Add two sketch lines in the sketch that places your first hole in the directions you want to stagger (in this case, one line horizontal and the second line at 45°). In the Linear Pattern PM, select the horizontal line for direction 1, and the angled line for direction 2, then delete the 13th instance of the upper row.
Here is a summary of your suggestions along with my comments. ___________________________ Solutions 1:
This work, but too much time consuming to click on skip instance if there is more than 26 holes (50, 68, 80, 120 etc), this number of holes is very common in connector industry. ___________________________ Solution 2:
If I sketch two holes and pattern them. It will be deleted or skip as a pair and not individual holes. Thus my holes will look more like this o o o o o o o o o o o o o o o o o o o o o o o o __________________________ Solution 3 from Matt Lombard & Steve R
Since most of the connector will have different column and row spacing (usually multiple of 0.8, 1.27, 2.0, 2.54 etc), the angle would vary (I think, in my case the angle is not 45° but rather Atan of 2.54/1.27 = 63.43494...). Could someone be kind enough to send me ( firstname.lastname@example.org) a model of this procedure? I try many hours and the dimension between row and column is off. Instead of 1.27 & 2.54, I get 1.14 & 2.27.
1.27 (1.14) || o|o----- | 2.54 (2.27) o------
Since I don't know how to post a picture at a web site, I can send you a screen shot in jpeg format to whom ever interested.
I did see the new Wildfire II demo for Patterning feature. It's pretty neat indeed.
It looks like you used a 2.54 mm long angled line at about the right angle to set the position of the lower pin. It's much easier if you dimension the horizontal (1.27) and vertical (2.54) distances from the top end to the bottom end of the angled line, instead of trying to calculate the angle and length for the line.
Sketch this and use these as your direction vectors (make the two lines merge at their intersection ofcourse)
the small angled line can be dimensioned to represent your 2.54 up and 1.27 over.
also add a driven dimension of the length (this can be used to control the spacing along the second vector)
Pattern select the strait line for direction1 2.54 as the spacing 13 as quantity select the second line for direction2 and use the driven dimension as your spacing and 2 as quantity
instances to skip and select the last one in the second row.
Or use this method
and instead of skipping the last instance apply the pattern then select the surface of the hole or the surfaces of the boss and right click on them you will have the option to delete surface. Apply that and the hole is gone.
