A feature suggestion (with patch):
Set curve frames to curve length. I regularily use curves for animating car and train movements, and for me it is confusing to think “frames” instead of meters.
Therefore I added an operator that sets the frames to the length of the curve.

Good morning!

I’m tring to this addon, but when I try to make a loft with 3 or more curves, it does nothing. Loft and auto loft only work with 2 curve.
step by step:

add 1 curve,
copy and moving a bit 2 times
select auto loft
result nothing :spin:

what i’m doing wrong?

I’m working on linux with last version both of blender and the addon.

n1k0l4 · January 4, 2017, 9:38am

nobody can help me?

mkbreuer · January 4, 2017, 11:41am

More than 2 for this loft tool is not possible. unfortunately!
See collapse menu title.

AutoLoft only ‘hook’ the generated mesh to the curves after excuting the loft operator.

select 2 curves
execute loft for mesh generation
enable autoloft and move or edit one or both curves
than
add or select a new curve and repeat the previous steps (1+2)

thanks for reply

Is that maybe a regression?

because on the first version making a loft between more than 2 curves were possible…

mkbreuer · January 5, 2017, 4:03am

I agree with you!
The 1.5 version is the best one for direct 3d view editing.
I hope it comes back…

Meta-Androcto · January 5, 2017, 4:26am

not likely as no-one maintains & api changed too much. imo the auto loft functions are far better working & it was only my persevere & begging devs familiar with the code that restored the functionality this far. most likely we will write a new addon for curves in 2.8

mkbreuer · January 5, 2017, 8:04am

I would like to help, to make a new one, but this stuff is to complicated for me.
Your Auto Loft is a greate alternative of course.
Maybe someone want to start a crowdfunding project for it?..

kattkieru · September 18, 2017, 12:07pm

Sorry for the thread necromancy, but what is the license the curve code is released under? If there never was one, could the author(s) please officially give it a license?

Mackraken · September 18, 2017, 3:49pm

Hi kattieru. The original script curve_tools.py is under GPL and the continuation from guy lateur does not look to have one. Feel free the send him a message. May i ask why are you interested?. Thanks.

Meta-Androcto · September 18, 2017, 4:19pm

odd, seems the no gpl block needs to be fixed.
please note we have curve tools2 in nightly blender builds and the files are here:
https://developer.blender.org/diffusion/BAC/browse/master/curve_tools/

@mkbreuer
hi, the original curve loft was totally broken, so I had asked batfinger if he would look at writing a loft to replace it.
The replacement was not exactly the same, but the auto loft feature is quite nice still and worth having.

thanks.

guy_lateur · September 19, 2017, 12:44am

I’ve never really bothered with licenses. You can use my code as you see fit. I do request that if you just plainly reuse some of my code, you give me a mention as the original author. That’s just a question of common decency, though; I won’t take any legal action if you don’t do that.

@Meta: if you want to put some kind of license on my/our code (just to make things clear), you’re free to do so.

kattkieru · September 19, 2017, 6:15am

@Mackracken: Licenses are important when you’re working at companies and may have interest in using code as a basis for something larger, even if you’re only looking at the code for reference.

I’m only interested in Curve.py, as I hadn’t seen anyone calculate things quite like this before (the split into “segments” is a nice touch) and I was considering taking the technique.

guy_lateur · September 19, 2017, 6:21am

Sure, help yourself. Like I said, a mention in the credits would be nice…

alengo · October 17, 2017, 1:51am

Hello. I can not run this script under blender 2.79. How can I do this?

guy_lateur · October 18, 2017, 1:59am

You can’t. The addon is broken and no longer supported. Sorry.

atekdigital · October 19, 2017, 7:54pm

How to install the addon. I have download the zip file and install the zip file but i cant get in the search box to activate. I tried only with the curve addon copied on desktop and install yet cant find the addon to activate. Im using 2.79. Do i have to install the zip or the single and why its not showing in search to activate.
