Draw a raster PolyBezier polygon

Before you convert the raster image, you have the option to draw a PolyBezier polygon also within Scan2cAD. Here are the steps to do so.

1. If they are not selected yet, click on the following icons:

2. If no Pick Color is selected, Scan2CAD will draw on the raster image in black.

If you want to use another color besides black, select a Pick Color.

3. Choose a pen size using Raster Edit Menu > Pen Type > Pen Width.
4. By default, the polybezier polygon will be solid filled.

To draw a polybezier outline, press Shift+S or deselect Raster Edit Menu > Pen Type > Solid Fill.

5. Click at the first point of the PolyBezier curve.
6. Click at the next point you want the PolyBezier curve to pass through. A dash line joins the two points.
To undo it, right click and select Undo Last Segment.
To cancel the PolyBezier curve completely, right click and select Quit.
7. When you finish the PolyBezier curve, Scan2CAD will draw a curve through the points you have entered. However, in some situations you will want a sharp angle at a point rather than a curve.

As an example, let’s say you are drawing a heart shape and you have just entered the top middle point:

The top middle point should be sharp.

To make it sharp, right click and select Make Last Point Sharp.

When you finish the PolyBezier curve, the point will be sharp:

If you do not select Make Last Point Sharp, a curve will be drawn through the point when you finish the PolyBezier curve:

8. Repeat Steps 5 and 6 until you have drawn all the points the PolyBezier curve must pass through:

9. Right click.

         To close the PolyBezier curve, select Close PolyBezier:

Scan2CAD automatically closes the PolyBezier curve.


Click to undo.
