The cloud is woven into the tool like a second hand — present and practical but not conspicuous. Collaboration loses its awkwardness: versions reconcile with a diplomatic patience, multiple disciplines converge in a shared space that is less a battleground of files and more a common studio. Issue-tracking lives inside the model; comments anchor to geometry, to design intent, to decisions that used to drown in email threads. When consultants touch the model, their edits arrive with provenance and explanations, like handwritten annotations in a bound sketchbook.
