array of hole along sketched path

[mkirby]

Well ive seem to hit another wall and im hoping someone can bail me out once again. Attached is a part that i am trying to array a feature (hole) along a sketched path. Whenever I try execute the command it shifts the arrayed features over a bit as if i have an origin off somewhere. Im baffled by it. I did import the "path" sketch from acad geometry but I cant see why that would cause problems. I get many acad drawings of parts that i tool off of and I cant see redrawing all of these profiles just to make this work. Thanks for helping a rookie out 🙂 well the site wont let me attach an ipt so i will attach a jpg of the screenshot.

If you zip it up, it does allow. Sounds like it's a small file. Please attach the file. Thanks.

This what you are looking for?

The reason you are seeing an offset is probably because your original
hole does not coincide with one of the line endpoints of your sketch.
Use a line endpoint instead as your hole center.

This is prolly something that should be fixed 😃

There are a couple of tricks to learn in doing feature patterns. Once you know the tricks it is pretty easy.

Without looking at the file, I can only guess. Based on the preview, it
looks like the source hole feature is not located at the origin of the
sketch path. Unless you move the origin of the sketch path to the center
point of the hole, this behavior looks correct.

I honestly don't know if I would really call it correct.

What if you have multiple patterns that all use the same path, but may
need to start at a different location on this path? At that point in
time it is impossible to have them all located at the origin.

The way I see it, if a feature starts on a path and is patterned with
this path, it needs to stay on the path and not be offset just because
its not located at the origin.

You can define the start point.

I didn't even know that 😃

I always forget that autodesk likes to hide half the options in that
bottom pane...

Learn something every day...

Hello !

I am trying to do something similar, and hitting a wall I think.

My objective is to drill holes along the outer wall of the part [attached here] and I am currently approaching this by first projecting a 2D sketch from the outer wall edges on the correct work plane (which is offset from the top face by a fixed distance), then placing a work point in the mid of the path, and next creating a rectangular pattern along path using the work point and the sketch, choosing mid-plane option to position the points along curve length.

This is where I can't progress anymore. The Place hole feature requires me to provide a point and axis, which I place for the central hole. But all other points are along the curve, and do not have an axis through its face normal.

Placing individual work axes is an option I tried, but then the holes need to be placed individually too. Is there something I could do to make the holes pattern follow the surface normals at the points of placement ?

Thank you, in anticipation 😉

Something like this?  (see attached)

[akashkalyani]

Exactly like this. Thank You  !

My previews for the pattern always come off to the side of the face, for some reason. This threw me off even when trying to understand your solution.

But the holes themselves are correctly placed on the external face.

Thanks a lot for helping me out ! Cheers.
