Hi there Is their away of setting a shortcut key for changing the tracing offset when editing in 10.1? Previous versions of Arc used the TAB key but this shortcut has been discontinued. The longer alternative is to type in minus [ - ] in front of the numbers in the tracing options box. However I have noticed a couple of things with this which I think could be considered bugs. 1. Type in -1.5 into the tracing box; 2. Go back to the tracing options window and the minus sign will have disappeared and all you see is 1.5; 3. Now type in -2. Instead of it moving further out in the direction of the initial -1.5, it swops over to the opposite direction of the line. The reason I might do number 3 is if I find -1.5 is not enough offset. If the above is designed as ESRI intended then I find it very confusing and not helpful. If others consider it to be a bug, I can always contact ESRI to file it. Kind regards Tim ... View more

Hi there I may have asked this before but I'll ask again since 10.1 is now out. I have a feature class with over 65,000 rows of data. This is stored in ArcSDE 9.3.1, hosted in Oracle 10gr2. I am using ArcMap 10.0.4 myself. Each row should have a unique feature id. Sometimes features need to be split into two and what I have now found, having done a distinct query on a copy of the feature class in SQL Developer, is 26 rows of duplicated ids. Is there anyway to stop this from occurring? In Oracle itself I can simply apply a unique key constraint but I've yet to find anything in ArcMap or ArcSDE to stop this from occurring. Is their anything available. Kind regards Tim ... View more

Hi there I am currently doing some data comparisons in ArcMap 10.0.4. The data is stored in ArcSDE 9.3.1 which is hosted in an Oracle 10g R2 database. I have three tables joined together, although I am only making comparisons between two of them. The one of the joins is not indexed but that should only affect the performance. They are joined so that only matching records are displayed. The tables are: Street_POLYGON LLPG ADDITIONAL_DATA The tables are versioned and out of those only the Street_POLYGON table has archiving applied. When I do the following select by attribute query though: "USER1.Street_POLYGON.STREET" <> "USER1.LLPG.STREET" I get the error: Underlying DBMS error [ORA-00904: "V__5111.STREET": invalid identifier] [USER1.DBJoin6] Now I have not set up any tables myself with the names V__5111.STREET or USER1.DBJoin6. Going directly into Oracle via SQL Developer I cannot locate either table in the database. These must have been created by SDE from the joins I made and perhaps on the fly. Can anyone tell me what might be causing the issue? I'm clearly using identifiable names when I do the joins and type in the names. Kind regards ... View more

Hi there I am currently working on a project which involves digitising streets in the UK ans I am using ArcMap 10.0.5 with the data hosted in a 9.3.1 SDE Geodatabase located in an Oracle 10g environment. Each street has a unique street reference number [USRN] and a name. However some streets are also classified as A or B roads. Until recently their were no USRNs for A and B road numbers but these have now been introduced. Could anyone tell me what would be the best way to group the roads into their A and B classifications, whilst still keeping them separate at their bottom level within the SDE geodatabase environment. I'm looking for an object object oriented model. So A roads / B roads / unclassified would be the parents and below them would be each road, which would inherit the properties of the parents but be separate entities in their own right. I've come at this from the bottom up because until recently their were no USRNs for A and B roads. Kind regards Tim ... View more

Hi there Currently when creating; reshaping or cutting a feature, there is only one sketch colour. It would be great is the sketch colour changed according to the tool being used. For example: Green could be create red could be reshape blue could be cutting. Of course the colours could be customised to suit ones own use. Currently I may accidentally attempt to reshape a feature when I meant to create a new one and not notice until after I've finished sketching. At which point I have to have the sketch deleted because ArcMap doesn't allow you to convert reshap or cutting sketches to become create sketches. Kind regards ... View more

Hi there I do a lot of tracing and reshaping of digitised polygons in ArcMap 10.0.5. However semi-regularly I come across the following and can probably make it happen everytime if I wish. Is the following a bug or is it work as ESRI intended it to? 1. I  digitised a polygon. 2. Snapping is switched on and is on the tolerance is 4 pixels. 3. Next I choose reshape because I need to reshape a small section of it. 4. Now I add 3 points using the right angle tool. 5. Now I switch to the tracing tool 6. I click on the final point I previously added. Before doing so the point snapping box appears, to show I am close enough to the point itself for it to snap to it. 7. Now I start tracing and shortly stop. 8. Finally I finish the sketch 9. Now instead of the sketch finishing I get an error message: "The reshape line must have only one part in it" Why are two parts being created when all I wish to do is carry on from the existing sketch line? Of course at this point my sketch is deleted and I must start again. Of course it always takes up to 10 seconds for a sketch to be deleted after an error, where as if you delete a sketch yourself normally, it's far far quicker. Less than a second. In fact this extended waiting also occurs when you get an error message when trying to save your edits. If they save OK it is far quicker than if they don't. It must be due to the way ArcMap handles error messages. Is this the same in 10.1? UPDATE: I've found another quirk as follows. 1. If I select a polygon and then move the layer into a background mapping layer, it will rightly no longer be selectable. 2. Next I start a reshape session on another polygon which I have selected. 3. Now I move the first layer out of the background mapping layr 4. Now I trace a reshape 5. I finish the sketch 6. Now I get an error message saying: "The reshape task could not be completed." However instead of it then taking 10 seconds or so to allow me to continue, it simply goes straight back to the editing window within less than a second. The same amount of time it would take if it had finalised the sketch and reshaped the feature. Why the after effects of the other error messages can't be this quick I don't know. Kind regards ...

Hi there The other day I installed PerfQA_Analyzer for ArcGIS Desktop 10. I am running Editor version 10.0.4 of ArcMap. Everything was fine until today. When I start an edit session and right click on a feature to use additional options, no menu is coming up. This was only resolved by the uninstalling of the above program. I can right click on menus and other parts of the screen but not the map part. Whether it affects other functions beyond just editing I don't know but if so it appears to be anything in the map window. Has anyone else come across this or know why it would occur? I've not actually used PerfAQ Analyzer yet. Therefore I don't fully understand how it works and how to use it. Would I have done something in the program to cause this behaviour? Kind regards Tim ...
