@pbacot - I copied everything and pasted into new drawing. Something in that original drawing was messed up, but because it wouldn’t let me pan or zoom or even right click, I couldn’t tell you what went wrong.
@Monirfaizi - I can tell you what is wrong with your model now that it’s been copied into a new clean drawing. Firstly, 103 mb for a single floor plan is a veerrry big file. It’s due to the furnishings you’ve chosen. Most seem to be high poly components for rendering. Did you find them from 3D warehouse? Just the desk I’ve selected here is over 80,000 polygons and that’s just one component. The whole model is at 2.8 mil which is very high and tends to start to cause lagging. There are also a lot of layers. And I’m sure that not everything is drawn on the proper layer. And there is loose geometry that should be grouped like the walls, windows, etc. So yeah, a lot that can be improved here. Good luck!
