Introduction
This tutorial will show you how to convert a MapInfo TAB (MITAB) (*.tab) file to Bentley Microstation DGN (*.dgn) format using FME.We'll see how symbology can be modified with the DGNStyler transformer,and split the output data into Microstation levels based on a category for each zone.We'll also look at setting Microstation tags and changing the seed file from 3D to 2D.
Step-by-Step Instructions
To complete the process described in the video,you will need to carry out the following steps.
1) Start FME Workbench
In Windows this is found under Start > All Programs > FME Desktop > FME Workbench
2) Select Generate Workspace
This is found on the Create Workspace section of the FME Workbench interface.Alternatively,use Ctrl+G as a shortcut.
3) Browse to and select the source (Reader) dataset
Select MapInfo TAB (MITAB) for the reader;do this by typing the name into the field until it appears within the dropdown list.Navigate to the Zones.tab file and select it.
4) Set the output (Writer) format to Bentley Microstation Design (V8) DGN
Select Microstation DGN for the format for the writer;do this by typing the name into the field until it appears within the dropdown list.
5) Set the output dataset location
In the video,it is set to C:\FMEData2018\Output.However,you can set your output location to whatever best suits your directory structure.
6) Modify the output (Writer) Parameters
For the writer parameters,I can set various parameters to do with how the DGN data is created by clicking the Parameters button.
7) Modify Symbology using the DGNStyler (optional)
If I wanted to change the symbology,I would use the DGNStyler transformer.In this case we will keep the original symbology.
8) Modify the output (Writer) Properties
When I open the ouptput properties dialog box,I can see that the output is all being written to a single level called 'zones'.I will change this to take the 'ZoneCategory' of each feature as the level it should be written to.Now I will get a separate level for each category of zone.
9) Click the Run button on the toolbar
Run the workspace by clicking on the green play button.This carries out the translation.
10) View the DGN file in a MicroStation Viewer
Once complete,use a file browser to locate the output dataset.If we use a 3rdparty CAD viewer such as MicroStation Viewer to inspect the data,we will see that the data in the DGN file has been written as a separate level for each category of zone.
