How to create a hole with extra material around it as a repeatable element?

[pr.i.stmacodg]

Hi all,

I have an element that includes a hole with some extra material around it to make it stronger and serve to anchor whatever is put on the other side. This screenshot would make it easier to understand

I'd like to be able to put this element that both has some subtractive parts (the hole) and some additive parts (the ring on the other side) any place needed by doing some kind of copy/paste or as a body/element or some kind of repeatable item.
For now, what I'm doing is modifying a sketch and all the different extrudes to add the new holes needed, but it's really annoying to do so and even worse if they are in different planes.

What way is there to repeat this kind of pattern? TIA!

Hi , 

you can pattern feature OR you can made tow parts (one for the top "solid" and anther one for cut "void" and copy past them)

the file below (see the time line )

I presume Pattern will not describe your work.  A random Layout.

Most efficient workflow.  2 Extrudes, Hole - done (3 timeline icons per face)

Sketch plate with only boss circles, (copy pasted)

Extrude all full depth.

Extrude plate again without circles selected, settings for a top surface cut.

Hole > Counterbore, Set Parameters, Select all centre points in the sketch.

Blue sketch articles should keep you awake at night.

The issue is that I cannot very easily use a pattern. I'm creating a box and inside that among other things there will be a PCB for which I need to create the holes so I can attach it with screws but I don't see a clear rectangular patter or similar in the PCB.

I think the pattern kind of works if I do it element by element which is not the easiest, but if not, probably the second solution will do with the counterbore holes

Thanks both of you for your help!

This is a good application for Modeling with Component Bodies.  I created a component body for you boss and c'bored hole to demonstrate in the video.  I am also linking to a Blog Article and Video which explains the process further.  It is a little work to setup but once done can be used over and over in any assembly.  I am also attaching my Component model I used in the video.  It consists of two surface bodies used with the Revolve command.

Complicated and clutters the browser.  Ok for one or two....  Would you do that for 15 (with joints)?

This way does them all.

Just another way to do it, it may not suit all, you for example.

thanks a lot! I think that solves it. I didn't know about that option and seems to do the trick. I'll play with it a bit more
