System Overview
MicroStation PowerDraft can be operated as a 2D general purpose drafting application or as a full 3D modeling application. The first few chapters address 2D drafting. 3D will be introduced later. Many 2D commands also apply to 3D.
Positioning the Pointer
MicroStation PowerDraft receives its graphic input from a mouse or digitizer. This manual uses the mouse as the graphic input device.Menus
MicroStation PowerDraft commands appear on menus. Each menu has a specific purpose. For example, the File menu allows you to select a command to open an existing design or create a new one.Some menu selections cause a dialog box to open. A dialog box provides further options for a menu command.
Some menus selections open tool frames or tool boxes. A tool box contains icons, tools, which you click to invoke a command.
Elements
MicroStation PowerDraft allows you to create a design using basic building blocks called elements. Other CAD software applications refer to these building blocks as objects, entities or primitives. Elements include lines, circles, arcs, curves, points, text and more.Cells, often referred to as symbols or blocks in other applications, are created from elements and stored in libraries for later use.
A series of elements such as lines, arcs or curves can be connected into complex chains. The complex chain can then be treated as a single element, similar to a polyline.
Levels
Y to can have an unlimited number of different levels, or layers. A level can be thought of as one sheet of mylar. All elements with the same level number are on the same sheet. Turning on one level is likeviewing only one sheet. Turning on a second level is like placing a second sheet on top of the first.
