Notes on Importing and Placing 3D Data
* 
Imported 3D data that has been converted into a 2D Arbortext IsoDraw file using the keep 3D data projection type can be returned to 3D mode via the 3D Transformation command.
Placed 3D files can also be returned to 3D mode and edited further there using the 3D Transformation menu command. The different ways that placed 3D CAD data can be edited are described in detail in Place.
All the tools and commands available in 3D mode can be used in both cases (see Working in 3D Mode).
