Model a window

- [Instructor] At the stage, we have a series of rectangles…here representing the various details on the window…and we need to convert this into a 3D solid.…Let's begin by converting the polylines into regions…and then subtracting and then extruding,…so we'll start by typing R-E-G for region…and I'll select this rectangle and press enter…to convert it into a region.…I also want to convert the rectangle out here into a region…but it's ambiguous, because when I hover the cursor there,…it seems to select the wall rather than the green rectangle.…

So, in a situation like this,…where it's difficult to select things…because there are so many different objects there,…it's helpful to turn on selection cycling.…That's a mode that you can access…through the customization menu on the status bar.…Turn on selection cycling, not selection filtering,…but selection cycling, and that's this green icon here.…When I turn that mode on, it will behave in a different way.…So now, if I want to type a region, R-E-G, enter.…

If I click here now, it's going to open up…
