PUSH

## Name

push — Forces the effects of all transformation matrices that appear in any combinations in the trees from the specified objects down to the primitive shapes.

## Synopsis

`push` [`objects`]

## DESCRIPTION

Forces the effects of all transformation matrices that appear in any combinations in the trees from the specified objects down to the primitive shapes. This will change the parameters of the primitive shapes if any of the transformation matrices are not identity matrices. All the transformation matrices visited will be set to identity matrices. This command will fail, and no changes will be made, if any primitive shape referenced by the list of objects is positioned differently in two or more combinations. The xpush command will perform a similar function, even if some shapes are multiply referenced.

## EXAMPLES

The example shows the use of the push command to push the effects of any transformation matrices in the trees headed by two specified objects down to the primitive shapes.

Example 1. Push the effects of any transformation matrices in trees headed by two specified objects down to the primitive shapes.

`mged>``push group1 regiona`

Pushes the effects of any transformation matrices in the trees headed by group1 and regiona down to the primitive shapes.
