Adding Objects to DTM

In this description, the term DTM actually refers to a DTM set, meaning an Existing DTM as well as (potentially) a Proposed DTM and a Cut and Fill DTM.

After a DTM has been created, it keeps track of which objects serve as data. You can add selected points and/or polys to the DTM by choosing Object > Add to DTM.

This act of adding to a DTM doesn't change what kind of DTMs are created in the DTM set. If the DTM set only consists of an Existing DTM, and you add, for instance, a poly whose purpose is a road, then you still have to select the DTM set and cause the Proposed DTM to be created. This cannot be done in the Standard version of SimuTerra.
