Use REM Refine Mode to modify the geometry of a REM region or primitive object.
When a REM object is in Refine Mode, only the vector image of the object is displayed, which makes it easier to correct the geometry.
Note: Enhanced bitonal region objects cannot be refined.
Some typical situations for using Refine Mode:
- After you define a region object, you realize that the boundary of the region needs some adjustment to include the right pixels.
- You define a primitive object and it does not end where you expected. For example, you selected a line, and the primitive crosses an intersection when you want it to end at the intersection.
Grip Behavior
Region objects and primitive objects have different grips to use for resizing.
Region Objects
- REM polygonal, rectangular, and diagonal region objects have grips on each vertex and midpoint. You can reposition each vertex independently of the others. If you reposition a midpoint grip, the affected segment is broken into two segments. This operates like the AutoCAD Raster Design toolset Image Mask object. All other grip operations, such as scale and stretch, use AutoCAD polyline grip behavior.
- A circular region object has five grips: one grip at the center of the circle and four on the circumference. REM circular region objects behave like AutoCAD circles. If you move the center grip, the entire circle moves. If you move one of the grips on the circumference, the radius changes.
Primitive Objects
- A line primitive has three grips: one at each endpoint, and one in the center. If you move the center grip, the entire object moves. Grip editing a REM line is the same as editing an AutoCAD line.
- A circle primitive has five grips: one grip at the center of the circle and four on the circumference. Grip editing a REM circle is the same as editing an AutoCAD circle. If you move the center grip, the entire circle moves. If you move one of the grips on the circumference, the radius changes.
- An arc primitive has three grips: one at each endpoint, and one at the midpoint of the arc. Grip editing a REM arc is the same as editing an AutoCAD arc.
