On a copy of your pipes in a geodatabase create a geometric network of your pipes. Make the network with complex edges.  this should then create a network junction at each intersection. Then export the network junctions as something else and you will have a set of points at all intersections. Remove the network.  Create it again with Simple junctions.  Select by Location the saved complex junctions with the simple junctions.  Where there is an intersect that is where the actual intersections are.  Delete the matches and you will be left with a set of points where two pipes cross but are not connected. It would actually take you a less time to do this than it took me to type it. ... View more

You can only export points, polylines and polygons (which may show up as closed polylines) the symbols you see in your GIS Session are a part of the definition you have in your MXD Hello, I am trying to convert a shapefile/feature class (Arc 9.3) to send to someone with AutoCAD 2007 (.dwg). I would like to check the output before sending it off, but I do not have AutoCAD to check to see what it looks like after the export. When I bring the .dwg file into Arc to look at it, all the attributes are gone/different from the original shapefile. Is their a way to preserve the attributes from the original shapefile when exporting to CAD? I can not use the Service Pack 1 that is referenced in previous threads, as I do not have AutoCAD on my machine. Any help appreciated! ... View more

I just tried it on a joined table and it does work. You can dynamic text off an attribute from a joined table. ... View more

I have not tried using a joined table but I do not see why it would not work. Worth a try. Let me know if it works. Thanks for the feedback! I wonder if it would work with a Join? Did you try that before you addded your feature attributes to the data driven pages layer? ... View more

Curious. You should not be able to place flags except on the network. Do you have multiple networks in your instance? I just tried it to make sure and it is only allowing flags to go direct onto a network feature. If you have multiple networks active you need to select from the drop down menu which network you are trying to place the flag on. I have a script tool that uses the Trace Geometric Network tool with a feature set as flags to allow user defined flags.  I use the Snap_edit to make the flags coincident with the network features. I want to be able to tell the user in a message through validation if their flag is not coincident with the network, instead of the tool failing while the trace is performed and gives  a " ERROR 001191: No flag found from the flag junction feature class". What's the best way to identify if the feature set is coincident with network features within the tool validation?  How can you tell if the SNAP_EDIT actually snapped to anything? In an ideal world, the flag would not be allowed if it wasn't coincident (like the add-in tool). Thanks in advance. ... View more

You can use the dymanic text function but in only works on the data driven page.  We wanted to do the same thing based on TWP RNG Section and Parcel Name(s) I simply built in those attributes to the feature I used for data driven pages and do dynamic text from that. Here is what I am trying to do: I am creating a map book that has data driven pages enabled and shows an aerial photo and building locations. What I would like to do is add an attribute table to my map layout which shows 2 attribute field values for the buildings layer. In this attribute table, I would only like to display the features located in that particular grid section. I believe I would have to use some sort of dynamic text in order to have the table change for each page. The data driven pages is enabled for my grid layer, not the buildings layer. I do not know if this is even possible and I am having a hard time solving this problem. Any advice would be appreciated! ... View more

Do you have to do it in Javascript? Is this only a one time deal or an ongoing process? Hello, I am trying to take a map extent coordinates (in State Plane), and convert them to pairs of Lat/Long coordinates.  I am getting a 'wkid is null or undefined' error during the geometry service project function. My code: function getCoords {     var topLeft = toLatLng(map.extent.xmin, map.extent.ymax);     var topRight = toLatLng(map.extent.xmax, map.extent.ymax);     var bottomRight = toLatLng(map.extent.xmax, map.extent.ymin);     var bottomLeft = toLatLng(map.extent.xmin, map.extent.ymin);     [...] } function toLatLng(x,y) {     var pt = new esri.geometry.Point(x, y, map.SpatialReference);     var symbol = new esri.symbol.SimpleMarkerSymbol();     var graphic = new esri.Graphic(pt, symbol);     var outSR = new esri.SpatialReference({ wkid: 4326 });     try{         geometrySvc.project([graphic], outSR,  // this is where it fails         function (features) {             pt = features[0].geometry;         });     } catch (e) { alert(e.message); }     var retv = pt.x + "," + pt.y + ",0";     return (retv); } Any advice is much appreciated ...

