In which case you need to set your system units to Centimeter. Do you want density in grams/cubic centimeter or pounds/cubic inch I typically operate with densities in g/cc. Moreover, you or anyone on your team can pick up and work on a direct 3D product with minimal ramp-up time. I use Creo Elements/Direct 18.1 A few things not mentioned should be clarified. So, bring on your most radical design change or that one-off product: the software is intuitive, robust, and up to the task even with massive assemblies. At least one Creo Elements/Direct License Server is required. Creo Elements/Direct Modeling is the most comprehensive direct modeling system on the market, with a full range of extensions to meet your specialized needs. With direct modeling, even those who are infrequent CAD users can make changes to geometry quickly and easily, while CAD experts appreciate the direct modeling flexibility to design large assemblies in record time. In fact, most companies add 3D modeling to their product design process to help them shorten time to market, meet customer demands for new products, and satisfy increasingly complex customer requirements. PTC now has parametric modeling Creo (Pro E) and direct modeling Creo Elements direct (CoCreate). Direct modeling allows you to quickly and easily create one-off designs or radically repurpose existing designs-even if you don’t know how they were made. Creo Elements/Direct Modelings direct approach to 3D design is ideal for companies that need a lightweight and flexible design strategy to shorten design.
