Because DWG 3.0 relies on delta syncing and WASM, it actually reduces storage needs, but it increases CPU threading demands. A dual-core laptop will choke on a DWG 3.0 file due to the real-time parameter calculations.

Autodesk has hinted that the true power of DWG 3.0 will only be accessible via their cloud platform (Forma/BIM 360). If you want the "Git-like" versioning and AI search, you must pay a subscription. You can't just buy a perpetual license and save a .dwg to a USB drive anymore. Part 5: DWG 3.0 vs. The Alternatives (IFC, DXF, STEP) Critics ask: Why do we need another DWG? Why not just use openBIM (IFC 5.0)?
The engineer of 2030 won't draw a line; they will define an intent . The contractor won't measure a PDF; they will query a model . The building won't be handed over as a stack of prints; it will be handed over as a —a living digital record that breathes alongside the concrete and steel.
DWG 3.0 will likely open DWG 2.0 files (automatic up-conversion), but saving a DWG 3.0 file back to DWG 2018 format will strip all intelligence. It becomes "dumb" vector geometry again.
