2D Line Geometry

Draw | Line

This consists of line tools such as single lines, multiple lines (polylines), Polygons, Rectangles etc.

All 2D curves can be created in the editor by means of inputting accurate geometric and spatial information, typically to indicate either length and angle, or their position.

Any line can be drawn according to length and angle dimensions by inputting the Length and Angle into the edit fields at the top of the editor. This information can usually be input either before or after the curve is produced.

Various drawing tools can be used to assist in the creation of lines. For example, when drawing a line, the keyboard SHIFT key can be used to constrain the drawing of such lines to orthographic (90°) angles.

LIne Bisector

PowerPack | Draw | Line Biscector

This sketch tool creates a line which bisects the angle of two defined locations, relative to a base point.

In the example below, the heavy line bisects the points specified by points 2 and 3.

Point 1 is the intended start point of the line bisector.

The length of the bisector line can be updated in the edit field.

Best Fit Line and Circle

The Best Fit Line and Circle tools are perfect for tracing precise curves over rough images. Both tools allow the designer to over sample a collection of points to account for fuzzy data.

Highlights of the Best Fit Line and Circle Tool:

Best Fit Line

Enter an arbitrary number of points to create a best fit line terminating with right click.

Best Fit Circle

Enter an arbitrary number of points to create a best fit circle terminating with a right click.

You may also select a polyline or curve where the tool will best fit the object into a circle.

Rectangles & Polygons

Draw | Polygon

Rectangles and Polygons are compound objects which can either be drawn as single line objects or as polylines. In instances where these objects are drawn as Smart Polygons, their overall geometry can be modified using the Inspector. In instances where these objects are drawn as Single Line objects, only their individual geometry can be modified.

Objects such as Rounded Rectangles provide an option to blend the vertices, thereby creating a slot, shown below.
