@williamatics I’m currently analyzing your file. Basically, you make a smart use of reusing a small set of pieces and rotating it in order to make it look as if there were a greater variety of pieces. However, 68 planks with around 400.000 vertices for each object is really heavy even for very fast computers despite you using linked duplicates. Each of these duplicates occupies a lot of memory (around 2GB for all planks together). This causes an extreme file loading time as described by @theluthier above. I need to take a closer look into your file in order to understand what’s going on. I’ll try it with replacing the linked duplicates by object instances which are essentially “Empties” which are used to position a visual duplicate of the original object. This saves memory and hopefully helps avoiding the long file loading time.
