To be perfectly honest I didn't even know about the perpendicular command until you mentioned it. I guess I had seen it in when you right click but it isn't something important in the way we create our GIS system and whenever this kind of precision has been required I use the COGO toolbar.  Good to learn something new.  There are so many thousands of functions available. However, I was think about this last night and came up with an idea to draw in the laterals by the thousands that really would be a little complicated it would require a lot of precision, and it may not even work until tested. and would require some sort of extra data in the GPS point to indicate which direction you needed to go. 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. ...

Yes this way uses the existing line as a reference for the direction in which the pipe is going.  You would have to delete the first Vertex of the lateral. HOWEVER, once all the laterals were drawn in you could select them all and use the bulk snap command to snap ENDS to the GPS points that were used to draw them.  If you first segment is only a couple of feet long you could set the tolerance to 3 feet and bulk snap them.  Just be zoomed in close enough that you would not snap things you don't want snapped. Robert, 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.  Best Regards, Sol ... View more

The way I wrote to do it by starting on an edge of the existing line and then you click on the GPS point where the lateral is it will then only allow you to go in two directions each of which are 90 degrees to the direction of current digitizing or drawing.  So if you line is heading off at 93 degrees and you click on an edge and your next click is on the lateral on the line it will then only allow the next segment will be at 3 or 183 degrees Yes, the right angle tool can added through customize dialogue. http://help.arcgis.com/en%20/arcgisdesktop/10.0/help/index.html#//001t00000065000000.htm 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... ...

Use the Explode Tool instead.  They are multi part features.  Explode will separate them out. In fact you can select ALL on your streets and run the command and it will automatically separate all such features. Hello, I am working on editing the street (line) features in a shapefile. I have a street that is in three separate segments but identified with one ID (See screenshot below). [ATTACH=CONFIG]31081[/ATTACH] Using the "split" editing at the ends of any of these separate segments results in the message: The feature could not be split. Split point results in a zero length polyline. The operation was attempted on an empty geometry. Any tips on how I may be able to split these? Thank you, David ... View more

It should be in your editor toolbar. If you cannot find it just open the customize dialog and in the show commands containing dialog search for right angle. If it still isn't there then you probably have an old version of ArcGIS and if you can then upgrade. 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)? ... View more

If you move the end point of the line it most likely will still be a closed polyline. You will need to manually split them to break them up. You could also try the explode function and see if that will get you anywhere. Here is an off approach fix. use calculate geometry to calculate the X,Y of the end points of each line. Then take those x,y locations and create point features from them.  BUFFER those point features into a polygon layer with a 1 inch buffer.  Select all those buffer polygons and clip the polyline layer.  Now of you have some that are NOT closed you can calculate beginning and ending x,y and and then only create the points on those features that have identical fromx, fromy and tox toy Sound arduous but the whole thing should take a couple of minutes.  ' I would recommend experimenting on a copy first. Hi All, I have a feature class made up of lines. Each of these lines are loops. Therefore they have the same beginning and ending xy coordinates. I am looking to move the end vertices for each line a known value away to disconnect each loop. I understand that through editor I can manually change the end vertices for each loop in sketch properties but I am looking for an automated way to move the last/end vertices of each line in my feature class the same known distance. Example: I move each line's end vertice 5 meters in the x direction and 5 meters in the y direction. Any guidance would be greatly appreciated. Thanks! ... View more

If you print from the Layout View it should only print what you have displayed in the layout window.   Provided your map page size and paper size are the same. ... View more

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. 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. Thank you. ... View more

To many variables to be able to narrow it down. 1. it could be that your machine is not powerful enough to handle a large number of calculations. 2. Polygon layers take more resources to export.  Annotation is treated as a polygon.  If your annotation is feature linked that takes longer as well 3. if your data is on a network that can make it take longer. 4.  pause the drawing while exporting.  This will free up resources for your computer. 5.  if your working in a geodatabase or SDE you should compress it 6 run disk defrag and disk cleanup on your computer 7  how much free space does your hard drive have?  If it is under 15% you should free as much up as possible.  and run defrag and disk clean up again. 8.  for your export settings.  Lower it down to 300 or better yet 150.  600 is good but that is a huge drag on the export.  Change the output image quality down to normal.  on the Advanced tab when exporting set it to Layers and Attributes to NONE and do not export georeference info Hi I try to export map with annotation with PrintingTools and I found export map with one  annotation layer  only takes about 1-2 minutes to A4 landscape pdf 1:2000 600 dpi. While export map with one polygon layer takes about 5-6 seconds and 5-6 different polygon and polyline layers 6-7 seconds also. Is there a way to increase the speed of export map with the annotations layer? BTW. Dynamic service vs feature layer from dynamic service. Map export to A4 pdf 1:2000 with operational layer from my dynamic service Hydrography  with one layer Sea  takes 76 seconds. Map export to A4 pdf 1:2000 from Feature layer Sea (map service) from this dynamic service Hydrography   takes 5-6 seconds.

