Re: How to add a curved array from the curved shapes workbench to a body in part design

Well, I actually got what I wanted using a multi-section sweep. It was a little tedious to get the outer profile exactly right to make the sweep work they way I wanted, and I had to include two edges of my boundary box, but it does work, and I can polar pattern it with no problem. Well, I guess I ju...

Re: How to add a curved array from the curved shapes workbench to a body in part design

I just did a quick trial doing a sweep rather than a Curved array, and it all passes geo check. (Note: I did not spend much time trying to get the dimensions or shape of the blades.) Maybe there is some wizard level knowledge needed to get Curved array to make valid geometry. :?: Yeah, a sweep will...

Re: How to add a curved array from the curved shapes workbench to a body in part design

Okay, so the real question is, why does it fail the geometry check? Earlier, someone mentioned that the error was related to using offsets, or something to that effect, but I'm not using offsets in the Curved Array. I tried making changes to it, but to no avail. Have you heard back from @christi? Y...

Re: How to add a curved array from the curved shapes workbench to a body in part design

Yes, it is what I want. I have applied a twist to it, and my boundary curve also scales the shape as it goes outward. The shape is exactly what I want, it's just that I cannot use it in my overall part design. Just trying to add it to main model is where I am having the problem. The suggestion of us...

Re: How to add a curved array from the curved shapes workbench to a body in part design

I am not sure the Geometry-Check warnings are the culprit. They are Geom_Abs_C0 warnings on the trailing and leading faces of the blade. This happens because they are generated from half-circles that are converted to C0 Nurbs curves. But I think these Geom_Abs_C0 warnings are only important when us...

Re: How to add a curved array from the curved shapes workbench to a body in part design

I don't have any errors in the curved shapes workbench.

I just cannot use the curved array created in it, in the Part Design workbench, combining it with my other elements of the model.

Re: How to add a curved array from the curved shapes workbench to a body in part design

My profile is all connected using tangent constraints, so there shouldn't be anything that is not smooth.

Re: How to add a curved array from the curved shapes workbench to a body in part design

Why don't you use a Draft PolarArray ? Edit: A Fusion doesn't work because the array shows geometry errors. Is a compound enough for you? I don't know why there would be geometry errors in the array, but that's probably because of the way the Curved Shaped workbench does the curved array to begin w...
