Question

Convert Polygon (Area) to Surface


Hi,

 

 

From my reader I get an area feature (determined by the 'GeometryFilter'), but for my writer I need a Surface Feature. How do I convert an Are to a Surface?

 

 

Thanks a lot!

 

Michel

Hi,

 

 

 

Is your object 2d or 3d.

 

If its 2d u can extract some vertices (preferably cornernodes) and us a surfacemodeller. If that is what u are looking for thats is.

Hi Michel, probably the FaceReplacer transformer is what you are looking for.

Hi gio,

 

If my object is 3D, then how can I convert the Area to Surface?

Hi @fang​ have you tried using the 2DForcer transformer to remove any z elevation?

Hi@daraghbroderick, ​my Area is 3D and I need z elevation, you could see it from my uploaded pictures. The polygon is made up of four boundary lines including an Arc. My ultimate goal is to build solids and it seems that only faces can build up solids, but I haven't find a solution to build faces in 3d. Do you know how to do these? Thanks a lot.

Maybe this answer is not directly related to this specific question but still:

I have an ifmeMultiarea (polygon parts) which I wnat to turn into a surface. Since FaceReplacer is time consuming and error prone because of generating allt the triangles. My workaround is saving the MultiArea as an obj and reimporting it, now it is a Surface :)
