Active only when the current environment is a drawing.
•Line - A single line segment. Lines can be one segment or a series of connected segments, but each segment is a separate line object.
•Polyline - 2D/3D line composed of line and arc (bulges) segments. Polyline is specified by an array of Vertexes (points). When the Polyline has thickness then the extrusion vector of the polyline defines the direction of the thickness. Polylines can be Open or Closed, can be SPLine and be filled with a color or a hatch.
•Circle - A full circle is defined by its CenterPoint and its Radius. Circle is drawn in the plane that is defined by CenterPoint and ExtrusionVector.
•Point - An object which occupies a single point in the coordinate system. The display of the point is inherited from the document Point Style property and can be set by clicking Drawing>Point Styles...
•Rectangle - A rectangular object defined by an insertion point, height and width.
•Text >
Single Line of Text - Text inherits its style from the document Text Styles collection which can be edited by clicking Drawing>Text Styles... Text entities do not have font properties directly but inherit the font and font properties from the associated Text Style.
Multiline Text (MTEXT) - A mutiline text entity.
•Image Frame - Used to render images in the document. Images may either be linked or imbedded in the drawing file. The image frame defines the location and size of the displayed image. To imbed an image you must edit the document Images collection Drawing>Images.
•Construction Ray - A line entity defined by its starting point and an angle.
•2 or 3 Pt Arc - A circular arc defined by the center point, the radius, the start angle and the end angle. An arc is always drawn anti-clockwise from the StartAngle to the EndAngle. The StartPoint and EndPoint properties of an arc are calculated through the StartAngle, EndAngle and Radius properties. The ExtrusionVector is always vertical to the arc. Arc is drawn in the plane that is defined by CenterPoint and ExtrusionVector.
•Ellipse - Draw an Ellipse.
•Cloud - Draw a cloud.
•Insert Block Into Drawing - Opens the Inserts dialog. You can then insert an existing block into the drawing or browse to another file to insert in the drawing.
•Write Block to File - Writes the selected insert out to its own file prompting you for the file save as name and location as well as the new basepoint for the drawing.
•Create Attribute Definition - A tag/value data pair that can be included in a block to display editable text.
•Make a Block - Select entities and group them into a unit called a block. The block resides in the document Blocks table. To display a block we Insert an instance of the block into the drawing at some point, scale, and rotation.
•External Reference Manager - Other drawings may be displayed within the drawing space and maintained as separate files. These are called Externally Referenced (XREFS) drawings. The externally referenced drawing cannot be edited in the current drawing, only viewed, positioned, scaled and rotated. This function opens the External Reference Manager dialog.
•Edit Attributes - Allows editing of the attributes of the selected insert of a block.
Dimensioning is the process of adding measurement annotation to a drawing. There are many ways to dimension objects and many ways to format dimensions. You can create dimensions for a wide variety of object shapes in many different orientations. You can create dimension styles to format dimensions quickly and ensure that dimensions in your drawing conform to industry or project standards. Dimensions show the measurements of objects, the distances or angles between objects, or the distance of a feature from an origin you specify. There are three basic types of dimensioning: linear, radial, and angular. Dimensions can be horizontal, vertical, aligned, rotated,angular. A linear dimension measuring the distance between two points which is displayed parallel to the points being measured. In aligned dimensions, the dimension line is parallel to the extension line origins. The extension line origins are specified using the DefPoint1 and DefPoint2 properties.
