Creo Layout is the Creo App for 2D conceptual engineering. Many companies, even though they use 3D solid modeling as their preferred engineering tool, still maintain some 2D CAD in house. In this case, what they want to do is take advantage of the flexibility that 2D CAD offers them; being able to make large, unpredictable changes and explore multiple design options.
WHAT IS THE TRADITIONAL CHALLENGE OF USING 2D AND 3D?
The challenges that many companies face when they use both 2D and 3D is that these tools are fundamentally disconnected. The design that is created in 2D, in order to be reused in 3D, has to either be imported or recreated into the 3D tool. This disconnection causes inefficiencies in the design process.
