I am very close to completing the interior model of the kitchen, to add one more level of detail I have drawn curtains using the ruled mesh command, formally known as the ruled surf command. To demonstrate I will orbit about the model and show you how I am using a mesh to create the appearance of a curtain. I will begin by isolating the curtain and wind frame layers, clicking on the layer isolate icon and then selecting the objects. I will now enter. As you can see I have splines in three places, what I am going to do is connect the splines using the ruled mesh command and that will create the necessary meshes. Let me show you how I created the splines. Clicking on the polyline icon I began drawing a polyline with ortho off in a zig-zag pattern, I'll tap the escape key and continue. I need to convert the polyline to a spline, I usually type PE and then enter, but I want to show you that I can right click and go to the modify 2 toolbar and select the edit polyline icon. I will now select this polyline and I will click on spline, I'll tap the escape key and continue. At this point it was a matter of taking the spline and putting it in place. What you can also do is select the spline, hover over the grip points and move them in or out. This may add a little bit more detail to the curtain and make it appear a little bit more free flowing. I can delete this now and continue with the splines I have in place. Now I did not create all three splines, I simply copied this first one down and scaled it by 50 percent. I'll show you very quickly how I can copy that spline, move it down with ortho on along the Z axis and then select scale, select this endpoint and use a scale factor of .5, I then highlighted that spline and moved some of these grip points in or out, just to vary the pattern. At this point I am going to turn off or isolate the curtain layer. Now I can proceed to create the mesh, from the draw pull down menu, going over to modeling, down to meshes and selecting ruled mesh. I am prompted to select the first defining curve and I will pick this one here, I now need to select the second defining curve and I will pick this one. Notice how I am selecting from similar endpoints. That's the mesh but it lacks a bit of detail, so I am going to delete the mesh and type in a system variable. This is surf tab 1, I will now enter, the curve value is 6 and I am going to change that to 24. I am also going to do the same to surf tab 2, just to be consistent. The higher the value the greater the density of the mesh and now I am going to repeat the command. I will right click, go to recent input and select rule surf. Notice it doesn't say ruled mesh because it was formally known as the rule surf command, selecting the first defining curve and then selecting the second defining curve. I will repeat this, I am going to hold down the Shift key and tap the spacebar so that I can select the curve, now I can release the Shift key and click on this spline and then click on the second spline. Now I will click on layer previous, show you the window and how that curtain appears relative to the window. At this point it would be just a matter of mirroring the meshes to the otherside. You can decide to keep the splines since they are no longer needed or save them to use on another window opening. I'll remember you also as the surf tab value increases so does the mesh density and the file size. Once I complete the curtains I will provide this drawing in the tutorial.
