When you open the AutoCAD drawing in ArcGIS does it come up in the proper geographic location? I would suggest loading something first from the area then adding the DWG. If it does then simply export the CAD features to a database. ... View more

most dems are not terribly high resolution.  I think you would have a difficult time finding a lineament on one.  You might have better luck with a high resolution Air Photo. If you have the proper extensions (3D Analyst) you could create contours from the DEM and try to use that to determine lineaments. If you happen to have Lidar data available for your area that  might be a better bet. See title! Much appreciated! ... View more

I have done this numerous times.  Start with something from your GIS that is in the proper projection. Sections work good because then you can easily adjust the CAD drawing to proper world location. Export the sections to a shape file.  Import them into CAD preserving the data and the projection.  Make sure your Shapefile has the .prj extension once imported lock the sections layer. add your autocad data as a block.  Move it to the sections that a locked. If you can this would be a good place to resize it and place it where it should go in the real world. save the DWG. run build and clean several times to get rid of the crud. save the DWG. Now you have choices. First add the DWG into your ArcGIS session.  If everything lines up they way it should (and it should) then you can proceed to strip the cad and export it to your database. Or you can export the DWG as a shapefile.  Save it to the original Sections shapefile you had imported.  This way it will give it the same projection as the shape file had as CAD will not export a .prj file without a predefined projection in cad. FYI, I have spent many hours converting AutoCAD drawings to ArcGIS and most of the DWGs either had no projection or were simply very wrong.  One system I converted was actually in the proper projection but whoever built it used millimeters or something to represent feet.  End result the system which spaned 30 x 50 miles was the size of third base when brought direct into ArcGIS Hello, I have some CAD data in an unknown local coordinate system that I have to get into a geodatabase in a State Plane coordinate system.  I have a CAD script that is currently being run to get do this from within AutoCAD, but I need to do this with Python instead now. I have some examples of the data in the State Plane coordinate system, but I am struggling as to how to find all of the parameters that I need to create the custom .prj file. The script currently does: 1. Scale all -> 0,0 -> 1/12 2. Move all -> 18766.832,11612.104 -> 2829031.998,1017487.369 3. Rotate all -> 2829031.998,1017487.369 -> -30.0916403 4. Scale all -> 0,0 -> 0.9999129 I am unsure as to the best way to get the Easting, Northing, and Latitude and Longitude of Center. I think that the rotation and two scalings can be done by setting the rotation, units and scale factor. It is the rest that I am struggling to find. ... View more

Use the Scale tool. If you go to customization type in scale in the commands area it is in the Editor Category This will resize your polygons without changing the shape. Just make sure you don't mess with the geographic center point.  it is the anchor. [ATTACH=CONFIG]28357[/ATTACH] as above image, i want resize polygon with no distortion. and, it is the best way using scale unit(like a x10, x1/4 etc..) how can i do this work?? please, tell me a solution! ^^ ...

I cannot remember how 10.0 appears but if there is not an Attribute option for the Dynamic Text simply add a data driven page name and open it's dialog up and change it in there. ... View more

Did you do Insert>Text or Insert>Dynamic Text>Data Driven Page Attribute that is important. I am running ArcGIS 10.0... using Insert-> text-> then editing in properties box - used the format you put down and still just gave me the numeric code. ... View more

It should work just fine. I just did it to try it out before responding and it put in my subtype as the value not the numeric code. What method did you use to insert the dynamic label? You should click on Insert>Dynamic Text>Data Driven Page Attribute. Then select from the drop down list your Subtype Field. It should look like this <dyn type="page" property="attribute" field="subtypeCode" domainlookup="true"/> I am creating a map book with data driven pages, using dynamic text with an attribute field with the help tip below...   TIP: With the dyn type="page" you can create dynamic text with any attribute field of the Data Driven Pages index layer. For example, if you have an attribute on the index layer named POPULATION, you can create a dynamic text tag using this field, <dyn type="page" property="POPULATION"/> to dynamically display the POPULATION values for each page in the layout. With this functionality if you have an attribute field in an index layer of your data driven pages you can use it as dynamic text for the pages I have tried it with a field that uses a coded subtype, and just the numeric code will show - is there any way to display the coded value instead?  Thanks! ...

Multiple options. 1.  Copy and paste your center line back into the feature you want it in.  then without unselecting it use the move tool to move it the desired distance. This will only work for perfectly horizontal or vertical lines. 2.  Start an edit session.  Select your center line  choose the trace tool.  Click near the beginning of your centerline.  then press "O"  the Oh Key.  This will bring up trace options.  Select your offset.  if you system is in meters convert feet to meters. then as you trace up the centerline it will draw a new line perfectly offset your selected features.  IF you have a gap it will stop tracing at the gap.  simply click at the beginning of the gap and at the end of the gap and continue tracing.   This will be a lot more accurate then option 1. 3.  Use the buffer idea from the previous poster.  However, if you have gaps this may result in concave areas if the gap is large enough. ...

