These 3D drawing files are currently available in .igs or .x_t format and can be downloaded by engineers, contractors, and others involved with project design from our website. Once downloaded, our products are then added to the project’s BIM design. If you are having trouble viewing these BIM files or do not have access to BIM software, we recommend uploading the .x_t file format to: https://360.autodesk.com/viewer. We have found this website functions best in Google Chrome.
With the increasing popularity of these models, we will be adding the .rfa format of these files soon.
