convert to a geodatabase feature class which is essentially the same thing but better for many purposes like topology and relating feature classes to one another (When you are first learning about Geodatabases, know that the terms "shapefile" and "feature class" are nearly the same thing just stored in differnt ways). However, you can't convert from CAD to a. dwg to GIS is very simple using the CAD to Geodatabase Tool. Unfortunately I have no experince with the Spanish ArcGIS but I can tell you that converting from CAD.
