# DMPlexTransformExtrudeGetTensor
Get the flag to use tensor cells 
## Synopsis
```
#include "petscdmplextransform.h" 
PetscErrorCode DMPlexTransformExtrudeGetTensor(DMPlexTransform tr, PetscBool *useTensor)
```
Not Collective


## Input Parameter

- ***tr  -*** The `DMPlexTransform`



## Output Parameter

- ***useTensor -*** The flag to use tensor cells



## Note
This flag determines the orientation behavior of the created points.

For example, if tensor is `PETSC_TRUE`, then
```none
  DM_POLYTOPE_POINT_PRISM_TENSOR is made instead of DM_POLYTOPE_SEGMENT,
  DM_POLYTOPE_SEG_PRISM_TENSOR instead of DM_POLYTOPE_QUADRILATERAL,
  DM_POLYTOPE_TRI_PRISM_TENSOR instead of DM_POLYTOPE_TRI_PRISM, and
  DM_POLYTOPE_QUAD_PRISM_TENSOR instead of DM_POLYTOPE_HEXAHEDRON.
```
