Duplication of a circular pattern

m.konopacki25 — Fri, 02 Jun 2023 20:27:28 GMT

How do I duplicate those two circular patterns down the cylinder around 40 times?

Do a Rectangular pattern and pick the circular pattern to duplicate, then add the cylinder axis as direction 1.

This can be done in one pattern.

So the pattern needs to go down until the circles reach 166mm as shown in the attached image. Also, I just realised that the holes aren't hollow so that pattern also has to have hollow holes.

You can make one pattern and then delete the excess faces, or you can make separate patterns for each circular pattern.

Feel free to experiment with the number of repetitions as you create the pattern to see the effect.

@m.konopacki25

Your sketches are not fully defined?

What happened to diameter dimension in Sketch3?

Why did you use Emboss rather than Extrude?

I was following a tutorial of a guy doing patterns around an Ikea lamp and when he used emboss, the patterns were hollow so I thought my patterns were hollow but I only realised they were not hollow when I finished my second row of circles.

@m.konopacki25

How will the holes be made in the real world?

Will they be made in flat material that is rolled into a cylinder?

What is the link to the Tutorial that you were attempting to follow?

Emboss is good if you want to do it on a 3D printer, or a tubular profile cutter, or a 5-axis CNC machining.

If you want to do it on a milling machine or CNC machining center using drilling, Extrude operation would be better.

Either way, the selection of the feature does not affect the depth of the cut. The depth of the cut is defined inside the operation (in the dialog box).

I don't know what machinery it will be made with yet but it will go through a prototyping stage and I will use a 3d printer for that. Also, it will not be made in flat material rolled into a cylinder but from a purchased pipe with the correct thickness and close to the correct diameter.

Hi! I vaguely remember we had a bug in 2023 RTM build. Please install 2023.3 update. The issue should have been fixed there.

Many thanks!
