My Location indicator An indicator in model space that shows your current location in GPS-enabled systems. Named objects include linetypes, layers, dimension styles, text styles, block definitions, layouts, views, and viewport configurations. Named objects are stored in definition symbol tables.
VIEW node A type of object snap that locates point objects, dimension definition points, and text origin points. See also associative dimension and exploded dimension.
The direction of the normal indicates the front, or outer surface of the face. A B-spline curve or surface defined by a series of weighted control points and one or more knot vectors. See also procedural surface and generic surface. Formerly called entity. See also custom object and proxy object. Object Snap mode A method for specifying commonly needed point locations on an object when you create or edit objects. With object snaps, you can specify the precise location of the center of a selected circle, or the intersection of two curves.
See also running object snap and object snap override. See also Object Snap mode and running object snap. ObjectARX Runtime Extensions A compiled-language programming environment that runs under the Windows operating system used for developing product-specific applications and extensions.
OLE For object linking and embedding. An information-sharing method available in the Windows operating system in which data from a source document can be linked to or embedded in a destination document. Selecting the data in the destination document opens the source application so that the data can be edited. See also embed and link. For example, the origin of a Cartesian coordinate system is where the X , Y , and Z axes meet at 0,0,0.
Ortho mode A setting that limits pointing device input to horizontal or vertical directions relative to the current snap angle and user coordinate system. See also snap angle and user coordinate system UCS. These settings can be modified and applied to other layouts. Dockable windows include the command line, status bar, Properties palette, and so on. PAN See also zoom. Paper space is used for creating a finished layout for printing or plotting, in contrast to drafting or designing. You design your model using the Model tab.
Under Windows, you can load and unload partial CUI files as you need them during a drawing session. PC2 file The complete plotter configuration file. PC2 files contain all plot settings and device-specific settings that were saved in previous versions of AutoCAD-based products that run on the Windows operating system.
PC3 file Partial plotter configuration file. PC3 files contain plot settings information such as the device driver and model, the output port to which the device is connected, and various device-specific settings, but do not include any custom plotter calibration or custom paper size information.
PCP files contain basic plot specifications and pen parameters that were saved in previous versions. Plot settings that are stored in a PCP file include pen assignments, plotting units, paper size, plot rotation, plot origin, scale factor, and pen optimization level. See also PC2 file and PC3 file. The performance tuner examines your graphics card and 3D display driver and decides whether to use software or hardware implementation for features that support both.
Because its control vertices are not tangent to the object, if the curve is reshaped, it stays smooth and does not create kinks. See also clamp curve. Because its control vertices are not tangent to the object, if the surface is reshaped, it stays smooth and does not create kinks. See also clamp surface. Objects appear smaller when the distance from the observer at the view point to the view center increases. Although a perspective view appears realistic, it does not preserve the shapes of objects.
Parallel lines seemingly converge in the view. Physically correct lights attenuate as the square of the distance. Photometry is the science of measurement of visible light in terms of its perceived brightness. When it calculates indirect illumination, the renderer traces photons emitted from a light. The photon is traced through the model, being reflected or transmitted by objects, until it strikes a diffuse surface.
When it strikes a surface, the photon is stored in the photon map. For example, on a two-button mouse, it is the left button by default. See also pre-selection set. PLAN playback The process of executing the actions stored in a previously recorded action macro.
The file containing custom plotter calibration and custom paper size information associated with plotter configuration file. A location in 3D space specified by X , Y , and Z coordinate values.
An object consisting of a single coordinate location. POINT point cloud A large collection of points placed in model space that create a 3D representation of objects or geographic features. See also crosshairs. See also polar tracking. See also Polar Snap.
Although you can continue to create polygonal and polyface mesh for example, by setting MESHTYPE to 0 , the newer, more flexible mesh type is recommended. See also crossing selection and window selection. Also called pline. By default, a polysolid always has a rectangular profile. You can specify the height and width of the profile. Plot styles are applied at plot time. Plot styles are defined in plot style tables and apply to objects only when the plot style table is attached to a layout or viewport.
