Draw a vector Bezier curve

 

1. If they are not already selected, select the following icons:

2. If no Pick Color is selected, Scan2CAD will draw the Bezier curve in black.

If you want to draw in any other color, select a Pick Color.

3. Choose a line width using Vector Edit Menu > Pen Type > Pen Width.
4. If you want to draw the Bezier curve using a grid, set a Grid Snap Distance.
5. If you want to draw the Bezier curve using snaps, make sure that the End Point Snap and/or Between Ends Snap are turned on.
6. Click at the first point of the Bezier curve.
7. Click at the next point you want the Bezier curve to pass through. A dash line joins the two points.
To undo it, right click and select Undo Last Segment.
To cancel the Bezier curve completely, right click and select Quit.
8. When you finish the Bezier 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.

For example, let’s say you are drawing a heart 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 Bezier 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 Bezier curve:

(You can also make points sharp after drawing the Bezier curve. See the note at the bottom of this section for instructions.)

9. Repeat Steps 7 and 8 until you have drawn all the points the Bezier curve must pass through:

10. Right click.

 To end the Bezier curve at the last point you entered, select Complete Bezier from the menu.

 To close the Bezier curve, select Close Bezier from the menu.

Scan2CAD automatically closes the Bezier curve.

 

Click to undo.

 

You can adjust the shape of the Bezier curve using its control points.
You can make a point in a Bezier curve sharp after drawing the curve, as follows:
1. Press A on your keyboard to turn off Attach End Points.
2. Press E on your keyboard to display Bezier control points.
3. Use Move Grab Point to move the Bezier control points until you have a sharp point.
4. Press A on your keyboard to turn Attach End Points back on.
If the Bezier curve is displayed in pale blue, vectors are set to display by type. Press C to toggle between displaying vectors by color or by type.
Some CAD and CNC programs don’t support Bezier curves. If this is the case (the DXF reads in strangely or won’t read in at all), select File Menu >  Vector > DXF Export Options > Bezier -> Arcs. When you save your vectors as  DXF, the Bezier curves will be converted to arcs.
