Drawing Tools¶
The drawing tools are used to create and modify entities such as lines, circles, etc. in a drawing. Commands can be selected from the menu, toolbars or entered via the command line. Right-click anywhere in the drawing window to display a popup menu showing the history of tools used from the menus or the toolbars with the most recent tool being on top of the list. The command line input is not shown in the history.
Several drawing tools have options or require additional parameters that appear on the Tool Options toolbar. The Tool Options toolbars are shown in the table below. If using the command line, the same tool options are available via the toolbar or the command line.
Important
Ensure the Tool Options toolbar is enabled. From the menu select Widgets -> Toolbar -> and enable Tool Options. The Tool Options toolbar will not appear if they are not enabled.
Line¶
The Line tools are used to create individual straight entities - a line - or multi-sided entities of individual line segments (other than the Rectangle, which is a polyline - see below).
Circle¶
The Circle tools are used to create closed curved entities with a single center point.
Curve¶
The Curve tools are used to create opened curved entities with a single center point (simple arc) or two foci points (elliptical arc). The Curve category also includes the Spline tools - curves defined by two or more points - and the Freehand Line tool.
Ellipse¶
The Ellipse tools are used to create closed curved entities with a two focal points.
Polyline¶
The Polyline tools are used to create open or closed objects consisting of straight or curved connected segments. All segments that create the polyline are treated as a single entity. Closed polylines are created when the final segment is connected to the first segment of the polyline.
Select¶
The Select tools are used to select or deselect one or more entities.
Note
- When no drawing tool is active (mouse pointer is displayed), the default [Left Button] mouse action is to:
- Select/deselect one or more entities by clicking on them, or
- Select multiple entities with a window. See Select Window below.
See Selecting Entities in Fundamentals for more details on selecting and deselecting entities.
Dimension¶
The Dimension tools are used to annotate a drawing by labelling the length, width, height, and/or angle of a line entity, the diameter of circle entity, or radius of arc entity. Refer to Annotating a Drawing in the User Guides for more details.
Modify¶
The Modify tools are used to change and alter one or more existing entities, individually or in groups.
