Open ViewerWhy browser CAD tools?
Desktop AutoCAD costs hundreds per month per seat — overkill when you only need to convert a DWG, count blocks, audit layers, or share a link with an owner. Each tool on this page runs the same engine as our full viewer, tuned for a specific workflow with export buttons and panels pre-enabled.
Files parse locally by default. Use DWG to DXF before BIM import, run Layer Audit before client submittal, overlay PDF issued sheets against CAD source geometry, and measure spacing without printing scaled PDFs.
