AutoCAD

AutoCAD files, blocks and hatch libraries for two-dimensional drafting. The collection includes block boxes, accessibility and sanitary sets, pattern libraries and starter kits with layers already configured.

The difference between a drawing that survives a project and one that becomes unusable is layer discipline. Layer names, colours and line weights should be decided once and applied everywhere, because every later operation — plotting, referencing, exporting to Illustrator or Photoshop — reads that structure. A file where everything sits on layer 0 in white cannot be plotted properly no matter how good the geometry is.

Blocks compound that discipline. A well built block is drawn at real size, carries a sensible insertion point, and sits on its own layer so you can control its weight without touching the walls. Blocks drawn on the wrong layer inherit the wrong pen and fight the drawing they were meant to serve.

Our guides to AIA CAD layer standards, practical CAD layering and title blocks cover the setup.
