    Fill pattern style (help)

    ChristianSmith Bronze

      I've never used the fill option when creating a pattern and maybe this isn't even the right function that I trying to accomplish, any help would be great.  I have a ring and I want to pattern a cut round, around the ring.  I can figure out how many will fit and enter the quantity of instances to pattern and the angle.  However is it possible to use the fill function or something similar so that pro/e will automatically calculate how many instances will fit around a given surface?

      Here is a picture to help you understand.  In the image I have two dimples that are grouped together and then patterned.

               Could you enter relations that would figure the circumference of the circle and divide that by the diameter of your cut (+ any space you would like for a minimum) to determine the number you will need, and then use that number to define the quantity of cuts around the ring?

            Christian,

             

            You can do this easily with an Axis Pattern.  Fill Pattern is not what you want.

            After telling the system how many you want, be sure to pick the little angle icon (instead of entering a value), and the system will do the rest for you.

                David:
                The axis pattern is what I've been using.  It is nice, and gets the job done, it just requires a lot of guess and check.  If this is the best method so be it.  As for the relations with the outer diameter and the diameter of the diameter of the dimple I'll give that a go. 

                Thank you both for your input.

                    Yeah I think that the answer to this is a combination of mine and David's.

                     

                    Use relations to determine the quantity required and then assign that number to a integer parameter, and then create your pattern as David described. After creating the pattern, you should be able to add a relation relating the number of instances to the integer parameter you created.

                     

                    Should be magic after that.

                  There is a way to make this with fill pattern but you cant avoid using relations. First you must create sketch paralel to object. Lenght of that sketch must be equal to circumference of ring so when Creo/Proe wraps pattern on to surface of ring it covers entire surface.

                  And last you must deal with overlaping of pattern items by using simple equation. Down side is you must add *cos(45) or remove it depending of type of fill you are using.

                  Good side is changing ring size  or changing number of pattern items gives quick results.
