![]() ![]() Often your models will appear somewhat boxy and dull. ![]() They are really great at capturing manufacturing data (like mass, weight, etc.) but they can also be fairly restrictive in what you can create. Solids have many benefits, but there are inherent limitations there, too. But a surface model defines only surfaces, so it is hollow. You can create any shape you can imagine (given enough time and practice). This is somewhat tedious because you generally must build one face of the model at a time, trimming and manipulating as you go. (You can’t really measure it accurately.) You can build your design with surfaces. Easy to do and valuable for initial concept work, but not very versatile or informative. You can do everything on a napkin sketch. There are many ways to arrive at your ideal design destination. But SOLIDWORKS helps you with that by giving you tools that are easy to use and very powerful. You usually need to make countless small changes-no matter how great the concept. It’s very rare that you design something and get it right the first time. Why would you want to do that? Repeatability and changeability. In this way, you can capture design intent. It is parametric, which means you assign dimensions to your geometry that tell it how to behave. SOLIDWORKS, as you might gather from its name, is primarily a solid modeler. ![]()
