AutoCAD Map 3D

[#1]

Hi,

My first post here, hoping for a bit of help with something that will hopefully turn out to be quite simple. 

The attachment can probably explain this better than I can, but basically I have a series of polygons for a dataset that I need to export as an SDF. One of these polygons has a hole in the middle which I need to preserve. If I export it as it is, then I will get two polygons, one inside the other that will sit one on top of the other. What I want is to keep it looking as it is there.

Any ideas?

Thanks in advance

Hi,

start command MPOLYGON and convert the polyline to polygons ==> that will (should) recognize the island-polyline as island for the MPOLYGON-object.

The MPOLYGON-objects can then be exported including these islands.

The other option would be to first create a topology and start MAPEXPORT with the option to use the topology for export and not the geometry-objects.

Many thanks Alfred, the MPOLYGON command works just fine. I've had to have a closer look at the polylines as one was crossing itself, but that has done the trick for now.

Thanks very much!
