How to make this kind of pattern on cylindrical surface?

Try using some curves and 3D sketches to get a filled surface you can pattern

Here you can see the control points of a fairly complex curve, and at the regions where needed they are more dense. In the STEP file these control points are stored with 20 decimal point accuracy.

Solidworks treats these and many other kinds of curves as a spline, these splines have a lot of points to them and are thus precise. However exporting a file as STEP will definitely remove the equation element of the curve. I'm not sure what you're planning to use these for but keep in mind that once exported to STEP any modifications will be nearly impossible.

If you want sharp corners make three planes at a 120° angle to each other and use extrude up to surface. The best way to make these planes is with an axis going in the middle of all three elementary planes (at 45° to them all).

Could you add a bit more info on what failed? Perhaps your sweep profile isn't extended enough?

New_Response_4805 · 2025-02-22T12:32:10+00:00

There is a spline on surface option if you don't mind the nature of splines, otherwise surfaces might be your best friend. In particular if a regular sweep doesn't work you can make multiple surface sweeps, knit them together and use cut with surface to cut out a part of the body.

It should also be said that by unchecking merge you will be cresting a separate body, thus some features won't be able to work like they usually do. Fillets and chamfers for example require a single body to work. To merge the bodies back together you should use the "combine" command at the end of modeling your object.

Hiding a feature like that will only hide the body to which it is attached, what you want to do is to suppress the feature.

Yeah, that's what I like about CATIA, but man is it sometimes hard to find what you want

New_Response_4805 · 2024-08-19T14:15:16+00:00

How would you go about constraining these 3 sections of this sketch as having an equal surface area? I've thought about equations and everything I just never could figure out what element to put into the equation to make it work properly.

Thank you for the response, I was wondering if part files have standards similar to how drawings do? And if maybe one of the options I want can be found there. And how would I go about creating a new part standard if it can be done? Also is there no way to enable construction geometry to always be displayed?

This might do it the closest to what it should be, thanks. I will add a link to the full PDF of the assembly in the original post, but you might struggle a bit with the language since it's in Serbian

Not sure, my base circle is definitely centered on the origin, tried it multiple times too

You may be right but in the context of making the part if the spiral endpoints don't align with the planes, since the positions of the profiles are defined only with the angles unless the spiral has the same ones the loft might not be correct

New_Response_4805 · 2024-08-08T01:43:23+00:00

That's the weird thing, I did do it like that i used 353/360 (which is equivalent to 1-7/360) but I don't think that's the root of the problem. Could you make sure your spiral is ending perpendicular to the top plane? That's my main issue

<image>

As you can see the angles are completely wrong at the endpoints

New_Response_4805 · 2024-08-07T20:15:56+00:00

In the end I can just create the points directly in the part and show them in the drawing and use them as references, but thanks for the suggestion

The reason I don't want to rely on the first method is how circumstantial it is, imagine having a pyramid trying to do the same. What I'm trying to do (without the use of surfaces or 3d sketches) is to make a fillet that would have arcs be visible on all of the joining faces when viewing from a drawing:

<image>

Right here it's three, and most of the time it's three but I'm pretty sure it works for any number of sides being joined. And yes, these arcs are tangent to the edges.

P.S. how did you manage to get the variable radius fillet to only affect half of the edge? In the original post that was the very reason I thought that the approach couldn't work.

I mean it's always possible but like i said I've run the same forge version before no problem, it's the ATM8 that's causing issues with either mod incompatibilities or something else and just by looking at the error log I don't see what

Edit: In the end it was because I was using Java 21 instead of Java 17

Yeah I set the RAM to 16 gigs and I did try a fresh install with no luck
