Map Industry Model Plot Extension

If you use Map Industry Model Plot Extension make sure that the layers in your main display model do not contain a spatial filter. A spatial filter is automatically created when you save a display model. In order to remove the spatial filter you need to open the .layer file in an editor and remove the filter setting:


<Filter>GEOM ENVELOPEINTERSECTS GeomFromText('POLYGON XYZ ((698785 258855 0, 700411 258855 0, 700411 260393 0, 698785 260393 0, 698785 258855 0))')</Filter>

to

<Filter></Filter>

It seems that Map applies the filter from the layer file when generating a Map plot. If the spatial filter does not match with the area you want to create a plot for the layer content will not be shown.

Oracle ANSI JOIN syntax improves peformance

Using ANSI JOIN syntax instead of Oracle Join snytax is recommended - see here:

http://www.orafaq.com/node/2618

We found out the hard way:

- a third party application issues simple but nested SQL statements against Map IM views
- for some views we noticed that the query ran for a long time and generated a time out 
- just by changing the JOIN syntax to ANSI join the issue was resolved

Map IM - generating graphics and DXF files

Recently we encountered two issues regarding DXF files and generating graphics. Both only happen if you enable "Reuse Active Drawing" in "Generate Graphics" application options.

1) Display Model is loaded into wrong drawing

If you have opened one or more drawings (DWG) and one DXF file and you generate graphics over the DXF file: the display model layers wont load into the DXF file (as expected) but in one of the other currently opened drawings.
Solution: close all other drawings or save DXF as Drawing

2) error message when generating graphics

An error message is displayed and the Display Model doesn't load when generating graphics over a DXF file. Error message shown:

Drawing of Display Model in Map failed. Adding layer failed: layername. 
Failed to retrieve message for "MgLayerNotFoundException".
The resource was not found.

This happens only if the DXF has been saved with a coordinate system. 
Solution: save DXF as Drawing file.

Both issues have been confirmed by Autodesk for Map 2017.

Construction (Cogo) - no feature class available in "Save options"

When you perfom certain CoGo operations you will be presented with the following dialog box:

Cogo - intersection dialog box

In case the Feature class drop down list beneath "Save options"  is empty or certain feature classes are missing - check that you have choosen a suitable profile in the Industry Model explorer. Only  feature classes included in the active profile will be availabe in the drop down list:

create view with unique FID

We have an Oracle view where no unique FID can be retrieved. Without an unique FID Map will not display the data in a form (industry model).

In our situation we only need a unique ID for the sake of the FID requirement by Map. To generate such a unique ID we chose the following approach:

- the view is wrapped by a select statement which includes rownum:

 create or replace view my_view as select  
 rownum fid, t.* from  
 (   
  ... view definition ...  
  ) t;  

As we need to show the data of the view only occasionally performance is not a major concern here.
