How to delete a feature which have lost its geometry (element)

Greetings Erik,

No standard utility exist for this so you will need to programatically remove the instance(s). If you are able to obtain the UUID for the instance you may be able to enter mdl command deleterootuuid nnn where nnn represents the UUID for the feature instance.

hello jeff, i have my own set of similar mdl command xxx .. so it is very interesting for me to know there are exist some "core" mdl commands like deleterootuuid, may i ask you for more information about this commands like a list of  these commands? ... thanks Jan

Jan,

As you might imagine, we have a number of internal commands used for diagnosing reported issues. These commands remain undocumented and unsupported due to their diagnostic nature and the fact that they change frequently based upon current support needs. However as a developer, you may find the following additional commands useful...

• mdl command showfeatureinfo
• mdl command showelementinfo
• mdl command showchangesverbose
• mdl command showallfilesdeletecache
• mdl command dumpchangesstore

...with each dumping various diagnostic information to the MicroStation text window. While most of the above commands do not write any information to your active design file (e.g. they only output diagnostic information) I recommend that you please use at your own discretion as they are unsupported and subject to change w/o notice.

jeff, thanks for your information

Jan,

Note that a few of these listed commands are documented in the "Change Tracker Summary" section of the Bentley Map Customization Guide.

Hi Jeff

I have the same problem of having features which show in the Databrowser without any corresponding spatial geometry.

I also have no programming skills and as you state that there is no standard utility to remove the instance(s) can you suggest what I can try to tidy up my data?

Greetings Anne,

You should be able to use the following workflow to create a new design file containing only the XFM feature instances that have geometries:

1. Create a new empty design file using the same seed file used to create the original design file.
2. Open the newly created design file in a new Bentley Map session.
3. Reference attach the original design file to the new design file and ensure that all levels of the reference file are displayed.
4. Perform a view fit command and make sure all feature instances are visible.
5. Place a fence which encompasses all visible graphics of the reference file.
6. Perform a fence copy command of all graphics from the reference file to the active file by selecting a single datapoint then entering DX=0 keyin to accept and begin fence copy processing.
7. Reference detach the original design file.
8. Load the Data Browser application and verify the results.

Please note that the above workflow should not be used if any of your XFM feature instances are being maintained in an Oracle Spatial repository or have external RDBMS linkages. Also make sure that you are not using any applications which generate non-graphic XFM feature instances (e.g. features w/o geometries).

Hi Jeff

That works well thank you.
