I've had loads of issues around getting objects to fit and follow the multiple curves in my project. I've searched and overcame every obstacle but one, that I'm aware of lol. I continue to have an issue with the array modifier, using fit curve, not fitting the entire length of certain curves. I have had this modifier work the first time on multiple occasions on brand new curves. However, the curves I'm specifically having this issue with were originally edges of a mesh selected with vertices, duplicated, separated, and converted to curves. Some of these problem curves were joined together as they visually create a continuous line.

As far as I can tell all scale values are 1 and apply scale has been used multiple times between all my problem curves and hasn't resolved the issue.

When using the fixed count fit type, I can push the array past this stopping point, but the array fails to follow the curve past that point. Specifically, the arrayed object just continues straight in one direction.

I literally opened Blender for the first time 5 days ago so this issue has to be a user error. I just haven't nailed down what I'm messing up and the old google machine hasn't produced a working solution. Happy to post my file, I just can figure out how...

If you make a default cube, and a default circle, the default cube is 2 units wide and the default circle has a circumference of 2pi (2 * radius * pi). How do you evenly array something 2 units wide into something 6.28... units longs? You can't. 2 doesn't go into 2pi evenly. So Blender makes 4 of the cubes. (Differences in yours may be due to unapplied scale, but it doesn't matter; you're not going to get any array to fit any curve exactly.)

As for things failing to follow the curve after its end-- there is no curve after the end. If you want it to continue to curve, create more curve. Which you can do by entering edit on your curve, selecting a control, and 'e' to extrude it.

Now, you might find it useful to enable "stretch" and "bounds clamp" on your curves, in properties/object data/shape. If you do this, any curve modifiers you use will stretch the modified mesh to fit the curve-- so those 4 cubes, 8 units long, 2 units each, will turn into 4 cubes, 6.28... units long, pi/2 units long each.

  • $\begingroup$ The curves are large and an exact fit is not necessary. $\endgroup$ – Brewsker Jan 23 at 7:29

I decided to redraw the curves. It was easier and just simpler to use the problem curves as snapping points for a fresh bezier to be placed. For what it's worth, I appreciate the info.
