It has an interesting mode of operation:
Our aim is to showcase professionally built models and allow BIM users to utilize them for their projects. Content is free to download by clicking on the image in each post and/or download link. The use of our Revit© content is open ended with but one restriction; selling the content in any manner is strictly prohibited. We advocate for the free exchange of file sharing with friends, colleagues, and classmates.
Relinquish Your Revit© Families
Millions of quality Families hibernate from lack of use on hard drives around the world, utilized exclusively by content creators and colleagues. We believe this information should be publicly shared to prevent the redundancy of work involved with individuals creating identical models for their sole use. Sharing your efforts and information will save time, money, and energy, and will result in a comprehensive and high quality resource library for all to use.
