Demtool Feedback

  • Consider the number of set-ups required to make a piece
    • Make blind holes through if possible
    • Ex. MR22-DT-P0116 (suspension)
  • Give them the part, then they will account for machining modifications
    • Ex. MR22-DT-P00027 is to be laser cut. We'll send them a step of the file with nominal holes, then they'll modify it to be cut undersized so that it can be reamed
    • Want assembly drawings and assembly STEPs to understand the context of a piece!
  • Can give some sort of note or way to inform them of non-critical features, i.e. clearance holes, unimportant radii
    • Put in a note or don't label it
    • Think of them as gauging instructions (for outsourced stuff), i.e. the dimensions we actually want to measure
      • If being CNC'd
