# Why isn't the TPMS/Lattice thickness constant when I distort it?

## Issue:

I've distorted my TPMS and the thickness isn't constant after I've distorted it.

## Applies to:

* Varying cell size
* Warping
* Remapping

## Cause:

We are currently working on fixing this issue.

## Solution:

A **normalized** field is a first-order approximation of the implicit function.

**Method:** Normalize the Field of the TPMS by using the field property Normalized Field. This property is found in every field.

* Add a **Periodic Lattice** block
  * Unit cell: **Walled TPMS Unit Cell**
    * Unit Cell: Gyroid
    * Orientation: UVW
  * Cell map: **Rectangular Cell Map**
    * Volume: Cube (Size: 10)
    * Cell size: 10 x 10 x 10 mm
  * Approx. thickness: 0mm

* Use the **"normalized field"** chip or use the **Normalize Field** block.

* Thicken the Normalized Field to your intended thickness
  * Use the **Thicken Body** block
    * Body: Normalized Field
    * Thickness: 1mm
* Set Body Bounding Box to trim off the excess outside the design space.
* Bounding Box: Bounding Box from the Periodic Lattice block![Creating the normalized TPMS by applying a bounding box to the thickened normalized field.](https://files.learn.ntop.com/help-articles/lattices/6014391864723.png)
