Problems With Mesh and Curves

[JuanGamerPlayz (Juan)]

Hello there! My name is Juan, and I am new to this little forum with many artists from the Blender Community!

I created this topic because I am experiencing some small problems with a mesh that I have created and curves (specifically, BezierCurve). While designing a wooden fence and using Array and Curve through the Modifier properties, I noticed two issues:

(NOTE: While being a new user, I can only create topics with one image. Therefore, the picture for the second issue is going to be featured in my topic’s reply.)

1. Some parts of the fence are not linear as expected:

2. Both sides (Left and Right) are not equally correct.

Based on the results, I tried adjusting the position of the fence to see if it would make a difference, but it only made it worse, leading me to press CTRL+Z. I also experimented with the Spline type, testing all three options, but it didn’t seem to be the cause. As a result, the problem persists…

Is there anyone who can help me solve this? I would greatly appreciate any assistance in making my creation perfect!

Thank you!

With the quote said above, here is the second image of the issue:

2. Both sides (Left and Right) are not equally correct.

Furthermore, if it requires me to show more pictures regarding the Modifier properties I put on the fence mesh, let me know!

Yes, this is a known problem with extruded curves when they change directions…there are 10s’ if not a hundred help wanted with this…
Look into Z-curve-sweeper does a far better job on transitions like this and Geometry Nodes.

z-Curve-Sweeper for Blender 3.0+ (Curve-to-Mesh with superpowers)

Update: Face-Corner UV generation added for seamless UVs, thanks @quellenform for help. [Z-Curve-Sweeper] Available here for free: Does all the stuff from my previous node-groups (even-thickness, UV mapping, Z-Up project, etc.), and more (like curve-sweeps from points, profile curves output and mesh profile). Feedback welcome.

Hi and welcome

Thanks for the shoutout @RSEhlers but the z-Curve-Sweeper won’t help in this case.

There are GN solutions for your issue, like here:

Instancing an object through a curve with fixed distance between each instance

Here is both methods (The trim method slightly refined to remove “jumps”): [image] …The Trim method works in 3.4, whereas the Sample Curve method for multi-curve setups only works in 3.5 alpha. They give exactly the same result. Good luck.

or this:

An Array on Curve of two different objects (with different dimensions) made with Geometry Nodes?

2 objects along curve.blend (118.7 KB) The resample: [image] The instancing: [image] Makes: [image] …only works with 2 items and with single curves… things in the instancing collection are aligned on the Y axis here… Would need a way more complicated setup to work with more than 2 items and multi-curves. Good luck!

but if you don’t want to use GN then there is a pure modifier technique also like in this tutorial by Artisans of Vaul:

Array along a curve without the object deforming in Blender

Good luck!

Oh well…
Thanks for stepping in to help the OP…
