Follow and Keep?

Profile Builder also may work for your needs.

Jason.PB performs a follow me operation and will twist.

FAK keep will not twist but does not keep elevation in 100% of cases. 1001 bit tools will work. It has a free eval period that you my want to check it out...
Clarification: FAK elevation comes into play when you go over a "hill" and for railing this should not be an issue

Thank you & I need learn some more~!
-
good tool man, thanks for sharing!!
-
I've tried it as well. Thanks Fredo for such a wonderful tool. Can you get it to maintain a sharp edge? I noticed it round the corners. Would be nice to have this as an option if available.
-
only amazing ....

Fredo, this tool is brilliant. Thank you so much. I am using it for 3D Printing, and the one issue I am struggling with are "holes" in the shells, that make the resulting STL files cause trouble in the further printing process. Do you have any advice on how to avoid such tiny holes, or what situations to avoid that are prone to causing them? Thanks, TrisQ

When you make complex geometry in code [and sometimes by hand] tiny tolerance issues result in microscopic holes. If your initial geometry is too small this can be more prone. Sketchup/OpenGL can't create faces <~1mm [0.01sq"] but they can exist later - so making something perhaps x10 the final size and scaling it down later by x0.1 will avoid many problems.
There is an excellent tool by Thomthom - 'Solid Inspector' - which highlights 'errors' in your near-solid groups and lets you see where they are, so you can fix them. Look in the Plugins Index [big red button above here] - http://forums.sketchucation.com/viewtopic.php?p=250026#p250026 > http://forums.sketchucation.com/viewtopic.php?p=267832#p267832 -
I found in some complex skinning that CL may either not skin, or will partially skin, or twist the skin, or seem to work (black pre-skin looks OK then an empty group results), or in rare cases, leave tiny gaps as you have experienced. But when I do these complex skins in sections, then later explode the multiple results, CL does work quite well, most of the time.
Also reducing the complexity of the guide curves helps a lot.
Perhaps you could do your CL skins in sections to see if that helps.
-
While I am looking at this topic, I'd like to add a suggestion for Fredo to ponder.
Fredo; is there any way you could be a bit more specific when CL finds an error in the selected guide curves? Right now, if CL cannot form a skin, it colors the guide curves, but there is no indication of what caused the error, which 95% of the time is a tiny gap somewhere. Otherwise it usually is a tiny extra fragment/double line in the selection.
Fragments are relatively easy, but time consuming, to find, so a clue as to where it is would help a lot.
Tiny gaps almost always require a near total redraw of all the line segments, so any indication where the gap actually is would be tremendously useful.

have you tried this http://www.smustard.com/script/StrayLines -

have you tried this http://www.smustard.com/script/StrayLinesI think I looked at this some time ago, and found it not quite suitable in several, but common to me, occurrences. It works well with lines, but I had too many "no finds" when 2 or more vertexes of existing faces had a "no-face" micro gap between them. Maybe I used it wrong, dunno; too long ago.
I will try it again; thanks.

Applying multiple times helps some times and of course it does one seg at a time ,so you can make a stray line shorter and shorter
There are programs with filters that allow you to close close vertices based on a tolerance you input. Meshlab comes to mind but would not recommend you use. Check out ThmoThoms clean up since it may have a similar function. You may need to contact him to find out how to modiy code if it uses a fixed tol -
Soft Diagonals Feature?
Hi Fredo
Any plans to allow Curviloft to generate meshes with soft diagonals? This will enable Curviloft meshes to be edited with thomthom's new quad face tools (if i'm not mistaken)
Cheers,
Joel

Posted in another of my threads, this is slightly edited version.
Curviloft; when it fails to form a surface (as part of a solid construction), even though it shows a black pre-form surface, still generates an empty, or perhaps an almost empty group that SU interprets to be as a non solid. Solid Inspector will correctly say it finds no errors, but SU will not see it as a solid. And if you try to re-do that failed surface, you get another empty group.
The only way out, is if you know you do have a valid solid after a Curviloft fail, but SU says not, then edit the solid and do a sweeping left select to select everything. Using TT's selection tools, select only groups, and there it is. Just hit the <delete> key to get rid of it. You cannot select just that empty group. If you have other valid groups in that selection, then deselect them first.
Fredo.... Could you please do something about NOT creating an empty group when CL fails to form a surface?

Thanks for signaling this problem. I will indeed fix it.
Do you have an example of a model where it fails?@ivreich said:

I have plans!
Note that it will slightly slow down the generation of the faces however.Fredo
