Likewise, if one of the TIN surfaces has a coincident boundary with the other in the region overlapping with the polygon, consider modifying the TIN's data area either through interactive editing or by using the TIN Domain tool to output the TIN's footprint as a polygon, applying a slight buffer to the polygon, and loading the polygon back into the TIN using the Edit TIN tool. If the input polygon shares coincident borders with any of the TIN surfaces, consider using the Buffer tool to slightly modify the polygon's shape. The tool may fail to generate a valid ouput if any of the input datasets have coincident boundaries with another input dataset. Point input features result in the creation of line geometry.Input the corresponding Feature layer to be converted into a Multipatch, put it in a familiar directory for output. It didn't work: my output had the same amount of entities only they all were having the same geometry. Starting from the existing 2D footprint, youll use the lidar point cloud layer to extrude it to the correct height. Line and polygon input features result in the creation of multipatch geometry. Convert to feature class In ArcToolbox > 3D Analyst Tools > Conversion > Layer 3D to Feature Class is the tool we will use to convert the extruded features to a ‘Multipatch’ feature class. I've inserted the required parameters which are the 3d layer ( not feature class) as input, an output multipatch feature class and a grouping definition by the OBJECTID field. With multipatch editing, you can create and texture complex 3D building forms.The geometry of the extruded features depends on the geometry of the input features: There may be some specialized tools for doing this otherwise, but with built in ArcMap tools this can be done even with multiple layers, you'll just have to get clever with erasing the correct sections at the correct times based on your extrusions.Only the portion of input features that overlap the XY extent of both TINs will be represented in the output. You'll end up with two version of your buildings where the 3D slice was erased. Since the slice is a large block covering everything above (or below) your slice erasing everything from the buildings layer inside it will result in a building layer that has the respective opposites left. Once you have this large area that should be covering the upwards or downwards portions of your buildings you can use Difference 3D to subtract it from your initial building multipatch. latest/help/mapping/layer-properties/extrude-features-to-3d-symbology.htm. extrude this by negative heights so that it goes through all the units. multipatch, or building layers can be shared with an associated feature. Typically you would extrude it enough to cover the entirety of your building features. draw one or more 2d lines representing the profile line seen from above. Keep in mind for fairly advanced features you may want to check that they are closed properly with tools such as Is Closed 3D and Enclose Multipatch, otherwise their could be issues with calculations later.įrom here, you can use default capability by taking your "slice" layer which I'm assuming is a 3D polygon and extruding into two versions- upwards and downwards (don't forget to multipatch the outputs as well). Which will ensure they are in a proper 3D format for calculations. Rotate: Rotate a multipatch feature to change the direction its facing. Move: Relocate your multipatch features by interactively moving them or using precise distances. What can typically be done is for you to convert your extruded layers into Multipatches using the tool 3D Layer To Multipatch. The list below represents common editing tasks for multipatch features: Attribute Editor: Create and maintain attributes for your multipatch features. Browse to the location of the 3D model on disk you want to use. Click the 3D Editor drop-down menu and click Replace With Model. (Although the extruded buildings can be converted as a multipatch file and then to collada. Hold the Shift key to select multiple features. Click OK on the Export 3D Features from Target Map dialog. I don't believe ArcGIS has a default tool for "slicing" in 3D. Select the multipatch feature or features that you want to edit.
