Definition of Design Intent
Definition of Design Intent
(OP)
Hello everyone!
Does formal definition of a term 'Design Intent' exist? I'm interested in the version of it that is related to the parametric CAD models. I found it hard to find a strict definition, perhaps because it is considered a universal knowledge.

It's just that some software lets you type in formula instead of raw numbers. Formulas are more expressive of a designers intentions. "(dist5-dist10) + 0.005" is more descriptive than "2.995" and might give a clue about why the designer made it the way they did.
It's just a description of an idea. It's not a technical term with a verbose and enlightening definition.

"Design intent is how your model behaves when dimensions are modified.
An example of design intent is how you create and dimension a hole in a block. The hole can be a certain distance from a corner or edge, or it can be in the middle of the face, for example. If the size of the block or the hole changes, the part rebuilds correctly if the design intent has been considered in the definition."

I think most of us know what is meant ... the machine was designed to perform some operation within some parameters.
As for a definition, I'd look to some contract language that uses the term.

There's lots of fancy stuff that CAD can do to help with the initial design that the trainers from the CAD company will say is capturing design intent etc. but then when you get to the point you need to lock it down for production can come an bite you in the a$$ for future maintenance of the design.

Think about context. I never heard the term "design intent" before I got trained on 3D CAD. It makes sense. There are many, many way to parametrically model just about anything. In a design process in which the final part configuration is uncertain, you have to make decisions, and you anticipate changes. For example, in a sheet metal part, I am likely to change the material thickness. Any model that cannot cope with this, is bad. Part of my design intent will be to use the same thickness of the same material on each and every part of the assembly.

as it happens there are several meanings ... I'd've never considered the 3D drafting meaning, but it's there if it helps !

I propose the term "design intent" is what the "chair farters" refer to when they have a completed GOOD part.

To the Toolmaker, your nice little cartoon drawing of your glass looks cool, but your solid model sucks. Do you want me to fix it, or are you going to take all week to get it back to me so I can get some work done?

RE: Definition of Design Intent
No one intends parts or mechanisms or systems to fail to meet specifications, so nothing meets design intent.
For the most part, it is a vague term to bolster an argument when drawing interpretation is being made by someone who can't read drawings or (less frequently) when the drawing is not clear. But that is why a clear specification is better; no guessing what the 'intent' might have been.
RE: Definition of Design Intent
When we talk about "design intent" that way, we usually manage to narrow the discussion to consideration of just one of those considerations (strength, etc) at a time - guaranteeing us something else to talk about the following week.

I have yet to find a satisfactory solution to this issue although I do try and give an explanation up front and in the case of Catia try to have the originating 3D model sketch reflect the final drawing dimension scheme.
