  • How to make a GDB to CAD template useable for any GDB file without having to set in the Reader's GDB manually each time? And how to make each individual feature class it's own layer in CAD?

Hi everyone!imageMy current workspace here is designed to convert Esri GDB feature classes into CAD DWG files.

 

As of right now it works but there's a few issues I couldn't solve:

 

  1. The workspace is meant to work as a template without having the user to have to manually change what file they'll be reading each time. Currently it's hard set to a specific point file.
  2. There should only ever be 1 single GDB file being processed at a time, but the GDB file is expected to have multiple feature classes
    1. Within each GDB I'm also expecting that I have to deal with incompatible feature classes which simply need to be skipped.
    2. Valid feature classes will all have the following attribute fields:
      1. FillColorField
      2. StrokeColorField
      3. LayerTypeField

 

So I need this template to only process feature layers in a GDB where it contains those 3 field and those fields are not null or empty.

 

Each feature layer needs to be rendered into their own respective layers.

  • E.g. If a GDB file with polygon and point layers need to be converted into DWG with a layer for each of them

My understanding is that I need to create an attribute called CAD_Layer or something but I couldn't it out.

 

I also need to be able to run this workspace from the command line or something as I'm building this app for users who do not have any knowledge on FME workbench and are only expected to just click on a button and let the workspace convert things for them.

One thing I always do when I have to deal with multiple GDBs is I use Creator to initiate the workspace and I use Feature Reader to read GDB.

In the setting under Output select Single Output port (This make it to where all features inside that gdb came out through Generic port). Expand Attribute and Geometry Handling, <Generic> Port, and put Attribute to Expose: FillColorField StrokeColorField LayerTypeField

 

You will need to create User Parameter for GDB Path, supply this parameter into the Feature Dataset.

This will allow you to run the GDB dynamically. (User or External Program need to provide this)

 

However I'm not familiar with how to get this to run on command line, as we utilizing FME Server, and all our Users just copy paste the file path and hit run to get what they need usually.

Hopefully this can help you in some way.
