Convert a line to an arc

An arc is also known as a semicircle, or a closed segment of a curve. In Scan2CAD, you can change a straight line to an arc by following these simple instructions:

Before After


1. Click or select Vector Edit Menu > Modify > Line to Arc.
2. Click on the line to convert, making sure it is within the Grab Snap Distance.

If View Vector Ghosts is selected the original line is shown as a gray “ghost”.


Click to undo.

If a Pick Color is selected you can only convert lines that are the same color as the Pick Color.
Line to Arc does not convert lines that are parts of polylines or polygons. To convert a line that is part of a polyline or polygon to an arc you must first explode the polyline or polygon using Vector Edit Menu > Modify > Un-Make Polylines.

Line to Arc does not convert arrow lines, dash lines, dash dot lines or hatch lines. To convert an arrow line, dash line, dash dot line or hatch line to an arc, turn it into a continuous line type first using Vector Edit Menu > Modify > Line to Alternative Line ().
