Problem and Objective
As a GIS analyst for NC State University, supporting campus planning and facilities management, I'm asked to develop a geodatabase to be used for future management of campus buildings and related "facilities.". The learning objectives for this assignment is to understand basic data structure of CAD created data compared to Esri format feature classes, georeferenced a CAD dataset in ArcGIS Pro and perform data conversion from CAD format into a geodatabase.

Strategies: For this problem, I used ESRI's ArcGIS Pro 2.8 along with the Manage CAD tab to georeferenced our AutoCAD and place it over the orthophoto. For this project, the instructor provided us with the data: 1. NC State University Masterplan - 2005 CAD drawing file: NCST_Masterplan05_edited2.dwg and 2. Campus orthophoto - NCSU2017-3-q50c1.jpg (70 MB; read the read_me.docx file). I used tools such as manage CAD layer and add control point. In the second part of the assignment consisted of converting some of my polyline data into polygons and adding specific data to my geodatabase using geoprocessing tools such as Line to Polygon and Feature class to feature.
Methods: To solve this problem, I obtained AutoCAD and a Raster image data from Moodle and added the layers into ArcGIS Pro. The first step was to use define projection tool match the Orthophoto and the AutoCAD to the same coordinate system: (NC State Plane Coordinates, NAD 1983 (NSRS 2007) feet
(NAD_1983_NSRS2007_StatePlane_North_Carolina_FIPS_3200_Ft_US). Next, I used georeferencing tools to superpose the AutoCAD layer on top of the Orthophoto. Then I used to manage CAD layer tool used to drag the AutoCAD layer on top of the Orthophoto followed by using Add control point tool to fixate the AutoCAD into the Orthophoto using reference points from both layers. Next, used polyline to polygon tool to convert Line layers for buildings into polygon layers for better data representation. The last part of this assignment consisted of Converting AutoCAD data into ArcGIS file geodatabase by right clicking on the layer I am interested in the content plane then inside the data tab use export feature tool which converts the AutoCAD fife into ArcGIS file and add it to our geodatabase.

Applications and Reflection
Computer-aided drafting is also called computer-aided design. CAD is a computer software or system that is used to create 3-D and 2-D representations or models of various tangible objects such as bridges, buildings, or mechanical parts.
New problem description: For my example scenario I will develop a geodatabase for Scheck Forest confiners to be used for future harvesting and planting operations.
Data Needed: To do so I will obtain data from an Autodesk AutoCAD software and a Landsat8 raster image for Raleigh using the USGS website.
Analysis procedure: To solve this problem, I will define the projection for both then open manage CAD layer tab to georeferenced the layers and superpose my CAD layer on top of the raster image and fix it by adding control point to reference point.
