does anybody know a tool or add-on for NX to do reliable wall thickness checks?
We use all major CAD systems and for those integrated add-on`s are available (e.g. GeomCaliper) which give out a check list with all the questionable wall thicknesses.
That way you cannot miss problematic areas and a visual check for e.g. cylinder heads does not give any reliable results.
Also generating a report for release documentation is also very useful.
I`ve heard of DFMPRO but as far as I understood it is for injection molding.
It is only available in NX when installd additionally.
Do you have it available and can it create a wall check with a list of results?
DFMPRO has all kinds of checks assemblies, sheet metal, tubing many many more different checks . I will run an example and show some screen shots. This runs in checkmate. This was ran on a simple box. I have attached some images of run I just did. Very simple but powerfull. You can set the wall thickness limits in a file called a rule file. So you can set your min wall thickness and max wall thickness. Depending on what you are modeling. It is a nice tool to check your models and assembly with.
We use the moulded part validation tool on thin-walled castings, and I believe it's pretty reliable. You need to buy an additional licence to run it (obviously), but it is at least all contained within NX rather than having to manage a separate program.
you would need DFMPRO to get these checks.
I cannot show you where they are or how they work since we did not acquire the DFMPRO license.
I would recommend to contact DFMPRO to get a test license/price.
