The Math Mesh addon allows us to define a mathematical curve between two vertices. Think of a sinus soundwave where you can set the frequency and skew. This comes in handy when we want to make curtains or corrugated sheets.

#### How to use the Math Mesh addon?

It might be a bit tricky at first, but it is pretty simple. Here an example.

- Enable Add Mesh: Extra Objects, if you don’t have it enabled yet. (It’s very handy).
- Press
**Shift+A, and then: M,S,A** (That is Add Mesh, Single Vert, Add Single Vert) **Press 1** for Vertex Select Mode. Select the vertex if it is not selected yet.- Press
**Shift D, X.** and move the second vertex a bit away from the first one. - Press
**A** to select All. - Press
**F3** and type: **Math**. Click Math Mesh. - An operator will pop up where you can adjust settings for the curve.

#### Settings in the operator

- Curve Type. You can choose between Circular and Sine. Circular curves are a bit more round and Sine sharper.
- Curve Plane. On what axis in the viewport you want to have the curve on. (XZ, XZ, YZ or View).
- Number of Curves. Defines how many curves you want between the two vertices.
- Curve Vertices. Defines how many vertices you want that define each curve.
- Amplitude Type. How the amplitude is calculated.
- Amplitude and Power. Not sure what the difference is, but they both seem to influence the amplitude of the curve.
- Skew. Skews the Curve.
- Alternate. When you switch it on, you will get absolute values, meaning -1 is 1. (You want negative part of the curve, or not).

#### Where can I download the Math Mesh Addon?

You can download the Math Mesh addon on Github. Installation of the add-on in Blender 2.8 goes as usual. On Github click the green button to download the .zip file. In Blender you go to Edit > Preferences > Addons > Install. Then Browse to the .zip file you just downloaded. Press Install, activate the addon, save preferences and refresh.
