Best CAD Drafting Practices
  1. Do not show too much details. Too many details can overcrowd the drawing and be just as bad as not showing enough details. Show only what’s needed to properly illustrate the drawing or detail per the given scope, asset, structure, equipment, etc.
  2. All drawings should complement each other. Do not show repeat information on duplicate drawings. This can become confusing and create havoc on performing drawing updates and modifications.
  3. Do not use too many dimensions on drawings and details. Use only the dimensions that are needed to properly illustrate drawings and details.
  4. Be careful when exploding details. Some details & templates may be comprised of a thousand pieces and exploding a detail may create havoc on your drawing. Many times its easier to remove the detail from your main drawing to explode in another drawing session and then copy and paste the detail parts you need for your main drawing.
  5. Create good CAD standards. Use proper layers for various disciplines and various equipment/layouts, etc. This saves time when needing to freeze or turn-off certain layers for particular objects, disciplines or layouts. Also make sure line weights and text sizes are proper weight and sizes with same font and standardized throughout all the drawings. Uniform is the “key”. Use standard plots with proper plotter pen weights, etc.
  6. Create Standard CAD Details & Templates. Using standard CAD details and templates will prevent re-inventing the wheel each time by not having to redraw each detail or object. Simply insert into the drawing to save time.
  7. Verify you have shown the proper scaling and measurement units on your drawing(s). Many times its easy to get confused between inches and centimeters or feet with meters. Double checking that you start out with the correct scaling and units will save time in the end.
  8. Check and Review your design & CAD work. Check your work on the screen before printing to save reprinting if a mistake is later found. Always check and review your work, including: spelling, layer settings, line weights, text sizes & fonts, dimensions, measurements to scale, revision circles, revision notes, miscellaneous details, drawing clarity, etc.
