What is CAD data?βArcMap
A unique feature of the DGN format is that you can save it with nonstandard file extensions. The datasets can vary in size, scale, and level of detail; they can represent information about the inside of a building at a project scale or a survey plat at a regional scale in a projected grid zone. These attribute sources include AutoCAD block attributes, attributes of MicroStation shared cells, and user-defined attributes from Civil 3D.

This can be utilized to denote content; for example, you can save a DGN file with a. Predefined field names have been established for the standard properties of CAD fields. Some user-defined attributes may contain field names that are invalid in ArcGIS Pro. A unique feature of the DGN format is you can save it with nonstandard file extensions. dxf files may also include additional information from ArcGIS for AutoCAD or AutoCAD DWG files exported from the geoprocessing tool. Computer-aided design CAD is a system of hardware and software used by design professionals to design and document real-world objects. β Clearly identify tolerances you require. After placing your file on our ftp site, please send an emial to with the file name and any special instructions you may require. Formats ArcGIS Pro support files from ArcGIS for AutoCAD and MicroStation. You can build an entire mold, insert additional parts and download the specifications and drawings directly to your CAD program. By default, the CAD entities in the CAD file are organized by geometric type into feature classes. General CAD File Guidelines β Always include your DME account number, company name, contact name and phone number with your CAD data. These default feature classes include POINT, POLYLINE, POLYGON, ANNOTATION, and MULTIPATCH. You cannot create or copy folders to this site, only files. Learn more about CAD data To learn more about source CAD data, you can reference the following topics: Topic Description The issue of scale defines a fundamental difference between how GIS and CAD systems utilize coordinate systems. In addition to Autodesk's proprietary versions, several third-party variants are also common. These feature classes are derived from the AEC objects stored in the. With this resource, drawings and calculations that used to take hours now take just a few minutes. Both formats are capable of supporting 2D and 3D information. However, please note that after entering the website, you can choose to disable cookies as per the instructions for your browser set out. This feature dataset contains a spatial reference and a collection of read-only ArcGIS feature classes. The DXF format is an interchange format originally developed in 1982 by Autodesk for enabling interoperability with other software applications. Please indicate your consent to our use of cookies and our policy by clicking Yes. Bentley MicroStation DGN The DGN format is the native file format of Bentley's MicroStation CAD software. In the absence of tolerances, DME will assume our standard tolerances are acceptable β If your CAD file is complex, provide individual plate details β If you use layers or levels in your design, please supply a legend that describes information on each layer β Do not supply cavity or core data unless required by Hot Runner Design, or place it on a layer which is easily removable β We will be machining from your data, therefore you are responsible for the accuracy of your geometry and all files provided 3D,2D, etc. CAD data CAD systems generate digital data. Formats AutoCAD and MicroStation each use a proprietary file-based vector format. Unlike a GIS, all data represented by a CAD dataset is normally contained in a single source file. Attributes from CAD properties Feature attributes are generated from the CAD entity properties. This information is included as additional CAD dataset feature class content. CAD File Transmission Options Upload CAD files to our ftp site: If you have more than one file for the same job please zip or compress into one file and copy your files to the incoming folder. Currently, AutoCAD and MicroStation are the two most widely used general-purpose CAD platforms. AutoCAD and MicroStation are two widely used general-purpose CAD platforms. The DXF format is an interchange format originally developed for enabling interoperability with other software applications. The prefered CAD formats include: Parasolid, STEP, DXF and DWG. The read-only feature dataset and the included feature classes can be added to a map or scene or used in geoprocessing workflows in the same way as any other GIS ArcGIS dataset without conversion. Computer-aided design CAD is a system of hardware and software used by design professionals to design and document real-world objects. CAD dataset feature classes When you connect to a CAD file in ArcGIS Pro, the CAD entities in the drawing are organized on the fly into virtual feature classes that resemble a geodatabase schema. This topic describes the types of attributes you can encounter when working with CAD datasets. For example, field names that begin with a number are automatically prefixed with the letter t. Both formats support 2D and 3D information. dxf files that may also contain feature class data created in Esri's ArcGIS for AutoCAD plug-in or Autodesk's Civil 3D software. ArcGIS Desktop accepts data generated by AutoCAD- and Microstation-based applications. You have two options for accessing CAD data. In addition to Autodesk's AutoCAD, several other CAD vendors also use versions of the DWG file format. ArcGIS Pro supports enhanced content in an AutoCAD. Feature classes generated using the ArcGIS for AutoCAD plug-in or the Export To CAD geoprocessing tool include their own GIS feature attributes. These MSC feature classes also contain additional metadata such as an Esri coordinate system definition. Please note: this is a secure folder which does not allow the files to be listed, you will only be able to see your file after the copy process is done and you have refreshed your screen. This topic describes in general terms the types of data generated by both systems. Organizations involved in the engineering, architecture, surveying, and construction industries use them to provide a variety of services. CAD data can serve a range of purposesβfrom a design plan that is printed as a drawing or submitted as a legal document, to a repository for ongoing as-built information. Scroll down and check them out. The CAD drawings are often a source of new infrastructure or changes to the natural environment and can be used to update GIS datasets. ArcGIS Pro reads CAD files as GIS formatted datasets to add them to maps and scenes and to migrate into GIS datasets. The types of data generated by both systems are described below. ArcGIS Pro uses the CAD graphic properties and a number of user-defined attribute sources to generate a virtual table of attributes. β Include instructions as to what to do with your CAD data. CAD entities contain various numeric and text properties that identify their symbology, as well as various parametric and user-defined descriptive attributes. CAD files are useful as map content and often depict proposed design information that tells a story. ArcGIS for AutoCAD and Civil 3D both create additional feature class content in a. At DME we have an assortment of Electronic CAD Communication media which enables customers having all levels of computer expertise to send CAD data.γ
