AutoCAD WS offers many of the same hatch options found in the full version of AutoCAD. This means that anyone can create customized exhibits without the need for expensive software. In this lesson, we'll create an exhibit using some hatch patterns. On my screen is a drawing of a small subdivision Let's say that I'm a homeowner in this area, and I'd like to create an exhibit to take to a city meeting such that I can highlight some flooding that's been occurring in the subdivision. As you can see, there's a small river over here on the west side.
I'm going to roll the mouse wheel forward and zoom in a little bit. Now the problem is the city recently replaced the box culverts under these two roads, and when they were replaced, they were made larger. Now during heavy rain, the smaller culvert under Sycamore Lane cannot accommodate the extra flow, so the river backs up and floods these five lots and these four. To highlight the lots that are experiencing flooding, I'm going to use some hatch. First, I'll make a couple layers.
I am going to move up and click the Manage Layers icon. I will then click New layer, and I'll create a layer called flood-lots, and I'll set the layer color to magenta. I will then create another new layer called flood-problem area, and I'll set the color of this layer to red. I'll use this layer to hatch the box culvert causing the problem. Finally, I'm going to select the flood-lots layer.
I will click the green check to make it current, and then I'll click the X to close the Layer Properties Manager. To create the hatch, I'm going to select the Draw tab, and then I'll click the Hatch tool. This brings up a context-sensitive tab containing the available hatch options. If I click this flyout, I can choose from the extensive list of patterns. For this exhibit, I'm going to choose ANSI31. I will then click the flyout again to close the menu. Using these options to the right, I can select a color for my Hatch pattern, I can also adjust the Hatch pattern scale or rotation.
It's important to note that when you create hatch in AutoCAD WS, there is no preview. So I'm going to guess that a hatch scale of 20 is going to look like what I want. I will then move down into the drawing and click inside this lot, and this pattern is a little too dense. Unfortunately, I can't change the pattern I just put in. That's all right, though. I'm going to keep going. Let's try a hatch scale of 50, and I'll click in the next lot. Well, I'm getting closer. I am going to try a hatch scale of 90, and I'll click inside this lot.
This is exactly the look I want, so I am also going to select these additional four lots on the north side of Sycamore Lane. When I'm finished, I'll move up and click the X to close the Hatch tool. Now to fix these incorrect hatch patterns, I'm going to move up and launch the Match Properties tool. I will then click to select a good hatch and acquire the properties. Next, I'll click on each pattern I'd like to correct. When I am finished, I'll press Enter. To hatch these remaining two lots, I'm going to re-launch the Hatch command, and as you can see, AutoCAD WS remembers the previous settings.
I will then click inside this lot on the north, and I get a message that a closed boundary cannot be determined. Now this doesn't mean that I don't have a closed boundary, it just means that WS cannot recognize the closed boundary. That's all right. I'm going to click OK. Fortunately, when this drawing was created, each of these lots was constructed using a closed polyline. So I'm going to move down and change the Hatch Method to Hatch Select. This allows me to select a closed object. I can then press Enter to apply the hatch.
I will then select this last lot and press Enter, and then I'll click the X to close the Hatch Tools. Finally, I'd like to highlight this area that's causing the flooding. I'll start by using the Zoom Window tool, and I'll select that area, and I will then pan this to the middle of the screen. I will then open the Layer Control and set the problem area layer current. To highlight this area, I'm going to draw an ellipse. So I'm going to move up to the Draw panel and launch the Ellipse command. I will then click to the upper-left of the box culvert, and I'll come down here to the lower-right.
In the event I'd like to center this shape a little better, I will click to select it, and then I'll move up to the Modify panel and click the Move tool. I will then click to pick the object up from a point out in space here, I'll move it over and click again to center it a little better. Knowing what we know now, we can easily hatch this shape by launching the Hatch command, we can then adjust our properties. I am going to stick with the ANSI31 pattern, I am going to change the scale though, I'm going to cut this in half, we'll make it 45, and let's change the rotation as well, I'll make this 90.
I will then choose the Hatch Select method. I'll select the ellipse and press Enter. Now that I'm finished with my exhibit, I'll move down and do a zoom extents, and this drawing is now ready to be taken to the meeting. Using the Hatch tools in AutoCAD WS virtually anyone can create customized exhibits without the need for expensive software. Likewise, with its easy excess AutoCAD WS could even be used to present those exhibits at a public meeting.