You can create primitive 3D solids and meshes. These include marble and wood. Also called template materials. Procedural surfaces are the only type of surface that can be associative.
This term is associated with the model documentation feature. See also custom object and object enabler. On the ribbon, pins keep panels expanded.
In the application menu, pins keep an item in the list of recently viewed items. PWT A template file format used to publish drawings to the Web. Quick View A tool to preview and switch between open drawings and layouts in a drawing.
Quick View image A thumbnail image of a drawing, layout or model space that is displayed using Quick View. Ray tracing traces the path of rays sampled from the light source. Shadows appear where rays have been blocked by objects. Ray-traced shadows have sharp edges.
Reflections and refractions generated this way are physically accurate. You can also refine specified mesh faces without resetting the baseline level of smoothness for the object. Also called specular color. You can create regions from objects that form closed loops. They area commonly created in order to apply hatching and shading, and to extrude in 3D. After the geometry is edited, the constraints are either removed or retained based on whether the constraint is still valid for the edited geometry.
When you click this grip, a drop-down list of the lookup values for that lookup property column in the lookup table is displayed. When you select a value from the list, the corresponding input property values are assigned to the block reference.
Depending on how the block was defined, this usually results in a change in the block reference's geometry. RGB For red, green, and blue. A system of defining colors by specifying percentages of red, green, and blue.
Multiple ribbon panels, belonging to one workflow, are grouped together under a ribbon tab. A ribbon tab contains groups of multiple ribbon panels, each belonging to one workflow.
A ribbon panel contains buttons and controls, related to a task. A single row is one cell in height. A low roughness value simulates a shiny object metals, some plastics. Typically, one endpoint of the rubber-band line is attached to a point in your drawing, and the other endpoint is attached to the moving cursor. It provides a "best guess" color for each rendered pixel.
The renderer first samples the scene color at locations within the pixel or along the pixel's edge, then uses a filter to combine the samples into a single pixel color. Script files are created outside the program using a text editor, saved in text format, and stored in an external file with the file extension. For example, if an annotative object such as a label supports two annotation scales, it has two separate scale representations in two views displayed at two different scales.
In a dynamic block definition, the geometry associated with an action. Shadow maps don't show the color cast by transparent or translucent objects. In contrast to ray-traced shadows, shadow maps have softer edges, and take less calculation time at the expense of accuracy.
See also sheet set. A sheet list table can be generated automatically with the Sheet Set Manager. The function keys F1, F2, and so on are also shortcut keys. On the Mac, Command-S saves a file. The function keys Fn-F1, Fn-F2, and so on are also shortcut keys. The shortcut menu and the options it provides depend on the pointer location and other conditions, such as whether an object is selected or a command is in progress.
For programs that run under the Windows operating system, shortcut menus are now called context menus. They are also sometimes called right-click menus. A shot can contain a static thumbnail of the saved view or camera motion that can be played back as an animation. ShowMotion User interface element where you can access named views shots that are stored in the current drawing.
The named views shots are organized by sequences and can contain movements. The sky displays with a color gradient between the sky horizon nearest to the horizon and the sky zenith opposite the horizon. See also ground plane. A slide-out panel contains additional tools and controls. Objects with higher levels of smoothness have more faces, or tessellations.
The snap grid does not necessarily correspond to the visible grid, which is controlled separately by GRID. SNAP snap resolution The spacing between points of the snap grid. A spatial index is used to locate what portion of the drawing is read when you partially open a drawing.
Saving a spatial index with a drawing also enhances performance when working with external references. See also intensity. This curve, called a spline-fit polyline, passes through the first and last control points unless the original polyline was closed.
STB file For plot style table file. Contains plot styles and their characteristics. As a mesh object is smoothed, the number of subdivisions increases. Subscription Center Subscription members can access the latest releases of Autodesk software, incremental product enhancements, and additional services.
See also view category. The surface indication leader SIL is used to point to surfaces or faces rather than the edges of components. Symbols are inserted in drawings as blocks. When this happens, the tab list button appears. TABLE table break The point at the bottom of a table row where the table will be split into a supplementary table fragment.
