3D technology has made exceptional improvements that have turned basic shapes into realistic objects. The applications of 3D continue to expand with users applying 3D to topics such as\u00a0digital twins, architecture, and emergency management.\u00a0With advancements, users are moving to 3D for nuanced analysis, visualizations, and mapping.<\/p>\n

Previously, I wrote about\u00a0how to add 2D features into a 3D scene<\/a>.\u00a0That was to help users dabbling in 3D GIS for the first time and adjusting 2D data for 3D visualization. But how do you officially convert 2D z-aware features, such as building footprints, into 3D features?<\/p>\n

In this blog article, I will continue with the Tennessee Tech University mapping and cover how to transform 2D features into multipatch and 3D object feature layers (3D-OFL). I’ll demonstrate two methods:\u00a0the Layer 3D to Feature Class<\/strong>\u00a0tool and\u00a0Copy-Paste Special<\/strong>. The Layer 3D to Feature Class<\/strong> method can be run for point, line, and polygon features, but Copy-Paste Special<\/strong> also works\u00a0with extruded polygon features.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2502382,"id":2502382,"title":"Tennessee Tech","filename":"TennesseeTech01.png","filesize":1270623,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/TennesseeTech01.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/3d-gis\/transform-2d-building-footprint-polygons-into-3d-buildings-using-3d-object-feature-layer\/tennesseetech01","alt":"3D scene of Tennessee Technological University campus","author":"210022","description":"","caption":"","name":"tennesseetech01","status":"inherit","uploaded_to":2502332,"date":"2024-09-24 18:07:03","modified":"2024-09-24 18:08:13","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":1211,"height":787,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/TennesseeTech01-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/TennesseeTech01.png","medium-width":402,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/TennesseeTech01.png","medium_large-width":768,"medium_large-height":499,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/TennesseeTech01.png","large-width":1211,"large-height":787,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/TennesseeTech01.png","1536x1536-width":1211,"1536x1536-height":787,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/TennesseeTech01.png","2048x2048-width":1211,"2048x2048-height":787,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/TennesseeTech01-716x465.png","card_image-width":716,"card_image-height":465,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/TennesseeTech01.png","wide_image-width":1211,"wide_image-height":787}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

For this project, I’m focusing on building footprint polygons. A few important points: this data source was created in ArcGIS Pro, the data is z-aware, and displayed in a 3D local scene. Since I plan on creating new data, I\u2019m going to work in a local scene rather than a global scene. For more information on local scenes,\u00a0see Scenes in the ArcGIS Pro help.<\/a>.<\/p>\n

To follow with this workflow, find an area you want to work in and create a z-aware polygon feature layer in a local scene for building footprints and generate a few examples to work with.\u00a0For steps on this, see\u00a0How to add 2D features to a 3D scene<\/a>.<\/p>\n

Prepare the 2D features<\/h2>\n

Now that I have created a few examples, I must prep the data. First, I establish a height for the buildings polygon layer. One way to accomplish this is by adding a new field to the attribute table for height, and then input different values for a range of heights. This will create a more realistic and diverse look for the university campus.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2502402,"id":2502402,"title":"Attribute Table","filename":"AttributeTable02.png","filesize":5474,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/AttributeTable02.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/3d-gis\/transform-2d-building-footprint-polygons-into-3d-buildings-using-3d-object-feature-layer\/attributetable02","alt":"Attribute table with Height field added","author":"210022","description":"","caption":"","name":"attributetable02","status":"inherit","uploaded_to":2502332,"date":"2024-09-24 18:09:32","modified":"2024-09-24 18:11:34","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":349,"height":103,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/AttributeTable02-213x103.png","thumbnail-width":213,"thumbnail-height":103,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/AttributeTable02.png","medium-width":349,"medium-height":103,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/AttributeTable02.png","medium_large-width":349,"medium_large-height":103,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/AttributeTable02.png","large-width":349,"large-height":103,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/AttributeTable02.png","1536x1536-width":349,"1536x1536-height":103,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/AttributeTable02.png","2048x2048-width":349,"2048x2048-height":103,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/AttributeTable02.png","card_image-width":349,"card_image-height":103,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/AttributeTable02.png","wide_image-width":349,"wide_image-height":103}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

Extrude the polygons<\/h2>\n

Extrusion is the process of stretching a flat, 2D shape vertically to create a 3D object in a scene. For example, you can extrude building polygons by a height value to create 3D building shapes. Only points, lines, and polygons support extrusion.\u00a0<\/em>For more information, see\u00a0Extrude features to 3D symbology.<\/a><\/p>\n

