# Curve Modifier doesn't work at all in some curves Not even deformation of shapes

I've been working on a project that is basically just a lot of bezier curves that I have to put some complex shapes on, I use the common Array with Follow Curve and then the Curve Modifier, it works wonderfully but there are some curves that for some reason seem to not work at all.

They don't even deform the shape on any axis, it just sits there doing nothing. Why is this? I checked all the settings in the curve tab but everything looks the same as the ones that work!

Blend File

Example of 2 curves

Edit: Updated file, as you start up you can see 2 curves, one that works with the modifiers and one that doesn't.

• Just from your file I'm having a hard time understanding what you are trying to do. Can you show images that exemplify which ones are working and which aren't?

• Okay; Look at these pictures: imgur.com/a/TwuuH 1st) I moved to 2 curves from the main layer to make it easier, one is already covered with the model, other isnt. 2nd) Here's the curve that works, with the model selected, as you can see it has the 2 modifiers linked to the curve inside, and it is following it as intented 3rd) Here's the model for the other curve, as you can see even with all the modifiers it stays the same, not being affected at all by the curve. Changing axis doesn't work. The properties of the 2 curves are the same. This is the problem. I'll update the file. Mar 20, 2016 at 16:23

I think curve called Problem Curve does really has problems. I couldn't reproduce this behaviour which is the fact that neither Fit Curve option of Array modifier doesn't work nor mesh can't be curved with it. Re-adding modifiers also won't change that.
1. With Problem Curve_Model selected in settings of Array modifier set Fit Length, set some random value, then return option to Fit Curve.
