Which option is used to create a new assembly in Solid Edge?

Creating a new assembly in Solid Edge is accomplished by selecting the 'New' option and then choosing 'Assembly'. This process initiates the assembly environment, allowing the user to add components, define relationships, and manage the assembly structure effectively.

The reasoning behind this option is that it directly leads to the creation of a new assembly file, which is essential for any task involving multiple parts. When you choose 'New', you are presented with the types of documents you can create, and selecting 'Assembly' signifies that you intend to work within the assembly environment, where tools and features related to assembling components are available.

Other options available do not provide a direct path to creating a new assembly. For instance, selecting 'Open' and choosing 'Assembly' would merely allow you to open an existing assembly rather than create a new one. Choosing 'New' and then 'Part' would lead to the creation of a single part file, not an assembly. Meanwhile, using the 'Import' function is typically used to bring in existing components or assemblies from other files rather than creating something new from scratch. Hence, option C stands out as the correct choice for creating a new assembly in Solid Edge.
