rkent Posted September 22, 2009 Posted September 22, 2009 I have been trying to find the best way to do this in IV. I have been using two rectangular patterns and suppressing the holes that run off the edge but that gets tedious. Any better ideas? Quote
Raggi_Thor Posted September 22, 2009 Posted September 22, 2009 If you don't need to count the holes, maybe it's easier to "fill" the holes you don't want with one new sketch and one extrude? Quote
shift1313 Posted September 23, 2009 Posted September 23, 2009 Inventor 2010 has a feature used for this but i havent tried it yet(and dont have it in front of me). Something like Vent. I believe you can select a sketch as a boundary and a sketch as the cut out, but again i havent used it yet, this is how it works in other programs. Looking at the pdf i see 16 quandtrants of the same thing. You sould only have to lay out the circles in the first 22.5 degrees and do a circular array. Quote

Thanks, I have now tried the Grill command but I have not figured out how to make it work for this situation. I will try the 16th quadrant idea and see how that works. I was hoping I could make this a more parametric part by changing the size of the holes, the spacing of the holes, the inner and outer boundary where there should be no holes. Do you know if the other solid modeling programs can actually do this? Quote
shift1313 Posted September 23, 2009 Posted September 23, 2009 I have drawn similar parts before in the past and i have had to use the array and exclude method. Its not too bad when you can do mass selections. If you draw one quadrant and do an array(after you subtract the holes) 16 times you should be able to adjust things as you wish. Just make sure in your sketch that all the holes have the equal constraint and you will only have to change the size of 1 of them. And make sure your sketch is fully constrained and that the holes have driven dimensions. ill try this at home tonight with IV2010 but all i have here is an older version. Quote
