Creating basic objects: curves, surfaces, and solids

In this movie, we'll be exploring some of the basic types of geometry, starting…with Curves and Lines, doing a few samples of surfaces, and then ending with a…few different types of Solids.…It's just for practice.…Let's begin by going to a brand-new file, File > New, and I am going to select…the Small Objects - Millimeters.…I'm going to do a lot of my work in the Perspective Viewport.…Let's go ahead and maximize that by double-clicking the label. Zoom out a bit.…Start off with one of the straight lines.…

We have a Polyline and Line Segments.…So, let's try right-click to do Line Segments. Take a look here now. This shape…has individual segments that are touching but not joined, so that's the…definition of a Line Segment.…Let's go ahead and do a similar version called Polyline, which is the…left-click option here.…Now when we select this one, notice that all the segments are joined.…

That's the only difference between Segments and Polyline.…One nice feature is you can go ahead and join those together with a joint…
