No liability is assumed for incidental or consequential damages. Introduction to AutoCAD. Computer Aided Drafting. Autodesk is the most popular drawing program. Many student versions available for free online at. To do this, we first need an alignment, which can be created from a polyline. Click a point in the river to start the line, and then follow the meandering river, clicking along the way to add new vertices as seen below. Do your best to follow the low points of the river.

In practice, you would probably want to pick a more refined way of tracing the river route, but we will just create the alignment manually here as an example. Left click on the polyline to select it. Note: if you made a mistake, you can either edit vertices with the polyline edit tool type pe or you can delete the polyline and start over.

Make sure you are viewing the Ho e i o. AutoCAD will ask you to verify the direction of the alignment. As seen below, it will show an arrow pointing in the direction look at the middle part of the polyline. Because we drew the alignment in the direction of the flow, it should be oriented correctly. It is important to know the direction of the alignment, as it will help you make sense of the profile. After you have created your alignment, you can label the stations in your plan view to help you remember the orientation.

This is left for you as an exercise on your own. After you confirm the direction, a dialog e titled C eate Alig e t f o O je ts ill e displayed. Make sure your screen matches the following graphic and hit OK. The alig e t is o eated. You a o fi this looki g at the P ospe to ta i ou Toolspace. You now have created a surface and your alignment for the river route. At this stage, the two a e disjoi t.

He e ou a sele t hi h alignment and which surface you want to use in this operation. In a real project, you would likely have many alignments e. In this example, there is only one alignment and one surface. The hit OK to sa ple the su fa e alo g ou i e alignment. You have sampled the surface along your alignment and are now ready to generate a surface p ofile. A C eate P ofile Vie — Ge e al dialogue ill e displa ed.

If not, then you may not have successfully sampled the surface along your alignment Step 25 or you did not select the correct alignment Step For this exercise, we will not worry about the style of the profile, so we will just continue through with the default alues.

AutoCAD will now prompt you to select a profile view origin. Click at your desired location to place the profile. The profile will be drawn automatically for you, as shown below red line is your surface.

There are some jagged areas, which may have resulted from a variety of reasons: 1 we eyeballed the alignment, 2 there may be low points or rocks in the river survey, 3 there are locations without many survey points where we are viewing the interpolation. The profile tool is a useful way of looking at slices of your surface, which should inform your designs. Note that you can also use this tool to generate cross sections e.

It is left as an exercise for you to create a cross section of the river. Autodesk is the company that is behind the development of AutoCAD book pdf and who has kept it on the market since AutoCAD is a complete software it is a monster that can scare the first glance, but with the right orientation, we assure you that anyone with a little practice can get along with it and make their own designs.
