There currently are 3,859 3D models ready for download in the 3D ACIS file format on the marketplace. Feel free to browse the collection and do not forget to use the other search filters to find PBR, rigged, animated or printable 3D models for your projects. If you’re a game developer use the ‘Poly count’ filter to view low-poly 3D models which need less computational power to render. The majority of 3D assets on CGTrader are available in several file formats, and if a model you want is unavailable in the 3D ACIS file format, you can always ask for a file conversion by selecting ‘Request free file format conversion’ on the product page. You can also visit our 3D Jobs page and post a request for model conversion, custom models and any other modeling services you might need.
