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

[Mvmcneil]

I am testing a lofting workflow on simple geometry and Sketchup keeps crashing when trying to loft simple lines.

The process is this:
Draw a line
copy 4 times some distance
move 3 lines vertically up some to distance
select each line in sequence left to right
run curviloft

The tool activates then hangs sketchup. If I loft arcs or other shapes it seems to work fine.

I am using Sketchup 8 and Sketchup2013 on OSX 10.8.5. Both seem to be affected.

Thanks,

Mike

I just install curviloft plug in and I cant see in my sketchup window. Any comments please? im a newbie here. Thank you admin ...

Some more infos woudl help us to help you (how did you install it, ...)

Try it the other way round: run curviloft and afterwards, select the lines in the right order.

As cotty says, more information would be useful. I expect you've not installed it correctly and/or you didn't bother to install the required LibFredo6 files.

How about posting an example SKP file of what you tried to describe?

The file is not complicated is it only 5 lines and nothing more and it is a fresh file just after Sketchup starts. This is created in Sketchup 8.

I did try as Cotty suggested above to run Curviloft then select the lines. It worked and didn't crash Sketchup, but other geometry seems to work without running Curviloft first.

It may not be complicated but you don't describe which direction you copied the lines or how far. why would you even want to use Curviloft of those lines? What sort of result are you expecting?

I am using a workflow process that is not uncommonly used in Rhino to connect two planes or surfaces without using arcs. I am trying to use simple geometry as a test first before it would be used later on a more complex model. I like to test things like this out on simple models before I try incorporate it into my modeling process, and I noticed this was causing sketchup to freeze on OSX. I am not sure if the same behavior happens in Windows as I am not at work to try it in that environment.

I do not understand what you think CL will do with a set of unconnected lines. CL needs a closed perimeter of some sort to create the intervening mesh. With 5 parallel unconnected lines, CL can do nothing. I tried it and got the usual CL "I'm stumped" color codes. It did NOT hang my system.

Selected the correct way it creates this, but the wrong way freezes SU.

It works fine for me, too.

It doesn't need to be a closed loop.

hello,

I autoinstalled Libfredo 5.2 and curviloft using skecthucation pluginstore 2.0. But now I am having trouble locating them in sketchup in order to begin using them. Can anyone help. Thank you.

[Dave R]

Did you read the first post in this thread? It tells you where to look.

[jasonotero247]

I did look under the tools tab and there is nothing there.
I am using Bootcamp, Windows 7, SU 2013 and using the sketchucation plugin store to autoinstall the plugins.

Hi everybody,

I have the same problem as Missy_X a few posts above.
Whenever I activate one of the Curviloft functions in SU2013 (Windows 7, 64Bit), the "Curviloft: Temporary" window pops up immediately. I don't get the usual Fredo-Bar on top of the editor and the plug-in does not work. I can select edges behind the popup, but there's no preview and no lofting.

The Ruby console shows nothing at all. I do have all the latest versions (including libFredo 6.5.2) installed.

This is going on for a few days now. The plugins used to work fine. My current workflow relies on setting up 3D-Bezier curves and skinning them with Curviloft.

Any help would be greatly appreciated.

@daloop,

Could you post an exmaple of the error traces (there is the button in the temporary window to export the trace file).

Thanks very much

Thanks for your support.

Sorry, but I can't find any buttons on the window:

Then, could you post the model you are working on.

Thanks

OK, here we go:

Curviloft does not know how to skin continuous loops. You should use TGI3d for that (or maybe Soap Skin & Bubble).

With Curviloft Skinning, you need to cut the contour into 4 pieces. This can be achieved by creating small breaker segments as shown in the picture.

Then, you can skin the shape.

Thanks again.
To see if I got it right: If the tool stops working and I only get the temporary window, I have to break up the curve.
May I humbly suggest a future version of Curviloft that behaves a bit more gracefully?

Attached is a lofted version I did last week. It is much more along the lines I need, as it is less concave than yours. It could be, though, that I broke the curve by lofting another, adjacent surface. But not into more than 2 pieces.
Loft13.zip
Any idea how to control the concavity? I can't change the Bezier curves, as they have real-world constraints.
I did try Soap Skin & Bubble but I like the Curviloft surface better.
