Hi Dalbeer...
I can help you with this. Some of the newer fill tools are much nicer but I can still dig up information on the pattern relations. Before the fill tools were released, pattern relations were the only way to go if you wanted to create a complex pattern without manually locating all the features.
With all due respect to Vladimir...don't waste your money on books. I'm stirring up trouble saying this but these books are nothing but a cash grab. They're glorified help files. Anyone with a bit of time to spare can go down the list of features in Pro/E, write a two-sentence blurb about each of them, and call it a "book". Most of these books don't do much beyond repackaging the same lame information the free PTC help files already give you.
The books don't teach you when to use the different features or why. They don't spell out the trade-offs and help you really understand when to choose one feature over another. Often it comes down to design intent and what you're trying to achieve. No book really captures this. If anyone DID try to capture this knowledge in a book, the book would be thousands of pages... and no one would read it.
The best way to learn these tools is to read the help files, ask questions here and other free sites, and investigate on your own. If you really want to learn all about pattern relations, I'll be happy to teach you what I know. The image below shows a d-subminiature connector with a pattern or pins created from pattern relations.
Do you have an idea for a specific pattern you're trying to create... or do you just need basic general information? Let me know and I'll try to help.
Thanks!

i do need help in this and if u plz look at the pic given below
this is a soap tray, I made an curve pattern and then select that pattern to make an axis pattern.. Now wat i want to do is to keep the equal desired distance between bottom holes even if i change its angle, pattern instances or curve patten instances...
and plz do give me a basic tour of relation pattern too.
thanx for ur quick replies Brian...
it the first option that u mentioned i need equal diatance between holes plus this thing to figure out how many pattern on curve can be patterned while maintaining the minimum hole-to-hole distance. i hope it makes clear...
let me tell u one thing more my english is not that good.. but hope i made it clear to u. 
Wow Dalbeer...
If this is even possible, it's going to take a good bit of pattern relations to accomplish. I believe I'll need to use your curve to perform some analysis that lets me derive the appropriate spacing. then I can apply those values to the pattern... I think.
I'm still not completely sure how automatic you want to make this pattern. I can make a nice, even pattern to fill in the area with holes... but varying the curve, angle, spacing, and hole size gets tough. Maybe you can convince your employer to settle for a nice spiral? It's much easier!
You will not be able to use pattern relations with an AXIS pattern. So we'll have to make a dimensional pattern which relies on the dimensions of the hole for it's variance. So far, I've managed to duplicate your pattern using this technique. It's quite a bit more complex to start tweaking the variables while having Pro/E automatically figure out the proper pattern.
I'll keep working on it.
Thanks!

just came up with a new solution but 
hv to go to skt mode to increase or descrease no of holes.
use parameters for patterns but it's not in fill pattern agian i use axis pattern with some relation if its possible in fill pattern will be great cause i can edit dynamicaly in one single feature..
Hi Dalbeer...
Let's jump right in. I hope this gets you where you want to go... click the slides for larger versions so you can read the text. I'll try to upload the modified model in a separate mesage.
made a little change in slide one... it will keep patten in controlled limit and geomatry. added an outer limit cicle and divied the curve into two.
awsome presentation!!! good solution.. thanx
but can we do it in single feature.. so that we can see changes dynamicaly??? i'm still working on that...
i'm not aware of relation pattern if u could share how that pin work is done 
u mentioned here earler it might help me
Hi Dalbeer...
Performing this type of pattern in a single feature (meaning a single pattern) would be tough. I'm not sure it's impossible but it would be significantly difficult. I'll go through the pattern relations as promised in the next reply. If it seems like I'm avoiding it... you're right! It's like giving someone a tour of a swamp... you'd rather not give the tour because it's not very exciting, the swamp is smelly, and in the end there are very few good reasons to go there in the first place! I can tell you're still interested though so I'll try to explain it.
As for the problem at hand... your best bet to see "real time" results is to figure out a clever way to use a sketch to drive EVERYTHING. Then you can vary the sketch in real-time using the Dynamic Edit feature. I've modified the original curve sketch in the image below. I've replaced the need for the min_distance parameter by adding it as a dimension in the sketch. I added the different sketch components as CONSTRUCTION items so they wouldn't damage the curve trajectory. Again click the slide for a larger image...
You'll have to substitute the dimension from the sketch for the min_diameter parameter in all the relations but this is easy. Once you've done this and regenerated successfully, you can use the Dynamic Edit tool. Select the sketch and right-click to select Dynamic Edit. Drag the handles (or modify the dimensions) and view the resultant geometry as it updates in real time.
I produced a very brief video on Dynamic Edit which might be helpful. It's up on YouTube here:

I'll go to work on the pattern relations primer next...
Take care!

pattern failed all the time....
Hi Dalbeer...
I'm trying to figure out a coherent way to show examples of the pattern relations and how to control them. It's a bit more challenging than I thought. Here are the first seven slides of the mini-tutorial. This is basically just setup work showing how I created a simple model. It also starts to explain the various special parameters at work in pattern relations. The next set of slides will show examples of how I used those special parameters to create a bunch of different patterns.
Stay tuned... sorry this has taken so long. I don't like doing a half-baked job when I am trying to put together a tutorial. I feel most tutorials... even the better ones... gloss over numerous details in the interest of keeping the tutorial brief. But in doing this, some of the usefulness is lost... some of the meat of the feature being demonstrated is lost. Pattern relations have been a black hole for a long time. They're rarely discussed and few books and tutorials bother to explain them.
Maybe this will help change that. I'll put everything together in one document when I'm done. You're a sharp guy... you'll be able to figure this stuff out in no time.
Here's the first few slides...
... more to follow with examples of controlling patterns using these special parameters...
Hi Dalbeer...
Here are the next set of slides. I'm trying to explain HOW the slides are attempting to explain pattern relations. If anything is unclear, please let me know. Once you understand how the first example is constructed, the next several examples will be constructed the same way. I'll show the relation, the original feature, the values generated by the relation in table form... and the final result.
If this layout isn't clear or you don't get what I'm trying to say, please let me know so I don't move forward until you understand.
Thanks...
Here are the next fews slides...
... more to come... please comment so I can insure we're on the same page!
Thanks!
