Pro Engineer/Definitions

A TOP Accuracy. The smallest item that can be recognised by pro/engineer. Usually defined as ratio of the longest diagonal through the model. Typically 0.0012. Active Model Title bar has stars on each side of the name. Will accept menu commands from the side menu. Use CTRL+A or the tick icon to make the window active. Active Window Window with the blue bar, will accept spinning and rendering commands. Plus some info menu picks. Other commands are restricted for use with the active model. Alpha The optional fourth-channel in an RGB image file, typically used for compositing. Ambient Light A light that equally affects all portions of all objects in the rendering scene. Appearance A set of attributes that determine the appearance of a surface. These attributes include color, reflecting ability, transparency, texture, and so forth. Area Offset Offsets a whole or part surface, similar to form. Side walls are added to join the offset area to main surface. Associative Topology Bus A method for transferring data between applications whilst retaining associativity. Axis See datum axis. ATB See Associative Topology Bus B TOP BMP Bitmap BMX Behavioural Modelling Extension Both Sides When creating extruded features the feature is created on both sides of the sketch plane. Boundary Influence Controls how far the boundary condition propagates across a boundary surface. Boundary Conditions Property of surface at edges e.g. tangent/normal to adjacent surfaces or tangent normal to sketch plane Boundary Surface A surface defined using two or more curves. Briefcase A method in Pro/Intralinkcommonspace to collect objects together. Brightness The property of an appearance that determines its intensity after the hue is chosen. Bump Map A one-channel texture map that creates the illusion of surface roughness. Bump Height The height or depression of the bump map features. C TOP C0 continuity example Position continuity only. Curves have a kink at the C0 point and surfaces have a sharp crease along the C0 seam. Abutting curves and surfaces touch one another, but they have no curvature similarities. C1 continuity example Position and tangent continuity. The edges between a ball fillet and its adjacent faces are examples of C1 continuity. C2 continuity example Position, tangent, and curvature continuity. Curves and surfaces are perfectly smooth, and the curvature at the joint between two abutting curves or surfaces is equal. Consequently, the joint is seamless and invisible.

It should be noted solids cannot be copied but the surface information of a solid can be copied to the target model. See publish geometry. CPC Collaborative Product Commerce Cross-section See X-section Create Accesses the feature creation menu Curvature example Curvature is defined as 1/r. A curvature plot measures the curvature at points on a curve. A line is plotted at that point normal to the curve. The length is proportional to 1/r. The line is scaled up to make it easier to see. Cut A feature to remove material from a model. Curve See datum curve D TOP Datum Axis Datum axes are infinitely thin lines that extend indefinitely in both directions. There are usually shown truncated around the parent feature. Axes can be created manually. They are also created automatically when adding hole features, revolved features. They can be defined in intent manger when defining closed sketches. Datum Plane Datum Planes represent infinitely thin flat planes that extend infinitely in two perpendicular directions. For display purpose a rectangular outline is shown. By default datum planes resize to the size of the model. They can be redefined to a specific size or linked to the size of a feature. Datum planes can be used in as surfaces in some surface operations. One side of the datum is coloured yellow and the other side is red. Datum Curve Datum curves represent curves (inc. straight) that exist in space as 2D or 3D entities. They can curve in more than one direction at a time. Datum curves are orange (they appear brown to a lot of users) Datum Coordinate Systems Coordinate systems represent an origin in space with an X, Y and Z defined. The main uses are for offsetting points, creating datum curves from equations and assembling sub assemblies. Datum Point A datum point represents a point in space usually defined relative to a coordinate system Decal A four-channel texture map that consists of a standard color texture map and a transparency (or alpha) channel. See Alpha. Declare Use to link models and layouts. Delete Permanently remove a feature or entity from Pro/Engineer. When used on patterns the original feature is deleted.
