DrawMyPart

Drop a STEP file. Send a drawing your machinist can’t misread.

DrawMyPart checks your part for what makes it expensive to machine, asks you to confirm every hole and tolerance, then draws the sheet: views, hole table, notes and title block.

From model to shop-ready drawing

  1. Drop your STEP file

    It is read in your browser with OpenCASCADE. Your design is never uploaded.

  2. See what drives the cost

    Corner radii, stock size, odd holes, thin walls, setups and material, each with an estimated saving.

  3. Confirm every feature

    Threads, fits, counterbores, material and finish. The drawing stays locked until nothing is left unchecked.

  4. Export the drawing

    A3 PDF, DXF and SVG, plus a hole table CSV. Send it with your STEP file.

What the cost check looks for

The same things a good machinist would point out on the phone, before the quote comes back high.

Read the design-for-cost guides

  • Stock sizeA part 0.5 mm over standard plate pays for the next size up.
  • Inside corner radiiSmall radii in deep pockets force slow, fragile tools.
  • Sharp inside cornersImpossible to mill; they need EDM or a relief.
  • Hole sizesOdd diameters need interpolation or special tools.
  • Deep holes and threadsBeyond about 6× diameter, drilling slows down.
  • Thin wallsUnder 1 mm in metal, walls chatter and bend.
  • SetupsEvery side that needs work adds fixturing time.
  • MaterialFree-machining grades can halve the cycle time.

Your design stays on your computer

The STEP file is processed in your browser. Nothing about your geometry is sent to a server, which keeps confidential designs confidential. Only your account and payment status are stored.

A drawing that says what the model can’t

Your shop programs from the STEP file. The drawing adds what the model cannot carry: threads, fits, tolerances, finish, material and what will be inspected. DrawMyPart puts each of those in its place on a standard A3 sheet.
