Autodesk Inventor square flanges

I've seen a lot of different ways of creating bolted square flanges. This is one way I prefer to use :

Draw a square sketch and let the hole pattern fill along the sketch. Now you can easily insert one set of bolt, nut and let it follow pattern.

Create a sketch for the first hole




Create the pattern path and dimension it




Create the first hole







Turn on the sketch to access the pattern path








Select and decide holes in the pattern. Remember to select clockwise direction. Also remember that the number of holes must be dividable by number of sides. When finished turn off the visibility in the sketch.(re : pt 4)






Mark the first hole for the next person that opens the part. It’s good practice to mark the first hole in the pattern to use this information in further work.

Select the hole ,  rclick and select properties. Select a color to get a visible difference.




To prosper from the pattern when inserting components :

If we have two plates assembled like this, insert Bolts, washers and nuts in the first hole of the pattern.






 Select the inserted components and select rectangular pattern. Use “Feature pattern select” and select the pattern.  Now you will fill the pattern with the components selected..




If you now go back and change the number of holes in the pattern, the number of components inserted will update accordingly