Well I can say you didn't choose a simple polygon to have an accident with. Ok multi-part fix but it should work. Multiple solutions. First make a copy of your polygon layer Working on your copy. now select all the polygons around the moved polygon.  Merge them together. Select  your bad polygon and reshape it so it is a big rectangle around the place where it should be. Select the merged polygons and clip the new rectangle. Keep the part in the void. Now you should have a polygon that perfectly matches the spot it used to be.  Now copy and paste the new polygon into the layer it came from and get rid of the moved one.  Make sure all the attributes came with it. It will take you a lot less time to do this than it took me to write it. Second method.  Redraw it.  as I pointed out not a simple polygon. Make a copy of the polygon layer as previously stated and merge the polygons together. However you can trace it pretty easy.  Move the moved polygon off to the side. Select the polygon merge that is around your void.  Use the trace tool to draw the replacement polygon in.  This may be fraught with minor difficulties but it works pretty well.  Copy the attributes from the old polygon to the new one and delete the moved one. Dear community, I'm a beginner with ArcMap and I'm working on administrative boundaries for my country. Anyway while editing the polygon I've accidentally moved it for a few cm/inches and saved the work without noticing it so I can't undo it. How to i glue it back with the existing vertices? I tried to move it manually with maximum zooming but even if they're aligned visually their vertices aren't glued. Here's an example of the map: [ATTACH=CONFIG]24738[/ATTACH] ... View more

Why cannot you simply copy them from the wrong layer to the correct layer and then delete them from the wrong layer. You can select the features that are in the wrong layer and right click on the feature in the table of contents and export that feature as a new feature and then delete them from the wrong layer. Hi, it might be a stupid question but how do i create a new layer out of selected features in Arcmap? I have drawn some polylines in edit mode while a new created empty layer was active and i thought those lines would automatically be drawn into that layer. Well, they aren´t and i now can´t copy the features into that layer either. So now i have some polylines in my project which don´t belong to any layer. So i hoped there might be a tool that lets me create a layer out of the features i´ve selected in Arcmap. Hope i could outline my problem. Thanks for your help! ... View more

I am looking for a way to return scale in an ArcGIS session. Possibly by putting it in a dynamic text box in layout. Or better yet to write it into a Definition query. The query would be something like only show this feature if the scale is less than (or greater then) the attribute (the attribute would have desired scale) Essentially. I have an attribute I call VisibleScale.   I populate it with scale values.  1000, 2000, 15000 etc. The definition query would be such that if the current scale value is greater then the VisibleScale Attribute then the individual feature would not be visible. mmh sorry I don't understant your problem... can you explain it better please? ...

Create a new database with a feature dataset in the coordinate system you want with some features from the new coordinate system you wish to be in. use the data loader to load the Zambian map into the feature dataset.  ArcCatalog will automatically convert the map to the new projection. I have a Zambian map in local coordinates in meters and would like to convert them UTM. How do I compute the conversions. I totally have no Idea. Please help? ... View more

Find and Replace cannot find nothing. You need to do a query using Select by Attributes.  The use Field Calculator or the Attributes window to insert a value. NOW I do not recommend this. You can also open your database in MS Access.  Open the table that contains the <Null> values you want to replace. Press Control H to bring up the Find Replace.  Insert the word Null and have it match Whole Field.   This way you can replace many thousands of null values with something. Now I must as why you want to get rid of the null values?  Is it only because you do not want to see the null value but would rather have a blank space. Keep in mind when you replace a <null> with a value you are increasing the size of your database and it could effect performance if you do enough of them. I am trying to replace a <Null> value in a selected field. When I do a find and replace I get an error that no fields have been detected. I have put in to find <Null> and replace it with the info that I want. I have selected the field but I still get this error. Can anyone help me with this? Is there a better or another way to do this? It just takes too long to select each field and type in the replacement info. ... View more
