Exporting two features with the same attribute value will result in the second exported feature overwriting the COLLADA file of the first. To ensure a new COLLADA file is created for all the exported multipatch features, set the destination directory to an empty or new folder and choose a file name field that is unique for each feature. A GP message is also generated for any features that fail to export-for example, if the output location is read-only, or the disk is full.
When this happens, a warning message is given stating which files were overwritten with a new file during the export process. This tool automatically overwrites any existing COLLADA files with the same file name. To minimize the total export file size, textures that are used in multiple COLLADA files-such as a repeated brick or window texture-are only exported once and then referenced by the applicable DAE files. Texture files are stored in the same directory as the COLLADA file. This allows easier identification of which feature was exported to which COLLADA file and also provides the methodology for defining unique names when exporting multiple features to the same directory. The tool uses a field value from each feature-by default, this is the Object ID-to define the output file names. This tool creates one COLLADA representation for each multipatch feature that it exports. dae file containing the XML representation of the 3D object and one or more image files (for example, a. This means that exporting a multipatch feature to COLLADA can result in the creation of several files-a. COLLADA files are an XML representation of a 3D object that can reference additional image files that act as textures draped onto the 3D geometry.
