Good morning everyone-
I'm trying to create a sanitary sewer lateral layer in my geodatabase and I'm running into a bit of a problem. Ultimately what I'd like to do is this-
All of my assets, sanitary & water are all Gps'd and I have positioning of the laterals. How is it that I can create polylines that go directly from the GPS'd lateral locations to the existing sewer line and have it be a 90 degree angle? I've been editing and drawing the lines by hand but they're just not 100% correct. If I can get 90 it would be more accurate and better for anyone.
One of the sketch tools in the drop down menu is Right Angle. It will only allow you to create lines at a right angle.
HOWEVER to make it work for your preexisting lines you will need to start at a vertex that is NOT the one at which you wish to make the right angle.
Here is a simple procedure. go to the line you need to make the lateral. I will call it pipeline
have your snapping set to line and vertex (or whatever your GPS point is)
start off a little away from the lateral point and start your lateral. for the second vertex in the lateral click on your gps point. then go off in whatever direction you want. when you are done with the lateral you will need to delete the first vertice.
A second way is if you know the exact angle of the original pipeline you can use the COGO drawing tool to specify exact angles.
Once you have your first lateral off the pipeline you can then use the cogo tool to accurately and easily draw in the rest of your lateral to where is it going. Very helpful this if you have other elbows that are not 90 degrees.
Keep in mind though that your GPS point will probably be off by anywhere from a few inches to many several feet. Depending on the quality of your GPS unit and the method used to capture it.
I don't see any available options for right angle from the drop down, is this the sketch tools (editor tool bar with the pencil icon)?
Yes, the right angle tool can added through customize dialogue.
It's for creating a line segment at a right angle to a previous line segment. But isn't that tool to make sure that your features are 'squared off' from one vertex to another. For drawing features such as Building sketches for example? I had thought the OP wanted to create lateral lines that connect to sewer mains. I figure since lateral lines and sewer mains are very different features they wouldn't be in the same FC...
Yes, I see now, that does make more sense. But if it needs to be 90 degrees (perpendicular) to the sewer main then wouldn't you still need to get reference to the sewer line you are connecting to? And you would have created an extra piece of line too.
Well, hopefully between all the responses the OP has already figured it out.
Well, as usual there are several ways to get to the same end result. Think that I would prefer to just snap to the GPS point and then snap to the sewer line using the perpendicular command (CTRL + E). Without having to delete the first vertex. Either way, I like the other idea too, I wouldn't have thought of that :) Thanks.
