# Bounds Question

## Recommended Posts

Hi All,

Am trying to understand hyperstudy using Shapes and I have encountered a bit of a headscratcher.

My plate has a hole with a radius of 50mm and I want to examine the effects of changing that radius. When I apply a shape to it and get to hyperstudy it asks me for an upper and lower bound (default -1 and 1) and an initial of 0. My question is, what exactly do these numbers relate to? When I run it creates a hole 37.5mm and 62.5mm radius respectively, but how does that relate to lower and upper bounds of -1 and 1? OKay it has consistently created a difference of 12.5mm but how did it calculate this?

Many thanks in advance. Is there any way I could have just said initial = 50mm, lower = 45mm and upper = 55mm?

Regards

Andy

Anyone at all????

Value of 0 means donot apply the morphing shape
Value of 1 means apply the full morphing shape
Value of 0.5 means apply half of morphing shape
Value of -1 means apply in reverse(so if you lengthen something then -1 means it will actually shortens it)

That's what these numbers mean in the context of shape variables.

Many thanks Rahul,

i did some more experimenting, would be correct in saying that the amount 1 relates to (in my case 12.5mm) is based on the morphing process I used to create the shape?

Kindest regards

Bounds you can change directly from input variable step.Please refer attached screenshot.
