the pattern relation

[Guest]

Hi! everybody:


when I create a holepattern, the first direction with a relation is :


memb_i =lead_v+idx2 (lead_v=40)


and the second directionincrease is a value (the value is 40),according the relation, the pattern increase must be equal value in every row(in the first row is 40, the second row is 41, the third row is 42 ...), but the increase value is degressive.( for example, the seventh row's increase value is 46,45,44,43,42,41,40,40,40....)


I try that in version 2001 wf1.0 wf2.0 and wf3.0, that is the same result.


who can tell me the resons? thanks!

Looks like ProE couples the horizontal values to the vertical values. The X-values on row 7 are base+7, base+6, base+5, ... As the position of the holes goes up down the line ProE adds the index values going down the line.

If the relation instead of : memb_v=(lead_v+idx2)*(idx1+1)


there are not problem.


the two relations is the same thing, but the result is different.
