Removing colinear points on a line string?

Excellent illustration!

Is there a tool in MicroStation that will let me delete colinear vertices?

Whence did those excess vertices originate?  That sort of geometry cleanup tool is provided by GIS tools, such as Bentley Map. 

Hi Jon,

I extracted the opening boundary of a mesh surface. I had planned on using it to trim another surface but I am getting crashes. I think this is due to an excessive amount of computation required by the additional vertices. Naturally, I would like to be able to do this with the Bentley suite I already have but I will add Bentley Map to the list of Bentley suites I will need to investigate when I have the opportunity to do so. Thanks for the reply.

You might want to try using the Cleanup Mesh tool before extracting the boundary. If you check the Coplanar and collinear options it will simplify the mesh and then the extracted boundary should be cleaner.

I would just make a copy of the mesh, apply the Cleanup Mesh tool to the mesh copy, extract it's boundary, and delete the mesh copy.
