Thanks to Mr. Bence Frey, who spotted that the latest release of Analysis Situs has been compiled without FBX support (https://www.analysissitus.org/features/features_asm-xde-document.html#toc-asm-xde-save-fbx). This update fixes the problem. Upgrade if you need to convert CAD files to FBX assets (e.g., for Unity).