Oh and then have your second data frame referenced to your main frame. as another poster recommended. This is very easy. And there are 2 simple ways to accomplish this. First determine the extent or scale you want to use. Create your data driven pages.  Set you DDP in the Definition Tab.  then select the Extent Tab. In the extent tab select Center and Maintain Current Scale.  so whatever you set your scale to before you start to export the DDP it will make maps centered on the polygon or point feature all at the same scale. Method 2 is less fraught with possibilities for error. Below the Center and Maintain Current Scale selection is a choice for Data Driven Scale. First create an attribute for your DDP feature with the scale at which you wish to generate your pages.  This attribute will have to be a number attribute (double or Long Integer)  .You can put in a scale for your index layer as well that will be different.  so if you want 1:24,000 enter 24000 in the scale attribute. Now when you export your pages they will all be at the scale value you enter into the scale attribute. ... View more

Oh now I see what you want.  First make your basic symbols based on the attribute that gives you the numbers you want. For this example I will use the value of 2 double click the 2 to open the symbol selector.  Select Railroad then click edit symbol you should have 2 symbol levels.  a  hash and and an unbroken line.  Select the hash and copy paste it as a new level and change the angle to zero. Now on the first hash select the template tab and make it look like Image1.  then do the same for the second hash. Now go to the template for the unbroken line.   Make its template look like image 2 Using the Template you can specify exactly how the line is broken.  For the values of 3 simply Expand the gray box that is at the end of the template line another 5 values to the right.  After the last set of black squares leave the first 2 white and the next 3 black.  Now expand the hash mark templates to the right 5 more values.  You will now have a line with 3 dashes between the plus symbols.  do the same for 4 or 5 or more, etc... ...

First take a point feature and create a symbol for it using a character.  such as the number 2.  Save As the symbol in your system. Then go to your line feature. Select a the dashed line symbol you want, with out the tags, just a dashed line symbol. Click on Edit Symbol click the plus button to add a layer From the drop down change the symbol type to Marker Line Symbol. Click on symbol and choose your number 2 Click on Template and move the slider bar over so you have 3 or 4 positions showing. Click in all the white boxes and make them black. That will create the dashed line symbol with the number 2 interspersed along it. Is there a way to create a line symbol with the number of hash represented by a number field? I am trying to represent the feet of head loss in pipe segments (regardless of length) with hash marks. I want the number of hash marks equal to the feet of head loss. For example, a pipe with a 2-foot head loss would be always drawn somewhat like this:  ----+----+--- ; that is, a line with 2 hash marks. Thanks. ... View more

Everything is on a server. It is odd to me and I am at a lost to explain why it takes so long . I'm starting to trhink it m,ay be more of a network issue. Anyway I've given up trying to export them out. I printed each one to a pdf individually. We have a hurricane bearing down on us and I have 14 different flood levels with 7 pages to each flood level. Can't waste time trying to figure out the export problem. Sounds like a network issue.  However, the more data you have in your layout the longer it is going to take. I have a particular project I export and there are a lot of things going on for each page and it takes upwards of 10 to 20 minutes to export a single page. You can speed things up by adjusting the quality.  Play with it a little bit.  Lower it way down and export review the quality and increase it until it is good. Use compression.  turn off all other programs when exporting.  Exporting to pdf can use up a lot of memory and other programs such a mail program etc chew up resources that ArcGIS could be using.  Pause your drawing while you export and turn off caching ...

On another train of thought. Using Data Driven pages. Have it clip the area that does not intersect your data area. If you have a polygon layer that you are using as your area of need you can re size it and re-run data driven page set up. Or you could base your data driven pages on a point feature and determine the diameter of the area shown and still clip. ... View more

Sadly it did not work.  I think if I had a more simple model it may have worked but I wanted to use the parameter as the beginning of 23 different sub operations. I don't really need the solution I just want it.  The model works fine IF I do the definition query to the Feature Class before running the model.  And as I won't have to run it to many times I can just remember to define the data first. If anyone else has any suggestions I would love to try them out. My model takes Transmission lines that are distinguished by Line Name (180 unique) Segment (23 different segments) and Circuit number (2 unique).  I then have 65000 poles some of which straddle segments and circuits.   What I am doing is extracting those poles and creating a new feature that segregates into grouping the structures by which line it is on and which segment and circuit.  and for those that straddle multiple segments and circuits it will create multiple structures.  Long story short I have the model working perfectly if I define circuit 1 or 2 and then run the model twice.  However, as I am doing this and finding drawing errors and fixing them and running it again etc etc... I was just looking for a way to streamline my process.  Not that it is a pain, I just want to know how at this point. ... View more
