So I have a very strange and very confusing problem.
I have exported a DXF from the software QGIS, this dxf is of building footprints.
Within the Qgis software it is a .gpkg vector file of polygons and states the “feature count” is 7519.
But when I export the layer as a DXF and then open it in Rhino, Rhino states there are 7520 hatches.
This is a huge problem when I am trying to extrude the buildings to a list of their heights and only have 7519 values for that so the data tree is ruined.
What is more bizarre is that sometimes when i select the all of the hatches in rhino it claims there are only 7519 hatches but then instantly if I deselect them and select them again it will say there are 7520.
I have done a number of things to work out what is happening:
- SelDup - but there are no dupicates apparently.
- I exploded the hatches and then checked the bounds of the areas of the surfaces (in GH), there was 1 surface with an area of 0.000807, but when i culled this from the list and baked the extruded geometry and cross checked the correctness of the building heights they was not the correct so I dont believe this tiny surface was the problem, because the item also showed up in the feature count in QGIS.
- I have tried importing the dxf in all the different ways but no luck.
I have now run out of ideas and was hoping somone might have any thoughts.
Here is the .dxf attached.
