 # Class TransformBase

 Last update: 16.07.2025 

Namespace: [VM.Managed](VM.Managed.md)  
Assembly: VMAppCore.dll

This class is to represent the transform base. Getting the information of transform(TMatrix type) through TransformMatrix property. Getting the information of position(VectorBase type) through Position property. Getting the information of orientation(OMatrix type) through Orientation property. After picking, Getting information of TransformBase through picker.
