Hi, I just installed LibFredo and the latest Curviloft plugin. It works fine when I have 3 or fewer profiles, but I'm trying to connect at least 5. How can I accomplish this? All the profiles are simply copies of the same thing, but it won't work when I try to connect more than 3. I am using an imac on High Sierra 10.13.3, Sketchup Pro 2018, and Curviloft 1.6a. The profiles were first drawn in AutoCAD as polylines and the dwg was imported into Sketchup. They are closed line shapes with no surface in between. I have a screen recording, but it's too large to upload. Is there another way I can send? All advice, tips, observations are welcome!!

I think it's best to post the model (or an extract of the model with the 5 profiles).

Fredo, if you plan to make another update to Curviloft, could you please increase max. values of these parameters: Simplify from 0.15 to 0.8 or something (0.15 is very little, in some cases I'd need much more), Sampling and Interpolation from 40 to 100? With previous releases I would have done it by myself by simply editing CurviloftPalette.rb in Notepad but now these codes are encrypted.
will go in next version

And secondly, there's this bug that when I use the tool, close it and open again, it doesn't bring that menu bar on viewport's top to adjust options but goes straight to generating junction. And I can't come back and set connection options. Have to open a new model and copy my geometry to it. I think it was already discussed somewhere so I'm just bringing it "in the board".
Not sure I understand. Curviloft never goes directly to generate Sketchup geometry. It ony goes to Preview mode when you have an initial selection.
Could you clarify and illustrate your case.Thanks

Sorry, fairly new to this, but thanks for the quick reply. All I have are screenshots, couldn't get the screen recording small enough to upload. The 5 profiles change color after I hit the green checkmark, but never actually form a plane..See attached images! I just started a new post under the same name with my sketchup model attached. Also attaching here..Let me know if that helps!

@LO_Inhabit
Very simple. Your model is at a very small scale, with a lot of tiny edges in the profiles (<0.1mm). Sketchup does not like this, and Curviloft neither.
Just scale the whole model by x50, and Curviloft will make the tube without problem.

Aha! I knew it had to be simple!! Thank you so much, Fredo!

NEW RELEASE: Curviloft v1.7a - 23 Feb 18
Curviloft 1.7a is a maintenance release with the following additions:
- Parameters can be preserved across Sketchup Sessions. For compatibility reasons, the option must be enabled in the Default Parameters dialog box.
- Toolbar icons in SVG (Thanks to RichOBrien) for SU >= 2016
- Bug fixing
IMPORTANT: It requires LibFredo6 v8.1 or above.
See Plugin Page of Curviloft for Download (or use the Sketchup PluginStore plugin for auto-installation.

Thank you Fredo, was hoping exactly for this!

Thanks for the update and for informing us so quickly.

You're welcome.
One day, I'll need to update the GUI to make it clearer (and cleaner). After all these years, I realize that Curviloft is still in Beta!

Referring to "preview mode bug":
when I select contours and run Skin Contours (or preselect the tool, regardless) I cannot bring the grey toolbar to set parameters. It goes straight to surface generation.
I tried various sets of contours, every time the same thing happens.

Your profile says you use SU2014. Is it the version you use for this buggy situation?Fredo

I'm using SU 2017 (updated my profile just now) and updated Curviloft to newest version.
I was thinking, if you have time, you could create another command in drop-down menu like "Go back to settings" next to "Go back to contour selection". -

Does it happen with any model?For going back to Preview from Generation, just use the Orange Back Arrow in the palette.

As in the screenshot, I cannot see Orange Back Arrow, no arrows at all. The tools gets stuck at the stage of generating geometry. It happens when I create a set of contours which is too difficult for the tool to process (precisely: to distinguish where one contour ends and starts next one - this is how I understand it). I still can select contours manually but I cannot adjust properties because the grey toolbar never appears.
Here's an example model - when I select contours and run Skin Contours, no surface is generated. Then I go back to contour selection, pick them manually and OK, the surface is being created but I cannot add sampling, interpolation etc.
What's more, if this happens, entire model gets "infected" and the grey toolbar doesn't appear anymore, even with other contour sets. Until I restart SU.

I have not seen a screenshort in your post. The Orange Back Arrow is in the button palette.
For your model, Curviloft is not perfect, and there are situations where it looses control. In your case, and more generally for skinning, it is a good practice to put small delimitor edges to help Curviloft find out where to cut the contours.

One trick I have found when trying to CL a perimeter that is conjoined with other entities in the model is take a copy of the perimeter and move it (on an axis) out away from the model.
That makes it far easier to edit out anomalies that prevent the mesh from forming. You can also simplify the perimeter by deleting 2 adjacent short lines or deleting fragments and make one endpoint to endpoint line in their place.
Then you can create the surface without problem.
After which move the meshed group back to the model along the axis and cleanup the model where the lines should meet the surfaces endpoints.
-
In other words: my problem is not that I cannot create a surface - I can manage it. I cannot modify parameters of generation: sampling, interpolation etc. Here I put the screen again, it shows yellow processing bar. At this stage I cannot call back that grey settings toolbar. Even if the mesh is created. I said about "difficult" contour sets because they stop the toolbar from showing, even though the surface is still being generated.

NEW RELEASE: Curviloft v1.7c - 27 Feb 18
Curviloft 1.7c is a major maintenance release fixing bugs in the Edge Selection process
In particular, Curviloft displays a message box whenever the contours are not complinat with a generation of geometry. This is the case for the Skinning tool when selected edges cannot be interpreted as sequences of 3 or 4 curve portions.
IMPORTANT: It requires LibFredo6 v8.1c or above.
See Plugin Page of Curviloft for Download (or use the Sketchup PluginStore plugin for auto-installation.

FYI, the last couple of weeks I have had numerous crashes. I,m not sure, but it could be when dealing with large- segmented curves or with very small curves whose segments or angles are beyond SU tolerances. I believe 2017 and 2018 will now warn if arc-segments are incompatible when trimming, for example, the corners of a rectangle. If. Curviloft doesnāt error check for this or other warnings could this could problems? There were cases last week when merely passing the Progflileās cursor over an edge, without pressing the mouse, would crash SU.

Hi!
I want to post a quick movie and my model to illustrate a bug that I described some time ago but maybe didn't explain clearly.
I had problems with curvilofting some more complicated contour sets, using Skin Contours. I was advised to draw manually "separation lines" at contour borders and that helped. But sometimes I forget or don't know that a certain set needs such separation, then I perform Skin Contours onto a problematic contour set and then Curviloft gets stucked. It endlessly shows yellow progress bar on top of viewport and doesn't let me back to settings (grey toolbar). Since this moment I cannot recover this toolbar with loft settings, until I restart SketchUp (which is very asspainful having almost 200 plugins installed).
The model shows a few complicated sets of 4 curved contours. The video shows the issue which comes even with simple contours after a difficult skinning is performed. It happens even if I start a new model in SketchUp.
Please tell me somebody if you also have this problem or is it just my computer...
