What is a proposal in Blake?
In Blake a proposal is a value from the drawing, such as material or roughness, that stays pending until someone confirms or corrects it.
Proposals cover material, general tolerance, roughness, finishing and thread. A proposal is not yet a requirement. It becomes an established requirement once someone on your team confirms it or corrects it to what the drawing actually specifies.
How does a proposal work in practice?
The drawing of a stainless flange says 1.4404, for example, while the proposal says 1.4301. Anyone who checks it against the title block and views spots the difference and corrects it. If a value like that is accepted unchecked, the estimate rests on the wrong material, and the mistake only surfaces at the material certificate, in a material analysis or at the customer. Because 1.4404 contains molybdenum and is usually dearer as bar or plate, the material price in the estimate can also come out too low. Checking usually takes less time than retyping: you compare and decide per value. On a repeat part at a new revision you confirm the unchanged values quickly and focus on what changed.
What is a proposal often confused with?
A proposal is not a confirmed requirement: a requirement has been established by a person, a proposal is still waiting for that. Nor is it an estimate: an estimate is a calculated time or amount in the costing, a proposal is a value taken from the drawing.
How do you see a proposal in Blake?
Material, tolerance, roughness, finishing and threads sit as proposals with the part in the request. You confirm or correct them; who did so and when stays visible, with a note if you add one. More on requests.
Frequently asked questions
Do I have to confirm every proposal separately?
You decide per value: confirm or correct. That way every requirement has a name and a time against it, and you can see which values nobody has reviewed yet.
What do I do when a proposal is wrong?
Correct the value to match the drawing; the correction is recorded with name and time. A note is welcome, for instance the view or section where the right value appears.
