Trouble with Dynamic Feature Scoring (DFS)

RE: Trouble with Dynamic Feature Scoring (DFS)

Jerry,

thank you very much for your answer. I tried the promote tool in the Geoexample workspace with some existing features that have this method implemented. It works. But I have to featurize hundreds of elements in many files after they are generated or reviewed, same procedure every time, so it has to be automated in some way.

I tried to record a basic macro while promoting, but nothing happened. The command was not recorded. Does this mean there is no basic command for promoting?

Then, I tried the keyin browser, giving me a very strange outcoming: it offered the Key-in FEATURE ATTACH BEST! What does this mean? Is there a way to use a key-in for promoting? Command table outdated?

And again: what is the intention for DFS? If it is not to featurize existing elements like F Attach Best? I just don’t understand, sorry.

Mit freundlichen Grüßen,

Uwe Fischer

Uwe:
In response to your references to Geographics and the use of Feature Attach Best, and Active Feature tools. I believe using the Promote tool in Map can be used in place of the Feature Attach Best. This tool allows you to create generic elements and then later 'featureize' them. This tool works with selection sets, individual elements, and fences. You need to add this functionality to the feature definition in the GSA for the features you wish to 'promote'. Unlike DFS, this will create native features out of the geometry.

As for the fence create areas, once again there is no automatic way to do this. I again refer back to the promote tool to perform this functionality after the areas ( polygons) are created.

Jerry and Chris,

thank you very much for your answers. Jerry, let me please tell something about the workflow in which I try to use DFS. That might help to see what I'm trying to achive. We don't place native features the usual way via methods from the command manager. When our dgn files come from basic data collection workstations, they have no feature tags and no level names. There's just linestrings, texts and some cells on levels 1, 2 and 3. This situation can't be changed due to the software equipment on these PCs.

Now, we have to turn those "naked" elements into correct features to perform analysis, overlay and conversion into other formats. In GeoGraphics, this worked perfect using the "Feature Attach Best" functionality. My intention was to imitate the FAttachBest procedure using DFS with scoring rules. Is this possible? If not, what is the best way to native feature-tag existing elements in a file without level name definitions?

Another important question is: is there a way in Bentley Map to get new elements feature-tagged when those elements are created by the system using a command like "fence create areas"? In GeoGraphics, I had to set an "Active Feature" prior to the element generation. How does this work in Bentley Map? I didn't find something like "Active Feature ="

Chris, please see the example dgn file in the attachment. The blue linear elements on level 2 are the ones I tried to feature-tag as an example. The content of the according XML can be found in my first post.

Thanks a lot in advance, Uwe

Uwe,

Would you provide a simple example dgn with the old existing elements that are not identified as features?

Would you also provide an example (dgn & DFS scoring rules) of "In addition, I tried to append features to line strings that are not defined as linear features but as area features." ?

Regards,
Chris

Featues recognized via DFS are inferred features if they are not tagged as a native feature and thus are ‘inferred’ by their level and geometry type. To test this, place a simple line (place line tool) on one of the levels where a typical linear feature would be stored. This will then be a ‘inferred’ feature, because you did not place a GIS feature, you placed a line, but youplaced it ont eh level and with the geometry of the linear feature.

Chris,

thank you very much for your answer. Changing to "elementType" brought a little improvement : new elements that are not of the designated types (3,4) are not featurized any more. When I go back to "E" as a test, they are featurized. But my old existing elements still don't turn into features, and I have no "Native features" but only "Inferred features".

What can be wrong?

In addition, I tried to append features to line strings that are not defined as linear features but as area features. I know that this makes no sense, but I wanted to see what happens. It worked! So I am sure that something is wrong here.

Any more ideas?

Regards, Uwe

Uwe,

In your "Element" rule, would you try changing the "ElementType" attribute name to "elementType".

Chris