To alter the feature layer’s extrusion setting,\u00a0select the layer\u00a0in the\u00a0Contents<\/strong>\u00a0pane, browse to\u00a0Feature Layer<\/strong>\u00a0on the ribbon, and click the down arrow for\u00a0Type<\/strong>\u00a0in the\u00a0Extrusion<\/strong>\u00a0section. I selected\u00a0Base Height\u00a0<\/strong>because I want the vertices of my polygon to act as the base for my new 3D building. From here I choose\u00a0Height\u00a0<\/strong>on the\u00a0Field\u00a0<\/strong>drop-down menu\u00a0<\/strong>and\u00a0US Feet\u00a0<\/strong>on the\u00a0Unit<\/strong>\u00a0drop-down menu. This approach uses the\u00a0Height<\/strong>\u00a0attribute that I created from that layer’s attribute table as the parameter for the new 3D buildings. As soon as I select the\u00a0Height<\/strong>\u00a0attribute, all polygons are extruded to the height determined in the attribute table.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2502462,"id":2502462,"title":"Base Height","filename":"BaseHeight03.png","filesize":537903,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/BaseHeight03.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/3d-gis\/transform-2d-building-footprint-polygons-into-3d-buildings-using-3d-object-feature-layer\/baseheight03","alt":"Base Height extrusion type","author":"210022","description":"","caption":"","name":"baseheight03","status":"inherit","uploaded_to":2502332,"date":"2024-09-24 18:12:48","modified":"2024-09-24 18:13:13","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":1186,"height":664,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/BaseHeight03-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/BaseHeight03.png","medium-width":464,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/BaseHeight03.png","medium_large-width":768,"medium_large-height":430,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/BaseHeight03.png","large-width":1186,"large-height":664,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/BaseHeight03.png","1536x1536-width":1186,"1536x1536-height":664,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/BaseHeight03.png","2048x2048-width":1186,"2048x2048-height":664,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/BaseHeight03-826x462.png","card_image-width":826,"card_image-height":462,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/BaseHeight03.png","wide_image-width":1186,"wide_image-height":664}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

Using either option will allow you to extrude your footprints into a 3D shape. Keep in mind these extruded shapes look like 3D models, but they are still considered polygons in ArcGIS Pro. This means you will not be able to texture the shapes, edit the shapes, or perform any operations that specifically work with 3D objects. You must complete another step to transform them into either a multipatch or a 3D object.<\/p>\n

Method 1: Layer 3D to Feature Class Tool<\/h2>\n

With the data prepped and ready to use, there are two methods to transform the 2D feature data into 3D: geoprocessing tools or\u00a0Copy\/Paste Special<\/strong>.\u00a0Copy\/Paste Special<\/strong>\u00a0will be discussed in the next section. If you choose the geoprocessing route, the options are\u00a0Layer 3D to Feature Class<\/strong>\u00a0and\u00a0Interpolate Polygon to Multipatch<\/strong>. I recommend the\u00a0Layer 3D to Feature Class<\/strong>\u00a0(3D Analyst)\u00a0tool<\/a>\u00a0over\u00a0Interpolate Polygon to Multipatch<\/strong>, because it works with more than one feature class and can be used on points, lines, and polygons, but keep in mind both geoprocessing tools require the\u00a03D Analyst extension\u00a0for ArcGIS Pro.<\/p>\n

To access the\u00a0Layer 3D to Feature Class<\/strong>\u00a0tool, click the\u00a0Analysis<\/strong>\u00a0tab on the ribbon and click the\u00a0Tools<\/strong>\u00a0button to open\u00a0Geoprocessing<\/strong>\u00a0pane.\u00a0In the\u00a0Geoprocessing<\/strong>\u00a0pane,\u00a0browse to the\u00a0Toolboxes<\/strong>\u00a0tab,\u00a0expand the\u00a03D Analyst<\/strong>\u00a0Tools<\/strong>\u00a0section, expand the\u00a03D Features<\/strong>\u00a0section, expand the\u00a0Conversion<\/strong>\u00a0toolbox to access the\u00a0Layer 3D to Feature Class<\/strong>\u00a0tool (Alternatively, you can do a quick search in the\u00a0Find Tools<\/strong>\u00a0bar).<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2502502,"id":2502502,"title":"Geoprocessing","filename":"Geoprocessing06.png","filesize":118982,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/Geoprocessing06.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/3d-gis\/transform-2d-building-footprint-polygons-into-3d-buildings-using-3d-object-feature-layer\/geoprocessing06","alt":"Location of Layer 3D To Feature Class","author":"210022","description":"","caption":"","name":"geoprocessing06","status":"inherit","uploaded_to":2502332,"date":"2024-09-24 18:15:34","modified":"2024-09-24 18:15:52","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":727,"height":602,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/Geoprocessing06-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/Geoprocessing06.png","medium-width":315,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/Geoprocessing06.png","medium_large-width":727,"medium_large-height":602,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/Geoprocessing06.png","large-width":727,"large-height":602,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/Geoprocessing06.png","1536x1536-width":727,"1536x1536-height":602,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/Geoprocessing06.png","2048x2048-width":727,"2048x2048-height":602,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/Geoprocessing06-562x465.png","card_image-width":562,"card_image-height":465,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/Geoprocessing06.png","wide_image-width":727,"wide_image-height":602}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

Click\u00a0Run\u00a0<\/strong>at the bottom of the pane and give the tool a few moments to process your request.

From here, you can texture, perform analysis, or edit the buildings further using Editing tools.<\/p>\n

 <\/p>\n

Method 2: Copy-Paste Special<\/h2>\n

This method works primarily on polygon feature classes. For this method, I create a new empty feature class and paste the data inside. This method doesn’t require an extension and allows you to translate data into any 3D feature class type (multipatch or 3D-OFL). If you want a 3D object feature layer (3D-OFL),\u00a0Copy-Paste Special<\/strong>\u00a0will allow you to bypass the multipatch to 3D-OFL conversion and directly paste 2D data into a 3D-OFL.

For Fields, click\u00a0Import<\/strong>\u00a0at the top and navigate to the original feature class that contains the data. Fields from the original attribute table will be added, and any unnecessary fields can be removed by right-clicking the fields and selecting delete. It is important to match the desired fields of the created feature class with the original to maintain the data schema. If the fields match the data will transfer over, but data without a corresponding field will be lost which is time consuming to fix later. You can also define the spatial reference using the wizard.<\/p>\n

With the fields matching, click\u00a0Finish,<\/strong>\u00a0and a new 3D object feature layer is created.<\/p>\n
