CADProps Technical Notes

The supplier can open the model, but a component is missing, the expected feature tree has disappeared or the assembly cannot be edited as intended. These problems call for different remedies. Re-exporting the same model repeatedly is unlikely to help until both sides identify what information the handoff needs to preserve. Disclosure: This guide was prepared for CADProps, which provides CAD inspection tools. It describes a practical diagnostic sequence rather than a claim that one format or viewer is always best. First separate the editable source from the exchange deliverable Ask the receiver what they need to do: quote nominal geometry, prepare CAM, modify the design or consume manufacturing annotations. Then assign a role to each delivered file. For example, a native package may be the editable collaboration source, while a STEP export is the geometry snapshot for another system. A controlled drawing may carry manufacturing requirements outside either workflow. Identify the sam...

A useful STEP inspection ends with a decision another person can understand: proceed with the stated task, request a corrected package, or hold because a requirement is unresolved. A screenshot of a model and the words “looks fine” leave too much uncertainty for the next engineer. This checklist is for receiving teams reviewing nominal geometry before quotation, manufacturing preparation or design review. It does not establish that a manufactured part meets its specification. Disclosure: This guide was prepared for CADProps, a provider of CAD inspection tools. The workflow can be used with any suitable viewer and the recipient’s own CAD or CAM system. Start with the decision you are being asked to make Write one sentence describing the permitted next step. For example: “Check that the supplied Rev C bracket geometry is suitable for preparing a machining quotation.” That is narrower than approving the design, approving a manufacturing process or accepting delivered hardware. Next, ident...
