assembly holes
assembly holes
(OP)
In real life and most (if not all) other cad systems, you can stick parts together in an assembly (eg. a weldment) and then drill ONE hole, ONCE, through all of them. Why can't we do this in NX? Having to promote or wave link the parts, then put separate holes in each of them, then type in the right expression if we want the hole sizes linked, and only being able to dimension each hole off of its own solid is ridiculous. Holes get match drilled all the time, so we ought to be able do the same thing in the cad system without it being such a nightmare. We have over a thousand seats, and I hear this same gripe all the time. The assembly cut feature is at least a start in the right direction, but we finally got a good hole wizzard - we should be able to use it on assemblies. How about if there were something like a macro that runs the hole wizzard then makes a solid that "assembly cuts" through all the parts? Anybody have any ideas?





RE: assembly holes
If you are on NX6 or higher, look up 'assembly cut' in the help files.

Maybe wait until John Baker gives his two cents worth . . . there is a good answer for what you want.

I am in NX6
RE: assembly holes
Thanks.
RE: assembly holes
The best solution would still be to fix the software so you can make a hole using "hole", just like in a piece part. Maybe I can run it up the flagpole here and we can get it considered as an enhancement request.
RE: assembly holes
Not on NX6, so hopefully Siemens has fixed the Pro/E problem of modifying the details with the cut hole. The cut is only at the assembly and should not modify the original parts.
I know promotion of bodies has been replaced by newer tools, but you could do assembly cuts in V13, if I remember right.

...and create a Hole using Type 'Hole Series'.

RE: assembly holes
'Hole Series' is handy if you want holes in the piece parts, but that's the problem here; when you're drilling at assembly, you don't want to see the holes in the individual parts. I tried suppressing it at the part level, but then it doesn't show up in the assembly.
There is, however, a relatively happy ending to this saga; I think I've found the least painful way of doing it. You can promote only the first part the hole goes through, and put in the hole just like normal, except down toward the bottom of the dialogue, in the "boolean" box, pick "none" instead of "subtract." Instead of making a hole, it makes a solid you can use as a tool to make your hole. Then do 'assembly cut', pick all the parts you want to drill through, and pick the "un-hole" as the tool. Bingo, you now have a hole wizard hole, through however many parts you like.
RE: assembly holes
There's been discussion of the non boolean option before here as well. I guess it works as well as any method. Another way to deal with those kinds of problems that many people use is to simply state drill on assembly on the drawing. I also understand why some people don't follow that process, but it is there as an option.
