It looks like you have some objects in your project that have very many polygons. Go to Help > ArchiCAD 16 Downloads and download the Polycount add-on. After installing the add-on, open the Polycount palette and see which elements have many polygons. You may need to adjust these elements or move them to a hidden layer.
You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.
