Hello,

I have a cylinder and I want to move his bottom center point to another point using Y scale.

Here is a sketch of what I want:

I try to do this, but without success:

```
float distance1 = P1.y - P2.y;
float distance2 = P1.y - P3.y;
float new scaleY = (distance1 * scale.y) / distance2;
```

I know the position of P1, P2, P3 and the scale of the cylinder.

How to find the new scale?

Thanks

good day.

do you want to fix top of cylinder ?

if you don’t .you only put distance1 and distance2 in the wrong order.

```
float d12 = P1.y - P2.y;
float d13 = P1.y - P3.y;
float scaleY = scale.y*d13/d12;
```

if not, check this

```
float l1 = d12 * 2;
float l0 = l1 / transform.localScale.y;
float l2 = d12 + d13;
float scaleY = transform.localScale.y * (l2 / l1);
float offsetY = -(scaleY - transform.localScale.y) * l0 / 2;
transform.localScale = new Vector3(1, scaleY);
transform.position += new Vector3(0, offsetY);
```
