Mesh from contours - for an underground cave

I have a file consisting of line string elements that define the profile of an underground cave. I would like to create a mesh from this to then run though CloudCompare to see where a later point cloud survey differs.

I am struggling to use the Mesh tools in Microstation to create an element that will take account of the overhanging roof.

Can anyone suggest a solution?

Using the available tools results in a lot of triangulated elements running from the floor to the ceiling of the cave

  • could you post DGN or an screenshot at least, what the line strings look like?

  • Please confirm the product / version your using and as Peter suggest provide an example.

    Have you tried selecting all the profiles and then use the 'Mesh From Points' tool, with the Tool setting Direction:Tunnel, placing data points in the cave profiles to define the direction.

  • Hi

    I'm afraid I have no idea how to post a screen shot! Any tips and I'll upload something tomorrow and give a more detail reply

  • Essentially the methods suggested result in triangulation extending from floor to roof in many locations. I guess what I am looking for is for the software to simply triangulate / mesh only between immediately adjacent contours. I have no problem with doing this on a typical ground surface but the overhanging nature of the cave roof seems to be the issue
