[Plugin][$] Curviloft 2.0a - 31 Mar 24 (Loft & Skinning)

jeff hammond

Anyway, my question is:
Is there a way to make Curviloft create only quadratian faces?

Thanks,

post the .skp (or that portion of the model).. there's probably a way to get better results than the long triangles you're getting.. (via better curve segmentation and/or curvilot settings)

Hey community.

Im having a bit of trouble with this plugin. Maybe the way I am applying it or maybe Im doing something wrong. Could someone help?

Every time I attempt to loft an object along a path, the preview looks fine but the final result has tons of faces missing.

I am trying to get information on what the various options in the toolbar are once you see the preview, (ie, sampling, interpolating, etc) and what they do, but cant find any info on it.

Can some help?

Very likely you're working on something that is small and you're running up against the short edges/small faces issue. It would be most helpful if you would upload a sample SKP file that exhibits the problem you're having. Otherwise we're taking stabs in the dark.

Hey, great tool tat I've been using for some time.

Funny that only now did I come across this green dialog box stating:

"Handling Needle Eyes and other defects! -1"

Could someone enlighten me as to what this signifies?

Thanks!

There are a few checks on the contours, but this is not very accurate.

Needle eyes are defects which derive from the suprposition of two contours, creating small loops.

In general, Edge defects are better handled by EdgeInspector.

Great plugin, i am loving it! I have just discovered it silly me.

Still! Hope someone can help me out. I make 3d belzier curves, copy array 15 of them and place them behind each other with space in between. Group them after welding and then use Sketchy FFD to make an organic form of those 15 curves. When i then ungroup them, select them all and use Curviloft it starts working till around 90% and then Sketchup crashes. Can someone help me? Thanks in Advance. When i reduce the curves and just use two of them all is good. Working on Mac with 16 GB RAM.

Kashaki!

Is there a way to control the face normals? In this example, I was not able to get the right face orientation...

The best would be that you post your model. There may be many reasons why Curviloft have big troubles when the geometry could includes defects.

Curviloft is not really managing face orientations. This is one thing I have to change when I update it (I understand now better the logic of Sketchup).
But you have several plugins to reverse or align face orientations now.

Yes, I'm able to change those I just wanted to make sure I have not overlooked any option to change it directly.

Hi - I have been using this great plugin to design a sailplane wing. I hope to be able to create either a mold or plug using a CNC router from the design. The main part of the wing and the very small end portion of the wingtip are done, but the elliptic section in between won't loft.

In the attached file, there are 7 curves representing the airfoil shape at different stations along the wingtip. Everything has been scaled up 100x to avoid the "small edge" problem. The trailing edge of the foil is left open as it is easy to add this face once the rest of the surface is lofted.

I can loft between most pairs of adjacent foils successfully, but when more are added, Curviloft "twists" the vectors at the trailing edge. The problem seems worst on foils 3 and 4, counting from the root. I have tried untwisting them using the plugin features, but I can't get that to work.

The edge count in the foils is pretty high, as these are automatically generated by an airfoil program. I don't have any convenient way to control this. I have a feeling that if this could be reduced, it might work. I was hoping though that some one would have another suggestion.

Thanks!

You can use another of Fred's excellent plugins to cleanup before lofting.
Here it is cleaned with Curvizard then Curviloft.

That is amazing, thank you so much! I installed Curvizard, followed the video, and everything was looking good until the last loft segment. Then I got a bugsplat.

Any ideas? I'm using Sketchup 2013 on a Mac if that makes any difference.

Hi Box -

I have been looking at the documentation for Curvizard and I see there are quite a few settings on the buttons palette that affect the way the tool works. Would it be possible for you to share with me the settings you used to clean up the curves? The video above is tightly cropped so the settings are not visible. Thanks!

You may have been able to loft it, but can you make it into a solid? I have been able to loft using 4 the airfoils, but even though it looks good, there are too many errors to make it into a solid. I can get faces on the root, tip, and trailing edge, but Solid Inspector**2 finds hundreds of problems that it says cannot be fixed automatically.

This is with Sketchup 2015, I upgraded to see if that would improve things. It didn't.
