Transferring Fastener points
Transferring Fastener points
(OP)
I have an assembly in catia with parts exceeding 25. All these parts have their fastener points marked by means of points. Now I need to transfer all these points to the main mating member in the assembly. What is best and the efficient way to do it. One requirement the solution should comprise of is, when the part is relocated by giving some other co-ordinate values the points should also move.

Good luck to you.
RE: Transferring Fastener points
I suggest:
1. publish all the points
2. copy the publications in the parent part (you can select all of them if you want)
3. in the mating part, use Paste Special + Paste With Link to transfer the points
(I'm assuming both parts are using the same origin & axis system)
RE: Transferring Fastener points
All depends on company method/procedure...usually in aircraft industry each part (with some exceptions) has their own origin not a common one so they can be reused in many different assemblies (for example brackets reused even in different airplanes...).
That's why you don't want links (sorry jackk, this time I have to disagree with you, I saw that xcllyf is in Aerospace industry) ...in many companies I saw those fasteners points in separate parts or components (in assemblies).

RE: Transferring Fastener points
The reason for my suggested approach was as ferdo noted. With a product composed of one or two parts with several fasteners installed in holes in the parts, you normally want to constrain the fastener to the part. I do heartily agree with your suggestion to publish the fastener features to be used for assembly constraints, and this is common practice in industry. For example, a bolt would usually have the body axis and underhead face features published. But as ferdo noted, if the point copied into the main part model was linked back to the fastener part model, the only way to modify the position of the point in the main part model would be to modify the position constraints of the particular fastener instance in the product the point is linked to, and then go to the main part model and update it. While this is possible, it is backwards from how CATIAV5 is designed to be used and how most PDM systems function.
Another thing to consider is why CATIAV5 has the published feature function. In large engineering departments that use CATIAV5, the designer responsible for producing and releasing the CAD model of the part, the fastener, and the product are usually not the same person, and the models are often released at different times. Due to configuration management requirements, once a part or fastener model is released that model file is locked down, and often the only features of a part or fastener that can be selected for applying positional constraints in a product are published features.
While this approach is not the only way to accomplish what was asked about in the OP, it is industry practice, so it would seem like a good idea to use it.
