Design Tables Proble

Design Tables Proble

Design Tables Proble

(OP)
Hi!
I want to know how to make extruded,cut features and pattern features parametric , so that I can use then in design table. For example I have a flange in which no . ho holes for bolts depend upon the flange size. Bur when I use circular pattern feature to generate the array, I am not able to control no of hole for various sizes. Can anybody give a clue?

RE: Design Tables Proble

There are several ways to do this, one involves formulas with respect to the no of holes in relation to the diameter. for instance if you have a flange that is say 200mm in Diameter and you wanted the number of holes to change as the diamter changed you could write a formula to drive the number of instances. When you create a component pattern in this case a circular pattern, it has two dimensions associated with it (number of degrees) and (number of instances).

You could write a formula like this:

"N_Holes@CirPattern1" = "Diam@sketch1"/60

in the case of a 200mm flange, the value of N_Holes would evaluate to 3.333333.  Solidworks will round that off and render an integer value of three.

Now any time you change the diameter, the hole pattern will follow.

If for some reason you do not have a set pattern for given diameter, you can simply bring the pattern dimensions into the design table and drive them that way.


hope that helps

Thanks Jon,
This has really worked. I was able to use an Excel table containing no of holes , extruded length , depth of cut etc.
