Error importing shapefile

Altair Forum User

Hello,

 

I am now trying to import shapefile to a WallMan in order to build a 3D model for propagation computations. During the import i get an error

 

I can't figure out what exactly the programm doesn't want to except, because when I use another files, which have the same structure it works... Can please someone explain to me what the shapefile should contain in order to be succesfully import to WallMan?

 

The shapefiles I also add for you:

- the first one (file1) is the actual file I have and need to use (contains more information)

- the second one (file2) is the one I have downloaded from the internet, looks simpler and still does not work well

- the third (file3) was again downloaded from the internet but for some strange reason sucessfully imported by WallMan

 

Best Regards,

Yaroslav

Hello,

 

the shapefile should contain the buildings as closed polygons. The polygon should not intersect itself, which means that the sequence of corners is not correct.

According to the error message shown from your side this seems be to the reason why the building cannot be imported.

 

If possible we recommend to use the MapInfo format for import in WallMan.

But the shapefile format will also work if the buildings are defined correctly.

 

Best regards
