Autocad dictionary object

The text name key uses the same syntax and valid characters as symbol table names. A key name can be changed using the dictrename function. The following is an example of the output you might see in Text History window after c:ListDictionaries is executed. The AuditInfo object pointed to by auditInfo contains Closes the object. All changes made to the object since it was opened are committed to the database, the object Closes the object and pages it if the object pager is turned on.

All changes made to the object since This member function is used to control behavior for custom objects and entities when saving to previous formats. Custom objects This function gives control of deep clone operations to the object.

In the default implementation, the object is cloned and Turns off or on the Undo recording for the object. If disable is set to true, then Undo recording is Downgrades the object from being open OpenMode.

ForWrite , to being OpenMode. Yes, that is true. The "integer" datatype used in AutoCAD is a 16 bit integer. Base integral datatypes translate as follows: VB6. NET C. NET VB. NET int System. Int16 short short long System. Int32 int integer System. Int64 long long IE. Message 7 of Michael, The dictionaries collection can contain many objects. Dictionaries Debug. Jones www. Message 8 of Very easily.

Try this: AutoCAD. AcadApplication Marshal. Application" ; AutoCAD. And, that's what COM wrapper ends up being created for the built-in dictionary object. And, since those same wrapper interfaces do not support AcadDictionary, the QueryInterface that the Interop performs when you try to cast an AcadObject to an AcadDictionary is failing.

IAcadGroups AnObject;. Message 9 of Ignore my gibberish below about downcasting interfaces. Contrary to what I suggested, AutoCAD always creates the corresponding collection interface when you try to get a built-in dictionary object such as the group dictionary. Any drawing file can be saved as a DWT file. See also initial environment. DSD For drawing set descriptions.

A file format for saving a description of a drawing set that has been assembled using the Publish dialog box. DST For sheet set data. The XML file format used to store the associations and information that define a sheet set. DWF An open, published, and secure file format developed by Autodesk, DWF enables you to combine and publish design data and share it with others. Generically referred to as DWF. DWF underlay See underlay. DXF For drawing interchange format.

An ASCII or binary file format of a drawing file for exporting drawings to other applications or for importing drawings from other applications. See also parameter constraint and annotational constraint.

You create an electronic drawing set by publishing drawings to a multi-sheet DWF file. See also link. It is often accessed by many users and is stored in a shared network location. The file is read-only to users to prevent the data in the file from being changed. An expanded panel contains additional tools and controls.

See also ribbon panel and ribbon. In the case of a block, the block definition is unchanged. The block reference is replaced by the components of the block. If the command line window is undocked, you can display this history by pressing F2 or by clicking the arrow at the right end of the Command Line window. The extended command history contains the same information as the text screen, which can be displayed by entering TEXTSCR or by pressing F2 when the window is docked.

See also extended prompt history. An external reference is a link to the referenced file. Smoothing a mesh object increases the number of facets. Feature control frames always contain at least a geometric characteristic symbol to indicate the type of control and a tolerance value to indicate the amount of acceptable variation. FILL field A specialized text object set up to display data that may change during the life cycle of the drawing. When the field is updated, the latest value of the field is displayed.

Using a photon map to calculate global illumination can cause rendering artifacts such as dark corners and low-frequency variations in the lighting. You can reduce or eliminate these artifacts by turning on final gathering, which increases the number of rays used to calculate global illumination.

Final gathering can greatly increase rendering time. It is most useful for scenes with overall diffuse lighting, less useful for scenes with bright spots of indirect illumination. You turn on final gathering on the Advanced Render Settings palette. See also global illumination. See also interpolation points and approximation points.

See also motion path. Objects on frozen layers are not displayed, regenerated, or plotted. Freezing layers shortens regenerating time. These include color, layer, linetype, linetype scale, plot style, lineweight, transparency, hyperlink, and thickness. Generic surfaces cannot be associative and they are created when associative analytic surfaces are separated or by using the BREP command.

The geographic marker is used as a reference point for all geographic location data in a drawing file. Examples include coincident, collinear, concentric, equal, fix, horizontal, parallel, perpendicular, tangent, and vertical constraints. They are displayed when you select a 3D object. As light hits a colored object in the model, photons bounce to adjacent objects and tint them with the color of the original object.

G0, G1, G2 continuity See continuity. Gooch shading A type of shading that uses a transition from cool to warm colors rather than from dark to light. The grid spacing is adjustable. The grid is never plotted.

GRID See also grid limits. Also called drawing limits. LIMITS grip modes The editing options that you can access from selected grips on selected objects: stretching, moving, rotating, scaling, and mirroring.

After selecting the grip, you can edit the object by clicking or right-clicking the grip instead of entering commands. The ground plane displays with a color gradient between the ground horizon nearest to the horizon and the ground origin opposite the horizon.

See also sky and underground. An interface for developing peripheral device drivers for Autodesk products on Windows. Home view A view that is saved with the drawing and is controlled with the ViewCube tool. The Home view is similar in concept to the default, initial view presented when a drawing is first opened.

Illuminance In photometry, illuminance is the total luminous flux incident on a surface per unit area. See also template drawing. When the parameter values in a dynamic block reference match a row of input property values, the corresponding lookup property values in that table row are assigned to the block reference. See also approximation points and fit points. Islands may be detected as part of the process of creating hatches, polylines, and regions.

They show the shape of the surface as defined by the control vertices. AutoCAD uses the term isolines. KML or keyhole mapping language [reality capture] In the reality capture feature, an XML grammar and file format for modeling and storing geographic features such as points, lines, images, polygons, and models for display in Google Earth, Google Maps, and other applications.

Labels contain data, such as a title, view number, and scale, that is associated with the referenced view. See also callout block. A landing can either be a straight line or a spline curve. You can view layers individually or in combination. A layer index is used to locate what portion of the drawing is read when you partially open a drawing. Saving a layer index with a drawing also enhances performance when you work with external references. These standards include layer names and layer properties.

Also called layer mappings. Multiple layouts can be created for each drawing. The greater the lens length, the narrower the field of view.

Higher levels result in more faces and increased smoothness. For example, a continuous line has a different linetype than a dashed line. Also called line font. When data is linked, any changes to it in the source document are automatically updated in any destination document. See also embed. LL84 coordinate system Common latitude longitudinal-based coordinate system where latitude and longitude are both measured from to 90 degrees.

Longitude begins at 0 degrees at the Prime Meridian in Greenwich, England and is measured from to Latitude is 0 degrees at the equator and is measured from to The cross sections define the profile shape of the resulting solid or surface. LOFT lookup property In a dynamic block definition, a lookup parameter that you add to a lookup table. The lookup parameter label is used as the property name.

Assigns property values to the dynamic block reference based on how the block is manipulated in a drawing. The fixture may be a simple can or a complex armature with constrained joints. It is a measure of how bright or dark that we perceive the surface. The total luminous flux for a lamp is the perceived power emitted in all directions. The acad. You can choose whether the map type is aerial, road, survey, etc.

The map data cannot be saved within the drawing file. Mesh can be smoothed to achieve a more rounded appearance and creased to introduce ridges. No labels are displayed on any of the wedges and they are often the size of the cursor. Typically, a geometric model is created in model space.

A layout of specific views and annotations of this model is displayed on a layout in paper space. A path can be a line, arc, elliptical arc, circle, polyline, 3D polyline, or spline. My Location indicator An indicator in model space that shows your current location in GPS-enabled systems.
