draw mesh

Hi. As your screen shot shows, the DTM is a mesh object that must reside on the level named "DTM". Meshes can be created using the tools found in the Mesh Modeling task. To recreate the mesh from the example project shown in your screen shot, you could use the Place Block tool in the Surface Modeling task (not from the Drawing or other task), then use the Mesh From Element tool in the Mesh Modeling task. For the triangular facets, set Max Num Edges to 3 on the Mesh from Element settings box that pops up. Control the size of the facets with the Max Edge Length setting. You can find more information about these tools in the MicroStation Help file. Of course, in a real world application the DTM would be created with other tools or coming from some other source.
