Showing fasteners in aerospace Catia V5 assemblies
(OP)
I understand that we need to forget V4 when working in V5, but, it helps here to pose the Question.
In V4, to show fasteners in an aircraft assembly, I used dittos of a detail for that fastener anchored at a point and rotated to an axis at several locations (sometimes 100's of places). Modifing the one detail changed all its respective locations.
In V5, I've tried instantiating from a catalog. Each comes in at the origin and has to be constrained to each locations point and axis. The tree under the Product grows huge and the process takes more time when dealing with a large aircraft assembly rigged in space.
What is the preferred method in V5 to replicate the V4 process of 'rubber stamping' dittos using a catalog of fasteners?

If it is a part that actually has a quantity in the P/L, we instanciate it.
The only way that you could have moved all of the "where used" would be to have actually changed the part using Part Design. Moving an instance of a part within it's parent assembly should not effect any other assemblies. You had the same problem in V4 if you entered the workspace of the detail and modified something there.

the Flexible component works well. I instantiate a group of fasteners into the Flexible component and use the published axis and anchor point from the tree to locate each to the points and lines in space.
One other question for you. What's the best method to flip a fastener that comes in the wrong direction? If they were build in the catalog pointing '-Z', they will land on the surface generally in the '-Z' direction. If they need to point '+Z', I have to flip them. I've used the manipulate about a local axis with the 'Respect to constraints' off to rotate them around and then update, but, most of the time there won't be a convienient line locally to pick to rotate about.

Also, Flexible sub-assemblies work just fine until you are working with a VPDM system such as ENOVIA VPM or LCA. They aren't supported in either system :-(

In fact, most of our engineers start at the top level assembly for the aircraft, and then dive down the product structure to get to the parts they want. That way, they are absolutely certain that the parts are in the correct position relative to each other. With a sub-product, you never know if some translation has occured to a node above your current assembly level.

We were a VPM user with V4, so using VPM with V5 was the logical choice for us.

This 'Flexable' product works great for the fastener application. It keeps all the fasteners grouped within a node that can be calapsed, it can be read into another product, and you can leave them as cgm's for the graphics. So, will this cause us problems with data managers later? What's the options?
RE: Showing fasteners in aerospace Catia V5 assemblies
Other data managers that simply take the CATProduct Document and archive it may have better luck, although they may not support other functionalities.
There are always trade-offs. My personal feeling is that your data manager should come from your CAD vendor, as they will usually have the best support for the most features. Trying to use 3rd parties usually means a lag between releases and support of those releases.
