I am a complete novice to 3D. I am trying to downsize a file of a train engine that is 400+MB so that I can import it into Adobe Dimension for a layout. Currently the file is too big to be used practically.
I've tried Decimate but I know I'm doing something wrong because I can only get one section to downsize, not the entire train. I've tried eliminating the hidden polys, but no luck there either.
I get the files from a third party (not sure what software is used originally), then an engineer converts it from either STP or IGS to OBJ. If anyone knows a better way to achieve a smaller file, it would be a great help. Thanks!
