### 4/5 — Good but…

*2024-06-14, version 2.1.1*

Tetra is a good 3-D modeling software, but I wish that there was a way to import images onto the polygons or import 3-D models.

### 3/5 — It needs work.

*2023-11-28, version 2.1.1*

It’s a fairly enjoyable pastime, until it starts getting real touchy and you lose everything you were working on. Good luck getting it back. It’s too touchy. Then it becomes an annoyance.

### 1/5 — モデリングできないけど、、

*2023-10-15, version 2.1.1*

小さい球体を操作してモデリングするようだけど全く動かせません。
ただデフォルトの立方体を眺めるだけ、、どうやるの？
