About Objects

There are four kinds of objects in SimuTerra: points, polys, DTMs, and entels (entourage elements).

Points and polys may serve as data for a DTM. When used as data for a DTM, they can either be regular data, used to create an existing DTM, or modifiers, used to create a proposed DTM. Roads, pads, and collars are polys which act as modifiers.

Objects can be edited in some ways by using the items in the Object menu.

DTMs are calculated objects, so some of their characteristics are dependent upon their data. For instance, you cannot change the elevation of a DTM directly; rather, you would need to change the underlying data.

Each object has a layer which it is associated with.

Each object also has a number. The number is unique for that kind of object. For instance, there can only be one point number 1, though there can also be a poly number 1 and an entel number 1.

Each object has a description of up to 31 characters, though the description is usually blank. There is no functionality to the description: you can display it and edit it, but you cannot search for objects with a particular description.

Points, polys, and entels can be locked against dragging; the purpose of this is generally to avoid accidental movement. You cannot lock a DTM against dragging, because you can't drag a DTM to begin with; its location depends upon its data, which can be locked.

Each point, poly and entel can have a color other than black. Each DTM can have multiple colors for multiple purposes, as discussed on the relevant page. The color is used in both 2D and 3D views.

Each object can have a label displayed; what can be displayed in the label depends upon what kind of object it is.
