Triangular patterns

[Anonymous]

A question for the collective experience here. see my pic of a PITA part. The holes are in a pattern but to make it work I have to suppress a ton of occurrences in the pattern  to make it fit the triangular part.

Is there an easier way, I can post the part but it is based on a skeleton part

Thanks for any help

I ran into this recently and there were two different methods suggested. One was modeling based and the other was programming based. Read through the thread below and you can see what was suggested. Also please vote for the idea to have patterns inside of boundaries as a feature in Inventor, there is a link in one of my replies.

Unfortunately there isn't an easy button for doing this yet.

Before I make up an example, what version of Inventor?

I would have preferred that you gave me a file to work with - but perhaps the attached will give you some ideas.

Pull down the red End of Part marker, step-by-step.

Just keep in mind, if your not familiar with patterns you can utilize a feature based pattern in an assembly to fill all instances of these holes with an item. But with what JD attached, it will also fill the holes out in space that were cut away. Just keep that in mind for the assembly portion.

Thank you very much.

The delete face did not work with my part, perhaps because it is sheet metal.

But I simply added a face over the offending holes and it was great.

There is nothing special about sheet metal.

My guess is that you did not checkmark the Heal option.

Checked the box and it worked like it should

Thanks again
