Converting Areas, Ellipses and Arcs to lines,

Hi,

 

 

you can use the ArcStroker for this. In some cases you might also want to add a GeometryRefiner to merge contiguous paths/segments into a single geometry before writing it.

Many thanks David for the help. Arcs and ellipses are converted to Areas\\Lines

 

 

 

 

Now, how lines can be converted to polygons or vice versa? In the ArcGIS, all types of features can be conveted to one another.

 

 

 

 

In FME:

 

 

How lines are converted to polygons?

 

 

How polygons are converted to lines?

Hi,

 

 

you can use the GeometryCoercer to convert to/from lines and polygons.

 

 

For non-closing polylines, you can use the LineCloser first.

Hi Jamal,

 

 

There are many transformers, I think you can do almost all geometric manipulations you want. For example, regarding the image of Feature To Polygon tool, "LINE INPUT" is equivalent to the Intersector + AreaBuilder and "POLYGON INPUT" is equivalent to the AreaOnAreaOverlayer.

Thank you David and Takashi for the massive help,

 

 

All commands you have provided are very useful. I couldn’t figure out why the “AreaOnAreaOverlayer” doesn’t work? Which special inputs must be provided to this transformer?

 

 

 

Perfect. It works fine.

 

 

 

 

Very much appreciated

I couldn’t choose BOTH answers (David and Takashi)  as best answers.

hi,

 

 

 

You might want to keep in mind that arcstroking may lead to loss of topology ( if that is important that is).

Thanks Gio for the input.

 

 

Sure, I consider that some transformers do change the geometry of objects (features).
