OpenRoads Designer can't find Point Cloud

Hi,

I am going to create a terrain model using the tool "Create from point cloud" in OpenRoads Designer.

I have attached a large point cloud that I have clipped into a smaller area. I then exported the small clip and attached the point cloud clip. When I try to create a point cloud from the clip, I get an error message saying "No point clouds are visible in the current DGN". I have done terrain models from point cloud clips earlier and I can make a terrain model from the big point cloud. In the properties tab it says that the clip is a point cloud...

Would be really grateful for help!
