The Trace tools originate from the stand-alone ScanPro application, which has now been incorporated into TurboCAD Pro. They enable you to create 2D raster-to-vector tracings of inserted pictures (see Inserting a Picture) or of geometric objects.

Trace tools are available on the Tools toolbar, which you can display by right-clicking in any toolbar area and selecting Tools.
Before creating a tracing, it's important to understand the local menu options, since these greatly affect the appearance and quality of the trace.

Trace Options: Settings for trace quality.

Max Gap for Connection: The largest gap which will be closed when connecting lines.

Max Length for Deletion: The largest segment that can be deleted, i.e., breaking the lines on either side.

Ortho Angle: The angle at which line segments will be joined into polylines.

The advantage to grabbing the window is speed, but some artifacts may be left on the image (grid, flyout controls, etc.). When not used, there are no artifacts, and the image size is limited only by system memory. However, the tracing takes longer, especially in render mode.
Preview `Preview Mode: A trace preview will appear in magenta over the image.

Tracing Colors: By default, all colors will be used for tracing. This option is used when you want to trace around only selected colors.

The following two options are relevant only for Trace by Point:

Show / Hide Trace Rectangle: Toggles the display of the tracing rectangle, defined by its aperture size.
Image Modified
Nearest Graphic Only: Traces only the object closest to the tracing rectangle's center, identified by crosshairs.
