GeoScripting outdated?

Uwe65 — Tue, 17 Feb 2015 21:28:17 GMT

Hello,

in the Bentley Map Help Documents (Version 08.11.09.107), Section Scripting > Using Scripts > Script Variables > Built-in Variables > Feature, I found the following statements:

"Only feature codes defined in the FCODE column in the FEATURE table are allowed."

One code example line there is: FEATURE = "3.1.1"

I was sure that in Bentley Map, there is no feature table any more (I know there was one in GeoGraphics). And there are no feature codes. There should be a XFM Schema instead, containing the feature names and definitions. So how do I assign a feature using this GeoScript command? I tried it using a feature name from the Geospatial example XFM Schema, but it didn't work.

This leads to the next question: is Geoscripting outdated? Or are those scripts (and the examples provided in the help docs) up to date and working all in all in Bentley Map? If they are outdated, which parts can still be used?

Regards, Uwe

Trouble with Dynamic Feature Scoring (DFS)

Uwe65 — Mon, 09 Feb 2015 21:51:17 GMT

Hello all,

I try to use DFS in a really simple structured project with only a few features. Here's an example: a linear element (line, line string) on Level 2 which is blue (color 3) should be designated as "my.feature". I tried the following syntax in my dfs.xml file:

<Feature useCriteria="" name="my.feature">
<Rule type="CExpr" score="1">XFMCompareElementLevelName("Level 2")</Rule>
<Rule type="CExpr" score="1">XFMCompareElementColor(3)</Rule>
<Rule type="Element" score="1" ElementType="3-4" checkZeroLengthLineElementType="false"/>
</Feature>

</FeatureScoringRules>

MS_GEOXFM_NO_LEVELFEATURES and MS_GEOXFM_NO_CELLNAMEFEATURES are turned off, because I'd like to control what happens in my dfs file. I don't like any features to be assigned by just by level or just by cellname.

In addition, I renamed the file FEATURESCORING.XML which is automatically created by the GSA system during the export process. My goal is to make it inactive this way, so I renamed it to .xml_. What I don't really understand is: if there are two dfs control files and both are recognized by the system, there is a chance that they have contradictory contents. Which one is evaluated by Bentley Map in that case?

Now, when I open a dgn file using my above dfs I expected the existing elements that reach the minScore of 3 as well as new elements to turn into native "my.feature". Instead, I find two things: first, none of my existing blue line strings on Level 2 turn into features. Second, if I digitize new lines on Level 2 in blue, they become "Inferred feature: my.feature". But, the system doesn't care what element type they are!! That is, a blue circle or a blue text on Level 2 also becomes "my.feature", which makes no sense. The syntax I used is exactly like it is explained in the "Bentley Map-DFS Notes.docx" document.

It seems to me that the dfs is working in principle, being the problem that the rule type "Element" is always considered true. If I set the minScore to 4, then no new elements become features any more.

Any ideas? Thanks in advance, Uwe

setting directory for Shape import

Uwe65 — Tue, 27 Jan 2015 21:34:14 GMT

Hello,

there was an old forum entry concerning exactly my question: why does the variable MS_GEOIMPORT_PATH not work? Using this variable, I tried to determine where my shapefiles and my .impx can be found, but this setting has no effect. I still have to navigate from some strange directory to my files. The forum answer was, that another variable defines the import directory: MS_GEOPROJHOME. I found that this is true, but changing this variable seems to be confusing for the system: my database is not opened automatically (like it was before). I have to undo the change, then my project is loaded correctly again.

Generally, I don't understand why there is a variable with a name sounding like exactly what I want, but it doesn't work. And there is really not much to be found in the Bentley Map documentation.

Any ideas? Thank you very much.

Regards, Uwe

Bentey Map Import shapefile and create database table

RTScott — Wed, 28 Jan 2015 15:46:03 GMT

Back in Geographics days I could import shapefiles and it would create the database table with the mslinks. How do you do this with Bentley map? I've been through the import routine but can't figure out how to create the table and populate it and assign the mslink attribute.
