Undertanding Mapping
This page describes the different types of mappings available and the mapping process.
Description
The mapping determines the distribution of the patterns on the support.

Types of Mapping
Different types of mapping are available when creating a 3D Texture. Each type describes a way to
create a virtual grid that is going to be projected on a part’s surface:
- Automatic mappings: these mappings are automatically calculated and you only have to set few parameters to obtain the desired distribution
- Mapping files: mapping files are *.txt files containing all the information needed to generate the mapping. It allows you to generate a completely customized mapping and/or save a mapping you designed with the automatic mappings and use it in another CAD system where Ansys software is integrated.
Mapping Process Example
The following example explain mapping is applied. The example uses various options to show capabilities.
- Mapping: a virtual grid is created using standard parameters (distance between patterns, mapping length, etc.).
- Filtering: a quilt or a face is used to define the grid limitations.
- All the patterns included in the limited grid are projected along the Z direction on the first encountered surface of the selected part.
- Shift: an offset (shift along Z) can be applied on the projected patterns.

Limiting Surface
The Limiting Surface

allows you to apply a surface on the geometry on which you apply the 3D texture to limit the 3D
texture to that specific surface.
Important: The Limiting Surface must be composed of
only one face. If the Limiting Surface is multi-faces, the
3D Texture will be applied on only one face.

Offset Surface
The Offset SurfaceMapping Offset

is a shift surface that allows you to apply an offset to the projected patterns along the Z direction
according to the origin of the 3D texture's axis system.
The Shift scale helps you define the offset.
