cad blocks.

Check CAD blocks before using them in a drawing

• Confirm the supplied format and the CAD version you can open. Import a copy into a test drawing before adding it to a live project.
• Measure a known dimension and check insertion units, origin, layers, lineweights and external references. Do not infer construction dimensions from a thumbnail.
• Keep references separate from your own issued drawings. Verify project requirements and source permissions before adapting or sharing a block.
