If this is your first try at CAD modeling, read this article first to learn about the basics of CAD data importing and development. A printer friendly version of this article is available. Store the moabroad and clippol1 shapefile sets in Moab_CAD\SHPFiles\UTM27z12. Place the moabtopo.dwg, moabutil.dwg, and wldfile1.wld files in Moab_CAD\DWGFiles\Local.

If you completed the model described in "Modeling CAD Data in ArcView GIS" in the October≭ecember 2000 issue of ArcUser magazine, you will use the same directory structure (shown in Figure 1) and the CAD filtering and registering techniques learned previously for this project. Planners and emergency managers use this data to plan and mitigate natural hazards including floods and wildland fires.
Displaying this data in a three-dimensional model shows the relationships between several utility sets, including water, sewer, gas lines, fire hydrants, poles, and light poles, in an older part of town affectionately called Steenville after Charlie Steen, Moab's "Uranium King." The data used for this exercise is actual infrastructure data from Moab, Utah, used here by permission. This article will use CAD data from the City of Moab to model terrain, roads, and above-ground and buried utilities. Themes can be suspended on, above, or below a digital terrain model to show relationships between data sets. This imported data can be registered into the same coordinate systems as other data by using a world file. Using the CAD Reader extension that ships with ArcView GIS, CAD data can be added to a project. CAD allows engineers to create, edit, and present vector information in local or global coordinate space. Transportation specialists, civil engineers, emergency managers, public planners, and others use CAD to design, build, and monitor construction activities. All these themes will be moved into ArcView 3D Analyst to be displayed in three dimensions. Line and point data for roads and utilities will also be extracted.

This article will show how to use contour lines and spot elevation extracted from CAD layers to generate triangulated irregular network (TIN) themes. Using a world file, this data, originally created in a local coordinate system, was registered into Universal Transverse Mercator (UTM) and displayed with digital elevation model (DEM) data. That article, also available from the ArcUser Online Web site, showed how to load, filter, and display Computer-Aided Design (CAD) data for Moab, Utah, in ArcView GIS.

The second in a series on modeling CAD data describing the City of Moab.Įditor's note: This article builds on the CAD processing skills learned in "Modeling CAD Data in ArcView GIS" which appeared in the October-December 2000 issue of ArcUser magazine. We trust you enjoy our vast collection.CAD Data in Three Dimensions By Mike Price, Esri Over the past twenty+ years we have collected thousands of CAD symbols. A PURGE and AUDIT has been run on each block. Most blocks are on layer 0, byblock or bylayer and insert at 0,0,0. They have been carefully screened and cleaned.

So you can open them in whatever version of CAD software you have. These free files are mostly saved in an AutoCAD 2000 DWG format. For example: BricsCAD, Chief Architect, DesignCAD 3D Max, DraftSight, LibreCAD, Microstation PowerDraft, nanoCAD, ProgeCAD, Sketchup, Solidworks, TurboCAD, Vectorworks, GstarCAD, IntelliCAD and ZWCAD.
While we have created these drawings in AutoCAD, they are compatible for use in other 2D software. These simple details will be useful in any DWG compatible CAD software package. Our goal is to build a resource, the CAD user can use as the go-to library, for CAD drawing. A CAD block is useful for the Drafter, Building Designer, Architect or Engineer. We are a collection of DWG files for use in computer aided design software (like AutoCAD).
