This is more of a new feature request or improvement I'd like to discuss.
I spend most of my time building models for equipment. I enjoy the features provided in TBC to do this and quickly get it exported to our machinery. HOWEVER, before I send a design out to the field I always use the "Swap Triangles" command to make the surface more smooth and more realistic to the actual design or plans.
For instance I will change this:

To this:

When I am done with these changes I will make the surface update "By User" so that the swapped triangles will not go back to the previously undesirable triangles.
Now for the issue. I constantly get updated plans or changes that require me to update and change my models. Well every time I do I need to rebuild the model and therefore go back to swapping triangles that I have previously swapped!!! This is maddening! I will have sometimes spent hours swapping triangles by the time a model is finalized.
Can a simple option be made, perhaps in the properties of the surface/corridor, that I can click to "Maintain Swapped Triangles" and then rebuild and not have to do it all over again.
Please thoughts and ideas. Perhaps there is a solution and I am just not aware of it.