We still use XP in my office. Our GIS Team will be the last to upgrade our office is only going to 7.  Windows 8 is fine.  I use it at home and it works great.  I installed ArcReader at home and brought home a database and pmf that i generated at work on an XP machine.  One of my clients wanted to get an 8.1 tablet and wanted to know if it would work.  which it did. There just have been to many problems with upgrading a system to 8 because the programs on your machine were not built for it. However, the same has held true for many previous upgrades so this isn't particular to 8.  When we upgrade to 7 next month we will perform complete installs. Thanks for the help. I am definitely NOT going to reinstall 8 :mad:. My computer was originally running 7 but I had problems trying to map a network drive (through a VPN) and was told that 7 did not have the capability so I would have to install 8. I'll figure out that problem as soon as I figure out where to re-download. I was hoping there was a link online somewhere but I guess I will have to call IT at school... ... View more

I guess it is to late to tell you to not upgrade to Windows 8.  Windows 8 is great, but it is better to not upgrade to it from 7 or XP as it typically causes issues. From what I understand you are only qualified for one student copy of ArcGIS Where did you get your first copy? Typically I thought students got them from their school. The main student download on the ESRI site is for instructors. If you have an ESRI Global Account you should be able to get a 60 day version here. http://www.esri.com/software/arcgis/arcgis-for-desktop/free-trial This might be what you had before. http://www.esri.com/landing-pages/software/arcgis/arcgis-desktop-student-trial I had a student evaluation version installed but now I have a huge problem. Because of a disaster with upgrading to Windows 8.1 I had to reinstall everything then a driver update caused my computer to go black. I am being forced to reload and reinstall everything. I cannot find where I can re-download ArcGIS 10.0. I have been wasting all morning on this. When I go to the student evaluation it asks me to activate mine but it doesn't show where I can download it. I have homework due and drastically need to get this reinstalled ASAP. Can anyone out there help me? ... View more

If you added them in an ArcGIS session why would you need to geocode them.  They should already be placed where you want them.  Typically geocoding is performed on a set of data that is not a shape file or feature class. I edited the shapefile to add the new records in an ArcGIS session. First I thought about exporting the shapefile to Excel and then add  the new records there, but I didn't do it. Because I thought the old records would lose their XY coordinates. So, after I added the new records in an ArcGis session, do I have to geocode the shapefile(table) again and use the new shapefile obtained from geocoding to make my map? . ... View more

I am not certain what you did but did you open the dbf in something like excel and add the records. You cannot do that with a shapefile.  you will lose everything or if you don't lose it you can scramble the data records.  The dbf rows are tied to a specific graphical feature. if you make changes to the dbf you alter which record is tied to which graphic. if you need to edit a shapefile you do it in an ArcGIS session. I am told to update a shapefile (add new records to it) before I can use it to produce a map. To update the shapefile, I opened its attribute table and then used "Start Editing" and "Add new features" option to enter the new records. As I updated the shapefile this way (by editing the table and adding the new records), I think that the XY coordinates were not lost for the old records. However, I am wondering if I have to geocode again the shapefile in order for the new records to have a positional location attached to them and then use the exported shapefile (obtained after geocoding) to make my map? Thanks. ... View more

Oh well then.  sorry I read in the beginning you were not sure you had it. First you need to create a TIN from your contours.  You should assign a projection to them.  use the Search in an ArcGIS session and look for TIN EDGE that will create the TIN from your polyline contours. Then search for SURFACE SLOPE and it will create a polygon layer for you from the TIN that displays Slope IF you could find a pre-existing DEM of your location in question it would be a little easier.
