![]() Obviously we have the point cloud to refer to, but it has some limitations, and we’d ideally like to create models of specific features to which we can tie attributes. In this blog we look at a variety of (mainly experimental ) techniques that we have developed to attempt to capture the finer details. Our London office was quite well represented, but the architectural detail in our Leeds office features was largely lost – you can still appreciate the chimney breasts and high ceilings, though! In the l ast blog we described how we created basic, but very usable, 3D model s of our offices using the point clouds for reference. Missed the early instalments of the series? Check out Part 1, Part 2, Part 3, Part 4, and Part 5 first. In the next of our blogs on Building a Digital Twin within the ArcGIS Platform, we l ook at extracting architectural detail and assets from the point cloud data of our offices we collected using a d rone and a l aser scanner. Health, Safety, Security and Environment.The Result By following these steps you can bring your model back and forth between the two programs. ***Note you will add the same model over and over again with ever click until you deselect the “Insert Tool” When prompted, navigate to the location of the supported 3D model file on disk.Click the desired location of the multipatch model in the 3D view.Select the Insert tool under Construction Tools.The Insert tool will appear in the Construction Tools window.Click the multipatch feature in the Create Features window.Click the Edit Placement tool on the 3D Editor toolbar.Begin a 3D edit session by clicking the 3D Editor drop-down and click “Start Editing”.Add an empty or populated multipatch feature class into ArcScene or ArcGlobe.Name the File something relevant and save it in a familiar directory as a COLLADA.Returning to ArcScene Getting the model back into ArcScene is almost the exact opposite first we want to export our finished model in Sketchup by “Selecting” File > Export > 3D Model Be sure to group all elements before saving. Rendering tasks Perform all necessary rendering tasks. Here you will want to decide if you want to merge coplanar faces – typically for texturing the outsides of builds you do want to merge.Navigate to where you just exported the Collada file from ArcScene and make sure your file type is COLLADA in the drop down menu.Open Google Sketchup® and choose a template that is in the same units as your projection in ArcScene (i.e.Convert to Collada Again in the ArcToolbox > Conversion > To Collada > ‘Multipatch to Collada’ tool is what we will use to output a file in a format Google Sketchup® will recognize. Input the corresponding Feature layer to be converted into a Multipatch, put it in a familiar directory for output.“Layer 3D to Feature Class” is the tool we will use toĬonvert the extruded features to a ‘Multipatch’ feature class. ![]()
