Drawing and Editing
Drawing Bézier curves
Choose the preferred mode for drawing curves.
- In OCAD mode, only the direction of a dragged tangent is used. The distance from the normal vertices to the curve vertices is calculated automatically. This is the recommended mode.
- In Illustrator mode, the length of the dragged tangent is used to calculate the distance of the curve vertex.
Convert freehand to curve when drawing
Check this box to convert lines and areas to curves when drawing in freehand mode. Otherwise they remain as polygons. The tolerance settings Smooth when drawing freehand determine the smoothing level.
Close area objects when drawing
OCAD closes areas object automatically when drawing. If start and end point are different then OCAD add an end point with the same position as the start point.
Choose Close Area Objects in Object -> Topology to close already drawn area objects.
Following existing objects
Uncheck this option if side lines of double lines should not be traced by following existing lines.
- Select objects: This tolerance defines the maximum distance on each side of a thin line where you can click to select it. Objects with a thicker main line than the tolerance can be selected by clicking on the entire line width. The default value is 3 pixels.
- Snapping: This tolerance defines the maximum distance a vertex is moved by using snapping. The default value is 5 pixels.
- Join when drawing lines: This tolerance defines the maximum distance a vertex is moved to join another line end. The default value is 0.25 mm.
- Smooth when drawing freehand: There are three smoothing levels for freehand drawing mode: slightly, medium and strong. They correspond to 0, 1 and 2 in earlier OCAD versions.
- Change to Bezier curve: This tolerance defines the maximum distance the vertices can move away from the original line by changing from polyline to Bezier curve. The default value is 0.10 mm. Note that the distance between the curve and the polyline can be greater between the vertices.
- Smooth (generalization): This tolerance is used by the Douglas-Peucker smoothing algorithm. Vertices that are closer to the direct line between the previous and the next vertex are removed. The default value is 0.05 mm.
Set the cursor color to black, red, blue, purple or yellow.
Set the mark size to normal, large or very large and choose a mark color.
Enable live preview
Enable this option to show the real line width by drawing line objects.
Check this option if the map view should automatically scroll if you drag out of the drawing area. Uncheck this option if you have a slow PC.
