Drafting with DynaScape is made easier by using a small but powerful tool called an Inference Engine. As the name suggests, this tool allows the program to infer specific reference points found on existing objects in a drawing. By referencing these locations, such as endpoints and midpoints of lines, or origins and quadrants of circles, you can create accurate arrangements of entities, without having to enter precise location coordinates. By turning the Inference toggle on, tools and functions that can use inference will automatically snap to available inference points that it finds as your cursor gets close to them. The controls that govern Inference can be seen (or edited) by right-clicking on the Inference toggle and selecting Properties or by opening the Inference Settings panel (Environment | Inference Settings).
Important:
Other CAD software may refer to Inference or Inference Settings as object snaps.
Eight different inference locations are listed and active in the Inference Settings panel, above. In most cases, you will leave these settings as they are to give you the most Inference locations to choose from.
Not all entities have all the above attachment points. Lines, for instance, only have “End”, “Midpoint” and “On” attachment points. Where two entities overlap, a new location, “Intersect”, is created. As you use DynaScape you will see which of these object locations apply to the various entities in a drawing.
