3D CAD STANDARD
3D CAD STANDARD
(OP)
Hi all,
I am after references to any existing standards pertaining to 3D CAD modelling.
Basically I want to write a procedure for our company and thought that procedures used within the Aircraft industry probably exist and are of a high standard

RE: 3D CAD STANDARD
I have written guidlines/standards (call them what you like), defining standards to adhere to when drawing in 2D which details things like layer types/ text size dimensioning philosophy etc. What i havent writen previously is a generic 'best practice' guide for the 3D modelling environment. This would detail initial sketches fully constrained, setting formulas into all extrusions (to make it simpler for the next guy when editing required)
I used to have an old Airbus document that I think ws given to new designers detailing such things. I was just wondering if these are in the public domain

RE: 3D CAD STANDARD
Everyone kept bringing up ASME Y14.41 but this isn't what you're talking about, it's about MBD.
We wrote our own internal one, based on references I had from a previous employer and various ideas of best practice etc that we's picked up along the way, and we asked our CAD vendor about a couple of things.
The trouble with a generic standard is that there are so many differences between software that it's difficult to cover them all. Even though a lot of them share similar processes & functions etc. if nothing else terminology can be different.
You may have more luck just looking for something for your specific CAD package. I once saw a little guide called Unigraphics for dummies (freebe at UGS conference) which may be the kind of thing you're talking about.

Obviously this is biased to SE but at least some of it is applicable to other systems.
It's not an all encompassing standard but gives some ideas.

They want to be able to upload your CAD files directly into their database (typically via ftp) without any effort on their part. If you're a valued supplier to them, they will be more than happy to send someone out to help you get up to speed on the procedures they use with regards to CAD/CAE file preparation.
