I was using AutoCAD Architecture AEC Space objects to mark up a site plan with hatched areas for parking allocation (below left). All was going well until, in the middle of an edit, they all changed appearance. Instead of colour coded hatch they had become a simple yellow outline (below right).
First thought was maybe some sort of display system problem (memory, resources, driver?) or I had changed display modes. The correct Medium Detail display was current so couldn’t blame that. A file open close, then AutoCAD restart eliminated potential memory/resource/system problem but the strange display persisted.
A trip to Display Manager (why didn’t I do that first) revealed the cause as it showed the “Model” configuration was being displayed instead of “Plan”.
It seems while toggling the active selection - with shift/control - and panning with the mouse I had, very slightly, orbited the model. It was so close to “Plan” that it looked like the plan but had orbited enough to invoke Model (3D) Display mode!
As these spaces are never used in 3D the Model display setting on all was the default byblock/outline only. Resetting the Plan view magically restored the correct appearance in a click!
While “Spaces” are intended for rooms I find them very useful for general hatching as display styles make controlling appearance of multiple objects easy. Just make sure you don’t accidentally fly into orbit!
