Compression

Compression

3D Viewer Export may be captured in one of two formats using the File Format drop-down menu:

GLB This is the default option: a GLB format file with Draco compression applied. This will compress data associated with solid, thick shell and shell elements (but does not compress the data associated with beam elements). It is slower to write and to read but the filesize is likely to be much smaller (5-10 times). Microsoft PowerPoint does not support this compressed format. GLB uncompressed This is an uncompressed GLB format file. Because no compression is applied, this format will be quicker to write and to read but the filesize is likely to be much greater (5-10 times). Microsoft PowerPoint supports this uncompressed format in PowerPoint for Microsoft 365 or in PowerPoint 2019 or later.
