We are trying to generate solids in a dgn file to work in microestation from a POD file via importing the cloud and using the xyz coordinates tool to import the points before creating a mesh by point, we want to reduce the density of the points to say some 10%, as when trying to mesh the file crashes.
Is there a way in microestation to reduce the density of those points before converting to a mesh?
Unfortunately we don’t have Descartes at present.
In MicroStation in Point Cloud you can change the density of the Point Cloud file, but it will not allow you to change the density of the POD file and create a new POD file. In Bentley Pointools you can use the Density option and the density will be applied across the whole point cloud. In Bentley Pointools you can use a Uniform Filter to reduce the point cloud density on export. The Uniform Filter changes the Spacing to suit your requirement. The Uniform filter will only affect areas of point cloud whose density exceeds your filter setting.
I am guessing that you do not have Bentley Pointools, but I wanted to share the information with you in case you do have Bentley Pointools.

Hi, yes you’re totally right.
Without the right appropriate tool, the only solution was to use small amounts of points to mesh, surface and make solids to then agglomerate the whole.
Without Descartes or Bentley Pointools this solution still works.

Please look at the attached link. It may help you accomplish what you are trying to do.

Double click on your POD file and in Element Information look at the Number of Points in the Metadata section, When you do the Export set your density to the value you want it to be and create your XYZ file. If you convert your XYZ file in Point Cloud and look at the Number of Points in Element Information you will see that the number is less that the original POD file.
