# How can I add thickness to this animating curve?

I have imported a LaTeX figure from a latex2Blender add-on that I downloaded. I then converted the figure from a mesh to a curve. I then added a build modifier to the curve. The curve animates itself nicely.

However, I want there to be some thickness to the curve. I would prefer for there to be 2D thickness instead of 3D thickness if possible. In other words, I don't want to trace out the curve with 3D tubing. I tried everything in this post: How to add thickness to a curve? , but nothing worked for me

Here is the file:

• yeah that looks perfect for the end result of the animation Oct 20, 2021 at 0:31

You can use an object to bevel the curve. In this case a very very very tiny path.

Add a Curve > Path (Shift+A). This will create 4 m tall NurbPath object.

In Edit mode, scale it down to 0.000001 (S0.000001Enter) and 3x up again to make it thicker (S3Enter)

When it has the right size you can use it as a bevel object for the Latex Figure.001 curve:

End result of the animation:

• Thanks. I tried doing this on the "a" and ended up with poor corners imgur.com/a/sPWyGex . I also tried it on a "b" and ended up with some weird lookin end-tips : imgur.com/a/E5wa7zc Oct 20, 2021 at 1:17
• Hm. Which Blender version do you use? I've used 2.93.5 in the answer but just tried 2.83.9. There it results in an even worse shape. Oct 20, 2021 at 2:21
• So I upgraded from 2.93.1 to 2.93.5 and I'm still getting the messy tips. I noticed that in the first image you uploaded, your nurb path x y and z scales are all set to one while the x dimension is .000012. Whenever my x dimension is .000012, my x scale will always go to 0, even when I try using the lock button. It says it's 0 but when you click on it to expand, it's actually 0.000003 imgur.com/a/fixJKPf Oct 20, 2021 at 3:21
• I bet that you scaled the nurb path in Object mode. You can do this in Object mode but you need to apply the Scale with Ctrl+A afterwards to reset the scale to 1.000. I've scaled it in Edit mode. Then you don't need to apply the scale transformation and it will stay at 1.000. Oct 20, 2021 at 3:35
• Ok I got my Transform tab looking like yours and I'm still seeing the messy tips and corners. Would it be best for me to see your file at this point and see how it looks on my computer? Oct 20, 2021 at 3:48
